Acne scars are permanent marks or indentations on the skin that are left behind after healing of severe or prolonged acne breakouts. These scars can occur in various shapes and sizes, ranging from shallow depressions or slight discoloration to deep and noticeable pits.
暗瘡疤痕are caused by the body’s natural healing process, where the inflammation and tissue damage caused by acne can lead to the formation of scar tissue. These scars can be a source of physical and emotional discomfort for some people, and there are several treatment options available to help reduce their appearance.
Types of acne scarring and causes of it
There are several types of acne scarring, each with its own distinct characteristics and causes. Here are some of the most common types:
Ice Pick Scars
These are deep, narrow, and sharply defined scars that resemble the puncture of an ice pick. They are usually caused by severe acne and occur when inflamed pimples or cysts damage the skin’s collagen and elastin fibers.
Boxcar Scars
These 暗瘡印凹凸洞 are wider and shallower than ice pick scars, with sharply defined edges and a flat base. They are caused by similar damage to the skin’s collagen and elastin fibers, but are typically the result of less severe acne.
Rolling Scars
These scars have a wave-like appearance, with gentle slopes and valleys. They are caused by damage to the underlying subcutaneous tissue, which can pull the skin down and create the rolling effect.
Hypertrophic Scars
These are thickened raised scars that appear when your body produces collagen in excess during the healing period. They are more common on the chest, back, and shoulders, and can be caused by severe or prolonged acne.
Atrophic Scars
These are depressions or pits in the skin that occur when there is a loss of tissue during the healing process. They are often the result of severe or cystic acne, and can be further classified as ice pick, boxcar, or rolling scars.
