Acne scar is a consequence of inflamed acne that damages and destroys the collagen and tissue around it leading to a production of fibrous tissue particularly common in nodulocystic acne, acne conglobata and acne fulminans. Acne scar may also be a long-term consequence.
Types of acne scar
- Atrophic scars – atrophic scars is the most common type of acne scars, are caused by destruction and loss of collagen in the dermis and present as indentations in the skin.
- Ice pick scars – ice pick scars usually narrow (<2 mm), deep, sharply demarcated tracts extend into the deep skin.
- Rolling scars – rolling scars usually wide (4 to 5 mm) and more shallow than ice pick scars.
- Boxcar scars – boxcar scars are wider at the base than ice pick scars and do not taper.
- Hypertrophic scars and keloids
Treatment for acne scar
- Treatment of redness within scars by pulse dye laser (V beam), Low level laser therapy (LLLT)/Phototherapy®
- Chemical reconstruction of skin scars technique (CROSS technique) Subcision
Step 2: A collagen remodeling procedure
- Non ablative fractional laser resurfacing such as fractional radiofrequency (EndyMed®)
- Chemical peels
- Skin needling
Step 3: Additional treatments to augment the results of the collagen remodeling procedure (eg, dermal filler)
