Tazarotene is a synthetic retinoid medication that acts as a selective agonist of the skin retinoic acid receptors. It is used topically to treat psoriasis by reducing inflammation and controlling the overgrowth of skin cells. The drug binds to specific nuclear receptors which modulate gene expression involved in cell differentiation and immune signaling. This interaction slows the rapid proliferation of keratinocytes and dampens the inflammatory cascade that characterizes psoriatic lesions. By promoting the normal maturation of epidermal cells, Tazarotene helps restore the barrier function of the skin and improves lesion clearance. Overall the active ingredient produces therapeutic effects through selective activation of retinoid pathways that regulate cell growth, inflammation, and skin remodeling.

Tazarotene is a synthetic topical retinoid medication used primarily for the treatment of plaque psoriasis and acne vulgaris. It functions by activating specific retinoic acid receptors in skin cells to regulate cell growth and differentiation. Binding to these receptors modulates the expression of genes involved in keratinocyte proliferation and inflammation. This biochemical action reduces the overproduction of skin cells and suppresses inflammatory responses. The resulting normalization of skin cell turnover leads to clearance of lesions and improvement of skin appearance. Because it acts directly on molecular pathways, Tazarotene provides a targeted therapeutic effect without systemic absorption.

Tazarotene sometimes causes mild skin irritation such as burning or stinging after application. Dryness of the treated area is a frequent side effect reported by users. Redness or mild swelling may appear, especially during the initial weeks of treatment. Some people experience peeling or flaking as the skin adjusts to the medication. An increased sensitivity to sunlight can occur, making the skin more prone to sunburn. Itching or a tingling sensation may develop in localized spots. A temporary worsening of acne lesions is possible before improvement sets in. Most side effects are mild and tend to diminish with continued use.

It can cause skin irritation at the application site. Redness and itching may appear on treated areas. Dry or flaky skin can develop during treatment. A burning or stinging sensation may be felt after application. Peeling of the outer skin layer is possible. These effects are generally mild and transient.
