TLDR The new A-design punch for hair restoration surgery may lead to smaller scars compared to other types.

The study compared tissue loss and scar size from different Follicular Unit Extraction (FUE) punches on 5 patients and found that the new A-design punch had the smallest final scar size after 1 month. Despite having the largest initial wound size (0.932 mm), the A-design punch's scar size decreased by 35.837% to 0.598 mm, outperforming the sharp, blunt, and serrated punches which decreased by 22.518%, 23.077%, and 20.665% respectively. The findings suggest that the A-design punch may offer an improvement in minimizing scarring in hair restoration surgery.
