At night, apply a thin, pea-sized layer to clean, dry skin, 20 to 30 minutes after washing. That amount covers the whole face. More won't work faster, it will only irritate.
Ramp up gradually: every third night for two weeks, every other night in weeks 3 and 4, then nightly as your skin tolerates it. The dermatologist on your clinical team sets and adjusts your plan. Advanced needs a slower start than Core.
Follow with a barrier-supporting moisturizer.
Every morning, wear a broad-spectrum SPF 30 or higher. Tazarotene makes skin significantly more sun-sensitive than first-line retinoids, and that lasts for weeks after stopping.
Do not use if you are pregnant, may become pregnant, trying to conceive, or breastfeeding. Tazarotene is FDA Pregnancy Category X and can cause birth defects. Effective contraception is required during treatment. If you become pregnant, stop use and contact your DermClick care team.
