Acetyl Tetrapeptide-5, a synthetic peptide, is thought to prevent glycation, a process in skin that weakens the skin's supportive components, resulting in wrinkles and loss of firmness.
What are the benefits?
When applied to the skin, it has a soothing, smoothing, hydrating, and firming effect. Its soothing effects are thought to reduce undereye puffiness caused by fluid accumulation, such as allergies. Undereye puffiness is different from undereye pockets, which are caused by fat pads under the skin slipping out of place.
