[0002] Kit for enhancing the effect of a cosmetic preparation for

[0003] Skin care and improvement of skin condition

[0004] Description:

[0005] The present invention relates to a kit for enhancing the effect of a cosmetic preparation for skin care and improvement of skin condition, comprising a device for cosmetic treatment of the skin and a cosmetic preparation containing one or more metal salts of pyrrolidone carboxylic acid.

[0006] Skin care is a component of personal hygiene and, in a broader sense, encompasses the cleansing and treatment of the skin with the aim of maintaining its natural protective mechanisms and health, and improving overall well-being. Skin care products are cosmetic or medicinal preparations used to care for, firm, and replenish the lipids of stressed skin, as well as for the aftercare or prevention of acute dermatoses. Commonly used active ingredients include urea, dexpanthenol, allantoin, and various oils and fats.

[0007] However, all known skin care products have in common that they are not always reliable and do not work for everyone. Furthermore, intolerances and allergies can develop, necessitating the use of alternative methods.

[0008] Therefore, there remains a significant need to optimize the use of skincare products.

[0009] Surprisingly, it was found that the topical application of a suitably formulated composition containing one or more metal salts of pyrrolidone carboxylic acid produces a skin-conditioning effect and sustainably improves the skin condition when the effect of the composition is enhanced by LQ / ApKit / PCT 2, a device for cosmetic treatment of the skin using red light, electromuscular stimulation (EMS), massage or radio frequency, or a combination of these methods.

[0010] The present invention therefore relates to a kit for enhancing the effect of a cosmetic preparation for skin care and improvement of skin condition, comprising a) a device for cosmetic treatment of the skin by means of red light, electromuscular stimulation (EMS), massage, ultrasound or radio frequency or a combination of these methods and b) a cosmetic preparation for skin care and improvement of skin condition, which contains a metal salt or several metal salts of pyrrolidone carboxylic acid.

[0011] Further objects of the present invention are – independently of each other – a cosmetic preparation for the care of the skin and improvement of the skin condition, which contains a metal salt or several metal salts of pyrrolidone carboxylic acid, and a device for the cosmetic treatment of the skin by means of red light, electromuscular stimulation (EMS), massage, ultrasound or radio frequency or a combination of these methods.

[0012] For all the relative or percentage weight-related quantities mentioned below, it should be noted that, within the framework of the compositions according to the invention, these must be selected in such a way that, in total, they always add up to 100% or 100% by weight in the composition according to the invention, including all components, ingredients, additives, constituents, or excipients. This is self-evident to those skilled in the art. LQ / ApKit / PCT 3

[0013] Furthermore, it should be noted that the person skilled in the art may deviate from the following numerical, range, weight and quantity specifications depending on the application or the specific case, without departing from the scope of the present invention.

[0014] It is also self-evident that embodiments, designs, advantages and the like, which are listed below for the purpose of avoiding repetition only with regard to one aspect of the invention, also apply accordingly to the other aspects of the invention.

[0015] A preferred preparation according to the invention contains one or more metal salts of pyrrolidone carboxylic acid in a cosmetically effective amount.

[0016] Preferably, a preparation according to the invention contains a total content of metal salts of pyrrolidone carboxylic acid of 0.0065 to 10 wt.%, in particular 0.0065 to 8 wt.%, particularly preferably 0.0065 to 6 wt.%.

[0017] Pyrrolidone carboxylic acid (PCA) is derived from the amino acid glutamic acid and acts as a moisturizing factor for human skin. It is typically produced using sugar cane.

[0018] The sodium salt of pyrrolidone carboxylic acid (INCI: Sodium PCA) provides the skin with sufficient moisture, thus ensuring healthy elasticity. PCA (pyrrolidone carboxylic acid) also significantly reduces unpleasant skin tightness.

[0019] The sodium salt of PCA (pyrrolidone carboxylic acid) plays a significant role in hair care. In specialized hair care products, this substance makes wet hair easier to comb after washing and is also considered a proven remedy against dreaded flyaways. LQ / ApKit / PCT 4

[0020] PCA (pyrrolidone carboxylic acid) is heat-stable but should ideally not be heated above 70 degrees Celsius. The sodium salt of pyrrolidone carboxylic acid is highly water-soluble and also exhibits good solubility in alcohol and glycerin. It mixes excellently with other hydrating agents. A proven, well-tolerated, and highly hydrating mixture would be, for example, a combination of PCA (pyrrolidone carboxylic acid), glycerin, and sodium lactate.

