Here at 111SKIN HQ we are so excited about our new Black Diamond Serum! It's a very concentrated version of our Black Diamond Cream, using black diamond technology that penetrates to the deepest layer of your skin to regenerate your skin. Its also packed with everything you'd want in a skincare! Arbutin to brighten, Hyaluronic Acid to retain moisture, and not to forget our patented NAC Y2 formula. 

I've been using it every night for weeks and have noticed a radiance to my skin that I normally get with mild peels or lasers! 

Have a nice weekend!
