Can Hydroquinine Damage Skin?
Doctor Answers 1
Too much hydroquinone can damage skin
Yes, hydroquinone can damage the skin and cause more darkening (called exogenous ochronosis) if used too long or in too high concentrations. Hydroquinone concentrations vary with different products (over the counter products usually contain 2%, most prescription creams have 4%, and compound formulations may have 6, 8, or even 12%). Those with higher concentrations or when used for long periods (greater than 6-8 weeks) are more likely to cause this (otherwise rare) problem.
You should consult a board-certified dermatologist and remain under his/her care for monitoring while using hydroquinone.
