Many people use various products to maintain healthy skin, and sunscreen has now become an essential part of most skincare routines. Applying sunscreen before going out in the sun is widely recommended
to reduce the risk of tanning, dark spots, and skin cancer caused by sun exposure.
However, the sun’s ultraviolet rays also help the body produce vitamin D, which has led some to question whether using sunscreen daily might cause a deficiency.
According to a report by Harvard Health, vitamin D is produced when the sun’s UVB rays interact with the skin, converting cholesterol into vitamin D. Since sunscreen blocks these rays, it is believed that it could potentially interfere with vitamin D production.
Reality Check: Sunscreen And Vitamin D Levels
In practice, most people do not apply sunscreen perfectly or in sufficient amounts to completely block UVB rays. Additionally, many individuals do not use sunscreen every day. As a result, sunscreen usage does not significantly affect vitamin D levels.
An Australian study confirmed that occasional use of sunscreen does not reduce vitamin D in the body.
Other Causes Of Vitamin D Deficiency
Vitamin D deficiency can arise from numerous factors beyond sunscreen, including:
- Staying indoors excessively
- Lack of exposure to morning sunlight
- Pollution
- Darker skin tones
- Ageing
- Insufficient vitamin D in the diet
Even individuals who do not use sunscreen can still experience vitamin D deficiency.
Expert Advice On Sun Protection
Experts stress the importance of using sunscreen, particularly when spending long periods outdoors or in strong sunlight, to prevent skin damage.
Using sunscreen does not directly lead to vitamin D deficiency.
Maintaining Adequate Vitamin D
To ensure sufficient vitamin D while protecting your skin:
- Spend some time in morning sunlight
- Include vitamin D-rich foods in your diet
- Take supplements if recommended by a doctor
Vitamin D is vital for overall health, and it is essential to balance sun protection with strategies to maintain adequate levels.
