Dose-dependent progressive sunscreens. A new strategy for photoprotection?

A new generation of UV filters has been developed that act by limiting the dose of radiation rather than by blocking a fraction of the solar irradiance on the skin surface. Such progressive sunscreens are based on the photochemical transformation of suitable precursors upon exposure to sunlight. Broadband sunscreens are thus generated "on demand", affording protection when, where, and to the ex...

A review of sunscreens and moisturizers compounds drived from cyanobacteria

One of the most important functions of the skin is to protect against various stressors. Environmental stimuli such as UV and environmental pollution increase reactive oxygen species and cause wrinkles and skin aging. Skin aging is associated with decreased collagen production and decreased activity of enzymes involved in collagen structure. Moisturizing chemicals increase the skin's ability to...

Screening of cyanobacteria and microalgae for their ability to synthesize silver nanoparticles with antibacterial activity

The aim of this study was to assess the ability of selected strains of cyanobacteria and microalgae to biosynthesize silver nanoparticles (Ag-NPs) by using two procedures; (i) suspending the live and washed biomass of microalgae and cyanobacteria into the AgNO3 solution and (ii) by adding AgNO3 into a cell-free culture liquid. Ag-NPs were biosynthesized by 14 out of 16 tested strains. In most o...
