3 Reasons Sunscreen’s Effect on Vitamin D Isn’t Worth Worrying About
Sunscreen blocks UVB rays, but most people don’t apply it perfectly. Missed spots and incidental sun exposure throughout the day usually leave enough UVB for your skin to maintain decent vitamin D levels.
The real risk is the opposite: skipping sunscreen because of vitamin D fears leads to sunburn, premature aging, and skin cancer. These are far more concrete and dangerous than a theoretical vitamin D deficiency.
Most vitamin D deficiency is caused by latitude, time indoors, and diet—not sunscreen use. If you’re worried, get your levels checked and take a supplement if needed. It’s cheaper than treating skin cancer.
