Skin aging is a complex physiological process, which is affected by a variety of internal and external factors, such as aging, ultraviolet radiation, environmental pollution, bad living habits, etc. These factors can lead to the loss of collagen in the skin, the breakage of elastic fibers, the accumulation of free radicals and the slowing down of cell metabolism, resulting in wrinkles, sagging, dullness and other signs of aging. Traditional anti-aging skin care products often rely on a single active ingredient, such as vitamin C, E, etc., but the effect is limited and not long-lasting. In recent years, with the development of biotechnology, ingredients such as retinol, peptide complexes, ceramides, astaxanthin and resveratrol have emerged. It has attracted much attention due to its significant anti-aging effect. Although retinol has a strong ability to promote collagen production and cell renewal, it has certain limitations in application due to its poor stability and strong irritation. As an emerging anti-aging ingredient, polypeptide complexes have targeted mechanisms of action, but the research on the synergistic effects of different types of polypeptides still needs to be deepened. Ceramide is essential for maintaining the skin barrier function, but its effective utilization and stability in skin care compositions need to be optimized. Astaxanthin has outstanding antioxidant properties, but its stability and solubility are difficult problems in application. Resveratrol performs well in inhibiting melanin formation, but how to improve its penetration and bioavailability in the skin still needs to be explored.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] The present invention provides the following technical solutions:

[0024] A skin care composition with anti-aging effects, comprising the following components in parts by weight: [retinol] [5] parts, [polypeptide complex] [8] parts, [ceramide] [6] parts, [astaxanthin] [4] parts, and [resveratrol] [3] parts.

[0025] In a specific embodiment of the present invention, retinol can stimulate the production of collagen, improve the structure of the skin from deep layers, reduce the appearance of fine lines and wrinkles, and make the skin firmer and more elastic. The tripeptide-1, hexapeptide-9 and tetrapeptide-7 in the polypeptide complex work together to act on skin cells in a targeted manner, which can not only activate the synthesis of collagen, but also reduce wrinkles caused by muscle contraction, while reducing inflammation and improving the overall health of the skin. Ceramide can enhance the barrier function of the skin, effectively lock in moisture and nutrients, prevent the invasion of external harmful substances, and provide a stable internal environment for the skin. Astaxanthin, as a powerful antioxidant, can scavenge free radicals, reduce the damage of oxidative stress to the skin, and prevent problems related to skin aging, such as dullness and sagging. Resveratrol can inhibit the formation of melanin, brighten the skin tone, improve dull skin, and make the skin glow with natural luster and vitality. These ingredients cooperate with each other and work together to resist skin aging from multiple aspects, bringing comprehensive and significant anti-aging effects to users.

[0026] Specifically, the purity of [retinol] is [98%] and it is processed using microencapsulation technology to improve the stability of retinol and reduce its irritation. This microencapsulation technology enables retinol to be slowly released into the skin, exerting a more lasting anti-aging effect.

[0027] In this embodiment: high-purity retinol ensures its strong activity and efficacy, and can more effectively promote the production of collagen and cell renewal, thereby more effectively reducing wrinkles and sagging. The microencapsulation technology has many advantages. First, it significantly improves the stability of retinol, making it less likely to decompose and deteriorate during storage and use, thereby ensuring the long-term effectiveness of the product. Secondly, this technology reduces the irritation of retinol and reduces skin discomfort that may occur during use, such as redness, swelling, itching, etc., so that more people with different skin types can benefit from the anti-aging effect of retinol. Moreover, microencapsulation can slowly release retinol in the skin, exert a more lasting effect, avoid the side effects that may be caused by a one-time large-scale release, and at the same time prolong the duration of its anti-aging effect. In this way, users can get a gentler, more lasting and more effective anti-aging skin care experience.

[0028] Specifically, the [peptide complex] is composed of [tripeptide-1], [hexapeptide-9] and [tetrapeptide-7] in a [1:2:1] ratio. Tripeptide-1 can activate collagen synthesis, hexapeptide-9 can reduce wrinkles caused by muscle contraction, and tetrapeptide-7 helps reduce inflammation, working together to improve skin firmness and smoothness.

