New Study Shows Benefits Of Sunscreen

Need a reason beyond common sense and research performed on hairless mice to confirm that sunscreen is good for your skin? Well, now you have it. The Queensland Institute of Medical Research in Australia performed a study with SPF15+ to confirm the positive effects of this summer staple.

The study used a sample size of 903 adults between the ages of 25 and 55. Some were given directions telling them to apply SPF15+ sunscreen everyday on their face, hands, and arms, while others were left too choose how frequently they wanted to cover their exposed skin with the protective ointment.

Unsurprisingly, the adults who put on sunscreen everyday fared much better in the wrinkle department. Silicone molds taken from the backs of participants’ hands revealed that unprotected, sun-exposed skin will make for a more crinkly epidermis.

Again, this should not come as too much of a shock. Neither should the fact that “broad spectrum” sunscreen, protecting against both ultraviolet B and A rays, proves more effective than its less comprehensive counterparts. And, as Dr. Thomas Ruenger told NBC News, “The sunscreen has to be applied thick and in all areas to be effective,” citing SPF 20 and 30 as the way to go.

Before this ground-breaking study, the only scientific information we had to go on to confirm our suspicions about the positive correlation between sunscreen usage and good skin were studies performed on hairless mice. The Journal of Investigative Dermatology put out the study, Prevention of Ultraviolet Damage to the Dermis of Hairless Mice by Sunscreens (Kligman et al., 1981), showing that hairless mice exposed to sunlamps without sunscreen suffered from much greater skin damage than did their protected counterparts.

Good thing researchers in Australia decided to give us something else to go on.
