Adapalene
Adapalene is a topical retinoid used for acne. It affects cell differentiation and keratinisation within follicles, helping reduce the formation of comedones.
Key points
- Adapalene binds selected retinoic acid receptors in the skin.
- Local dryness, redness and irritation are common early treatment effects.
Differin is attached to acne vulgaris as a topical adapalene product. The tube and topical route matter more to ingredient recognition than repeating its concentration in prose. Sun sensitivity and irritation are directly relevant to this retinoid’s skin action.
