What are the effects of peptides on the skin?

Nowadays, people’s pursuit of beauty is getting higher and higher. In the past, they may rely on makeup to modify their appearance, but this does not really change their appearance. So many people choose micro plastic surgery, but no matter which method they choose, people still hope to be naturally beautiful, so they put effort into skin care products. In the past two years, a skin care ingredient called peptide has become very popular, and the price has been driven very high. So what exactly is peptide? What effect does it have on the skin?

Peptides protect skin

The protection of small molecule peptides on the skin is closely related to their antioxidant effect. Dry skin and the appearance of pigmentation are manifestations of skin aging, and free radical damage is an important factor leading to these changes. Due to the influence of ultraviolet rays, pressure, metabolic waste and other factors, the free radicals in the body increase, causing the collagen fibers in the skin to age and break, making the skin loose, rough, dry, and wrinkled and with increased pigmentation. Small molecule peptides can enhance the activity of antioxidant enzymes such as superoxide dismutase and catalase, and reduce the level of malondialdehyde, a lipid peroxidation product. Therefore, small molecule peptides can scavenge free radicals, reduce damage to fibroblasts and collagen, avoid excessive cross-linking of skin collagen, and play a role in protecting the skin.

Small molecule peptides have very strong penetration into the skin. They can quickly activate epidermal cells, replenish nutrients for the skin, stimulate fibroblasts in the dermis, accelerate the synthesis of collagen, and have a variety of skin care and beauty effects.

5 major effects of peptides on skin

1. Moisturizing small molecule peptides and excited amino acids are important components of natural moisturizing factors and have extremely strong water-locking properties. Peptides contain a large number of hydrophilic groups (amino, hydroxyl, and carboxyl groups) on the surface of the molecular structure, which can absorb a large amount of water and form a film on the skin surface.

2. Nutritious small molecule peptides have strong skin penetration, can pass through the stratum corneum and combine with the skin epithelial tissue, participate in and improve skin cell metabolism, enhance the activity of collagen in the skin, maintain the moisture of the stratum corneum and the integrity of the fiber structure, enhance blood circulation, provide nutrition to cells, and achieve the effect of nourishing the skin.

3. Anti-aging and wrinkle removal The formation of wrinkles and fine lines is related to the natural loss of collagen. Peptides can directly penetrate into the dermis to replenish the lost collagen, reorganize the skin fiber tissue structure, restore skin elasticity, promote cell metabolism, delay cell aging, make the skin soft and smooth, and smooth fine wrinkles.

4. The skin color of white people is mainly determined by the melanin in the epidermal cells. If the content of thiamine in the skin increases and the activity of tyrosinase decreases, the production of melanin can be prevented. Small molecule peptides themselves contain a considerable number of sulfhydryl groups. Small molecule peptides also contain biological inhibitory factors, which can capture copper ions in tyrosinase and further inhibit the activity of tyrosinase, thereby reducing the amount of melanin formed. In addition, small molecule peptides also contain factors that lighten pigments. Small molecule peptides not only have the dual effects of preventing and fading, but also have the characteristics of whitening skin without rebound.

5. Repair small molecule peptides can directly penetrate into the bottom layer of the skin, directly repair degenerated cells, eliminate free radicals, assist cells in producing collagen, and reorganize skin fibrous tissue. 6. Renewal small molecule peptides also have anti-inflammatory and skin renewal effects. Small molecule peptides also have the effect of anti-hair loss and promoting hair growth
