Acetyl Tetrapeptide-5 description

A synthetic peptide that has calming, smoothing, hydrating, and firmness-enhancing benefits when applied to skin. Its calming properties are believed to reduce undereye puffiness due to fluid accumulation, such as from allergies (which is not the same as undereye bags that occur from fat pads beneath the skin slipping out of place).This peptide is also believed to interrupt a process in skin known as glycation, which can cause skin's supportive elements to weaken, giving way to wrinkles and loss of firmness. Acetyl tetrapeptide-5 seems to step in and help skin maintain a smooth resilience that results in a more youthful look.
