Study shows decline in indoor tanning among teens
The use of indoor tanning beds among high-school girls dropped from 25% in 2009 to 20% in 2013, according to a study in JAMA Dermatology. Researchers also noted a decline among high-school boys from nearly 7% to 5% during the same period. White girls remained the group most apt to opt for indoor tanning, though the percentage within that group dropped from 37% to 31%, researchers added. HealthDay News

Bony orbit depth may guide best filler injection technique
Finding the depth of the periosteum can help determine the best filler injection technique for the tear trough and the palpebromalar groove, according to a study in Dermatologic Surgery. A serial puncture technique was a better fit for patients with a skin-to-periosteum distance of less than 0.5 centimeters, while a bolus technique was a better match when the depth was greater than 0.5 centimeters.
