This skin care regimen is the truth for medium to dark brown skin tones! I have been using the system for 15 days and I have already seen more progression than I ever have in my whole life. I have tried every product under the sun until my aesthetician introduced me to this brand. The Mandelic Acid is making me peel and flake like crazy, but this means progression is taking place. The acid is causing my sub dermal acne to re-surface, allowing to target these issues, as well as my stubborn hyperpigmentation. If these are the results in just 15 days, I can’t wait to see what this regimen will result in after three months! I’m excited!
