What is Vitamin D?
Vitamin D is a fat-soluble antioxidant which aids the absorption of essential minerals into our body. “Our body doesn’t create vitamin D on its own, so we need to replenish this through sun exposure, diet and supplements,” Abigail tells us. What’s the difference between vitamin D from sunlight, vitamin D as a supplement, and topical vitamin D? Abigail explains: “when our skin is exposed to sunlight it turns the cholesterol in our skin into Vitamin D and stores it in the skin. As an internal form it’s essential for cell renewal, protection, repair and metabolism. As a topical it acts as a hydrating type of antioxidant similar to vitamin E. It can be anti-inflammatory, and good for skin barrier and repair,” Abigail explains.
Benefits of Vitamin D for Skin
According to Abigail, “all skin types can and will benefit from vitamin D skincare.” Just choose a formulation that works for you. If oily skin is your concern, a lightweight vitamin D cream might be best, whereas a vitamin D oil for skin - which Abigail tells us is often a more potent option - is preferred for normal or dry skin. And we mustn't forget the dream pairing of vitamin D and acne. “Used on its own, vitamin D isn’t a fix for acne, however when combined with a product that contains antibacterial qualities, vitamin D’s support of barrier function and anti-inflammatory effects can be effective on acne,” says Abigail.
Side Effects of Vitamin D
What do we need to be wary of when introducing vitamin D into our skincare routine? “Do not use vitamin D products alongside alpha-hydroxy acids (glycolic, lactic acid) or beta-hydroxy acid (salicylic acid), as the acidic pH will deactivate vitamin D and you won’t absorb the benefits,” warns Dr Miriam. But, beyond that, “there should be no side effects when using vitamin D skincare,” Abigail reassures us.
“The only thing to be wary of is that some formulations might be richer or oiler, so don’t overdo it if you have acne-prone skin,” Abigail adds. “Topical Vitamin D is a much safer option than sun exposure for the skin,” Dr Miriam expands, “but oral supplementation is still recommended to meet the daily requirement. Do take care with extreme oral supplementation however,” Dr Miriam advises, as “vitamin D is stored in the body’s fat cells, so too much can cause toxicity with increased calcium levels in the blood, resulting in nausea, vomiting, confusion, and in extreme cases, kidney failure.”
How To Use Vitamin D In Your Skincare Routine
“Vitamin D is a fat-soluble antioxidant, so when added to skincare it’s usually in an oil or cream formulation,” Abigail tells us. What’s the difference? “Generally, an oil will be stronger than a cream,” says Abigail. When it comes to application, “an oil applied in the evening after your night serum is probably the best way to add vitamin D into your skincare routine. I would go for an oil-based formula because vitamin D is fat-soluble,” Dr Miriam recommends. “Use this in the evenings after cleansing the skin and allow the vitamin D oil to absorb overnight. Your vitamin D can be stepped up to twice daily if tolerated,” she prescribes.
