Salicylic acid ointment what is it use for?
Salicylic acid cream is any type of cream or lotion that contains salicylic acid as an active ingredient. Salicylic acid is used for the treatment of skin conditions, most commonly acne, psoriasis, and warts. The percentage of salicylic acid found in the salicylic acid cream generally determines what the cream is used for. When applied to the skin, the salicylic acid will help to soften thickened skin and slough off dead skin cells; this will reveal new, fresher skin underneath and allow other medicines to better penetrate the skin. It also helps to prevent whiteheads and blackheads from forming. Salicylic acid cream is often used on the face as an acne treatment. It should be used regularly for it to work most effectively; the product will not work as well if it is simply applied to a blackhead or blemish after one already exists. The creams that contain salicylic acid tend to work best as a preventative measure for acne. Some people find they have a sensitivity to salicylic acid cream; in that case, an acne cream that contains benzoyl peroxide is another option. Both of these products are used regularly for the treatment of acne, and some people find that one will simply work better than the other.
