Whiteheads are closed non-inflammatory grade I type of acne and are often referred to as closed comedonal acne. Unlike blackheads, whiteheads are part of a closed pore. The blockage of pores can be caused during hormonal changes, menstruation, puberty, pregnancy, and menopause; though they can occur at any age.
Medications may produce excessive hormone levels that cause this type of acne. Whiteheads could be carried forward due to genetics. Comedonal acne are often seen around the face, chin, forehead, where pores are prone to clogging. Development of whiteheads is not limited to gender/age.
A combination of medications and lifestyle changes can gradually solve whiteheads. Oral and topical medicines (as prescribed) can help clear acne.
