No, wearing sunscreen does not leave you vitamin D deficient...
“Ninety-five per cent of the solar UV spectrum is UVA [which are the rays that are ever-present, even on cloudy days], but SPF only measures protection from UVB. UVB is the direct, visible damage [so burning], but UVA is responsible for the more concerning damage, such as immunosuppression, skin cancer and premature skin ageing.” Make sure you choose an SPF that is labelled “broad spectrum” to ensure that what you’re applying also protects against UVA.
“The difference between SPF 30 and SPF 50 is only one per cent in terms of UVB protection level , but the key thing is that higher SPF will protect skin for longer. This wouldn’t be significant if people applied sunscreen every two hours as they should, but the biggest issue with sunscreen is compliance.” If you do forget to reapply your sunscreen, make sure you always use factor 50 as a rule.