[0029] In this embodiment: tripeptide-1, as an activator of collagen synthesis, can stimulate the skin to produce more collagen, increase the firmness and elasticity of the skin, and fundamentally improve the aging state of the skin. Hexapeptide-9 reduces wrinkles caused by muscle contraction and makes the skin surface smoother, especially for dynamic wrinkles such as expression lines. It has an excellent improvement effect. Tetrapeptide-7 helps to reduce inflammation, create a healthy internal environment for the skin, and promote other anti-aging ingredients to play a better role. These three polypeptides work synergistically in a ratio of 1:2:1 to form a comprehensive and efficient anti-aging mechanism. They not only work on different aging problems respectively, but also enhance each other's effects and jointly improve the firmness and smoothness of the skin. This synergistic effect can improve the signs of skin aging more quickly and significantly, restore the skin to a youthful state, and rejuvenate and glow.

[0030] Specifically, a method for preparing a skin care composition with anti-aging effects comprises the following steps:

[0031] Step 1: Mix [retinol], [ceramide] and [astaxanthin] in proportion, stir at [45°C] for [30 minutes], at a stirring speed of [250 rpm], using a [high-precision electric stirrer] to ensure that the mixture is fully uniform.

[0032] Step 2: Add [polypeptide complex] and [resveratrol] to the above mixture, continue stirring at [55°C] for [20 minutes], with a stirring speed of [180 rpm], and use [inert gas protection] to prevent the active ingredients from being oxidized.

[0033] Step 3: Cool down to [30℃], add appropriate amount of [non-irritating preservatives] and [natural flavors], and stir well to ensure the safety of the product and the user experience.

[0034] In this embodiment: in step 1, retinol, ceramide and astaxanthin are stirred at 45°C for 30 minutes according to the proportion, and a high-precision electric stirrer at 250 rpm is used to ensure that these ingredients are fully and evenly mixed. The appropriate temperature helps to improve the solubility and compatibility of the ingredients, so that they can interact with each other better. The high-precision electric stirrer can ensure the uniformity and efficiency of stirring, avoid the situation of local uneven ingredients, thereby ensuring that the product can exert a stable and consistent effect when used. In step 2, the polypeptide complex and resveratrol are added to the mixture, and stirring is continued at 55°C for 20 minutes, while inert gas protection is used. This process can make the newly added ingredients fully integrated into the mixture, and the inert gas protection effectively prevents the active ingredients from being oxidized at high temperature, and retains their activity and efficacy to the greatest extent. Through such precisely controlled preparation steps, it can ensure that each ingredient is evenly distributed in the mixture, and the activity is fully retained, thereby providing a strong guarantee for the high quality and significant anti-aging effect of the product.

[0035] Specifically, the stirring device used in step one is an [electric stirrer], and the shape of its stirring blade is [spiral], which can more effectively drive the flow of the mixture and achieve uniform mixing.

[0036] In the present embodiment: the use of an electric stirrer can provide stable and continuous stirring power, ensuring that the mixture always remains in a uniform state during the stirring process. Compared with manual stirring or other simple stirring methods, the electric stirrer can better meet the needs of large-scale production and ensure the consistency of product quality. The shape design of the spiral stirring blade has unique advantages. It can more effectively drive the flow of the mixture, so that the ingredients located at different positions in the stirring container can fully participate in the mixing process. This design reduces the occurrence of stirring dead corners and ensures that the mixture reaches a highly uniform state in a short time. By using this specific stirring equipment and blade shape, production efficiency can be improved and production costs can be reduced. At the same time, the uniform distribution of the ingredients in the skin care composition is ensured, so that the product can provide consumers with stable and reliable anti-aging effects when used.

[0037] Specifically, the temperature control in step 2 is achieved by an advanced PID temperature controller with an accuracy of ±0.5°C. The temperature controller can monitor and adjust the temperature of the reaction system in real time to ensure the stability and accuracy of the reaction conditions.

[0038] In this embodiment: an advanced PID temperature controller is used to achieve precise control of the temperature of the reaction system with an accuracy of ±0.5°C. This high-precision temperature control is crucial for the preparation of the skin care composition. First, it ensures that the reaction is carried out within the set temperature range, so that the various components can react and interact with each other under the optimal temperature conditions, thereby giving full play to their efficacy. Secondly, stable and accurate temperature control helps to reduce the impact of temperature fluctuations on active ingredients, avoids inactivation or deterioration of ingredients due to excessively high or low temperatures, and retains the activity and stability of each ingredient to the greatest extent. Furthermore, precise temperature control can improve the repeatability and consistency of the preparation process, and ensure that the quality of each batch of products is stable and reliable. Through this advanced temperature control technology, high-quality, high-performance anti-aging skin care compositions can be produced to provide consumers with a more effective skin care experience.

[0039] Specifically, the skin care composition can significantly improve signs of skin aging, such as reducing wrinkles, improving firmness, and increasing skin gloss and elasticity, thereby restoring the skin to a youthful state.

