Vitamin D can effectively treat keloid scars, finds Study

Vitamin D plays an essential role in cell differentiation and proliferation as its slows the progression of tissue fibrosis by keloid fibroblasts and inhibit the synthesis of collagen in dermal fibrosis. Considering this, Menna Mamdouh, Dermatology and Venereology, Al‐Azhar University, Cairo, Egypt, and colleagues aimed to evaluate the efficacy of intralesional injection of vitamin D in the treatment of keloids, both clinically and ultrasonically.

For the purpose, 40 Egyptian patients with keloid scars were injected weekly with intralesional vitamin D with dose of 0.2 ml (200,000 IU) per 1 cm lesion. The keloid scars were evaluated with Vancouver Scar Scale (VSS) and by a high‐resolution ultrasound using B mode before and after treatment, the patients received 3 to 4 sessions. 

Key findings include:

"Intralesional vitamin D is an effective and safe method in treatment of keloid scars. Ultrasound is a useful method in assessing the improvement of keloids after treatment," wrote the authors.
