CLINICAL TEA: Wellness science, spilled. with Katherine MacBarron, PA-C 🫖

Unpopular opinion incoming — and I say this as someone who has been working in women’s hormones since 2013.

There are forms of testosterone I almost never recommend for women. And the reasons why might change how you think about hormone therapy entirely.

Watch before you start anything new.

Retinol. Retinal. Tretinoin. Adapalene. Retinol esters.

They’re all in the same family — but they are not the same thing. The reason most people’s skin freaks out on retinoids isn’t the retinoid itself. It’s where they started on the ladder.

Some of these need to go through multiple conversions before your skin can even use them. That’s not a flaw — for a lot of skin types, that’s actually the whole point.

I’m breaking down every rung in this video. Worth a save if retinoids have ever confused or frustrated you.

GLP meds are amazing — but they don’t get to choose what weight you lose. Fat? Yes. Muscle? Also yes. And that’s a problem.

There are three things you can do right now to protect your muscle while you’re on your GLP journey, and I break all of them down in this video.

If you’re on a GLP medication and want to make sure you’re getting the most out of your journey, drop a comment, send me a message or come see me at Masters Medspa in Irvine, CA.

Individual results may vary. Consult with a licensed medical provider before starting any medication.

Lines get all the attention — but texture is actually what’s aging your skin faster. 👀

The wrinkly shirt analogy in this one? Chef’s kiss.

We use UltraClear here at Masters and I honestly love what it does for skin quality. Watch to the end. 🖤
