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.

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!

No more acne, very slow at reducing pigmentation tho
The only retinol my partner's skin can tolerate.
Their skin is extremely reactive and sensitive but this retinol has worked great.
I also use it every other day because I alternate between this retinol and A313.
It works great and is gentle enough to allow me to build tolerance without purging effects (at least on my skin and my partner's)

I don't really have a lot of cystic acne or large noticeable skin issues so honestly, I didn't see very obvious results or large differences. But, however, I have noticed my skin feeling smoother, the skin tone feeling more even, and a lack of newly developed acne after using this every day for 3 weeks. This product is a good preventative measure and overall well formulated however you have to Show more
