Error. La radiaci\u00f3 UV no agafa vacances a l’hivern, no desapareix quan hi ha n\u00favols i no t’avisa quan est\u00e0 fent mal.
\n<\/p>\n
Segons l’Organitzaci\u00f3 Mundial de la Salut, el 80% de la radiaci\u00f3 UV penetra a trav\u00e9s dels n\u00favols. En dies ennuvolats, l’exposici\u00f3 continua sent significativa encara que no se senti la calor del sol.<\/p>\n

El que el UVA fa i no notes<\/h3>\n

Existeixen dos tipus de radiaci\u00f3 ultraviolada que afecten la pell: el UVB, responsable de les cremades (m\u00e9s intens a l’estiu), i el UVA, que penetra m\u00e9s profund i est\u00e0 present amb la mateixa intensitat durant tot l’any. El UVA \u00e9s el responsable del fotoenvelliment: arrugues, p\u00e8rdua de fermesa i taques.
\nUn estudi publicat a The Journal of Investigative Dermatology<\/em> va demostrar que el dany acumulat per UVA \u00e9s responsable del 90% dels signes visibles d’envelliment cutani. El mat\u00eds important: aquest dany \u00e9s acumulatiu. Cada dia sense protecci\u00f3 suma.
\n<\/p>\n

El 90% dels signes visibles de l’envelliment cutani (arrugues, taques, p\u00e8rdua d’elasticitat) s’atribueixen a l’exposici\u00f3 solar acumulada al llarg dels anys, no a factors gen\u00e8tics.<\/p>\n

Com triar un fotoprotector que funcioni de veritat<\/h3>\n

No tots els fotoprotectors s\u00f3n iguals. Hi ha tres factors clau que mirar m\u00e9s enll\u00e0 del n\u00famero de SPF:<\/p>\n

    \n
  • Filtres d’ampli espectre:<\/strong> que bloquegin tant UVA com UVB. Busca a l’env\u00e0s \u00abbroad spectrum\u00bb o el s\u00edmbol UVA en cercle segons normativa europea.<\/li>\n
  • Textura adaptada a la teva pell:<\/strong> una pell mixta o grassa necessita una emulsi\u00f3 oil-free o gel; una pell seca o sensible, una base nutritiva. Usar un SPF que no t’agradi en textura garanteix que acabar\u00e0s no usant-lo.<\/li>\n
  • Reaplicaci\u00f3:<\/strong> el SPF perd efic\u00e0cia a les 2 hores d’exposici\u00f3. Si treballes a l’exterior o passes temps al cotxe (els vidres no bloquegen el UVA), reaplicar \u00e9s innegociable.<\/li>\n<\/ul>\n

    A NIS+ formulem el nostre fotoprotector facial amb SPF 50+ d’ampli espectre, textura lleugera no oclusiva i actius antioxidants (vitamina E i extracte de te verd) que reforcen la protecci\u00f3 enfront del dany oxidatiu. Sense perfum ni colorants, apte per a pells sensibles.
