how to use tretinoin and benzoyl peroxide simultaneously

[Deleted member 122490]

i use a cream that has 5% benzoyl peroxide and %1 clindamycin which creates forms into a layer on my skin when it dries. i apply it before going to bed because iirc blue light renders it useless and remove the dried cream with cold water after waking up. so my question is how can i fit tretinoin into this schedule? should i let my skin absorb it first before applying benzoyl peroxide or do something else?
