For mild to moderate acne, dermatologists often suggest an acne face wash with bacteria-killing benzoyl peroxide (to minimize irritation, 3.5 percent strength should be your max if you have sensitive skin), along with a prescription topical antimicrobial such as clindamycin or erythromycin. If you rather go with a gentle face wash for sensitive skin, you can use that and apply a benzoyl peroxide acne spot treatment instead.
Hypertrophic scars are uncommon, and are characterized by increased collagen content after the abnormal healing response. They are described as firm and raised from the skin. Hypertrophic scars remain within the original margins of the wound, whereas keloid scars can form scar tissue outside of these borders. Keloid scars from acne occur more often in men and people with darker skin, and usually occur on the trunk of the body.
Acne removal: Your dermatologist may perform a procedure called “drainage and extraction” to remove a large acne cyst. This procedure helps when the cyst does not respond to medicine. It also helps ease the pain and the chance that the cyst will leave a scar. If you absolutely have to get rid of a cyst quickly, your dermatologist may inject the cyst with medicine.