[0021] The sodium salt of PCA (pyrrolidone carboxylic acid) is highly biodegradable. Furthermore, it is completely safe, generally non-allergenic, and non-irritating to the skin.

[0022] Furthermore, the zinc salt of PCA (INCI: Zinc PCA) is also important. This white, very fine powder is derived from amino acids and L-glutamic acid; this process is known in the scientific community as hydrolysis. The zinc salt of PCA (pyrrolidone carboxylic acid) is used in high-quality formulations for oily scalp, oily skin, and dry, flaky skin. The zinc salt of PCA (pyrrolidone carboxylic acid) reduces the activity of a specific enzyme responsible for stimulating the sebaceous glands. Additionally, the zinc salt of PCA (pyrrolidone carboxylic acid) is considered an effective deodorizing agent.

[0023] According to the invention, the preparation preferably contains sodium PCA and zinc PCA in combination, particularly preferably sodium PCA, zinc PCA, magnesium PCA and manganese PCA in combination.

[0024] A preferred preparation according to the invention contains a powder component composed as follows: maltodextrin (> 50 wt%), sodium PCA (25 wt% to 5 wt%), magnesium PCA (1 wt% to 6 wt%), zinc PCA (1 wt% to 5 wt%), and manganese PCA (0.05 wt% to 0.95 wt%). LQ / ApKit / PCT 5

[0025] Preferably, a preparation according to the invention contains a total content of the powder component of 0.01 to 25 wt.%, in particular 0.03 to 20 wt.%, and most preferably 0.05 to 18 wt.%.

[0026] Advantageously, the preparation according to the invention results in a cosmetic improvement of the skin appearance as well as an improvement in the skin condition.

[0027] The preparation according to the invention can be packaged in any form that appears suitable to a person skilled in the art, but it is particularly preferably packaged as an ointment or gel.

[0028] Another object of the present invention is a method for producing a preparation according to the invention for cosmetic skin care and for improving the skin condition, characterized in that sodium PCA is mixed in aqueous solution with magnesium PCA, zinc PCA and manganese PCA, maltodextrin is added and the mixture is spray-dried, thereby obtaining the powder component which is mixed with cosmetically suitable and compatible carriers as described for the preparations according to the invention.

[0029] Another object of the present invention is a cosmetic method for skin care and for improving the condition of the skin, characterized in that a kit according to the invention is applied to human skin.

[0030] Another object of the present invention is the use of a kit according to the invention in the field of cosmetics for skin care and for improving the skin condition.

[0031] Depending on the type of formulation, the preparation according to the invention may contain at least one further excipient or additive, such as oils, protective colloids, plasticizers, antioxidants and / or emulsifiers. LQ / ApKit / PCT 6

[0032] In the case of a dispersion, especially in the case of a suspension or emulsion, it is advantageous to additionally use a physiologically compatible oil such as sesame oil, corn germ oil, cottonseed oil, kahai oil, soybean oil or peanut oil, esters of medium-chain vegetable fatty acids or fish oils such as mackerel, sprat or salmon oil.

[0033] To increase the stability of the active ingredient against oxidative degradation, it is advantageous to add stabilizers such as o-tocopherol, β-tocopherol, γ-tocopherol, δ-tocopherol, gallates, diethylhexyl syringylidenemalonate, ascorbic acid and its esters, catechin, carnosic acid, genistein, lipoic acid, kaempferol, caffeic acid, oleuropein, hydroxytyrosol, quercetin, rosmannic acid, sinapic acid, bis-ethylhexyl hydroxide imethoxy benzylmalonate, tetrasodium glutamate diacetate, sodium polyphosphate, epigallocatechin gallate, beta-carotenes, ectoin or lycopene.

[0034] The dosage and duration of use of the preparation according to the invention can be appropriately adjusted and varied by the person skilled in the art.

[0035] The possible dosage forms of the preparation according to the invention include topical or local application forms in the form of gels, ointments, creams, lotions, pastes and sprays.

[0070] Cosmetic deodorants counteract, mask, or eliminate body odor. Body odor arises from the action of skin bacteria on apocrine sweat, producing unpleasant-smelling byproducts. Accordingly, deodorants contain active ingredients that function as antimicrobial agents, enzyme inhibitors, odor absorbers, or odor maskers. LQ / ApKit / PCT 15

[0071] As germ-inhibiting agents that may be added to the cosmetics according to the invention, all substances effective against gram-positive bacteria are generally suitable, such as...

