Acetyl tetrapeptisde-5 is a known humectant or hydroscopic moisturizer which helps reduce eye puffiness, improve skin elasticity as well as overall smoothness. This is done by attracting water from deep within in the skin to the outer-most layer of the skin (stratum corneum), taking advantage of this compounds hydroscopic properties (Making Cosmetics). Humectant rich formulas have also been used to treat xerosis (abnormally dry skin) successfully (PubMed).  Humectants can also play an important role as emulsifiers within an overall formulation according to the Cosmetics Database.

Other common humectants include glycerin, sorbitol, propylene glycol, hexylene and butylene glycol, MP Diol, urea, alpha hydroxy acids and other sugars.

Safety Measures/Side Effects:

Some humectants may be irritants at extremely high concentrations, but acetyl tetrapeptide-5 is generally considered non-hazardous to the body and the environment by the cosmetics database.
