And when you have a damaged skin barrier, that stratum corneum has cracks in it and environmental allergens or irritants are able to get in and water is able to get out.
We call that transepidermal water loss or TOOL.
Like it's evaporating out?
Yes, it's evaporating out.
So we are constantly in this state of trying to get water into our skin and water is constantly trying to get out of our skin.
And if you have a damaged skin barrier, that's happening at a more rapid rate and that can lead to inflammation in the skin, which can lead to redness, premature skin aging, etc.
I think the easiest way to know if your skin barrier is damaged is when you feel any type of stinging, burning, or discomfort when you apply a regular kind of bland moisturizer.
If you're using a product that doesn't have actives in it, like vitamin C or acids, and you're still having stinging when you apply it, that is a really good indicator that your barrier is not fully intact.
Okay, so what do we do if our barrier is not intact?
The first thing I have people do is look at their skincare regimen and take out anything that isn't an essential, which is essentially you're going to do cleanser, moisturizer, sunscreen, everything else you just put on pause.
And you're basically going to use those really consistently until your skin feels better again.
And you can do things to support your skin barrier, like using a really occlusive ointment like Aquaphor or even Vaseline.
A lot of people are nervous to use those types of thicker ointments on their skin, but they can be incredibly helpful with
repairing your skin barrier.
That's why we have people use it after a CO2 laser, for example, because it really prevents that trans-epidermal water loss, and it kind of is a comfort to your skin.
Yeah, it's independent.
There's a huge misconception that Vaseline and Aquaphor aren't moisturizers.
They are.
They are not the most optimal moisturizer, so you could use cream-style moisturizer on your skin.
None of the moisturizers really work by providing more moisture.
