Daily Sunscreen Use May Help Slow Signs of Aging
It is common advice to wear sunscreen outdoors to protect yourself from sun damage, but until now, there had not been many substantial scientific studies validating this idea. Dermatology Daily recently presented a round-up of major publications who reported on a large-scale study that was conducted involving participants living in Australia, where the population deals with intense sun exposure on a daily basis. The study consisted of 900 caucasians, ranging in age from 25 to 55. Most subjects were prone to sunburn and had fair skin. Volunteers were split into two randomly selected groups – one group was instructed to wear sunscreen every day, and the other group was told they could wear it whenever they wanted. After four and a half years, it was observed that those who were wearing sunscreen every day were 24% less likely to develop signs of premature aging related to sun exposure. It was concluded that all participants, regardless of age, were able to benefit from sunscreen use, preserving healthy skin.
The timing of the study’s release appropriately coincided with recent changes to sunscreen regulations in the United States by the Food and Drug Administration (FDA). The FDA is now requiring any sunscreen that is labeled as “broad-spectrum” to protect against both ultraviolet-B and ultraviolet-A rays. Ultraviolet-A rays penetrate more deeply, and may be more important in the development of skin cancers and early aging. Ultraviolet-B rays are the so-called “sunburn rays”, but also play a role in skin cancer formation and premature aging.
