- you would rather it just work, without depending on the product being at the right pH

Pregnancy: Retinol should be avoided in pregnancy, and Salicylic acid (BHA) is one to check with your doctor first.
Can you use them together?
Use with careUse these with care.
Retinoids and exfoliants both speed up cell turnover, so on the same night their irritation adds up, most of all while your skin is new to either.
Do this: Use them on alternate nights rather than the same evening; once both are old friends, your skin decides.

How to introduce Retinol and Salicylic acid (BHA)
- Patch test each one first: a coin-sized amount on your inner forearm for two or three days, watching for redness or stinging.
- Alternate nights: Retinol one evening, Salicylic acid (BHA) the next, so your skin only handles one of them at a time.
- Start the retinoid at once or twice a week and increase gradually, giving your skin time to settle between steps.
- If skin turns tight, flaky, red or starts to sting, drop back a step and let your barrier recover for a few days before pushing on again.
There is room for both here, as long as you build up gently and let your skin set the pace.
For your skin type If your skin is sensitive or reactive, take this pair slowly: Retinol is the higher-irritation ingredient here, and using actives close together magnifies that.
