Description

Natural light cosmetic shield TECHNICAL FIELD

[0001] The present application relates to the field of cosmetic technology, in particular to a natural light cosmetic shield. BACKGROUND

[0002] When people go outdoors, they will be exposed to natural light, which contains harmful light waves. In particular, under the condition of strong sunlight, harmful light waves such as ultraviolet rays can cause great harm to human skin and can cause skin diseases such as black spots and freckles. Women who love beauty are more afraid of being tanned and looking unattractive. At present, people often use special sunscreen chemicals to filter out harmful light waves in natural light, or use sun hats and other tools to block the sun. However, the effect of existing sunscreens and sun hats and other tools is often limited. The use of chemicals such as sunscreen is another burden on the skin, which can easily cause skin pores to become clogged, and the greasy and heavy feeling when using is often not very comfortable. Using sun hats and other tools cannot completely filter out harmful light waves. With the change of the environment, more and more people are used to carrying masks and face masks when they go out, which can block light and dust and to some extent prevent ultraviolet rays from damaging the skin. However, the use of masks or face masks, like sun hats and other tools, cannot completely filter out harmful light waves. Whether it is sunscreen, sun hat, or mask, the function is single and the effect of filtering harmful light is very limited. In addition, natural light contains a large amount of visible light and near-infrared light, which is beneficial to the health of the skin.

[0003] With the development of society and the improvement of people's living standards, the beauty industry has also developed rapidly. Traditional beauty methods mainly rely on chemical drugs or artificial electronic devices. These methods often have certain side effects and risks, and are also very troublesome to use. Chemical drugs have side effects on the skin to some extent, and the products on the market are of varying quality. Consumers need to spend a lot of time and effort to choose and purchase products that may not meet their expectations. Artificial electronic devices such as LED irradiation beauty and laser beauty electronic products must be powered when in use, and cannot be worn when going out, which is very time-consuming and troublesome.

[0004] In summary, there is currently no beauty product on the market that can use natural light while providing sun protection and skin care functions, is easy to use, has good beauty effects, has few side effects, and can be used in a variety of situations. TECHNICAL PROBLEM

[0005] The purpose of the present application is to provide a natural light cosmetic shield that is easy to use, has good beauty effects, and is safe and reliable. TECHNICAL SOLUTION

[0006] To achieve the purpose of the present application, the following technical solutions are provided:

[0007] The natural light cosmetic shield includes a substrate layer and a filter layer, the substrate layer is made of a light-transmitting material, and the filter layer can cut off light waves of a specific waveband incident from a first direction. The first direction is the direction of light from the outside incident on the natural light cosmetic shield when the natural light cosmetic shield is worn on the user's body, such as the face or the neck.

[0008] In some embodiments, the substrate layer is made of a transparent material or a microporous light-transmitting material, such as cloth or gauze.

[0009] In some embodiments, the specific waveband of light waves includes at least one waveband interval.

[0010] In some embodiments, the specific waveband of light waves includes at least a first waveband of light waves selected from the ultraviolet waveband.

[0011] In some embodiments, the filter layer can cut off incident light waves of the first waveband, transmit incident light waves of the second waveband, and reflect light waves of the third waveband.

[0012] The filter layer is a specific filter film layer that can cut off the incidence of specific waveband light waves and allow the incidence of other wavelengths of light waves. The specific waveband of light waves can include at least one waveband interval, with the ultraviolet waveband being the preferred waveband, or it can be a two-interval or multi-interval waveband. For example, the specific waveband of light waves is selected from the 280-400 nm waveband, or the 450-550 nm waveband, or the 600-700 nm waveband. For another example, the specific waveband of light waves is selected from a waveband including the 450-550 nm and 600-700 nm two-interval waveband. For another example, the specific waveband of light waves is selected from a waveband including the 500-615 nm and 900-1800 nm two-interval waveband, such as a waveband that cuts off the 900-1800 nm waveband interval, i.e., blocks visible light from penetrating, while near-infrared light can be transmitted. Or, a more finely divided range of intervals is selected, etc., so that the waveband of light that has a cosmetic or therapeutic effect on the skin can be transmitted through the natural light cosmetic shield to the user's skin. In a more specific embodiment, the filter layer has a cutoff wavelength of 280-400 nm, a transmission wavelength of 400-700 nm, and a reflection wavelength of 700-2500 nm. In some embodiments, the filter layer is a unidirectional light-transmitting layer.

