What is Acetyl Tetrapeptide-9?

Acetyl Tetrapeptide-9 is a widely used raw material in skin care products. Its CAS number is 928006-50-2, and its purity is very high, exceeding 95%. This synthetic small molecule protein can stimulate the production of a substance called lumicon and collagen in the skin through special biological effects, so that the skin can become better. Its chemical formula is C22H33N7O9, and its molecular weight is about 539.54. Its structure is N-Ac-Gln-Asp-Val-His-OH, which allows it to bind to certain specific points on skin cells with great precision, and then trigger a series of biological reactions. Acetyl Tetrapeptide-9 can be well dissolved in water, so it can be directly added to the aqueous solution of cosmetics at a temperature not exceeding 40°C. Because it is rich in cosmetic raw materials, many high-end skin care products like to use Acetyl Tetrapeptide-9 as their core ingredient.

Functions and Applications

1. Anti-aging and anti-wrinkle raw materials: Acetyl tetrapeptide-9 can activate a substance in the skin called lumicon, which can help collagen to be better synthesized and fixed, forming a strong fiber network and maintaining the stability of the skin structure. Doing so can make the skin firmer and softer and resist the signs of aging. Therefore, it can also be used in facial care products, especially anti-aging products. It can be used as a core ingredient in skin care products such as essences, lotions, and creams to provide all-round anti-aging protection for the skin.
2. Promote collagen production: It can also promote the production of an important protein, type I collagen, which is the key to skin elasticity and firmness. It will make the skin firmer, more elastic, and look younger. It can be used in eye care products to improve the firmness and elasticity of the skin around the eyes, fade fine lines and dark circles, and make the skin around the eyes brighter and more energetic.
3. Anti-wrinkle raw materials: It not only promotes the production of collagen, but also blocks some signals that cause muscle contraction, allowing facial muscles to relax. This can help reduce dynamic lines, static lines and fine lines, making the skin surface smoother. It can be applied to the neck and hands to improve the firmness and elasticity of these parts, reduce fine lines and sagging, and make the skin younger and more vibrant.
4. Whitening and spot-lightening raw materials: It can increase the density of the skin by promoting the growth and movement of skin cells, making the skin look fuller and more elastic. It can also control the production of pigments, reduce spots, and make the skin color more even and brighter. It can be used as a raw material for functional skin care products to provide whitening effects for the skin.
5. Anti-inflammatory and repairing effects: Acetyl tetrapeptide-9 also has the ability to resist inflammation and repair the skin, which can reduce skin inflammation and help injured skin recover and regenerate. Therefore, it can also be used for sensitive or damaged skin.
