Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

Great for a compromised skin barrier. Feels super hydrating and occlusive -- similar to a snail mucin texture. Leaves a bit of a sticky/tacky finish, which doubles as a primer under makeup. Also makes the skin super glowy. WRP (just wish it was fragrance-free).
