Details
A four amino acid tetrapeptide that is designed to treat sagginess and unfirmness in mature skin. It works by inhibiting an enzyme (elastase) that breaks down proteins (e.g. collagen) as well as by stimulating type I collagen synthesis.
According to the manufacturer's in-vivo (made on real human) test, applying 4% Relistase for 8 weeks on mature women (avg. age 49) resulted in 14% improvement in skin elasticity and in increased skin tightness by 15.6%.