[0013] In some embodiments, the filter layer is a filter film layer disposed on the substrate layer, and the filter film layer can be disposed on the outer surface or the inner surface of the substrate layer by film plating means.

[0014] In some embodiments, the filter layer is an optical coating film, and the filter layer and the substrate layer are stacked in sequence along the first direction, or stacked in sequence along a direction opposite to the first direction. The optical coating film can be a soft film or a hard film.

[0015] In some embodiments, the natural light cosmetic cover further comprises a cover layer made of a light-transmitting material, and the cover layer and the substrate layer are stacked in sequence along the first direction. In specific embodiments, the cover layer is made of a transparent material or a microporous light-transmitting material (for example, cloth or gauze).

[0016] In some embodiments, the filter layer is arranged between the cover layer and the substrate layer, and the cover layer, the filter layer, and the substrate layer are stacked in sequence along the first direction. Specifically, the filter layer can be arranged on the outer surface of the substrate layer by coating, or arranged on the inner surface of the cover layer by coating, or the filter layer can be an optical coating film arranged between the cover layer and the substrate layer. When the filter layer is arranged between the substrate layer and the cover layer, the substrate layer serves to improve the comfort of contact with the skin, separates the cover layer and the filter layer from the skin, and can provide support to strengthen the stability of the filter layer. The cover layer can provide support and protection for the substrate layer and the filter layer, and can be decorated with patterns or colors, which do not affect the optical properties of light transmission, light filtering, and light reflection.

[0017] In some embodiments, the filter layer is arranged on the outer surface of the cover layer, and the filter layer, the cover layer, and the substrate layer are stacked in sequence along the first direction. Specifically, the filter layer can be arranged on the outer surface of the cover layer by coating, or the filter layer can be an optical coating film arranged on the outer surface of the cover layer, in which case the substrate layer serves to improve the comfort of contact with the skin, and separates the cover layer and the filter layer from the skin. Alternatively, the filter layer can be arranged on the inner surface of the substrate layer, and the cover layer, the substrate layer, and the filter layer are stacked in sequence along the first direction. Specifically, the filter layer can be arranged on the inner surface of the substrate layer by coating, or the filter layer can be an optical coating film arranged in the substrate layer, in which case the substrate layer can provide support to strengthen the stability of the filter layer. In specific embodiments, the filter layer is usually arranged between the cover layer and the substrate layer to improve the comfort of the substrate layer adhering to the skin and to protect the filter layer.

[0018] In some embodiments, the filter layer can be an integral structure, or a combination of multiple units distributed in different regions, and the wavelength range of the cut-off light of each unit can be the same or different.

[0019] In some embodiments, the light filtering layer comprises one or more specific filter film layers that cut off light waves in specific wave band intervals, so as to cut off the incidence of light waves in the at least one wave band interval, or different wave bands are cut off in different regions.

[0020] In some embodiments, the natural light beauty care mask has a shape of a face mask or a mouth mask for facial use, a neck mask for neck use, a face and neck integrated mask, or a sun visor. Advantages

[0021] Compared with the prior art, the present application has the following advantages:

[0022] The natural light beauty care mask of the present application filters light waves in a targeted manner through the light filtering layer, cuts off the incidence of harmful wave band light, and allows light waves in wave bands that have a beauty care or therapeutic effect on the skin to pass through the natural light beauty care mask and be incident on the user's skin. The light waves in natural light are used to whiten the skin, remove redness, soften the skin, stimulate collagen regeneration, etc. The light waves in sunlight are a full-spectrum light source that contains various wave bands of light that are useful for the skin, such as infrared light above 900 nm and visible light between 500 nm and 700 nm, which have the effects of whitening the skin, removing freckles, stimulating collagen regeneration, removing red blood vessels, promoting blood circulation, etc. Therefore, the natural light beauty care mask of the present application can be used as an outdoor beauty care tool to take advantage of natural sunlight energy for beauty care during travel, which is a new energy-saving beauty care method. At the same time, it saves the user's time for separate beauty care, is very convenient to wear and operate, and reduces the interference with normal travel and activities. It not only solves the problem of sun protection, but also takes into account the beauty care effect, and at the same time, it can achieve the functions of dust prevention, beauty, and the functions of a mouth mask, a face mask, a sun visor, and beauty care.

