Retinoid · $15
Differin Adapalene Gel 0.1%
The only prescription-strength retinoid available over the counter in the US. Adapalene is a third-generation retinoid with unusually selective receptor binding, which is why it is effective against comedonal and inflammatory acne while irritating less than tretinoin at comparable strength.
Key ingredients
- Adapalene 0.1%
- Binds selectively to retinoic acid receptors involved in follicular keratinisation — the process that creates comedones in the first place. Stable in light and compatible with benzoyl peroxide, unlike tretinoin.
Texture and finish
A clear, alcohol-free aqueous gel. Dries quickly and can feel slightly tight; it is not moisturizing in any way and must be paired with a cream.
It suits you if
- You have blackheads, closed comedones, or persistent inflammatory acne
- You want prevention rather than spot treatment
- You can commit to twelve weeks of consistent use
Skip it if
- You are pregnant or breastfeeding
- Your skin is currently raw or over-exfoliated
- Your acne is nodulocystic and scarring — see a dermatologist first
Pros
- Prescription-strength efficacy at pharmacy pricing
- Stable alongside benzoyl peroxide, which most retinoids are not
- Well-studied for comedonal acne specifically
- One tube lasts several months at correct dosing
Cons
- Purge in weeks two to four is common and discouraging
- Drying — a good moisturizer is mandatory, not optional
- Not designed for anti-aging, though texture benefits are real
How to use it
- 1A pea-sized amount for the whole face, at night, on dry skin.
- 2Start every third night; build to nightly over six to eight weeks.
- 3Moisturize after, and wear SPF 30+ daily — adapalene increases sun sensitivity.
Where it fits in a routine
Night treatment step. Pair with a benzoyl peroxide wash in the morning and a ceramide moisturizer at both ends of the day.
