The Science of Skin Care: 4 Potential Uses for Peptides

Peptides are small segments of amino acids that occur naturally in the skin as part of the breakdown of proteins. They can also be manufactured for direct application to the skin. Thanks to their antimicrobial qualities and their ability to affect melanin and collagen production, synthetic peptides are showing promise in these four areas of skincare. 

Wound Healing

It is the antimicrobial qualities of peptides that appear to benefit wound healing processes. This could be a life-altering find for those who suffer from slow-healing wounds. Researchers like Ryan Smith Lexington KY are working diligently to discover the many medical benefits of peptides.

Diminishing Wrinkles

Fine lines and wrinkles develop partly because the skin loses its fullness and elasticity with age. By stimulating collagen production, and possibly even reducing the rate of collagen turnover, peptides may help to reduce these common signs of aging. 

Sun Protection

Peptides also appear to affect the melanin within your body. This is the pigment that gives color to your hair, skin, and eyes. Interestingly, melanin effectively blocks almost all harmful UV rays from the sun. Specific peptides, known as Melanin Activating Peptides (MAPs), directly impact melanin production. They are becoming more common in self-tanning products that produce a natural appearance, but scientists are also working to harness this process to develop new safe and effective sun protection products. 

Skin Lightening

In the same way that MAPs can be used to activate melanin, they may also be able to suppress it in cases of hyperpigmentation. This could result in a safe and natural way to lighten dark patches of skin without resorting to harsh bleaching processes.  

Scientists and researchers are continuously working to make improvements in skincare and beauty products. Their interest in and work with peptides have resulted in several new technologies that are producing impressive cosmetic results. These are now beginning to look at medical and health applications for the powerful skin-boosting properties of peptides.
