Adapalene vs Tretinoin
Adapalene vs Tretinoin — two prescription-strength retinoids widely used for acne, with adapalene now available over the counter in some regions. Adapalene is a synthetic, photostable retinoid known for a favorable tolerability profile in acne, while tretinoin is a longer-established retinoid used for both acne and photoaging.
Key points
- Adapalene is available over the counter at 0.1% in some markets, while tretinoin typically requires a prescription.
- Adapalene tends to be more stable in light and is often reported to cause less irritation than tretinoin at comparable use.
- Tretinoin has extensive evidence for both acne and signs of photoaging such as fine lines and pigmentation.
- Both increase sun sensitivity and are used at night, so consistent daily sunscreen is important, and neither should be used in pregnancy without medical guidance.
