What Is Acetyl Tetrapeptide-5?
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.
How Does Acetyl Tetrapeptide-5 Works?
- nhibits glycation in the skin around the eyes. Glycation normally causes abnormal and disorganized crosslinking in the collagen fibers which causes the skin to be less elastic. This peptide binds to one of the proteins (SOD) that is involved in the Glycation, preventing this protein from binding to the next substance necessary to continue glycation and, therefore, stops this process.
- Decreases the permeability of the blood vessels in the area and, thereby, decreases the amount of fluid that can accumulate in the periocular area.
What Is the Application of Acetyl Tetrapeptide-5?
While Acetyl Tetrapeptide-5 is most often found in eye creams it is also found in shampoo, conditioner, frizz serums, lotions, creams, lip treatments, cleansers, after-sun lotion, soap and body lotions.
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. Humectants can also play an important role as emulsifiers within an overall formulation according to the Cosmetics Database.
