Acetyl tetrapeptide-5 is considered to be a moisturizer or absorbent that can help reduce eye
pufness, improve skin elasticity and overall smoothness. It uses the hygroscopicity of this
compound to absorb the moisture from the deep skin to the outermost layer of the skin (the
stratum corneum), thereby reducing pufness. Its moisturizing function makes it effective for
treating dry skin diseases (abnormal dry skin).
