Proteins in the skin are made up of peptides, which are amino acids. Peptides work in skincare products by enhancing your skin's natural communication system, which slows down with time owing to free radical damage. Reduced collagen production is a direct result of the deterioration in communication that comes with age, which adds to wrinkles, loose and sagging skin, and dull and uneven skin tone. Adding peptides to your skincare routine helps to reverse this damage, mend problem areas, and prevent further communication breakdowns. Peptides diminish uneven texture, wrinkles, and fine lines, and improve the overall appearance of the skin.
