Abstract
background: Motor‐driven dermabrasion or deeper chemosurgical peeling improves photodamaged facial skin. However, these procedures each pose disadvantages that we felt could be largely ameliorated by combining manual dermasanding with low strength trichloroacetic acid peeling.objective: To evaluate the effectiveness, safety, and reproducibility of a technique combining manual dermasanding and light peeling in treating actinically injured facial skin.methods: Manual abrasion with moistened silicone‐carbide sandpaper followed by application of a 25% trichloro‐acetic acid solution was performed on over 300 patients followed as long as 7 years.results: Improvement was uniformly noted in luster, brightness, dyschromia, and rhytids. The procedure was easily mastered and results were reproducible. Postoperative pigmentary problems and scarring were extremely rare.conclusions: The technique demands minimal skill and experience, while providing pleasing results. There is no splatter or sharp lines of demarcation, and results suggest distinct advantages over motor‐driven dermabrasion or deep peeling procedures.
