They are excellent for those looking to support the skin’s structural integrity.
3. Neurotransmitter Peptides
Often compared to the effects of professional cosmetic procedures, these peptides, also known as peptide neurotransmitters, help in relaxing the look of facial expressions. They are a staple in my routine for targeting areas where fine lines tend to congregate.
4. Enzyme-Inhibitor Peptides
These specialized molecules work to slow down the natural breakdown of collagen. By preserving the existing proteins in the skin, they act as a protective barrier, which is why they are often included in premium anti-aging serums.
Why Peptides Have Become So Popular
Peptides in skincare have become popular for promoting healthier, smoother skin because they are versatile and generally suitable for most skin types.
