The short explanation
Sunscreen in everyday real-life use is unlikely to be the main reason for low vitamin D. In practice, most people do not apply enough sunscreen to block all the UVB light that the skin uses to make vitamin D, and studies have not shown that regular sunscreen use causes vitamin D deficiency in most people. Low vitamin D is very common in India despite plenty of sunshine, because of indoor lifestyles, covering clothing, pollution, darker skin needing more sun exposure, and diets low in vitamin D. If your level is already low, the safer approach is to discuss treatment with your doctor rather than skipping sun protection, especially if you have pigmentation or melasma.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Your doctor may suggest dietary sources, supplements or some sensible, short sun exposure based on your situation.
- Sun protection remains important for preventing pigmentation, tanning and skin ageing in Indian skin.
- Causes of low vitamin D such as absorption problems, kidney or liver disease may also be considered.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you why your vitamin D is low or how to treat it. Your doctor will advise based on your level and history.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How low is my vitamin D, and how should it be treated?
- Is it okay to keep using sunscreen?
- Should I get any sun exposure, and how much is sensible?
- When should my level be rechecked?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
