If you’re already on the retinol train, you may consider adding a chemical exfoliant to your skin care routine as well (just don’t use them on the same night!).

What’s more, studies have shown that six months of using topical glycolic acid stimulated a 27% increase in epidermal thickness. This is exactly what you want for tighter, younger-looking skin.
Plus, glycolic acid is an AHA, meaning it’s simultaneously exfoliating and hydrating. You can read more about the ins and outs of this powerhouse ingredient here, if you’re curious.
