Estava lendo essa manhã um estudo publicado com o título "The influence of surfactants and hydrolyzed proteins on keratinocytes viability and elasticity" e gostaria de dividir com vocês.
Todos sabemos que surfactantes prejudicam nossa pele, mas este estudo em particular é interessante porque mostra a alteração nos filamentos de actina dos queratinócitos. Pra quem não sabe, entre todos os filamentos que compõe o citoesqueleto dos queratinócitos, os filamentos de actina são os principais responsáveis pela manutenção da resistência e da resiliência da célula. Por isso se usarmos muito produtos de limpeza com tensoativos agressivos, como o lauril sulfato de sódio, teremos células mais fracas em nossa epiderme. Além disso, o estudo cita os benefícios de um colágeno hidrolisado de baixo peso molecular. Neste caso temos no mercado ativos como o Rellagen ou mesmo o Oligo HA, ambos com baixo peso molecular e que podem ser uma alternativa para minimizar os danos causados pelos surfactantes.
Surfactantes mais suaves
Lembre-se sempre que também podemos substituir os surfactantes mais agressivos por outros mais suaves. Segue uma lista pra ajudar vocês:

It was really eye-opening to read about how surfactants actually interact with our skin barrier since we use these products every single day without thinking. I remember being so deep into my technical studies last year that I barely had time to even look at the labels on my soap or shampoo. I actually decided to get some Guaranteed pass PRINCE2 exam help at that time because I was completely overwhelmed trying to balance my science coursework with professional certifications. It is so important to understand the chemistry of what we put on our bodies, but sometimes you just need to find a way to manage all the different things on your plate.
