Dermaabrasion is a surgical skin-resurfacing technique that employs mechanical abrasion to remove the epidermis and superficial dermis, stimulating controlled wound healing and collagen remodeling. This procedure utilizes specialized rotary instruments with abrasive heads operating at high speeds to precisely excavate damaged skin layers.

The mechanical ablation creates a uniform wound depth of 0.1 to 0.5 millimeters, depending on the targeted pathology. Post-procedure healing involves re-epithelialization from surrounding epidermal appendages and deeper follicular structures, typically completing within 7-10 days. The neocollagenesis phase extends over several months, resulting in improved skin texture and appearance.

This intervention addresses various cutaneous conditions including acne scarring, photoaging, rhinophyma, and traumatic scars. The procedure requires local anesthesia or conscious sedation, with careful consideration of Fitzpatrick skin types to minimize post-inflammatory hyperpigmentation risks. Modern dermaabrasion techniques incorporate cryogenic cooling systems to enhance precision and reduce thermal injury to surrounding tissues.
