Silicones in skincare – the facts

Is there an ingredient in skincare that receives more hate than silicones? Probably. SLS, just to name one. Or fragrance, like I recently discovered (here).

But for the sake of style, let´s just asssume that the answer is: No!

And then focus on the fact whether or not the hate that seems to run so deep in the beauty community is actually scientifically backed up.

I mean, you are probably already guessing it by reading this introduction, but let´s approach the discussion with an open mind and see what I have found.

The Ordinary Matrixyl 10% + HA

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.

Emollients vs. Occlusives – Everything you need to know

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.

And as this is the third in a series of blog posts, I highly suggest you catch up with „Do you really need a moisturizer? The difference between dry and dehydrated skin“ and „Humectants – Everything you need to know“ first. Not that there are any spoilers in here, but it will make it easier to understand.
