Dark spots after acne and hydroquinone
Without knowing more or seeing a picture it is difficult to answer this question. It sounds like you have post-inflammatory hyperpigmentation from acne which can take months to fade even with the use of hydroquinone. If you get irritated from the use of hydroquinone, this can also cause hyperpigmentation. Rarely, with long term abuse of hydroquione, dark nodules of exogenous ochronosis can develop and these are often permanent. I suggest you discuss this problem with a board-certified dermatologist.
