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 price for the amount! It seems to be working well as a cleanser so far. It is a bit on the drying side for me though. It leaves a little bit of a squeaky touch to my face which resolves with moisturizer, but would not want to use without follow up moisturizer. I’ll probably try a different cleanser next time with less harsh ingredients since my skin is on the sensitive side, but it may be a Show more

So far the worst cleanser ever. It stripped my skin so bad and broke me out. It dried out my skin and after using it for like one week, my face started to feel very sensitive and it hurt too. Had to go to dermatologist all because of this cleanser.

HG acne scar serum
Initially, this serum had helped fade away most of my old acne scars. After while, I thought it didn't do anything more for my new acne growth. So I ditched this serum for about 3 months and tried other new niacinamide products. I REGRET it. Soon after, I got more and more whiteheads and acne. My skin texture becomes uneven and dry. The new acne scars couldn't fade away at all. Show more
