Answer

Coal tar topical preparations have antipruritic and anti-inflammatory effects. [52] They work as disinfectants and astringents and help to correct abnormal keratinization by decreasing both epidermal proliferation and dermal infiltration. They are effective as second-line agents for subacute, chronic, and lichenified atopic dermatitis. Cosmetically acceptable preparations are available and include AquaTar, Estar, Fototar, PsoriGel, and Neutrogena T/Derm Tar Emollient. Tar shampoos, such as Neutrogena T-Gel, are effective for scalp involvement. Adverse effects may include folliculitis and photosensitivity.
