Adapalene vs tretinoin: which retinoid is right for you?

Adapalene and tretinoin are both retinoids for acne, and the biggest practical difference is how you get them. Adapalene 0.1% gel, sold as Differin, is on the pharmacy shelf. Tretinoin needs a prescription in every strength. On acne, the two performed about the same in a pooled analysis of five trials, with adapalene causing less irritation. Tretinoin’s advantages are a wider range of strengths and an FDA approval for fine wrinkles.

Adapalene vs tretinoin at a glance

How they compare on acne

The most direct comparison is a 1998 meta-analysis in the British Journal of Dermatology. It pooled five randomized, investigator-blinded trials with 900 people with mild to moderate acne: 450 used adapalene 0.1% gel and 450 used tretinoin 0.025% gel. Adapalene was equivalent at reducing total lesion counts, worked faster in the first week, and had “considerably greater local tolerability at all evaluation periods” (Cunliffe et al.).

One caveat: the tretinoin in that analysis was the lowest common strength, 0.025% gel, so it doesn’t tell you how adapalene stacks up against tretinoin 0.05% or 0.1%.

Each drug also has placebo-controlled data on its label:

• Adapalene. In a 12-week trial of 653 people aged 12 to 52, 21% on adapalene 0.3% gel and 16% on 0.1% gel were rated clear or almost clear, against 9% on the plain gel (label).
• Tretinoin. In two 12-week trials of Retin-A Micro 0.1%, total acne lesions fell 45% and 32%, against 23% and 16% on the plain gel (label).

Those trials measured different outcomes in different people, so they can’t be compared head to head.

Irritation

Both cause the same kinds of irritation: redness, dryness, peeling, burning and itching, usually worst in the first weeks. The adapalene Drug Facts say irritation is more likely in the first few weeks and when you use more than one acne product, and usually lessens with continued use (label). In the Retin-A Micro 0.1% trials, irritation peaked in the first two weeks and 6% stopped because of it.

Both labels also warn that acne may look worse at first. The adapalene label calls this normal and says to keep going unless irritation becomes severe; the tretinoin label says the early flare “should not be considered a reason to discontinue therapy.”

If irritation has stopped you before, the 900-patient analysis suggests adapalene 0.1% is the gentler start.

Wrinkles and sun damage

Here tretinoin has the clear edge on paper. Renova 0.02% tretinoin is FDA-approved to help soften fine facial wrinkles in people who also use sun protection. In five 24-week trials, 60% of lightly pigmented patients had at least minimal improvement in fine wrinkling, against 39% on the plain cream (label). The label also says it doesn’t eliminate wrinkles or repair sun damage, and results can take 6 months.

Adapalene’s labels cover acne only. Many online providers sell tretinoin specifically for anti-aging; see our best prescription anti-aging creams.

How to use each

Adapalene 0.1% (over the counter). Once a day on clean, dry skin, a thin layer over the whole affected area, for adults and children 12 and older. Don’t use it more than once a day. Avoid damaged, sunburned or eczema-affected skin, limit sun exposure and use sunscreen, and don’t wax treated areas. The label says it may take up to 3 months of daily use to see results, and to stop and ask a doctor if you see no improvement by then.

Tretinoin (prescription). Once a day before bed, enough to cover the area lightly. Results should show after 2 to 3 weeks, though more than 6 weeks may be needed (label). Minimize sun exposure, avoid sunburned skin and eczema, and use caution with other drying or medicated products. Our tretinoin side effects guide covers the first weeks.

Using them with other acne treatments

Neither label recommends stacking several drying products at once. The adapalene Drug Facts say irritation is more likely if you use more than one topical acne medication at a time, and the tretinoin label urges caution with medicated or abrasive soaps, drying cosmetics and products containing sulfur, resorcinol or salicylic acid. Prescribers do combine retinoids with other treatments, such as clindamycin, and an approved gel pairs clindamycin 1.2% with tretinoin 0.025%. Let your clinician decide what to combine, and don’t use adapalene and tretinoin together unless told to.

Pregnancy

Ask a clinician before using either one if you are pregnant, trying to conceive or breastfeeding. The adapalene Drug Facts say to ask a doctor before use if pregnant or breastfeeding, and to stop and ask a doctor if you become pregnant or plan to. The prescription adapalene label says there isn’t enough human data to establish a risk, and that very high oral doses caused malformations in animals. The Renova tretinoin label says not to use it if you are pregnant or trying to become pregnant.

Cost

Adapalene 0.1% is sold without a prescription, so you pay the shelf price and no clinician fee. Tretinoin needs a prescription; online, the providers we track that publish a price charge $28 to $35 a month. As of October 18, 2026:

Which one to choose

• Start with adapalene 0.1% if you have mild to moderate acne, want to try a retinoid without a prescription, or have found retinoids irritating before.
• Ask about tretinoin if adapalene hasn’t helped after 3 months, you want a stronger or different strength, or fine wrinkles are part of the goal.
• Ask about adapalene 0.3% if you want to stay with adapalene but need more than the over-the-counter strength.
• For hormonal acne in adult women, a clinician may add spironolactone; see spironolactone for acne.

The bottom line

Adapalene 0.1% is the easy first step: over the counter, about as effective as tretinoin 0.025% in a 900-patient analysis, and gentler. Tretinoin needs a prescription but comes in more strengths, is approved for fine wrinkles as Renova, and costs $28 to $35 a month online where a price is published, as of October 2026.
