Would that be okay to use face wash containing salicylic acid in it for whiteheads prone skin?

Yes: Facial products containing salicylic acid are over-the-counter and sold in stores everywhere. They are often used to treat acne. Once a day face-washing with a salicylic acid product is ok, but washing too often or scrubbing too vigorously may lead to irritated, reddened facial skin. Acne is a hormonal problem that leads to certain bacteria growing in oil glands. Acne is not caused by dirty skin.
