Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

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!

TL;DR: HG! 🏆 The only thing keeping my skin from burning off while on retinoids! Great for sensitive skin. Helps with my acne, but not a surefire solution.

Before I was on retinoids again, I saw a really good clearing of acne on it. After tretinoin cream broke me into cysts, and I switched to Skinfix's Adapanoid Gel, this didn't solve the purge, but it DID make my usual skin sensitivity Show more

I used this consistently for about 8 months and although I enjoyed the clean feeling it gave me, I didn't notice obvious results, especially regarding clogged pores, closed comedones or pimples.

How this broke me out? I truly don’t know. I’m almost too embarrassed to admit it, but I know others have gotten cystic acne from this so I want to share my experience in case someone is questioning if it’s just them.

I also tried La Roche Posay's thermal spring water but this one is clearly superior. It actually calms and soothes irritated and inflamed skin.
