Acne scars are the result of the healing process of acne prone skin.
Acne scars are due to the untimely treatment of acne. Inflammatory acne scars occur when a pore or hair follicle fills with sebum, dead skin cells and bacteria.
The pore swells and causes a rupture in its wall.
If this rupture occurs near the skin, the healing does not leave a significant acne scar.
But if the rupture occurs in the background, then the skin is filled with inflammatory elements and bacteria destroying the healthy skin, leaving behind large acne scars.
The areas where acne scars appear are basically the face, back and chest. Acne scars can also occur on the nates.
