Acne and Acne Scars
Acne is a skin condition that occurs when the skin's hair follicles become plugged with oil and dead skin cells. It can cause whiteheads, blackheads, and pimples, usually appearing on the face, forehead, chest, upper back, and shoulders. Pimples and plugged, oily skin can lead to scarring. Acne is most common in teenagers, though it can affect people of all ages.
Acne scars develop when a breakout of acne penetrates the skin deeply and damages the tissues beneath it. It is important to know what type of scars you have before attempting to treat them. Each type of scar responds differently to treatment, and some treatments are better for particular types of scars than others.
Types of acne scars:
- Atrophic or depressed scars- These scars are most commonly found on the face. They are depressed scars that sit below the surface of the surrounding skin. They form when not enough collagen is made while the wound is healing. There are three types of atrophic scars: boxcar, icepick, and rolling.
- Hypertrophic of raised scars- These scars are raised above the surface of the surrounding skin. They form when too much collagen is made while the wound is healing.