[0040] In this embodiment: the composition can deeply improve the signs of skin aging and bring many positive changes to the user. First, in terms of reducing wrinkles, by stimulating the production of collagen and enhancing the vitality of skin cells, the appearance of fine lines and deep lines is effectively reduced, making the skin surface smoother and tighter. In terms of improving firmness, the skin's own repair mechanism is activated, and the skin's elastic fibers are enhanced, thereby improving the skin's firmness and shaping a clearer facial contour. In terms of increasing the skin's glossiness, by removing free radicals, inhibiting melanin formation, and promoting cell metabolism, the skin can radiate a natural and healthy luster and present a bright and transparent state. In terms of enhancing skin elasticity, the skin is prompted to produce more elastin, restore the skin's elasticity and toughness, and reduce sagging and sagging. These beneficial effects enable the skin to return to a youthful state, enhance the user's self-confidence and appearance, and meet people's pursuit of keeping skin healthy and beautiful.

[0041] Specifically, skin care products are one of the following: cream, lotion, essence and mask. In cream, it can provide deep nourishment and long-lasting moisturizing; in lotion, it can keep the skin fresh while providing anti-aging care; in essence, it can efficiently penetrate the skin to exert its effect; in mask, it can intensively supplement nutrition and repair the skin.

[0042] In this embodiment: when applied in a face cream, since the face cream usually has a high degree of moisturizing and nutrients, it can provide deep nourishment and long-lasting moisturizing for the skin. This deep nourishment helps to replenish the moisture and nutrients required by the skin, improve fine lines and roughness caused by dryness, and at the same time, long-lasting moisturizing can keep the skin moisturized for a long time, enhance the barrier function of the skin, and further delay the process of skin aging. When applied in a lotion, the texture of the lotion is relatively light and thin, which can keep the skin refreshed while obtaining anti-aging care. This is an ideal choice for consumers who want to avoid greasy feeling in daily care but are eager to prevent and improve skin aging problems. When used in essence, the high concentration and efficient penetration characteristics of the essence enable the skin care composition to act on skin cells more quickly and deeply, focusing on solving key problems of skin aging, such as deep wrinkles, collagen loss, etc., providing more significant and immediate effects. When used in facial masks, the facial masks can provide intensive nutrition and repair ingredients to the skin in a short period of time, so that the efficacy of the skin care composition can be quickly exerted, bringing immediate and visible significant effects, such as brightening skin tone, firming skin, etc. Through reasonable application in different skin care products, it meets the anti-aging care needs of consumers in different scenarios and skin types, and provides diversified and personalized skin care solutions.

[0043] Specifically, the amount of the skin care composition added to the cream is [5%-8%], the amount added to the lotion is [4%-6%], the amount added to the essence is [8%-10%], and the amount added to the mask is [3%-5%]. According to the texture and usage of different skin care products, the amount of addition is reasonably adjusted to achieve the best anti-aging effect while taking into account the stability and safety of the product.

[0044] In this embodiment: in the face cream, the addition amount of 5%-8% can give full play to its nourishing and anti-aging effects. The higher addition amount ensures that the face cream can provide sufficient nutrition and active ingredients for the skin, deeply improve the skin's dryness, wrinkles and other problems, and achieve long-lasting moisturizing and repairing effects. It is especially suitable for dry and severely aged skin. In the lotion, the addition amount of 4%-6% can not only meet the anti-aging needs, but also maintain the refreshing texture of the lotion. This ratio allows the lotion to provide daily care while not bringing too much burden to the skin. It is suitable for all skin types, especially oily and combination skin, and prevents the appearance of signs of aging while maintaining skin health. In the essence, the higher addition amount of 8%-10% can ensure efficient penetration and rapid action. The special formula of the essence The formula and texture can promote the active ingredients to quickly penetrate into the bottom layer of the skin. The high concentration of addition enables the skin care composition to focus on solving deep skin problems, such as enhancing collagen synthesis, repairing damaged cells, etc., bringing significant improvement effects to the skin. In the facial mask, 3%-5% of the addition amount can provide concentrated nutrition and repair for the skin in a short time. The frequency of use of the facial mask is relatively low, but through the appropriate addition amount, a large amount of effective ingredients can be injected into the skin in a short time, producing immediate visible effects, such as brightening skin tone, firming skin, etc., to meet consumers' needs for rapid improvement of skin condition. Through such reasonable and precise adjustment of the addition amount, the advantages of the skin care composition in different skin care products can be fully utilized to provide consumers with different skin types and needs with the most optimized anti-aging care solutions.
