I love these! I get a lot of chemical peels/microneedling/etc and these are great for after treatment for a few days. If I could afford them for everyday I would. They are GREAT! Easy to use (warning-- they are glass and you do need to be careful) and absorb quickly. I also have the hydration one, but my fav is the collagen concentrate. I feel that they enhance the procedure I received and speed up healing time. These are expensive but worth the splurge in my opinion.
