BACKGROUND Sunscreens are known to protect from sun damage; however, their effects on the reversal of photodamage have been minimally investigated. OBJECTIVE The aim of the prospective study was to evaluate the efficacy of a facial sun protection factor (SPF) 30 formulation for the improvement of photodamage during a 1-year use. METHODS Thirty-two subjects applied a broad spectrum photostab...
Three-photon wide-field depth-resolved excitation is used to overcome some of the limitations in conventional point-scanning two- and three-photon microscopy. Excitation of chromophores as diverse as channelrhodopsins and quantum dots is shown, and a penetration depth of more than 700 μm into fixed scattering brain tissue is achieved, approximately twice as deep as that achieved using two-photo...
BACKGROUND Photodamage describes skin changes such as fine and coarse wrinkles, roughness, freckles and pigmentation changes that occur as a result of prolonged exposure to the sun. Many treatments are available to reverse the damage, but it is unclear which work and at what cost in terms of unwanted side effects. OBJECTIVES To assess the effects of topically applied treatments, tablet treatm...
The search for novel photoprotective substances has become a challenge in cosmeceutical research. Streptomyces-derived compounds can serve as promising source of agents to formulate skin photoprotection products, such sunscreens. This study aimed identify specialized metabolites with the potential modulate UV-induced cellular damage by identifying multi-target-directed ligands. Using combinatio...
