I have sensitive and veryyyy dehydrated skin, my skin hydration level was at 24.3% 2 and a half weeks ago, that is terribly dehydrated. And now 2 and a half weeks later i'm now at 40%, that is incredible! especially since I live in such a dry area. This is the only moisturizer I've found that doesn't break me out, doesn't make my skin feel oily, doesn't clog my pores, hydrates all day, and is light enough to wear under makeup. This will forever be a staple in my skincare regimen.
