Ask Dr. Lens: Vitamin D in Skincare

“I am proud of our pioneering use of vitamin D in skincare. Vitamin D has so many benefits for the skin, since it helps strengthen the skin barrier, build skin’s resilience and protect it against external factors and stress”
- Dr. Marko Lens

Here, Dr. Lens shares his knowledge on everything you need to know about vitamin D and it’s role in skincare.

Q: Why do you use provitamin D3 and what does it do?
DR. LENS: It protects the immune system of the skin because it promotes the production of antimicrobial peptides in the skin, and at the same time, is involved in the activity of Langerhans cells, which represent the immune system of the skin. Vitamin D also reinforces skin barrier function, and promotes keratinocyte (type of skin cell) proliferation, which is very important in the skin renewal process.

Q: What is the role of the skin's immune system?
DR. LENS: The skin’s immune system does the same as your overall immune system; it protects the skin against environmental factors that disturb and affect the skin negatively.

Q: How does vitamin D strengthen the skin barrier?
DR. LENS: Vitamin D s a lipid molecule and thus it replenishes lipids of the skin. It also enhances the production of structural proteins and ceramides which are essential for lipid barrier formation.

Q: Who should be using vitamin D topically?
DR. LENS: Anyone can use vitamin D topically. I always say that with the way we live our lives, our barrier function is always exposed to pollutants and so vitamin D can only help.

Q: Should one use vitamin D in their skincare all year around, or is it especially recommended for certain seasons?
DR. LENS: It can be used all year around. In the winter months the skin becomes drier, so vitamin D can be especially beneficial to replenish the moisture in the skin, but it really is a product to use all year round.

The vitamin D collection features a powerhouse trio of products, each of which has been supercharged with provitamin D3 to fortify, strengthen and soothe skin.