[0033] Referring to FIGS. 1 and 2, in this embodiment, the natural light cosmetic cover includes a substrate layer 130, a filter layer 120, and a cover layer 110. The substrate layer 130 and the cover layer 110 are made of a light-transmissive material, such as a transparent material or a microporous light-transmissive material, such as cloth or gauze. The filter layer 120 can block light waves of a specific waveband from a first direction. The first direction is the direction of light from the outside world to the natural light cosmetic cover when the natural light cosmetic cover is worn on a user, such as on the face or the neck.

[0034] The filter layer 120 can block light waves of a specific waveband, which includes at least one waveband interval, from being incident, and allow other wavelengths of light waves to be incident. Specifically, the light waves of the specific waveband include light waves of a first waveband, which are preferably selected from the ultraviolet waveband. In another embodiment, the filter layer 120 can block light waves of the first waveband from being incident, and can transmit light waves of a second waveband and reflect light waves of a third waveband. The filter layer 120 can be a unidirectional light-transmissive layer, i.e., it is light-transmissive in the first direction and not light-transmissive in the opposite direction.

[0035] The specific waveband of light waves can include at least one waveband interval, with the ultraviolet light being the preferred waveband, or a double or multiple interval waveband. For example, the specific waveband of light waves is selected from the 280-400 nm waveband, or the 450-550 nm waveband, or the 600-700 nm waveband; for another example, the specific waveband of light waves is selected from the waveband including the 450-550 nm and 600-700 nm two intervals; or the specific waveband of light waves is selected from the waveband including the 500-615 and 900-1800 nm two intervals, for example, the light waves cut off the 900-1800 nm waveband interval, that is, the visible light is blocked and cannot penetrate, while the near-infrared light can penetrate; or a more fine range of intervals is selected, and so on, so that the waveband of light with a cosmetic or therapeutic effect on the skin is allowed to pass through the natural light cosmetic shield and be incident on the user's skin. In a more specific embodiment, the cut-off wavelength of the light filtering layer 120 is 280-400 nm, the transmission wavelength is 400-700 nm, and the reflection wavelength is 700-2500 nm. The selection of the waveband interval and the specific correspondence with the skin cosmetic treatment function belong to the field of cosmetic medicine, and can be selected through the publicly disclosed knowledge of cosmetic medicine to achieve the corresponding cosmetic medical function, for example, cosmetic medical journals or papers, other existing public achievements in cosmetic medicine, etc., so that it can be known which waveband cut-off can prevent the damage of light to the skin, and which waveband passing can allow the light to have a cosmetic effect on the skin.

[0036] In Embodiment One, the light filtering layer 120 is an optical coating film, and the cover layer 110, the light filtering layer 120, and the substrate layer 130 are sequentially stacked along the first direction. The light filtering layer 120 is arranged between the cover layer 110 and the substrate layer 130, and is fixed between the cover layer 110 and the substrate layer 130, so as not to be easily displaced or detached, thereby ensuring the stability and durability of the light filtering effect. The optical coating film can be a soft film or a hard film. In other embodiments, the light filtering layer 120 is a light filtering film arranged on the substrate layer 130, and the light filtering film can be arranged on the outer surface or the inner surface of the substrate layer 130 by coating means.

