Acne is a chronic inflammation of hair follicles and sebaceous glands, which usually occurs on the face, chest and back.
In adolescence, due to the increase of androgen level in the body, sebaceous glands secrete vigorously, which makes the skin oil increase, and the increased skin oil will block pores, resulting in the secretion in hair follicles not being discharged smoothly, forming fat particles, that is, acne.
After you get acne, don't squeeze it with your hands or stick it with a needle, because after squeezing it with your hands or sticking it with a needle, the fat particles in the acne will be squeezed out. After the fat particles are squeezed out, a small hole will be left, and the small hole will grow out, leaving a scar. And after squeezing acne with hands or pricking with needles, bacteria in hands, needles and external air dust will be brought into acne, resulting in secondary infection of acne. After acne infection, the chances of leaving scars will increase.
You can use sulfur soap to clean your skin, because sulfur soap is alkaline and skin oil is acidic. The use of alkaline sulfur soap can neutralize acidic skin oil.
In areas with acne, you can apply acne ointment. The acne will gradually disappear after application.
If it is acne with secondary infection, redness, swelling, pain and fever will appear after infection. Erythromycin ointment or mupirocin ointment can be used, but people who are allergic to penicillin cannot use mupirocin ointment. If the infection is serious, antibiotics should be taken orally or injected for systemic anti-inflammatory treatment.
