Acne vulgaris, also known as blackheads, is formed due to the accumulation of sebum secretions in the hair follicles.
Blackheads, also known as open pimples, are formed when sebum secretions that are partially expelled from the hair follicles combine with oxygen in the air to undergo an oxidative reaction and form a type of blackhead.
The main measure to prevent blackheads and pimples is to wash the facial skin in time, and for the obvious symptoms of blackheads and pimples, you can also use some medication that has the ability to dissolve the keratin (adapalene gel, benzoyl peroxide gel, etc.), and you can even utilize a low concentration of fruit acids to brush the acid treatment to improve the symptoms of blackheads.
In the process of preventing and treating blackheads, avoid spicy and stimulating foods, and if necessary, give medication under the guidance of a doctor.
