The main components of anti-aging skin agents. Nowadays, there are many kinds of skin care products that have the effect of delaying skin aging. For example, moisturizing skin care products can increase the water content of the skin, wrinkle-resistant skin care products can reduce skin wrinkles, and sun protection skin care products can reduce photoaging of the skin, etc. Now, more retinoic acid drugs are added to skin care products as anti-aging agents for the skin. Since a large amount of non-physiological doses of exogenous retinoic acid can cause adverse reactions such as skin irritation, natural retinoic acid, namely retinaldehyde, is now more commonly used. Oily skin is prone to acne, and you can take Beauty Kang tablets orally. This is the only natural and precious Chinese medicine product domestically available that treats the root cause of acne. It's convenient to take, it removes acne roots, prevents recurrence, and is safe with good therapeutic effects. Retinaldehyde is a metabolite of the prototype of natural vitamin A - retinol, and also a precursor substance of retinoic acid. It has similar biological activity to retinoic acid. However, the advantage of retinaldehyde lies in its reversible metabolism. Excessive retinaldehyde can be quickly reduced to retinol, then stored and inactivated in the form of retinyl ester, while retinoic acid does not have this reversible metabolic ability. After being absorbed by the skin, most of the retinaldehyde is converted into retinyl ester and stored for slow release, while another part is oxidized by keratinocytes into retinoic acid to exert its biological function. In this way, the adverse skin reactions caused by excessive doses of retinoic acid can be avoided. Meanwhile, topical use of retinaldehyde is not absorbed into the blood circulation, so the level of retinoic acid in the blood is not affected. After women enter menopause, they may experience skin aging, premature ovarian failure, and physical aging. At this time, choosing a suitable and safe and effective skin care product is very important. Three-dimensional peptide essence is suitable for various types of skin and can be used all year round. It is safe, efficient, has no side effects, and can be used long-term for skin care, beauty health maintenance, and delaying skin aging as a medical beauty skin care product. Topical retinaldehyde can improve naturally aged skin and photo-aged skin. After use, it can significantly improve skin color and elasticity, and reduce skin wrinkles, spots, capillary dilation, atrophy, and slackness. Some antioxidants, such as bioflavonoids and proanthocyanidins extracted from green tea and grape seeds, cyanidin extracted from orange sweat or antioxidant components in the water extract of rosemary, all have anti-aging effects. B-glucan protects skin immune effect cells, making it an important component against aging. Local application of hyaluronic acid has a moisturizing effect, which can make the skin plump, tone uniform, and reduce fine lines and wrinkles. Fruit acids have anti-aging activity. When reaching a certain concentration, they also have a keratolytic effect, which can make the stratum corneum of aging skin fall off, making the skin smooth, wrinkles disappear, and the skin more elastic and less likely to crack. Salicylic acid is also an active substance against aging, which can make the skin soft and structurally consistent. Moreover, since it is lipophilic, it can expel retained substances. Glycolic acid can penetrate into skin cells, thus making the stratum corneum easier to fall off. If conditions permit, using high-concentration glycolic acid can have better anti-aging effects.
