What is adapalene?
Adapalene (brand Differin) is a third-generation synthetic retinoid developed for acne. Unlike tretinoin, which binds broadly to all retinoic-acid receptor subtypes, adapalene selectively binds RAR-β and RAR-γ — and that selectivity is why it's meaningfully less irritating than tretinoin while keeping comparable acne efficacy. It's also more photostable, so it holds up better in daylight (though sunscreen is still essential).
A practical advantage: adapalene 0.1% became available over the counter in the US in 2016, and is OTC or easily pharmacy-available in many markets, making it one of the most accessible "real" retinoids. It's also sold paired with benzoyl peroxide (e.g. Epiduo) for inflammatory acne, and at a stronger prescription 0.3%.
Gentle for a retinoid — but still a retinoid
Adapalene is the most tolerable of the prescription-grade retinoids, but it belongs to the family and carries the same risks at reduced magnitude. Expect an adjustment period ("adapalene purging"/retinoid dermatitis):
- Dryness and flaking in the first 2–4 weeks
- Mild redness as skin adapts
- Stinging on broken or sensitised skin
- Photosensitivity (less than tretinoin, but wear SPF)
- Eczema flares in atopic-prone skin — introduce carefully, ideally once eczema is controlled
As with all retinoids, this is irritation, not allergy, and it's managed by going low-and-slow (start every other night, build up over 4–8 weeks). And like all retinoids, avoid it in pregnancy and breastfeeding.
How to use it well
- Every other night to start, increasing as tolerated.
- Pea-sized amount to dry skin at night.
- Moisturise (and consider the sandwich method if sensitive/eczema-prone).
- Daily SPF — still needed despite its photostability.
- Pairs with benzoyl peroxide for inflammatory acne (adapalene tolerates this combination, unlike many retinols).
Gentler alternatives
- Sensitive/eczema-prone: azelaic acid (acne + pigment, far gentler) or niacinamide.
- Pore-focused, non-retinoid: salicylic acid.
- Pregnancy: azelaic acid, niacinamide, bakuchiol.
The bottom line
Adapalene is the accessible, modern acne retinoid — gentler and steadier than tretinoin, often available without a prescription, and effective for both breakouts and the post-acne marks they leave. Treat its early dryness as expected irritation (not allergy), respect the eczema and pregnancy cautions, and pair it with sunscreen.
