I am using this almost 2 months and i was waiting for clear result. Honestly it is best. I only used 10% Lactic Acid, and resuls are very good, my pigmentation are almost clean, its a very good product, i will rerate it after fully clear my skin, let me clear that i had hyperpigmentation almost 8 year. And i was afraid to use anything so i wanted only safe, before using is I made sure that it is safe for my skin. Really it safe and very good. Thank you derma co.
