A member asked:

Could hydroquinone 2% be used all the time? or are there long term side effects?

A doctor has provided 1 answer

Twice a day...: ...until the dark spots disappear. The only long-term side effect, if used too often or too long, is lightening of the skin. Paradoxical darkening of the skin has also been reported, but that's with higher strengths of hydroquinone.
