Adapalene 0.3% is not available over the counter. Only the lower-strength 0.1% gel is sold without a prescription, marketed as Differin Gel since the FDA approved its over-the-counter switch in 2016. The 0.3% concentration remains prescription-only in the United States, and getting it requires a visit with a healthcare provider or a telehealth consultation.
Why Only the 0.1% Strength Went OTC
Adapalene was first FDA-approved as a prescription acne treatment in 1996. Twenty years later, the FDA moved the 0.1% gel to over-the-counter status for people 12 and older, making it the first retinoid available without a prescription in the U.S. The 0.3% gel, approved as a prescription product in 2007, was deliberately kept behind the pharmacy counter.
The FDA’s own review documents show that regulators were specifically concerned about confusion between the two strengths. Because both are gels sold under the Differin name, the agency flagged the risk of “wrong strength errors” if both were available on store shelves. Keeping the 0.3% as prescription-only creates a clear separation: if you’re buying it off the shelf, it’s 0.1%; if a doctor wrote it, it could be 0.3%.
How the Two Strengths Compare
Both concentrations work the same way. Adapalene speeds up skin cell turnover, which keeps pores from clogging, and it has anti-inflammatory effects that calm red, swollen breakouts. The difference is potency. In clinical studies, adapalene 0.3% produced a 61% median reduction in inflammatory lesions (the red, painful kind) and a 51% reduction in noninflammatory lesions (blackheads and whiteheads). The 0.1% strength works well for mild to moderate acne, but dermatologists typically reserve the 0.3% for patients who haven’t responded enough to the lower dose or who have more stubborn breakouts.
The higher concentration does come with more irritation potential. Dryness, redness, and peeling are common side effects of any retinoid, and they tend to be more noticeable at the 0.3% strength, especially in the first few weeks. That said, tolerability studies comparing adapalene 0.3% gel to other prescription retinoids found it performed similarly in terms of side effects, meaning it’s no harsher than comparable alternatives your dermatologist might prescribe.
What Forms Are Available
Adapalene 0.1% comes in multiple formulations: gel, cream, and lotion. The 0.3% strength is only available as a gel. All formulations of adapalene 0.1% other than the gel (the cream and lotion) also remain prescription-only. So the only truly over-the-counter option is adapalene 0.1% gel, sold as Differin Gel or store-brand equivalents at most pharmacies and drugstores.
How to Get Adapalene 0.3%
You’ll need a prescription from a doctor, dermatologist, or telehealth provider. Many online dermatology platforms now offer consultations specifically for acne, which can make the process faster than booking an in-person appointment. If your provider determines the 0.3% strength is appropriate, they can send the prescription directly to your pharmacy.
Cost varies depending on your insurance. Without coverage, the generic adapalene 0.3% gel runs around $36 for a 45-gram tube when using a pharmacy discount card. The brand-name Differin 0.3% costs significantly more without a coupon. With insurance that covers dermatology prescriptions, your copay may be lower, though some plans require you to try the 0.1% strength first before approving the higher concentration.
Starting With 0.1% First
If you’re considering adapalene for the first time, starting with the over-the-counter 0.1% gel is a reasonable approach. Many people see meaningful improvement at this strength within 8 to 12 weeks. Retinoids work gradually, so the common mistake is giving up too soon or assuming a higher dose is needed before the lower one has had time to work.
If you’ve been using adapalene 0.1% consistently for three months and your acne hasn’t improved enough, that’s a good reason to talk to a provider about stepping up to 0.3%. They can also evaluate whether combining adapalene with other treatments, like benzoyl peroxide, would be more effective than increasing the retinoid strength alone.
Availability Outside the U.S.
In Canada, adapalene 0.3% is also prescription-only, sold as Differin XP Gel. Availability and legal status vary by country, but the 0.3% strength generally requires a prescription in most markets where it’s sold, including the UK and Australia. The over-the-counter availability of adapalene 0.1% that exists in the U.S. is not universal either; some countries still require a prescription for all adapalene strengths.
