How to protect your skin without sacrificing vitamin D

We all know the sun helps our skin produce vitamin D, but when it comes to sunlight and skin health, balance is everything. While UVB rays are essential for stimulating vitamin D production in the skin, overexposure to the sun doesn’t boost your vitamin D levels further. In fact, it can do the opposite: damaging your skin’s ability to produce and use this vital nutrient.

According to findings published by the Linus Pauling Institute and supported by further dermatological research, too much UV exposure can actually break down vitamin D stores in the skin.¹ This degradation means prolonged time in the sun won’t necessarily increase your vitamin D levels. Instead, it may compromise them.

What’s more, excessive sun exposure causes oxidative stress, DNA damage, and inflammation - factors that disrupt the delicate mechanisms behind vitamin D synthesis and activation. The enzymes needed to convert vitamin D into its usable form can become less effective, while oxidative stress can damage vitamin D receptors themselves.^2,3 This receptor damage is significant: even if your body produces vitamin D, your skin may not be able to absorb or use it properly.

So what can be done to ensure you’re getting the right levels of protection and vitamin D?

A breakthrough in skincare science

Enter ASPA-Fernblock®, the next-generation, clinically proven photoprotection innovation from Cantabria Labs now being rolled out across the award-winning Heliocare 360° range. Its unique OptiD Effect helps maintain vitamin D activity in the skin - protecting it from UV damage without blocking the body’s natural vitamin D processes.

Dermatological research shows that ASPA-Fernblock® helps preserve vitamin D receptors in skin under oxidative stress, allowing it to continue absorbing and using vitamin D even after UV exposure.³ This means that while your skin is being shielded from harmful UVA, UVB and infrared-A rays, it’s also supported to maintain essential biological functions.

The OptiD Effect sets Heliocare 360° with ASPA-Fernblock® apart from traditional sunscreens. It delivers the best of both worlds: advanced antioxidant defence and UV protection, while helping your skin stay functional, resilient, and healthy.
