Le s\u00e9l\u00e9nium est un oligo-\u00e9l\u00e9ment discret mais essentiel, dont les bienfaits sont multiples : antioxydant, anti-inflammatoire, protecteur et r\u00e9parateur, etc. (voir paragraphe ci-dessous d\u00e9di\u00e9 aux principales fonctions du s\u00e9l\u00e9nium). En cosm\u00e9tique, il permet d\u2019apporter une valeur ajout\u00e9e, notamment dans les soins anti-\u00e2ges, les produits apaisants ou encore les traitements capillaires. Son efficacit\u00e9 est accrue lorsqu\u2019il est utilis\u00e9 en synergie avec d\u2019autres actifs comme la vitamine C, E, les polyph\u00e9nols ou encore la niacinamide. Ces associations renforcent son pouvoir antioxydant qui est, indubitablement, son action phare. Il participe au fonctionnement de plusieurs enzymes cl\u00e9s protectrices de la peau (par exemple la glutathion peroxydase) qui neutralisent les radicaux libres responsables du vieillissement cutan\u00e9. <\/p>\n\n

Principales fonctions (liste non exhaustive)<\/h4>\n\n

Propri\u00e9t\u00e9s antioxydantes : <\/strong>ralentissement des rides et ridules, pr\u00e9vention du teint terne et du rel\u00e2chement cutan\u00e9, protection du collag\u00e8ne et de l\u2019\u00e9lastine, tout en veillant \u00e0 une meilleure r\u00e9sistance aux agressions environnementales (UV, pollution, stress, etc.) ;Protection et renforcement de la barri\u00e8re cutan\u00e9e : <\/strong>limitation de l\u2019oxydation des lipides qui composent la barri\u00e8re cutan\u00e9e afin de la maintenir intacte pour garantir une hydratation optimale ;Effets anti-inflammatoires : <\/strong>diminution des irritations, apaisement des rougeurs, soutien en cas d\u2019ecz\u00e9ma ou de rosac\u00e9e, action calmante en cas de peau fragile, stress\u00e9e ou expos\u00e9e \u00e0 des agressions ext\u00e9rieures ;Soutien la r\u00e9paration cellulaire : <\/strong>participation \u00e0 la r\u00e9paration de l\u2019ADN et protection des dommages cutan\u00e9s induits par les UV, la pollution ou des agressions ext\u00e9rieures. Favorisation du renouvellement cellulaire ; Effets sur l\u2019\u00e9clat et l\u2019uniformit\u00e9 du teint :<\/strong> r\u00e9duction du stress oxydatif et\/ou de l\u2019inflammation. Le teint retrouve de l\u2019\u00e9clat, il est plus lumineux et uniformis\u00e9. Diminution des taches pigmentaires li\u00e9es aux UV. <\/p>\n\n

Le s\u00e9l\u00e9nium dans les produits cosm\u00e9tiques<\/h4>\n\n

En cosm\u00e9tique, le s\u00e9l\u00e9nium peut \u00eatre int\u00e9gr\u00e9 sous diverses formes. On en retrouve ainsi dans des s\u00e9rums antioxydants (s\u00e9l\u00e9nium \u00e9l\u00e9mentaire ou d\u00e9riv\u00e9s antioxydants), des soins anti-\u00e2ges, des produits apaisants pour peaux sensibles ou fragilis\u00e9es, ou encore dans des brumes et eaux thermales. Le sulfure de s\u00e9l\u00e9nium est un agent fongique qui est surtout utilis\u00e9 dans les shampooings et lotions antipelliculaires. Il est strictement r\u00e9glement\u00e9 et r\u00e9serv\u00e9 aux produits \u00e0 rincer. <\/p>\n\n
