How to use tretinoin
Tretinoin is usually supplied as a cream or gel. The dosage and frequency depend on your age, skin type, and the condition being treated, but it is generally applied once daily to the affected areas.
Before applying tretinoin, wash your face gently with a mild cleanser and warm water, then wait 20-30 minutes to ensure your skin is completely dry. Use only a small amount, spreading it lightly over the affected area, and wash your hands after application. Avoid leaving excessive medication on your skin.
Tretinoin can make your skin more sensitive, so it’s important to avoid harsh exfoliants, abrasive cleansers, or sulfur-based acne products, which can increase irritation. It also increases UV sensitivity, so apply sunscreen daily and limit sun exposure. Use a gentle moisturizer to reduce dryness or irritation. Be cautious if you are taking other drugs or supplements that increase photosensitivity, like certain antibiotics.
Most people apply tretinoin at night, but your provider can guide you on whether it’s safe to use every night or if alternate-night application is better while your skin adjusts. Consistent, long-term use as prescribed is needed for best results. Do not discontinue or increase the dose without medical advice.
