Can You Use Tretinoin With BHA?
Do not combine
Not in the same routine.
Tretinoin plus salicylic acid in one routine produces cumulative transepidermal water loss. The skin looks tight and shiny before it visibly peels.
How to use Tretinoin and BHA
Use tretinoin at night and reserve BHA for a separate morning, twice weekly at most.
