Microdermabrasion to get rid of acne scars and other types of blemishes on the skin is one of the oldest forms of skin rejuvenation used in modern medicine. While microdermabrasion refers to a very superficial procedure that is generally painless, other types of abrasion techniques that help get rid of acne scars can be effective. Microdermabrasion can help treat some types of acne, as well, before it develops into a worse blemish that may ultimately produce a scar.
Dermal sanding (dermasanding) and motorized dermal abrasion (motorized dermabrasion) work on deeper layers of the skin and are therefore more effective at helping to get rid of acne scars than superficial microdermabrasion in some cases.
How Dermabrasion Helps to Get Rid of Acne Scars
Acne scars form when damage to the surface of the skin or deep within the pore triggers the body’s healing response. Collagen proteins are sent to the area where the damage has occurred and fills in any gaps in the healthy tissue. The collagen proteins used by the body to heal damaged skin tissue is the same type of tissue that all skin is made of, with one primary difference: the way the fibers connect.
Scar tissues grow in one direction, while normal skin tissues are formed through connections that resemble basket weaving. This critical difference in the way the tissue connects means that scar tissue is more obvious on otherwise healthy skin. Dermal abrasion procedures helps to get rid of the acne scars by causing the skin to grow in a more organized fashion, therefore reducing the appearance of scars.
How it Works:
All types of dermal abrasion work the same way: by removing a layer of the skin so that new tissue can form in its place. Acne scars may develop at varying depths, so abrasion techniques that address issues at the proper depth are important. To get rid of acne scars with abrasion techniques, doctors will typically choose from one of the following procedures.
- Microdermabrasion – A superficial sanding of the top layer of skin, generally using crystals that are projected at the skin at high speeds. They are immediately vacuumed away and do not remain on the skin following the procedure. This type of treatment is generally painless and leaves little effect on the skin, though many people can feel the difference in their skin; it is not always a visible change.
- Dermasanding – This type of treatment gets rid of acne scars by exfoliating the skin at a deeper layer in the dermis. A doctor uses a special type of sandpaper to remove layers of skin and promoting the body to create new skin in that area. It can take some time for the skin to heal and a topical anesthetic may be used to help control pain.
- Motorized Dermabrasion – Similar to dermasanding, this type of treatment employs a motorized tool with a brush of diamond-dusted tip affixed to remove even deeper layers of skin. As the most invasive way to get rid of acne scars through abrasion, patients need to go under anesthesia to control pain and face months of healing following the procedure.
