Acne that has been present for many years is usually due to ongoing factors like excess oil production, clogged pores, bacteria, or hormonal influences. A consistent skincare routine is essential: use a gentle face wash twice daily, a non-comedogenic moisturiser, and sunscreen during the day. However, long-standing acne often needs medical treatment, so it is best to consult a dermatologist. They may prescribe creams containing retinoids or benzoyl peroxide, antibiotics if needed, or oral medicines for better control, depending on the severity. Avoid picking or squeezing pimples, as this can lead to scars. With the right treatment and regular follow-up, acne can be well controlled and future breakouts and marks can be reduced.
