I use a product called Dr. Varon's Skin Bleaching System, and it's really helped my complexion. It's a three step system that consists of a dermabrasion cream (not a scrub), a skin brightening lotion, and a lightening treatment. The lightening treatment I'm not actually sure does much at all...It contains hydroquinone 2%, but it also contains mineral oil, which blocks penetration of the hydroquinone. The brightening lotion, however, is almost worth buying the entire package alone...and I follow up with the lightening treatment, just because I'm not convinced it's completely useless, even though my instincts tell me it is. It contains a number of ingredients, but two of the first five mentioned are glycolic acid and azelaic acid. Others are lemon peel, comfrey, chamomile, garlic, and a number of chemicals I'm not sure about. Anyhoo, it's the only product I've found that contains azelaic acid. I'm acne prone, and I might possibly have rosacea, all the women in my family have been diagnosed with it, and my skin is very sensitive, but I tolerate this product very well. I think it would be better, though, to use the dermabrasion cream and the skin brightening lotion, followed with a skin lightener that does not contain mineral oil, to see maximum benefits. The system can be ordered online, or found in a drugstore.
