I have adult, hormonal/cystic acne, and INCREDIBLY sensitive, dry, and dehydrated skin. I can't use any BHAs or AHAs, so I've been on the hunt for something that actually works without giving me an allergic reaction. NERD is IT! I haven't found anything else that works as well for my skin as NERD! It helps keep cysts from forming at the rate they normally do, and if I do get a pimple, it shrinks and heals quickly. My skin is definitely clearest when I use NERD and seriously, I've used EVERYTHING.
The only criticism I have is I wish that they offered smaller bottles since it is a bit of an investment. However, the treatment lasts a long time because you don't need much to cover your whole face, so the price is comparable to other premium brands (looking at you Sunday Riley).
Bite the bullet and try it, you won't be disappointed!
Bottom Line: Yes, I would recommend this to a friend
