Atrophic scars are the most common type of acne scars and occur due to a loss of tissue. They are characterized by indents or depressions in the skin.
1. Ice Pick Scars
Description: Ice pick scars are narrow, V-shaped scars that extend deep into the skin, resembling small but deep holes.
Causes: These scars form when inflamed blemishes work their way deep into the skin, destroying tissue. The skin’s natural healing process doesn’t replace this lost tissue.
TREATMENT
Dermabrasion: This surgical treatment can smooth out the appearance of ice pick scars by removing the top layers of skin.
Chemical Peels: Deep peels can reach deeper into the skin to encourage regeneration.
Punch Excision: A minor surgical procedure that involves cutting out the scar and closing the wound with stitches for a smoother appearance.
2. Boxcar Scars
Description: Boxcar scars are broad, box-like depressions with sharply defined edges.
Causes: Caused by widespread acne, such as cystic acne, these scars form when an outbreak destroys collagen, leaving a square-shaped depression.
TREATMENT
Microneedling: This method involves using fine needles to prick the skin, promoting collagen production and skin renewal.
Laser Therapy: Fractionated laser treatments can target precise areas, improving contour and texture.
Dermal Fillers: Temporary fillers can lift depressed scars to the level of surrounding skin.
3. Rolling Scars
Description: Rolling scars are wide depressions with sloping edges, giving the skin a wave-like appearance.
Causes: Caused by bands of scar tissue that develop under the skin, rolling scars occur when fibrous bands pull down the epidermis.
TREATMENT
Subcision: This procedure uses a needle to break up scar tissue beneath the skin, which can elevate the depressions.
Radiofrequency Microneedling: Combines microneedling with radiofrequency energy to improve collagen production and skin tightening.
Laser Resurfacing: Targets the top layers of skin to smooth out its texture.