[0037] The cover layer 110 plays a role in shaping, protection, dust prevention, aesthetics, etc., and can be a transparent material or a microporous light-transmitting material (such as cloth or gauze, etc.), thereby improving the light-transmitting property and comfort of the mask. The material selection takes into account factors such as comfort, light-transmitting property, durability, etc., to ensure comfortable wearing and a good service life. The materials of the substrate layer 130 and the cover layer 110 can be the same or different. In a specific embodiment, the materials of the substrate layer 130 and the cover layer 110 are polycarbonate (PC), which has good light-transmitting property, weather resistance, and comfort.

[0039] The filter layer 120 can be an integral structure or a combination of multiple units distributed in zones, and the cut-off light wave band of each unit can be the same or different. The filter layer 120 includes the superposition of one or more specific filter film layers that cut off specific wave bands of light waves in a specific range, to achieve the cutting off of the incidence of at least one wave band of light waves, or to set different cut-off wave bands in each zone in a distributed manner. For example, different skin treatment needs can be selected in different zones. When the filter layer 120 is a filter film set on the substrate layer 130, it can be achieved by zone plating, for example, different cut-off wave band filter films are plated on the forehead and cheek areas of the face respectively; when the filter layer 120 is an optical film-coated film sheet, a zone film sheet can be clamped between the cover layer 110 and the substrate layer 130 by fitting, or can be set between the cover layer 110 and the substrate layer 130 by adhesion, or can be adhered to the outer surface or inner surface of the cover layer 110, or can be adhered to the outer surface or inner surface of the substrate layer 130, and multiple film sheets can also be adhered or connected together by encapsulation, etc. to facilitate processing and operation, and to reduce manufacturing costs. As shown in Fig. 3, filter coating or filter film sheets 123 are provided on the base of the filter layer 120 in different zones, and the cut-off wave bands of the filter coating or filter film sheets 123 in each zone can be the same or different, and different cut-off wave bands can be set in different zones according to actual needs.

The filter layer 220 can cut off the light waves of a specific waveband incident from a first direction. The first direction is the direction of light incident on the natural light cosmetic mask from the outside when the natural light cosmetic mask is worn on the user's body, such as the face or the neck.

[0041] The filter layer 220 can cut off the light waves of a specific waveband, which includes at least one waveband interval, and allow other wavelengths of light waves to be incident. Specifically, the light waves of the specific waveband include at least the first waveband of light waves, which is preferably selected from the ultraviolet waveband. In another embodiment, the filter layer 220 can cut off the incident light waves of the first waveband, and also transmit the incident light waves of the second waveband and reflect the light waves of the third waveband. The filter layer 220 can be made into a one-way light-transmitting layer, that is, it transmits light along the first direction, but does not transmit light along the opposite direction.

[0042] The filter layer 220 is an optical coating film, and the cover layer 210, the filter layer 220, and the substrate layer 230 are laminated in the first direction. The filter layer 220 is arranged between the cover layer 210 and the substrate layer 230, and is not easily displaced or detached by being fixed between the cover layer 210 and the substrate layer 230, thereby ensuring the stability and durability of the filtering effect. The optical coating film can be a soft film or a hard film. In another embodiment, the filter layer 220 is a filter film arranged on the substrate layer 230, which can be arranged on the outer surface or the inner surface of the substrate layer 230 by coating.

[0045] Please refer to Fig. 6, in the third embodiment, the natural light cosmetic shield is shaped to match the corresponding shape of the sun visor 401, and the natural light cosmetic shield used as the sun visor 401 is hung below the brim 402 to shield the face. The sun visor 401 is as described in the previous embodiments, and also includes a cover layer, a filter layer, and a substrate layer, which have the same structural features and variable forms as the previous embodiments, and will not be repeated here. In addition, in other embodiments, the sun visor 401 and its brim 402 can be provided as components of the natural light cosmetic shield, that is, the sun visor 401 and its brim 402 are also implemented by the natural light cosmetic shield, and the sun visor 401 and its brim 402 can be made together or connected together, and each part can be made of the same material or different materials.

[0046] In other embodiments, the natural light cosmetic shield can also be shaped like a mask or a veil or a hood, or a neck shield for use on the neck, or a suitable shape for use on other parts of the human body, such as a sleeve, etc. The shape of the natural light cosmetic shield is not limited. For easy wearing, the natural light cosmetic shield can be provided with auxiliary structures for wearing, such as ear hanging ropes similar to wearing masks, such as fixing members for fixing to sun visors, such as head ropes for fixing face and neck integrated shields on the face and neck, etc.

