Salicylic acid and sulfur combination in topical form is used to treat patients who suffer from mild skin and scalp disorders, such as dandruff, acne, and seborrheic dermatitis.
Sulfer and salicylic acid belong to a group of chemicals called keratolytic agents. They work in combination by causing the patient’s skin to shed all the dead cells from the upper dermal layer. The medication increases the quantity of moisture contained in the skin and dissolves the protein that causes the cells to stick together. The overall effect makes shedding the dead cells easier, softens the upper dermis, and reduces dryness and scaling. Salicylic acid actually belongs to the same group of drugs as aspirin.
The medication comes in various forms including lotion, liquid, soap, cream, bar, shampoo, and ointment. You can buy salicylic acid and sulfur combination without a doctor’s prescription, over-the-counter at your local pharmacy or drug store.
In the US, salicylic acid and sulfur combination goes by the brand name, SAStid. In Canada, it is sold as Night Cast R and Fostex Cream.
