Quizplus · Accepted Answer

Vitamin D is responsible for regulating melanin production in the skin, which in turn affects skin tone. Vitamin B9, also known as folic acid, works in conjunction with vitamin D to regulate melanin production. A deficiency in either vitamin can lead to hypopigmentation (lightening of the skin) or hyperpigmentation (darkening of the skin). B2, B6, B12, and folic acid are all involved in the metabolism of melanin, but do not have as significant an impact on skin tone as vitamins D and B9.