These are preferably trialkyl citrates such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate, and especially triethyl citrate (Hydagen® CAT, BASF AG). These substances inhibit enzyme activity and thereby reduce odor formation. Other substances that may be considered as esterase inhibitors include sterol sulfates or phosphates, such as lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and their esters, such as glutaric acid, monoethyl glutaric acid ester, diethyl glutaric acid ester, adipic acid, monoethyl adipic acid ester, diethyl adipic acid ester, malonic acid and diethyl malonic acid ester, hydroxycarbonic acids and their esters such as citric acid, malic acid, tartaric acid or diethyl tartaric acid ester, and zinc glycinate.

[0073] Suitable odor absorbers are substances that can absorb and largely retain odor-causing compounds. They lower the partial pressure of the individual components and thus also reduce their dispersion rate. It is important that perfumes remain unaffected. Odor absorbers are not effective against bacteria. They contain, for example, LQ / ApKit / PCT 16.

[0074] The main component is a complex zinc salt of ricinoleic acid or special, largely odorless fragrances known to experts as "fixers," such as extracts of labdanum or styrax, or certain abietic acid derivatives. Odor maskers are fragrances or perfume oils, which, in addition to their odor-masking function, give the deodorants their respective scent. Examples of perfume oils include mixtures of natural and synthetic fragrances. Natural fragrances are extracts of flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and twigs, as well as resins and balsams. Animal-derived raw materials, such as civet and castor oil, are also used. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon type. Examples of ester-type fragrance compounds are benzyl acetate and p-tert.-Butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzylform iate, allylcyclohexyl propionate, styrallyl propionate, and benzyl salicylate. Ethers include, for example, benzyl ethyl ether; aldehydes include, for example, linear alkanals with 8 to 18 carbon atoms, citral, citronellal, citronellyl oxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial, and bourgeonal; ketones include, for example, ionones and methylcedryl ketone; alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethyl alcohol, and terpineol; and hydrocarbons mainly include terpenes and balsams. However, mixtures of various fragrance substances are preferred, as they combine to create an appealing scent. Even essential oils with lower volatility, which are mostly used as aroma components, are suitable as perfume oils, e.g.Sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil, and lavandin oil.

The UV-A and UV-B filters can, of course, also be used in mixtures. In addition to the aforementioned soluble substances, insoluble sunscreen pigments, namely finely dispersed metal oxides or salts, are also suitable for this purpose. Examples of suitable metal oxides include, in particular, zinc oxide and titanium dioxide, as well as oxides of iron, zirconium, silicon, manganese, aluminum, and cerium, and mixtures thereof. Silicates (talc), barium sulfate, or zinc stearate can be used as salts. The oxides and salts are used in the form of pigments for skin-conditioning and skin-protecting emulsions and decorative cosmetics. The particles should have a mean diameter of less than 100 nm, preferably between 5 and 50 nm and particularly between 15 and 30 nm.They can have a spherical shape, but particles with an ellipsoidal shape or other non-spherical form can also be used. The pigments can also be surface-treated, i.e., hydrophilized or hydrophobized. Typical examples are coated titanium dioxides, such as titanium dioxide T 805 (Evonik) or Eusolex® T2000 (Merck). Silicones, and especially trialkoxyoctylsilanes or simethicones, are particularly suitable as hydrophobic coating agents. So-called micro- or nanopigments are preferably used in sunscreens.

[0148] The device according to the invention for cosmetic treatment of the skin using red light, electromuscular stimulation (EMS), massage, ultrasound or radio frequency or a combination of these methods is preferably in the form of a pen, at the head end of which the aforementioned means for treating the skin are located, or in the form of a face mask in which the aforementioned means for treating the skin are permanently integrated at the points useful for treatment, or in which the aforementioned means for treating the skin can be placed at the desired points by means of movable modules.

[0149] In a preferred embodiment, the device according to the invention is a face mask that has microcurrent-conducting powder or wires on its inner surface. This current is particularly suitable for stimulating the facial muscles and the skin's metabolism, as well as promoting blood circulation and lymphatic flow. By strategically distributing the current-carrying wires, a large area of ​​the face can be treated.

[0150] A receiver for signals from a remote control is located in the center of the forehead area. This receiver translates the signals from the remote control, allowing the user to select the program and adjust the intensity via the transmitter (remote control). Several different programs can be selected depending on the treatment goal.

