A 2013 study concluded that the diligent, everyday application of sunscreen could slow or temporarily prevent the development of wrinkles and sagging skin.<ref name=wrinkles>{{cite journal | vauthors = Hughes MC, Williams GM, Baker P, Green AC | title = Sunscreen and prevention of skin aging: a randomized trial | journal = Annals of Internal Medicine | volume = 158 | issue = 11 | pages = 781–790 | date = June 2013 | pmid = 23732711 | doi = 10.7326/0003-4819-158-11-201306040-00002 | url = http://annals.org/article.aspx?articleid=1691732 | access-date = June 6, 2013 | url-status = live | s2cid = 12250745 | archive-url = https://web.archive.org/web/20150404204739/http://annals.org/article.aspx?articleid=1691732 | archive-date = April 4, 2015 | url-access = subscription }}</ref> The study involved 900 [[light skin|white]] people in Australia and required some of them to apply a broad-spectrum sunscreen every day for four and a half years. It found that people who did so had noticeably more resilient and smoother skin than those assigned to continue their usual practices.<ref name=wrinkles/> A study on 32 subjects showed that daily use of sunscreen (SPF 30) reversed [[photoaging]] of the skin within 12 weeks and the amelioration continued until the end of the investigation period of one year.<ref>{{cite journal | vauthors = Randhawa M, Wang S, Leyden JJ, Cula GO, Pagnoni A, Southall MD | title = Daily Use of a Facial Broad Spectrum Sunscreen Over One-Year Significantly Improves Clinical Evaluation of Photoaging | journal = Dermatologic Surgery | volume = 42 | issue = 12 | pages = 1354–1361 | date = December 2016 | pmid = 27749441 | doi = 10.1097/DSS.0000000000000879 | s2cid = 37092409 }}</ref> Sunscreen is inherently anti-ageing as the sun is the number one cause of premature ageing; it therefore may slow or temporarily prevent the development of wrinkles, dark spots, and sagging skin.
