Analysis of three commonly used peptide ingredients in cosmetics

1. Structural characteristics of palmitoyl pentapeptide-3/4 (Matrixyl): Contains 5 kinds of amino acids, with a 16-carbon aliphatic chain bound to the N-terminus, and has the properties of both palmitic acid and collagen.

Efficacy: By mimicking repair signals, it promotes the production of collagen (type I, II, and III), strengthens its combination with glucosamine, stimulates the production of hyaluronic acid, etc., improves skin's moisture content, thickness, firmness, and radiance, and reduces fine lines.

2. Structural characteristics of Acetyl Hexapeptide-8 (Argireline): It has a specific chemical structure.

Efficacy: Promotes cell activity and increases collagen, interferes with neuromuscular information transmission, relaxes facial muscles, effectively reduces fine lines on the forehead and around the eyes, comparable to botulinum toxin type A, and also has moisturizing and anti-oxidation effects.

3. Structural characteristics of palmitoyl tripeptide-5: a mature beauty peptide in the market.

Efficacy: Accelerates collagen formation, enhances cell activity, increases skin elasticity and moisture content, improves skin tone and radiance, inhibits tyrosinase activity, inhibits pigmentation, and has a whitening effect (recent studies have found).

The three peptides each play an important role in cosmetics:
Palmitoyl Pentapeptide-3/4 is mainly used for anti-aging and smoothing fine lines;
1. Reduce wrinkles: reduce the intensity of muscle contractions, as well as minimize and soften fine lines;
2. Anti-aging: Prevents fine lines caused by repeated facial movements and increases collagen and elastin matrix, helping to prevent premature aging

Acetyl Hexapeptide-8 focuses on anti-wrinkle and firming, especially for facial wrinkles;
1. Anti-wrinkle: Reduce the appearance of fine lines and wrinkles by reducing the contraction of facial muscles;
2. Skin firming: Increase the synthesis of collagen and elastin, improve skin elasticity and firmness;
3. Moisturizing: Increase skin moisture content, improve skin hydration and smoothness;
4. Antioxidant: neutralize free radicals and reduce oxidative stress damage to the skin

Palmitoyl Tripeptide-5 performs well in anti-wrinkle, skin conditioning and whitening.
1. Anti-wrinkle: Promote the synthesis of collagen (type I, type I and type I) to make the skin more
Look younger and more elastic;
2. Skin conditioning: Promote skin cell growth, inhibit oxygen free radicals and hydroxyl free radicals, and increase the production of elastin, hyaluronic acid, glycosaminoglycans and fibronectin
They provide cosmetics with a variety of functions to meet the skin care needs of different consumers.
