Dr. Jart+ products never seem to disappoint, and this mask is no exception. This is HANDS DOWN my ride or die mask. Sephora describes this mask as "an ultra-fine microfiber sheet mask that helps combat breakouts and reduces the appearance of scars and uneven skin tone"...yes, yes, and yes. I typically use this mask at night so that the serum will have time to penetrate into the skin without applying makeup on top. I'll cleanse my skin as per usual, apply toner, and then apply this mask anywhere from 20-30 minutes. My skin feels instantly refreshed, and I notice that any blemishes that were there before look dramatically smaller/are completely gone. Bonus tip: there is a ton of serum in the package leftover even after you use the mask. I like to fold the package, clip it closed and store it in the fridge. If I feel like my skin needs that extra help, I'll apply the leftover serum all over my face or spot treat any areas that need a little extra TLC. A definite MUST in my collection!
