Most of the factors that interfere with the production of collagen in healing tissues are nutritional.Scurvy,for example,is caused by lack of ascorbic acid-one of the cofactors required for collagen formation by fibroblasts.The results of scurvy are poorly formed connective tissue and greatly impaired healing.
Vitamin D deficiency will not directly affect healing; ascorbic acid does.
Melanin deficiency will not directly affect healing; ascorbic acid does.
