(Read the blog here- Post-acne scar treatment).

In today's article, we will help to educate you further by understanding the difference between Microdermabrasion & Dermabrasion in acne scars.  


Dermabrasion can be considered as a cosmetic procedure that is performed under local or general anesthesia in which a specialized high-speed rotary brush or fraise-like instrument is used to "sand" the skin. This abrasive action improves your skin contour as a new layer of skin replaces the treated skin, resulting in a smoother, refreshed, and rejuvenated appearance.

Dermabrasion can improve acne scars and scars resulting from accidents or skin any other skin lesions. Dermabrasion does cause crusting of the skin and does require downtime. Super facial scars may be removed altogether and deeper scars may be reduced in depth. There is often a small pinpoint bleeding of the raw wound after the procedure that can be reduced with proper wound care.


Microdermabrasion, which is also known as “power peel”, involves using tiny crystals that are sprayed on the skin, which helps treat superficial skin problems like fine lines, dull skin, brown spots, mild acne scars, age spots, and sun-damaged layers of skin.

Rather than a high-speed brush, microdermabrasion uses aluminum oxide crystals that are passed with the help of a vacuum tube in order to exfoliate the overall surface skin. Only the very superficial cells of the skin are removed, so no additional wound is created. Unlike dermabrasion, microdermabrasion causes no bleeding and requires minimal or almost no downtime.

When the tip of the handpiece is placed on the surface of the skin and the system is activated, the handpiece gently pulls the skin in. The power line projects the aluminum oxide crystals onto the skin surface through one opening. These abrade the skin surface and the used crystals along with the epidermal debris and grime are collected by the tubings of the suction system through another opening housed in the tip of the same handpiece; thus establishing a close circuit loop of continuous flow and collection simultaneously.

Microdermabrasion vs Dermabrasion

Both dermabrasion and microdermabrasion are basically facial resurfacing techniques that mechanically ablate damaged skin to promote reepithelialization. Although the act of physical abrasion of the skin is common practice in both procedures, dermabrasion, and microdermabrasion use different instruments with different technical execution procedures. In dermabrasion, a handheld device that has a rotating wheel layered with wire brushes is used to peel away the layers of damaged skin, while in microdermabrasion, a mechanical handpiece that includes a pump to generates a stream of aluminum oxide or salt crystals with a handpiece and a vacuum tube.

Dermabrasion can be considered as a more intense version of microdermabrasion and forcibly removes deeper layers of skin. So while microdermabrasion only removes dead or dying skin, dermabrasion goes deeper and removes layers of the skin that are still viable (alive).

Unlike dermabrasion, microdermabrasion can be repeated at a short interval of time, is painless, and does not require any local anesthesia.
