Dermatology is a diverse specialty encompassing disorders and diseases of the skin, mucous membrane, hair and nails. Diseases in this category include acne, multiple inflammatory dermatoses, atopic dermatitis, psoriasis, occupational dermatoses and contact dermatitis.  
 
Physicians share widespread dissatisfaction with many of the current treatments because of poor efficacy, challenging safety profiles with chronic use, and low patient compliance with prescribed regimens. Dermatology market has begun to expand after the entry of new biologic agents in the treatment of psoriasis and the addition of improved reformulations of existing therapeutics in acne and rosacea.
