To prevent acne (pimples), it is essential to maintain good facial hygiene. Wash your face twice a day using a gentle cleanser to eliminate excess oil and dirt. Refrain from picking or squeezing pimples, as this may lead to infection and scarring. Opt for non-comedogenic skincare products, maintain a balanced diet, and stay well-hydrated by drinking plenty of water. Additionally, over-the-counter creams containing salicylic acid or benzoyl peroxide can be effective for managing breakouts. If your acne is severe or does not improve, see a dermatologist for appropriate treatment.
