For most treatment-naive or sensitive skin, over-the-counter adapalene 0.1% fits best because it works similarly and irritates less. Tretinoin fits better when you need prescription strength choices or care about photoaging and a clinician guides selection.
Both are topical retinoids, vitamin A-based gels or creams that keep pores clear and calm acne. Current American Academy of Dermatology guidelines recommend topical retinoids at every acne severity stage for patients aged 9 and older, according to AJMC current dermatology guidelines. Your choice turns on tolerability, access, and safe use.

How well does each clear acne?
A 12-week, multicenter randomized investigator-masked trial in 168 acne patients found comparable efficacy, according to the randomized trial summarized by Penn State randomized trial summary. Adapalene gel 0.1% matched tretinoin microsphere gel 0.1% for inflammatory, noninflammatory, and total lesions with similar onset.
A prior meta-analysis of five randomized trials found adapalene 0.1% as effective as tretinoin 0.025%. Results depend on the specific concentration and vehicle compared, so no strength wins for every case.
Which feels gentler on skin?
Penn State/Cutis investigators reported significantly better scores for erythema, scaling, dryness, pruritus, and stinging/burning with adapalene 0.1%. They also recorded fewer treatment-related adverse events with adapalene.
If your skin burns, peels, or turns red easily, that gap matters. Redness, dryness, and stinging often decide whether you keep using the product long enough to see clearing.
How do access and options differ?
Adapalene gel 0.1% became the first full prescription-strength retinoid sold over the counter in the U.S. on July 8, 2016.
It is approved for acne in people 12 and older, while no tretinoin product is available OTC, according to the approval notice from Galderma approval notice. Sensitive-skin or treatment-naive users often start with OTC adapalene 0.1% once daily to the full affected area, according to GoodRx treatment comparison. GoodRx notes tretinoin offers multiple prescription strengths and formulations with broader evidence for photoaging, so a clinician should select the match.
How do you use them without harming skin?
The DailyMed tretinoin label directs users to minimize sun exposure and use sunscreen and protective clothing. It also directs users to apply only at bedtime, because retinoids increase sun sensitivity and tretinoin degrades in light.
The DailyMed adapalene file warns for external use only and not on damaged or sunburned skin. It also advises limiting sun and tanning-bed exposure, using sunscreen, and asking a doctor before use if pregnant or breastfeeding.
- Apply once daily to the full affected area, not spots only.
- Use at night, moisturize, and wear sunscreen daily.
- Pause on sunburned or broken skin and ask a clinician if pregnant or breastfeeding.
