Retinoid + BHA
Keep them apartKeep them apart. A retinoid plus a BHA (salicylic acid) in the same session can over-exfoliate and sting, especially if your skin is already dry or reactive.
Both earn their place - retinoid for cell turnover, BHA for pores - so split them instead of dropping one. Alternate nights, or BHA in the morning and retinoid at night.
Watch the hidden duplicates: salicylic acid shows up in cleansers, toners, and spot treatments, so you can stack this pair without meaning to. Rinse-off products are gentler on contact time, but a leave-on BHA plus a retinoid is the combination to schedule.
Patch-test, introduce one at a time, and moisturize - a supported barrier tolerates actives far better.
