Acne, medically known as Acne Vulgaris, is a skin disease that involves the oil glands at the base of hair follicles. It commonly occurs during puberty when the sebaceous (oil) glands come to life - the glands are stimulated by male hormones produced by the adrenal glands of both males and females. Acne is not dangerous, but can leave skin scars. Human skin has pores (tiny holes) which connect to oil glands located under the skin. The glands are connected to the pores via follicles - small canals. These glands produce Sebum, an oily liquid. The sebum carries dead skin cells through the follicles to the surface of the skin. A small hair grows through the follicle out of the skin. Pimples grow when these follicles get blocked, resulting in an accumulation of oil under the skin.
Rolling Acne Scars
Rolling scars are common for individuals who have had patches of skin that have been afflicted by long-term inflammatory acne. They tend to become more pronounced as the skin ages and loses its original elasticity and fullness.
Because rolling scars have rounded, sloping borders, many of the available scar treatment techniques are capable of producing positive results
Raised Acne Scars
Hypertrophic and Keloid Scars - Commonly called hypertrophic or keloid scars, raised scars present a different problem than depressed scars. This is the only type of acne scar that is NOT suitable for derma rolling treatment. Hypertrophic scars are those in which excess scar tissue forms at the site of the injury, which presents as a raised region of fibrous and firm scar tissue.
Ice Pick Scars
Ice pick scars are deep, very narrow scars that extend into the dermis. The skin looks as if it has been pierced by an ice pick or sharp instrument. Ice pick scars seem to make a small, deep "hole" in the skin. Some may look like a large, open pore. Ice pick scars develop after an infection from a cyst or other deep inflamed blemish works its way to the surface. Skin tissue is destroyed, leaving a long column-like scar.
Boxcar scars are round or oval depressions with steep vertical sides. Wider than ice picks, boxcar scars give the skin a pitted appearance.
When an inflammatory breakout destroys collagen, tissue is lost. The skin over this area is left without support, and a depressed area is created. Boxcar scars may be superficial to severe, depending on the amount of tissue lost.
Derma rolling for acne scars:
The derma roller is the most effective way to build up the craters in your skin caused by acne scarring. Ice picks, boxcar & rolling acne scar will decreasingly fade away as these craters “fill up” with new and healthy skin cells.
