This treatment is suitable for skin suffering from Melasma, brown spots, blotchiness and hyper-pigmentation. This de-pigmentation peel is a two-part treatment. The initial treatment with Cosmelan or Dermalan is done in the clinic, which involves evaluation of the skin. After cleansing the skin the Cosmelan or Dermalan mask is applied and left on for around 4-8 hours depending on skin type. Following application, you can go home with the mask on. The second stage is the home maintenance programme, for which full instructions will be given. Cosmelan works in a similar way to Dermalan; however Cosmalan is the milder treatment of the two and is used for less severe pigmentation or for a general rejuvenating effect.
