The daily application of sunscreen would reduce skin aging by 24%. This information is very important since a third of the elderly suffer from pathological aging of the skin.
Spread on sunscreen every two hours, the board blooms again each year as summer approaches. This weekend, it’s time to put it on a layer. Not only because the first rays of the sun are finally making their appearance in France, but also because an Australian study has just shown that sunscreens actually slow down the aging of the skin.
To demonstrate this, the researchers recruited 903 people over the age of 55 whom they followed for four and a half years and divided them into four groups. 1er group had to apply SPF15 + sunscreen every morning and take 30mg of beta carotene on the 2ndth group also put on sunscreen daily but did not take any nutrients, the third group used sun protection as they wanted and took beta-carotain, and finally the last group just applied cream occasionally.
Result: At the end of the four and a half years of the experiment, a 24% decrease in skin aging was observed in people who had used sunscreen daily and who had repeated this application in the event of swimming or prolonged outings. Pr Adèle Green, author of this work, indicates that “very regular users have more elastic, less dry, less marked and less pigmented skin than people who do not protect themselves or little and this, whatever their age” . In contrast, there was no significant difference between the groups that had beta-carotene supplementation and the others. It should be noted that this independent work, published in the Annals of internal medicine, was funded by the Australian Council for Health and Medical Research.
These very clear results are particularly important at a time when more and more elderly people suffer from pathological aging of the skin. During the last French-speaking congress on the frailty of the elderly which was held last April, a French study showed that a third of the patients hospitalized in the geriatric departments of the Toulouse University Hospital suffered from dermatoporosis. This recent term defines the syndrome of chronic skin failure associated with advanced age, a large cumulative dose of solar radiation and the use of drugs against atopic dermatitis. According to Dr Jean-Hilaire Saurat of the University of Geneva, “with the increase in the number of elderly people, this disease is likely to become a public health problem”. He clarified that dermatoporosis can sometimes require hospitalization.
