Coaltar S Lotion is a medicated topical solution used for the management of chronic skin conditions such as psoriasis, seborrheic dermatitis, and stubborn dandruff. It works through a synergistic combination of Coal Tar and Salicylic Acid. The coal tar slows down the rapid overproduction of skin cells and reduces inflammation, while the salicylic acid acts as a keratolytic agent to exfoliate dead scales and crusts. Together, they provide rapid relief from redness, swelling, and persistent itching.
