PRODUCT INTRODUCTION
description
Salicylic acid is an odorless white to light tan solid. Sinks and mixes slowly with water. (USCG, 1999)
Uses
Salicylic acid is a medicated topical gel, cream, lotion or solution. It treats many skin disorders, such as acne, dandruff, psoriasis, seborrheic dermatitis of the skin and scalp, calluses, corns, common warts, and plantar warts, depending on the dosage form and strength of the preparation.
Adverse Effects
Although salicylic acid is considered safe overall, it may cause skin irritation when first starting. It may also remove too much oil, resulting in dryness and potential irritation.
