Concerns over vitamin D deficiency, particularly in children, have been linked in recent years to our growing awareness of the need to use of suncream.
Cases of the bone condition rickets, which is caused by lack of vitamin D, have increased fourfold at the same time as use of suncream has increased.
Now, a study from King’s College London, seems to suggest that we can actually make vitamin D even when we’re wearing suncream.
Antony Young, a professor at St John’s Institute of Dermatology, King’s College London, tested 79 men and women going on holiday to Tenerife.
Although Professor Young conceded that many people do not use enough suncream to get maximum protection, he showed one group how to apply it properly and found, according to the Daily Mail, even those “slathered” in suncream had increased vitamin D and no sunburn.
Those who didn’t properly apply suncream had a bigger increase in vitamin D but also got sunburnt.
Vitamin D is repsonsible for strong bones and has been linked to heart health. We obtain 90 per cent of our vitamin D from sun exposure and 10 per cent from what we eat.
Suncreams filter out UVB, which causes sunburn but also stimulates our production of vitamin D.
Professor Young believes his research shows that some UV can get through suncream.
