SPF values only refer to UVB protection

SPF values only refer to UVB protection

Did you know that the Sun Protection Factor (SPF) only refers to UVB radiation protection? As a consequence if no UVA radiation protection is used, up to 50% of the UVA radiation is reaching your skin dermis (1). Although UVA radiation does not burn the skin, it is also involved in skin cancer as UVB … Continue reading SPF values only refer to UVB protection

Organic UV filters as hormonal dysruptors

  A study carried out by Strajhar et al., 2017 shows how octocrylene and methoxycinnamate dysrupt the molecule pathways required for steroid hormone synthesis in the adrenal cortex. The study relies on an improved method for detecting the effect of hormone dysrupting chemicals. Human cells from the adrenal cortex (H295R) were utilized in this work. … Continue reading Organic UV filters as hormonal dysruptors

Chemical UV filters might cause men infertility

Chemical UV filters might cause men infertility

A study demonstrated in 2016 that 13 out of 29 chemical UV filters mimic the Ca2+ signaling in human sperms by activating the progesterone pathway. This causes a Ca2+ imbalance in human sperm cells which directly affects its capacity to fertilize the egg. All of these filters are allowed in the EU and/or US and … Continue reading Chemical UV filters might cause men infertility
