Proteins in skincare

Hello All,

What is your opinion on proteins in skincare? Is there scientific proof that they have any benefits for skin and if so which ones (milk, oats, silk)?

I avoid proteins as they can have a negative impact on viscosity, rather expensive and I am not persuaded that they do anything.

Thank you in advance!

    Not surprisingly, I think they are mostly claims ingredients.

    Proteins work as moisturizing ingredients (humectants) and film formers which might be able to protect from surfactant irritation.

    The protein source differs in distribution of amino acids but I highly doubt you could show much effective differences. Just a marketing story difference.

  • Thank you Perry. This is what I thought.

    I totally agree with Perry.
    Plus they're hard to preserve.
  • I have some collagen protein (powder). I was not very impressed and haven't tried to explore other proteins but everyone talks about proteins now. Thank you for your comments.

    There is a big difference between structural proteins like collagen and elastin, which can do little for your skin because you need to make your own, and active proteins like superoxide dismutase, which, if active, can help with redox stress caused by pollution and endogenous reactive oxygen species.
  • Has anyone tried Quinoa Hydrolysed Protein?

    Has anyone tried Quinoa Hydrolysed Protein?
    Certainly. It is used quite a bit when the client is seeking to be "gluten free." Like other proteins, the results were unremarkable.

    I doubt you could find any significant difference between Quinoa hydrolyzed protein and other hydrolyzed proteins. Maybe the amino acid distribution might be a bit varied but nothing that would make a substantial difference.
  • Thanks guys, so I could use it at least in Vegan preparations.
