..In the past decade, sunscreen products have undergone fundamental improvements, the most significant of which is the breadth of protection against UVA I...

..Lastly, we reviewed alternative agents, such as antioxidants, that can be used to supplement and augment photoprotection provided by sunscreens...

..There is no reliably effective treatment. We report the use of the 595-nm pulsed-dye laser (PDL) for the treatment of wounds healing by second intention and complicated by hypergranulation tissue after Mohs micrographic surgery...

..Many studies have examined the behavior patterns of the public on sunscreen use, but little is known regarding the level of knowledge the public has regarding sunscreen...

..High-resolution ultrasound is an adjunct diagnostic aid mainly for the early detection of lymph node metastasis. Applications and limitations of each technology are discussed...

..Adding antioxidants to UV filters in sunscreens is a novel photoprotective strategy. The topical application of antioxidants in sunscreen can potentially neutralize the UVA-induced free radicals...

..Currently in the United States, there is no regulation on testing and labeling of sunscreens for UVA protection. In August 2007, the Food and Drug Administration (FDA) addressed this issue in a proposed rule...

....

..In addition we reviewed the recent safety concerns surrounding these materials, specifically, percutaneous penetration of TiO(2) and ZnO nanoparticles through human skin and their potential to cause phototoxicity...

..Given this trend, it is clear why sunscreens invariably take center stage in any discussion regarding obtaining adequate photoprotection...

..Basal cell carcinomas (BCCs) can be diagnosed using different dermoscopic modalities...

..This review will discuss our current understanding of the mechanisms of free radical damage and evaluate the potential benefit of topical antioxidants in sunscreens and skin care products...

..The relationship between oral vitamin D supplementation and cutaneous photosynthesis is not well understood...

..We will highlight key considerations for clinicians when interpreting the results of antioxidant tests when evaluating commercial products containing antioxidants...

..Studies have demonstrated differences in colors and dermoscopic structures observed with polarized dermoscopes (PDs) and nonpolarized dermoscopes (NPDs)...

..We also review the literature on this subject...

..PBCC is a rare variant of nodular BCCs. Clinically, PBCCs mimic acrochordons. We recommend that the perineum, perianal, and genital areas should be included in the routine exam of patients with BCNS...

..However, a number of controversies have developed regarding their safety and efficacy. This review summarizes the relevant studies surrounding these controversies...

..Future photoprotection messages should shift from purely promoting knowledge to inspiring improvements in behavior with targeted strategies...

..Suspicion of sBCC was confirmed after visualization of dermoscopic structures consistent with sBCC. We highlight this case to encourage the use of dermoscopy in these patients for prompt diagnosis of BCCs...

..Serial cross-sectioning (bread-loafing) may result in false negative margin examination and higher local recurrence rates than Mohs micrographic surgery, which histologically evaluates the entire surgical margin...

..Architectural order/disorder is derived from current concepts regarding the biology of benign versus malignant melanocytic neoplasms...

..This statistic implies that 1) melanomas with subtle signs are missed as benign lesions, and 2) benign lesions are over diagnosed as melanomas, which lead to unnecessary biopsies...

..The combination of total cutaneous photography, total cutaneous examination, and dermoscopy were used in treating our patients. No MM 1 mm or greater in thickness developed during follow-up in either group...
