Kaufman concluded that darker skin pigmentation is associated with lower serum 25-hydroxyvitamin D concentration. Serum vitamin D level also appears to be related to intake of vitamin D – rich foods and multivitamins containing vitamin D, but not self-reported level of sun exposure or use of sun protection.
Vitamin D is a group of fat-soluble secosteroids that are responsible for several important biological processes, including our skin health. In fact, several causes of skin pigmentation can be traced back to vitamin-D deficiency.
A number of factors can trigger an increase in melanin production, but the main ones are sun exposure, hormonal influences, age and skin injuries or inflammation. Sun exposure is the number one cause of hyperpigmentation as it's sunlight that triggers the production of melanin in the first place.
The hyperpigmentation related to vitamin B12 deficiency is more common in darker-skinned patients. Few other cases of skin hyperpigmentation due to vitamin B12 deficiency have been reported in the literature. The mechanism of hyperpigmentation is due to increased melanin synthesis rather than a defect in melanin.
Vitamin D deficiency is associated with the risk of psoriasis and atopic dermatitis, and several clinical/observational studies have suggested the beneficial effect of vitamin D in the therapy of these 2 inflammatory skin disorders.
Some emerging evidence suggests that vitamin D can help with the symptoms of acne for those who have a vitamin D deficiency. Exposure to sunlight is a significant source of vitamin D. People might also get vitamin D from supplements or creams. People with vitamin D deficiencies are more susceptible to acne.
Three of the best vitamins for lightening dark spots are vitamin C, vitamin B12, and vitamin E. Vitamin C helps your skin produce more collagen while inhibiting the formation of melanin. Vitamin B12 also promotes collagen formation while supporting the growth of new skin cells.
Some research has shown that a vitamin D deficiency may be connected with several skin conditions, including psoriasis and atopic dermatitis, the latter an allergic reaction that comes with an itchy, scaly rash, usually on your face, elbows, and knees.
Hyperpigmentation is an early and reversible sign of vitamin B 12 deficiency, which must be promptly recognised and corrected. The cause of B12 deficiency must be identified and additionally treated.
What does seem to be the general consensus though in answer to the question, does taking vitamin D help you tan, is that whilst it's probably unlikely that vitamin D supplements darken the skin, being exposed to sunlight helps us to manufacture vitamin D, and in this process, we may also get a tan.
But how do you flush vitamin D out of your system – and can you even do that? Yes, by ensuring you consume plenty of water. This will encourage urination, allowing your body to shed the excess vitamin D and calcium more quickly. Prescription diuretics like furosemide can also be helpful.

Many mucocutaneous findings, including hair and nail changes and hyperpigmentation, especially of the hands and feet, are associated with vitamin B12 deficiency [5]. Reversible skin and mucosal hyperpigmentation are the most commonly found skin manifestations of vitamin B12 deficiency [6].
Tranexamic acid has also found to inhibit tyrosinase activity to reduce hyperpigmentation. Tyrosinase is an enzyme that catalyzes the first step of melanin synthesis from the protein tyrosine. This mechanism of action of tranexamic acid leads to a slowed melanin synthesis and lightened hyperpigmentation.

High-dose vitamins B6 and B12 have also been linked to rosacea fulminans, a condition that looks like acne. Rosacea is marked by large red bumps and pustules that typically appear on the nose, chin, and/or cheeks.
You don't get enough vitamin D in your diet. You don't absorb enough vitamin D from food (a malabsorption problem) You don't get enough exposure to sunlight. Your liver or kidneys cannot convert vitamin D to its active form in the body.
