If you have not heard of this product, you need to learn. This combination of products is used to even out the pigmentation from Melasma, sun damage, aging or other reasons. But this product can also brighten and tighten up your skin. Dermamelan has a 30% higher concentration of products, compared to Cosmelan 2, so we use this to treat the superficial and deep skin damage and pigmentation issues. If you are not sure if you have superficial or deep damage, please ask us. We also recommend using Vitamin C and sunscreen while using this product. We love these results!
