Blackhead closures are also known as blackhead pimples, and treatments include medication, fruit acid resurfacing, and phototherapy. Blackheads and pimples are related to sebum secretion and Propionibacterium acnes reproduction. Pimples are formed when sebum and keratin plugs accumulate at the mouth of hair follicles. 1. Drugs: You can choose drugs to control abnormal keratinization and inhibit bacteria under doctor’s guidance, such as topical retinoic acid cream, benzoyl peroxide, etc., to improve the situation of blackheads and closed mouths. 2. Fruit Acid Resurfacing: High concentration of fruit acid brushed on the skin surface helps to dissolve the lipids clogged in the pores and helps to exfoliate the keratin, so as to achieve the effect of removing blackheads, but it needs to go through several treatments. 3. Photoelectric treatment: Laser, intense pulsed light and other treatments can use light and heat energy to act on sebaceous glands and inhibit their secretion, thus improving blackheads and pimples. Blackhead acne patients need to go to a regular hospital, face to face with the doctor, follow the doctor’s instructions for treatment, do not self-medication.