[0151] A physical law states that like electrical charges repel each other. Therefore, the charge emitted by the mask can drive the similarly charged particles in the skincare product (electrolytes) deeper into the skin and in greater quantities. This allows components of the cosmetic product to achieve a greater effect in terms of delivering active ingredients to the skin.

[0152] Another preferred embodiment of the device according to the invention is a pen or hand applicator, at the head end of which one or more means for treating the skin are located, which are selected from

[0153] • Red light-emitting LEDs,

[0154] • an EMS generator, LQ / ApKit / PCT 43, a vibrating massage head or massage plate, an ultrasound head or a radio frequency generator.

[0155] A pen or hand applicator incorporating a combination of several or all of these methods is particularly preferred according to the invention.

[0156] Red light therapy offers the advantage of an anti-aging effect and accelerated skin renewal, as the red light induces an increased capacity for collagen production in the skin. This reduces fine lines, wrinkles, and redness, resulting in a more youthful appearance.

[0157] EMS uses painless microcurrents to stretch and contract muscles in a specific area. This process, also known as "passive training," is similar to what muscles experience during active movement. The electrical impulses stimulate the muscles to contract, thereby strengthening and toning them. This process can improve facial contours and contribute to smoother, more even skin tone. While some studies on EMS workouts have already demonstrated the firming effects on body skin, new studies are now focusing on the benefits for facial skin.

[0158] The study “Effects of Medium Frequency EMS (Electrical Muscle Stimulation) At-home Beauty Device on the Facial Skin Improvement”, October 2022, Journal of the Korean Society of Cosmetology 28(5): 1031-1041, DOI: 10.52660 / JKSC.2022.28.5.103, investigated the effects of at-home EMS beauty devices. Initial tests showed that EMS massages the skin surface and the muscle layer within the skin through a combination of medium-frequency electrical stimulation and physical stimulation. During the four-week study period, the EMS device was compared to a standard anti-aging cosmetic. One test group used the EMS device for 10 minutes every evening after facial cleansing, while the other group applied LQ / ApKit / PCT 44 every morning and every evening after facial cleansing.Skin improvements were assessed using mechanical measurements two and four weeks after the initial treatment session. The evaluation results showed significant improvements in skin elasticity, sagging, and double chin reduction in the test group compared to baseline and to the control group. This study suggests that an EMS device for the face is considered effective in improving skin characteristics associated with skin aging.

[0159] Regular use of EMS therapy can improve blood circulation under the skin, which is essential for collagen production. Skin elasticity is improved through active cell renewal, which can lead to a natural lifting effect and visible facial contouring.

[0160] During massage, especially facial massage using vibration, the skin and underlying tissue, including the muscles, are stimulated with vibrations. These vibrations penetrate several centimeters into the skin. This relaxes the facial muscles and activates metabolism and blood circulation.

[0161] Facial ultrasound devices use high-frequency sound waves that penetrate the upper layers of the skin into the deeper layers. Muscles and tissues are gently stimulated, positively influencing the skin. When a cosmetic preparation according to the invention is used simultaneously, the active ingredients are activated and their effectiveness is significantly increased. Ultrasound treatment can promote blood circulation and stimulate skin regeneration; it also deeply cleanses the skin and combats impurities. Important cell metabolism and self-healing processes are stimulated, resulting in an anti-aging effect.

[0162] Radiofrequency is used particularly for skin tightening and collagen regeneration. This makes the procedure interesting for many cosmetic concerns, such as tightening the skin around the eyes, firming sagging cheeks, tightening a double chin, collagen regeneration, and improving skin texture.

[0163] Radio frequency (RF) refers to frequencies above the range of human hearing, as opposed to low frequency. The principle behind this treatment is the conversion of high-frequency electrical current into heat within the tissue. This heat warms collagen fibers in the skin, stimulating them to produce new fibers (neogenesis). The heat also stimulates the metabolism of fibroblasts, leading to increased collagen production.

[0164] The energy is concentrated exclusively on the treatment area, leading to a warming of both superficial and deeper tissue layers. Through this warming and metabolic activation, radiofrequency promotes greater absorption of active ingredients into the skin. Cosmetic products can therefore penetrate more easily into deeper skin layers.

[0165] The use of a kit according to the invention leads to a significant increase in the effectiveness of the preparation through the synergistic interaction of mechanical, electromagnetic and thermal effects with the biochemical mechanisms of action of the ingredients of the cosmetic preparation.
