Acne that has been present for many years is mainly due to ongoing oil production, hormonal factors, or skin type, but it can still be controlled with the right treatment. Keep your skin clean, avoid oily products, and do not squeeze pimples, as this can worsen them and cause marks. A doctor can advise suitable creams or medicines based on your skin and severity, and treatment may need to be continued for some time for good results. With proper care and regular follow-up, acne can be managed effectively.

Acne for a month with red, blister-like pimples on the forehead is usually due to excess oil, blocked pores, or mild infection, and it often responds to basic care to prevent it from worsening. Keep the skin clean, avoid oily products, and do not squeeze pimples, as this can increase inflammation and leave marks. Simple care may help in mild cases, but if the pimples are painful, spreading, or not improving, a doctor can advise suitable treatment. Early care can help prevent scars and better control the condition.

Acne and boils on the forehead are usually caused by excess oil, blocked pores, sweat, or bacterial growth, and sometimes stress or hormonal changes can make it worse. Vitamin supplements like B12 or vitamin D may trigger breakouts in some people, but this is not very common and varies from person to person. Keep your skin clean, avoid oily products, and do not touch or squeeze the area, as it can worsen it. If the problem started after taking supplements or continues to worsen, consult your doctor so the exact cause can be identified and managed.
