How to use them
Alternate nights, for example Adapalene on Monday, Wednesday and Friday and PHA on Tuesday and Thursday, with a plain moisturiser night in between if your skin feels sensitive. If your skin is resilient and already used to both, you can try layering them: apply PHA first, wait a few minutes, then apply Adapalene.

Frequently asked questions
Can I use Adapalene and PHA together?
Yes, but not at the same time. Both Adapalene and PHA speed up cell turnover. Used in the same routine they commonly cause redness, peeling and a damaged barrier, especially in India's heat and humidity. Alternate nights instead.
Which goes first, Adapalene or PHA?
Apply PHA first, then Adapalene. The general rule is thinnest to thickest texture, and lowest pH first. For this pair, though, it is better not to layer them in the same routine at all.
Should I use Adapalene in the morning or at night?
Adapalene: best at night. Apply a thin layer to the whole acne-prone area at night, not just on spots. Expect a purge for 4–6 weeks. Use a moisturiser and daily SPF.
Should I use PHA in the morning or at night?
PHA: works morning or night. You can use it daily. It is a good first acid, or a way to keep exfoliating on retinoid "rest" nights if your skin tolerates it.
Is Adapalene with PHA safe during pregnancy?
Adapalene is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
