Argireline (acetyl hexapeptide-8)
Argireline, also known as acetyl hexapeptide-3 or acetyl hexapeptide-8, is a synthetic six amino acid peptide used in anti-aging skin care products to reduce the appearance of fine lines and wrinkles.
Argireline has also been shown to promote collagen production. Collagen is a protein that is responsible for keeping the skin strong, firm, and youthful. As we age, the body produces less and less collagen. In fact, after the age of 20, a person produces about 1 percent less collagen in the skin each year. Moreover, environmental free radicals (from things like excessive sunlight exposure, smoking, pollution, etc.) can degrade collagen proteins. The result is skin that becomes thinner and more fragile with age. By promoting collagen production, Argireline may be able to increase skin firmness.
