Is Selen useful for Haut?

Selenium is an essential trace element with antioxidant properties, protecting skin via glutathione peroxidases against oxidative stress. Observational studies suggest benefits for certain skin conditions like acne, psoriasis, or UV-induced photoaging, but evidence is moderate. Randomized controlled trials show mixed results, and no clear benefit exists for well-nourished individuals. MyBody-X does not offer a specific selenium test; blood or hair analysis can assess status but is not routinely recommended. High selenium intake can cause toxicity (selenosis). Therefore, avoid self-supplementation with high doses; consult a doctor for skin issues and consider supplementation only after confirmed deficiency. Overall, the evidence for selenium improving skin health in the general population is limited.
