Mechanism of action

Tretinoin activates nuclear retinoic acid receptors (RAR-α, RAR-β, RAR-γ), which modulate transcription of genes involved in cell proliferation and differentiation. In the skin, it increases cell turnover, normalizes keratinization, reduces sebaceous gland activity, and has anti-inflammatory effects. These actions make it effective for treating acne and photoaged skin.
