Want to smooth out your wrinkles, erase scars and sunspots, and look years younger? Millions of Americans a year turn to lasers and prescription drugs to rejuvenate their skin, but exactly how that rejuvenation works has never been fully explained. Now, Johns Hopkins researchers have discovered that laser treatments and the drug retinoic acid share a common molecular pathway. Moreover, that pathway — which lets skin cells sense loose RNA molecules — is also turned up in mice when they regenerate hair follicles. Results are described in the June 26 issue of Nature Communications.

Millions of people worldwide have vitiligo, a condition that causes the skin to lose its natural color, resulting in patches of light skin. Although the white or light patches do not typically cause other symptoms, the condition can cause low self-esteem and depression in patients—of whom nearly half develop vitiligo before the age of 21. Although there is no cure for vitiligo, dermatologists from the American Academy of Dermatology say there is a lot patients can do at home to make vitiligo less visible and help prevent the condition from spreading.

Facial bones in black adults maintain higher mineral density as they age than other races, resulting in fewer changes to their facial structure, a Rutgers study finds. The study, published in JAMA Facial Plastic Surgery, is the first to document how facial bones change as black adults age. The findings suggest significant differences in how facial bones age across races, which can affect how plastic surgeons approach facial rejuvenation. About 16 percent of black adults seek cosmetic procedures — double that of whites.

“Recent accounts of the Food and Drug Administration’s proposed sunscreen rule incorrectly suggest that many sunscreens currently on the market do not meet safety requirements of the FDA. In fact, only two ingredients were proposed to be unsafe — PABA and trolamine salicylate — and these are no longer available in the U.S. The American Academy of Dermatology is reminding the public that sunscreen remains an important way to protect yourself from the sun’s harmful ultraviolet rays. Scientific evidence supports the benefits of sunscreen to prevent sunburn and reduce the risk of skin cancer, the most common cancer in the United States.
