I've been using Curology for about 3 - 4 months now. I've tried to treat my own acne through store-bought products but nothing ever seemed to work. I was skeptical of Curology but after reading reviews I decided to give it a shot. The products they recommended to me in my treatment plan did not have the usual acne-fighting ingredients you find in store-bought products (e.g. salicylcic acid or benzoyl peroxide). Within just 3 weeks I started to see results from the Curology treatment plan! I haven't seen my skin so even-toned, smooth, and breakout-free since before puberty. This stuff is such a life-changer. For the first time in 12 years I feel comfortable not wearing makeup in public. My one and only complaint is that I usually run out of one bottle before receiving my next shipment. However, I usually only run out 2 days prior to the shipment.
