Scar formation after the most minor skin injury is often inevitable. Following cutaneous injury, there are important implications for patients with Asian skin types due to the genetic propensity for abnormal scar formation and hyperpigmentation in the pigmented skin.1 Therefore, prevention of abnormal skin scarring is considered paramount in these patients. In addition, these patients have a greater genetic susceptibility for hypertrophic and keloid scar formation in pigmented skin.2 Interestingly, there are some significant structural and physiological differences noted between Asian and Caucasian skin (Figure 1) with regard to structure and process of wound healing and scar formation.1,2 Asian skin has a thicker dermis than Caucasian skin of the same anatomical site, and a higher collagen density, which can lead to an increased fibroproliferative response during healing.1 Furthermore…
