This is a follow-up to last week's question about side effects of 4% hyrdroquinone. You mentioned people from Asia and Africa are more prone to this complication. Is this because of use of high concentration of hydroquinone for a long time or just their skin type. I have PIH (due to hair removal by tweezers) on my upper lip and my dermatologist prescribed 4% hydroquinone once a day in the evening. Before that I used Ambi for 3 months twice a day. There has been improvement and it continues to improve since I started hydroquinone, but I am concerned that I have been on it too long. My dermatologist doesn't seem to be too concerned about ochronosis. I am Asian Indian. Thank you very much for your input.
I agree with your dermatologist. Ochronosis is rare here and is linked to prolonged use of high concentrations most commonly found in other parts of the world. Dr. I
