Scars are formed due to inflamed lesions, papules, or cysts. The inflamed lesions swell up and break open the follicle wall, then the body responds and tries to repair the damage. The infected material spilling out creates deeper lesions. If the repair is not smooth, it causes scar formation. One must avoid squeezing and popping pimples as it also increases the risk of getting acne scarring. Dr. Rohit Batra MD (Dermatology, Venereology & Leprology), is an expert skin doctor who provides the best acne scar treatment in Delhi at Dermaworld Skin Clinics.
