    Foire aux questions

    Como Miles explica no podcast, os umectantes são substâncias higroscópicas que funcionam como pequenos ímãs de umidade. Em vez de apenas molhar a superfície, eles possuem a capacidade técnica de puxar a água do ambiente ou das camadas mais profundas para a superfície. Isso evita que a água evapore rapidamente, melhorando a textura e garantindo que a hidratação permaneça onde é necessária.

    O PCA Sódico, também conhecido como Pidolato de Sódio, é uma substância naturalmente produzida pelo corpo humano. Lena e Miles destacam que ele faz parte do Fator de Hidratação Natural, ou NMF. Por ser um componente biológico, ele é extremamente seguro e eficaz, atuando como uma estrela silenciosa na manutenção da flexibilidade da pele e na retenção de umidade na queratina.

    Embora a Glicerina seja frequentemente considerada o padrão ouro da hidratação, Miles aponta que testes de laboratório mostram resultados superiores para o PCA Sódico. Ele se mostrou significativamente mais eficiente que a Glicerina para reter umidade na queratina, a principal proteína da pele e do cabelo. Essa maior potência torna o PCA Sódico um aliado fundamental para quem busca uma hidratação profunda e duradoura.

    NMF é a sigla para Fator de Hidratação Natural. Trata-se de um conjunto de substâncias, incluindo o PCA Sódico, que a nossa própria pele produz para se manter hidratada e saudável. No diálogo, Miles reforça que entender o NMF é essencial para compreender por que certos ingredientes são mais compatíveis e eficazes na manutenção da barreira cutânea e da flexibilidade natural do corpo.
