The goal of this observational study is to learn how an individual's skin type influences the wound healing process and scar formation in Chinese patients undergoing facial dermatologic surgery. The main questions it aims to answer are: How does skin type affect the quality of wound healing after facial surgery? How does skin type affect the formation of hypertrophic scars after facial surgery? Researchers will compare groups of patients with different skin types (classified by the Baumann Skin Type) to see if there are significant differences in their healing outcomes and scar characteristics. Participants in this study will: Receive standard facial dermatologic surgery as part of their clinical care. Have their skin type assessed preoperatively. Undergo scheduled postoperative follow-up assessments at 7 and 90 days to evaluate wound healing and scar development using standardized scales.

Patient and Observer Scar Assessment Scale version 2.0 (POSAS 2.0)
This scale comprises two separate subscales: the Observer Scar Assessment Scale (completed by the clinician) and the Patient Scar Assessment Scale (completed by the participant). The Observer Scale evaluates six items (vascularity, pigmentation, thickness, relief, pliability, and surface area) on a scale from 1 ("like normal skin") to 10 ("the worst scar imaginable"), with a total score ranging from 6 (best) to 60 (worst). The Patient Scale evaluates six items (pain, itching, color, stiffness, thickness, and irregularity) on a scale from 1 ("no, not at all") to 10 ("yes, very much"), with a total score also ranging from 6 (best) to 60 (worst). For both subscales, a higher score indicates a worse scar quality.
Time frame: 3-month follow-up
modified Stony Brook Scar Evaluation Scale (mSBSES)
Evaluations were independently performed by two clinicians who were blinded to group allocation. The scale comprises four items: scar width, height, color, and suture marks. Each item is scored from 0 to 2 points, where a score of 2 represents the closest resemblance to normal skin, and 0 represents the worst appearance. The total score ranges from 0 to 8, with a higher score indicating a more ideal scar appearance.
Time frame: 3-month follow-up
