Psoriasis is a serious, immune-driven illness that affects around 2% of the population and has a wide range of clinical manifestations 1-3 . Many patients have localized illness, and topical therapy can be an important part of treatment.

tazarotene is the first receptor-selective retinoid for the topical treatment of plaque psoriasis. On application, tazarotene is rapidly hydrolyzed to its main metabolite, tazarotenic acid, which binds to retinoic acid receptors (RARs) in the nucleus. Tazarotenic acid selectively binds to RARs b and g . The predominant type of RAR expressed in the human epidermis is RAR, indicating that it may be an important mediator of retinoid action in skin. .

Topical Corticosteroids is commonly used in situations of mild to moderate disease severity. However, long-term safety is still an issue, especially when utilizing stronger formulations,which come with a higher risk of local cutaneous adverse events (AEs). Telangiectasia, suppression of the hypothalamic-pituitary-adrenal (HPA) axis, and skin shrinkage are some of these negative consequences. By regulating gene transcription, tazarotene normalizes abnormal keratinocyte differentiation, reduces epidermal hyperproliferation, and decreases inflammation, the three pathogenic factors in psoriasis, thereby producing a more normal expression of skin differentiation in psoriatic lesions
