The Latest Drugs and Small Molecule Inhibitors for Skin and Hair.

Biologic drugs, a novel class of agents engineered to target specific mediators of inflammation, and small-molecule inhibitors that penetrate the cell membrane to interact with targets inside a cell represent the cutting-edge of pharmacological biomedical therapeutics. Clinical studies have already demonstrated the effectiveness of this new generation of drugs in treating a variety of medical illnesses and conditions that were refractory to traditional treatments. This review aims to describe the latest available or currently in-development drugs, biologic agents, and small molecule inhibitors for treatment of psoriasis, rosacea, alopecia areata, and atopic dermatitis.
