What are peptides and what do they do in skincare?

Peptides are short chains of amino acids, which are the building blocks of proteins. In skincare, they play a crucial role in various functions, most notably in stimulating collagen production. Collagen is a key protein that contributes to the skin's structure, firmness, and elasticity. As we age, collagen production naturally decreases, leading to the appearance of fine lines and sagging skin. The application of peptides in skincare products can help to signal the skin to produce more collagen, thereby promoting a more youthful appearance and improving overall skin texture.

Peptides can also support the skin's barrier function, enhance hydration, and provide anti-inflammatory benefits, making them valuable ingredients in many skincare formulations. Their ability to penetrate the skin and exert these effects is what makes them particularly beneficial in aesthetics and skin rejuvenation practices.