[0047] The natural light cosmetic shield of the present application filters light through the filter layer 120, blocks harmful waveband light from entering, and allows light in the waveband that has a cosmetic or therapeutic effect on the skin to pass through the natural light cosmetic shield and enter the user's skin. The natural light cosmetic shield uses the light waves in natural light to whiten the skin, reduce redness, soften the skin, stimulate collagen regeneration, etc. The light waves of sunlight are a full-spectrum light source that contains various wavebands of light that are beneficial to the skin, such as infrared light above 900 nm, visible light between 500-700 nm, which has the effects of whitening the skin, removing freckles, stimulating collagen regeneration, reducing red blood vessels, promoting blood circulation, etc. Therefore, the natural light cosmetic shield of the present application can be used as an outdoor cosmetic tool to take advantage of natural sunlight energy for cosmetic purposes during travel, which is a new energy-saving cosmetic method. It also saves the user's time for individual cosmetic purposes, and is very convenient to wear and operate, reducing the interference with normal travel and activities. It not only solves the problem of sun protection, but also takes into account the cosmetic effect, and at the same time can achieve dustproof, aesthetic functions, and also has the functions of a mask, a face shield, a sun visor, and a cosmetic function.

[0048] In use, the natural light beauty care mask can be worn on the face, allowing natural light to pass through the filter on the natural light beauty care mask and shine on the skin. Specifically, when worn, the substrate layer 130 is in contact with the skin, and the natural light passes through the cover layer 110 and the filter layer 120, and after filtering the light of a specific wavelength, it shines on the skin, using the light waves in the natural light to whiten, remove redness, and stimulate collagen regeneration. By filtering, the light waves in the natural light are used to whiten the skin, which is a non-invasive skin care method. This method uses the filter layer 120 to filter harmful light waves such as ultraviolet light and blue light, while allowing beneficial light waves such as red light and near-infrared light to pass through. These beneficial light waves can promote skin cell metabolism, increase blood circulation, and improve skin texture, thereby achieving the effect of whitening. Specifically, the duration of this process can be adjusted according to individual skin conditions and needs, typically 10-30 minutes, or longer, to achieve the purpose of using natural light for beauty care, while improving the light transmittance and comfort of the mask, and reducing the interference with normal travel and activities. This method mainly uses the light waves in natural light to whiten, remove redness, and stimulate collagen regeneration. This method is not only safe, but also saves time and cost. The method of using natural light for beauty care solves the safety and side effects of traditional beauty care methods to some extent.

[0049] Compared with the prior art, the natural light beauty care mask of the present application improves the effect of natural light beauty care. The effect of existing sunscreen and sun hat tools is often limited and cannot completely filter out harmful light waves, and the safety is improved. The technical solution of the present application filters out harmful light waves such as ultraviolet light by using an optical film, and only allows beneficial light waves such as visible light and near-infrared light to pass through, thereby improving the effect of natural light beauty care. This not only avoids the harm of harmful light waves to the skin, but also promotes skin health using beneficial light waves. Compared with existing sunscreen and sun hat tools, the safety of the present application is higher. The cover layer and the substrate layer are made of light-transmitting materials, which can be transparent materials or microporous light-transmitting materials, thereby improving the light transmittance and comfort of the mask. On the other hand, it reduces the interference with normal travel and activities. The existing method of using natural light for beauty care, such as using special sunscreen or sun hat tools, may affect normal travel and activities. In the technical solution of the present application, the optical film is fixed on the surface and inner layer of the mask, and people can use natural sunlight energy for beauty care during travel, which saves the time of individual beauty care and reduces the interference with normal travel and activities.

[0050] The above merely describes preferred embodiments of the present application, and the protection scope of the present application is not limited thereto, and any equivalent transformation based on the technical solutions of the present application shall fall within the protection scope of the present application.
