Tripeptides are amino acids joined together by two bonds. They are a building block for proteins. Peptides are used in skincare products for their anti-aging effects.
Peptides have many beneficial effects on the skin. These include antioxidants, which are anti-inflammatory. In addition, they improve the skin’s appearance by smoothing out expression lines. Also, peptides have very limited side effects.
Aside from the positive effects on the skin, peptides also have an important role in the body. They are one of the body’s defenses against free radical damage. Free radical damage is the primary cause of cellular aging.
Peptides are also considered to be effective in hair transplantation. Several clinical studies have confirmed this effect. The peptides are thought to increase collagen synthesis and promote the growth of existing hair.
Another important function of a tripeptide is to inhibit the activity of dipeptidyl peptidase-4 (DPP4), an enzyme that plays a key role in cell apoptosis and fibrosis in the body. Various studies have shown that the use of a tripeptide that inhibits the activity of DPP4 reduces scarring during disease processes.
In addition, peptides have been shown to help the skin retain moisture and reduce red spots. These peptides have also been shown to reduce fine and coarse wrinkles.
There are several different peptides that have been tested for topical application in animal models. Most of them have good stability records. However, some open questions remain concerning peptide permeation. This will require new study designs to address these issues.
