Tazarotene gel is a topical retinoid used primarily to treat acne and plaque psoriasis. It works by normalizing skin cell growth and reducing inflammation, which helps clear blocked pores and reduce scaling or thickened patches of skin. Applied directly to affected areas, tazarotene can improve the appearance of skin over several weeks with consistent use. As with other retinoids, it may cause dryness or irritation, especially when first starting treatment, and sun protection is recommended during use due to increased skin sensitivity.
