Scars are usually disfiguring and lead to low self esteem. Severe acne or a delay in treatment is the most common cause of post acne scarring.
The scars present in three different ways:
Atrophic: These are usually depressed scars and can present as:
• Ice pick or V-shaped scars which are narrow and deep scars.
• Rolling or M-shaped scars, they are shallow, superficial and have an undulating appearance.
• Box scars maybe shallow or deep, with vertical edges and are well defined.
• Small scars close to the hair follicles are known as perifollicular elastolysis are also present
Hypertrophic scars: These are raised reddish-purplish firm scars due to overgrowth of scar tissue and usually present around the jaw line. Keloid formation may occur too.
