Protection from excessive UV exposure is an important step in preventing skin cancer and photoaging. Motivated by the anti-aging benefits associated with photoprotection, most daily facial cream products (day creams) include UV filters. These products display the sun protection factor (SPF) on the label and claim to have broad-spectrum UV-B and UV-A coverage. Currently, there is no regulatory guideline on the testing and labeling of UV-A protection in sunscreens, and likewise, the degree of UV-A protection in these day creams is unknown. In this study, we report the estimated long-range UV-A1 (340 to 400 nm) protection in popular day creams.

Methods

Twenty-nine facial day creams with claims of broad-spectrum UV coverage were selected on the basis of their sales volume reported on the Web site www.amazon.com. The UV-A protection is estimated based on the concentration and types of . . . [Full Text of this Article]

To our knowledge, there has been no formal statistical evaluation of the trends of nasal tip management in rhinoplasty. Our first objective was to evaluate the changing trends in septorhinoplasty techniques for nasal tip contouring, within a single-surgeon, private facial plastic surgery practice. Our second goal was to determine if this change in techniques has led to improvement in outcomes.

We performed a retrospective medical chart review consisting of 2 groups of 50 consecutive patients who had undergone rhinoplasty. The 2 groups spanned a 10-year period, one from 1999 and the other from 2008. The study took place at a private facial plastic surgery practice with a focus on rhinoplasty, recognized as a center for revision rhinoplasty referral, in a major metropolitan area. Data collection included patient demographics and types of tip-plasty maneuvers performed. These techniques were categorized as either (1) reductive maneuvers or (2) stabilizing and strengthening maneuvers. The …
