The way it feels on the skin is AMAZING!
First off, let me start off by saying I’m not one to comment on things i buy or try out of curiosity for how it’s going to look and feel on my skin. The second I put it on, I noticed how hydrating and smooth it seeps into my skin and felt a very big difference in my skin texture. I’ve also noticed over the course of a month and a half, my face has been glowy and I don’t have dry flakes or skin peeling from my face. I have combination skin and it’s hard for me to find a good hydrating face moisturizer with sunscreen and this really knocked it out of the park for me. I will be purchasing again as I already ran out of my bottle. It’s a little on the pricier side for how many ounces you get, but it’s definitely worth the buy and try.

Daily Useful
I absolutely love this sunscreen moisturizer! I wear it daily. It does not small like sunscreen and absorbs nicely into the skin. I highly recommend to any user. I also love the fact that it is FSA eligible! Bonus!
