Someone recomended betnovate c cream for my pimples, is this good?

Horrible choice: This is the powerful glucocorticoid betamethasone. It will suppress the inflammation for a moment, while allowing the bacteria to overgrow, inviting a serious infection, causing hyperplasia of the acne-producing glands, and risking atrophy of the area. Plus, you are using a prescription med inappropriately. Get some topical benzoyl peroxide & phone your physician.
