Have you ever felt that way when someone tried to sell you a skincare product? I know I have. Peptides have been around for a few years, they are the “thing to have” in your routine, yet there is a lot of insecurity about what they actually do.
Or if they even do anything.
And that is okay, because the jury is still out on that. And the fact that there are over 100 peptides doing different things doesn´t really help either.
So I put on my glasses and filmed a video for you on that topic.

Sometimes a tiny letter can make a huge difference. Make you question things, for example. In cosmetic science, that letter is usually a „v“.
Why a „v“ you ask?
And imagine how great it would have been had I said a „y“ -Y a „y“?
Because „in vivo“ sounds pretty similar to „in vitro“, but in terms of results there is a huge difference.
See, many ingredients proove their claim on human cells. In the lab, in petri dishes, swimming in a special broth. Which is NOT the same as being attached to a moving human being, always on the run and with many other cofactors like sweat, spf and (other) sexy things (for the sake of the alliteration) that could impede penetration.
Because skin is actually designed to stop things from penetrating (as we have learned here), and we can´t switch that off on demand.
But why am I going on about the difference the „v“ makes? Because when it comes to peptides, there are two different camps. The „It works“ one and the one that will tell you that peptides are too big to penetrate the skin „in vivo“ and thus are a waste of money.
And if you haven´t made up your mind yet, The Ordinary Matrixyl 10% + HA will let you see for yourself without breaking the bank.
I once heard about someone that always read the last chapter of a book first. Reason behind that? She wanted to make sure she’d know the end, even if something happened to her before she could finish reading.
I don´t do that. I read my books from start to finish, maybe skimming over some parts here and there, but following the story as it was written.
About a month ago, I uploaded a video about the difference between dry and dehydrated skin (here if you missed it).
I promised to do one more about humectants, emollients and occlusives as a follow up and here I am to live up to that promise.
Not exactly though, as I had so much to say about humectants that it filled a video all by itself. The one (ones?) about emollients and occlusives will follow at a later date.
Which will make it easier just to get the information you need, and if by last months video you already know you don´t care about humectants, you can totally skip this upload and invest your time in something more productive.
That would be of course your loss, so I suggest you grab something to drink (we are talking about hydration after all) and follow along.
