This single product had more of an effect in one use than many other products I've used before. I've dealt with milas and scarring in my adult life (suffered from cystic acne in my teens and early 20s) and this product is helping those issues almost immediately. With the potent product, my skin did need extra moisturizer but I found the Clarity Serum brought it back to a moisturized state. I'm excited to continue using this product and see the results. Although the sticker shock might deter people, I found that a single use of this product was more effective than a facial which costs 3 times the amount of 1 bottle.
