Made of palmitoyl tetrapeptide-7 and palmitoyl oligopeptide, this microcollagen pentapeptide fragment has been shown to help stimulate new collagen synthesis by acting as a “messenger” that signals skin cells to produce new collagen—our skin never loses the ability to produce new collagen, but it does slow down as we age. This pentapeptide works like a "slow, gradual collagen injection," which reduces the appearance of fine lines and wrinkles.
