For effective skin lightening, I have found that it is better to perform a light enzyme peel before applying the skin lightener. Perhaps it allows the lightener mix to penetrate deeper and thus have a greater effect. The only lightener combo I use is a mixture of kojic acid, azelaic acid, licorice extract, lactic acid, citric acid, salicylic acid and distilled hamamelis.
