Are peptides really the best way to moisturize? Science says…

Hey Reader!

This week, let’s put the “hydration hero” claim to the test.

Peptides Deeply Hydrate Your Skin?

Some brands say peptides are ultra-hydrating, even rivaling hyaluronic acid. The truth? Peptides aren’t classic humectants. They don’t draw water into the skin like hyaluronic acid or glycerin. But they do have the ability to hold onto extra water. Additionally, some may help strengthen your skin’s barrier over time, so you lose less moisture. But if you want instant hydration, classic moisturizers still win.

Even more is coming next week, but if you are curious now, you can read the full article.
