Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to a cosmetic composition and its preparation method. Background Technology

[0002] Cosmetics refer to daily chemical industrial products applied to the skin, hair, nails, lips, and other human body surfaces by rubbing, spraying, or other similar methods for the purpose of cleansing, protecting, beautifying, and modifying. In the modern skincare field, cosmetics have evolved from basic cleansing and moisturizing to in-depth functional care. As the body's first line of defense against the external environment, human skin faces severe challenges to its physiological functions under long-term exposure to complex factors such as ultraviolet radiation, environmental pollution, and oxidative stress. On the one hand, ultraviolet radiation activates the activity of tyrosinase in epidermal melanocytes, causing tyrosine to be converted into melanin and migrate to keratinocytes via melanosomes, leading to dull skin tone, age spots, and photoaging damage. Therefore, it is necessary to reduce melanin synthesis by inhibiting tyrosinase activity or blocking melanin metabolic pathways. On the other hand, with age and external stimuli, the activity of dermal fibroblasts declines, leading to the loss of collagen and elastin fibers. Simultaneously, repeated contractions of facial muscles form dynamic wrinkles. Furthermore, transepidermal water loss and chronic inflammation caused by skin barrier damage further exacerbate skin laxity, blurred contours, and deepened wrinkles. Therefore, there is an urgent need for a skincare cosmetic product that combines soothing and repairing, anti-wrinkle and firming, and whitening and spot-fading effects. Through multi-target synergistic action, it can repair the damaged barrier, inhibit inflammatory response, deeply promote collagen regeneration to support facial contours, and block the melanin production chain from the source, thereby meeting consumers' comprehensive skincare needs for maintaining youthful, healthy, and even-toned skin. Summary of the Invention

[0003] The purpose of this invention is to provide a cosmetic composition and its preparation method, which has the advantages of soothing and repairing, anti-wrinkle and firming, and whitening and fading spots. It solves the problem that ultraviolet radiation will activate tyrosinase, leading to skin pigmentation and photoaging damage, and external stimuli and aging will cause collagen loss and barrier damage, which in turn lead to skin laxity and deepening wrinkles.

Example 4 Please see Figure 1 A method for preparing a cosmetic composition, comprising the following steps: S1. Prepare the aqueous solvent and the soothing and repairing agent. Take the remaining aqueous solvent in the formula as the base, add the soothing and repairing agent to the aqueous solvent, and stir thoroughly to disperse it evenly. S2. Add whitening agent and firming and anti-wrinkle agent. After stirring the aqueous system evenly, add the whitening agent and firming and anti-wrinkle agent in sequence, and continue to stir the mixed system to ensure that the various active ingredients are evenly distributed. S3. Add the barrier repair complex. Add the pre-prepared barrier repair complex to the above mixture. Furthermore, after all the components in S3 have been added, continue stirring the mixture for 8-10 minutes to ensure that each component is microscopically uniform and stable. Then, let the mixed cosmetic composition stand to remove the air bubbles generated during stirring, making the product texture more delicate and stable. Furthermore, the semi-finished product after standing is subjected to physicochemical and microbiological tests. After confirming that all indicators meet the standards, it is filled into sterile packaging containers to complete the preparation. By adopting a step-by-step addition strategy, the soothing and repairing agent is first fully dispersed in an aqueous solvent, and then the whitening agent, firming and anti-wrinkle agent and barrier repair complex are added in sequence. This orderly mixing method can effectively avoid physicochemical reactions or aggregation and precipitation of different active ingredients when they come into direct contact at high concentrations, thereby ensuring that various trace and macro-level active ingredients are evenly distributed and highly stable at the microscopic level in the system. After adding the complex, continuous stirring for 8-10 minutes, followed by a settling and degassing process, not only further promotes the molecular-level fusion between the components, but also effectively eliminates the air bubbles introduced by mechanical stirring, significantly improving the texture, gloss, and physical stability of the final product during long-term storage. Finally, by combining physicochemical indicators and microbiological testing with aseptic filling processes, the risk of contamination is eliminated at the source of the process, and the biological activity of heat-sensitive and bioactive ingredients in the formula is preserved to the greatest extent, ensuring that the final product has excellent gentleness, safety and multi-functional maintenance.
