In the quest for healthy skin and bodies, we tend to find ourselves at a crossroads between two essential factors: daily sunscreen use and vitamin D absorption. Does wearing sunscreen every day prevent your body from producing essential vitamin D? Today, we will address this misconception, its origins, and why both sun protection and vitamin D from the sun are crucial for your well-being. So, let’s get started.

Where Does the Sunscreen and Vitamin D Myth Come From?

The belief that sunscreen use hampers vitamin D absorption stems from the notion that sunscreen blocks the sun's ultraviolet B (UVB) rays, which are responsible for triggering vitamin D synthesis in the skin. While this idea has some merit, it oversimplifies the complex relationship between sunscreen and vitamin D. Let’s see why.

Does Sunscreen Block Vitamin D Production By Blocking All UV Rays?

Actually, sunscreen does not completely block UV rays; in fact, some UVB gets through. Sunscreen acts as a protective barrier, significantly reducing the amount of UVB radiation that reaches your skin. However, even when wearing sunscreen, some UVB rays can penetrate and stimulate vitamin D production.

What Do Studies Say About Sunscreen & Vitamin D Deficiency?

Several studies have debunked the myth that daily sunscreen use specifically leads to vitamin D deficiency. The studies that raised this concern in the first place used unnatural sources of UV radiation. Cumulative research suggests that sunscreen, when used correctly, is not a significant hindrance to vitamin D absorption. This is, put simply, because:

1. Sunblock doesn’t 100% block UVB rays
2. In real life, sunblock application isn’t 100% coverage
3. In real life, we tend to go outside for short periods of time (5-30 minutes) without sunblock at all
4. It doesn't take long  for the skin to produce vitamin D – certainly not long enough to need to worry about sunscreen

How Much Sun Exposure Do You Need For Adequate Vitamin D?

The amount of sun exposure required to produce enough vitamin D varies depending on factors such as skin type, location, and time of day. Typically, exposing your hands, face, and arms to the sun for 10-30 minutes a few times a week is sufficient. This limited exposure can be achieved with or without sunscreen on, because, as we saw, sunblock still allows some UVB rays to penetrate.

What Are The Benefits Of Vitamin D From The Sun & Sunscreen?

Vitamin D plays a crucial role in maintaining overall health. It is essential for the absorption of calcium and phosphorus, promoting strong bones and teeth. It also supports a healthy immune system.

Sunscreen is an indispensable tool for protecting your skin from the harmful effects of UV radiation. Using sunscreen regularly helps mitigate these risks (specifically cancer) and is vital for maintaining healthy and youthful skin. 

In Summary, Don’t Ditch The Sunblock

As we’ve seen, it’s not worth the risk to ditch sunscreen from your routine. It’s still recommended to use sunscreen, since it doesn’t have as much of an impact on vitamin D levels as people tend to think. And, if you’re really concerned, a simple blood test is all that’s needed to assess your serum vitamin D levels.
