Long-term pimple-prone skin is often due to excess oil, clogged pores, or hormonal factors, but it can be managed with consistent care. Keep your face clean with a gentle face wash, avoid oily or heavy products, and do not touch or squeeze pimples, as it can worsen them. Maintain a healthy diet, drink enough water, and manage stress as it can trigger breakouts. If acne is frequent or severe, a doctor can suggest suitable creams or medicines to control it effectively.
