Pitted scars, also known as atrophic scars, can occur after surgical mole excision due to a few potential reasons: Depth of Excision: If the mole was excised deeply to ensure complete removal, it might have affected the underlying tissue, leading to a depression in the skin as it heals. Healing Process: Individual healing responses vary. Some people may develop pitted scars due to a lack of collagen production during the healing process, which is essential for rebuilding the skin's structure. Suture Technique and Timing: While you mentioned the sutures were removed after five days, the technique used and how the skin was closed can also influence scar formation. If the wound edges were not perfectly aligned or if there was tension on the wound, it might result in a pitted appearance. Location and Skin Type: Facial skin is delicate and may react differently compared to other areas. Additionally, factors like skin type and genetic predisposition can influence scar formation. Infection or Inflammation: Any infection or significant inflammation during the healing process can also contribute to abnormal scar formation. To improve the appearance of pitted scars, treatments such as laser therapy, microneedling, or dermal fillers might be considered. Consulting with a dermatologist or a plastic surgeon can provide you with options tailored to your specific situation.
