Snap-8 is a synthetic peptide that is used in skincare products to improve the appearance of wrinkles and fine lines. It is a small molecule peptide easily absorbed into the skin and is often used in anti-aging skincare products. Snap-8 is said to mimic the body's growth factors and stimulate the production of collagen and elastin, which are responsible for the skin's youthful appearance. It also helps to improve skin elasticity and firmness, reduce the appearance of wrinkles and fine lines, and increase skin thickness. Additionally, Snap-8 has been shown to improve skin barrier function and increase moisture retention, making the skin more hydrated and healthy.
