A 27-year-old female asked:
Is it right that lamp light may decrease the effects of tretinoin ?

Light and tretinoin: There was previously a suggestion that uv light (sunlight) inactivated tretinoin, but that has not been substantiated. No suggestion that other light, like lamp light inactivates tretinoin.
