INTRODUCTION While the standardization of exploration with photoallergy tests or photopatch testing runs its course in Europe, we have carried out an epidemiological study about the current situation of photoallergy in our country. MATERIAL AND METHODS We have gathered the results of photopatch testing in seven hospital centres of Madrid, Cataluña, Galicia and Comunidad Valenciana during the ...

In recent years, exposure to ultraviolet (UV) radiation has been linked to a number of human health problems, including sunburn, skin cancer, premature aging of the skin, cataracts, and immune suppression (1–3). At the same time, evidence of aerosol-induced damage to the earth’s primary UV filter, the ozone layer, has increased (4 ), and skin cancer rates have risen to more than 900,000 cases p...

Sunscreens are known to protect against sunlight-induced erythema and sunburn, but their efficiency at protecting against skin cancer is still a matter of debate. Specifically, the capacity of sunscreens to prevent or reduce tissue and DNA damage has not been thoroughly investigated. The present study was undertaken to assess the ability of a chemical broad-spectrum sunscreen to protect human s...

Regarding the outdoor behavior of the Caucasian population, modern sunscreens should provide high and broad-spectrum ultraviolet protection in the ultraviolet B as well as in the ultraviolet A range and should be photochemically stable for ultraviolet doses, which can be expected in solar radiation. At present an assessment of the photostability of suncare products is not a general requirement ...

The photoprotective role of a family of compounds found in very different organisms is assessed by means of CASPT2//CASSCF computations. The potential use of these compounds in commercial applications in order to effectively dissipate light energy is explored.

Recent in vitro and animal studies have reported estrogen-like activity of chemicals used in sunscreen preparations. We investigated whether the three sunscreens benzophenone-3 (BP-3), octyl-methoxycinnamate (OMC), and 3-(4-methylbenzylidene) camphor (4-MBC) were absorbed and influenced endogenous reproductive hormone levels in humans after topical application. In this 2-wk single-blinded study...

The use of sunscreen products has been advocated by many health care practitioners as a means to reduce skin damage produced by ultraviolet radiation (UVR) from sunlight. There is a need to better understand the efficacy and safety of sunscreen products given this ongoing campaign encouraging their use. The approach used to establish sunscreen efficacy, sun protection factor (SPF), is a useful ...
