Peptides
If you think you can't get a post-facial-like glow in the comfort of your own home, think again.
Peptides are some of the most innovative ingredients out there for improving the elasticity, firmness, and smoothness of your complexion. They're also usually paired with other nourishing ingredients to further bolster and maintain collagen and elastin production.
Peptides in skin-care products are designed to boost and replenish amino acids, which are the building blocks for collagen production.
