The Liz Moody Podcast · The Root Causes Of Hair Loss, Acne & Aging—What's Actually Worth Your Money + What's Total BS · 22 Apr 2026 podcast

First of all, retinol, not good for acne.

It just doesn't work enough and as potently as we need it to.

So you should either be using prescription tretinoin or adapalene gel, which used to be prescription, but is also retinoic acid.

It's the active molecule.

It's just a third generation retinoid instead of tretinoin, which is a first generation retinoid.

But they're essentially working on the same receptors and as directly as either one.

And then retinol, is that good for aging?

Yes.

So retinol can be good for aging.

So it's not quite potent enough to have consistent effects on acne, but can help with fine lines, collagen production.

But if someone was tolerating retinol really well, there's more data to support that using tretinoin regularly will offer more benefits in the skin.

Yeah, so one, not everyone has access to prescriptions, but more so I would say there are a subset of people who just can't tolerate tretinoin.

Like no matter how they layer it or how slowly they try to introduce it, it will just always cause irritation in their skin.

And those are the cases where I would say investing in a good retinol that's sort of tailored for sensitive skin can be valuable, but that's kind of the only exception.

Yes.

When you're looking at photo aging, so fine lines, wrinkles, hyperpigmentation, 0.025 tretinoin has been shown to be as effective as 0.1% tretinoin.

When it comes to acne, the stronger or higher strengths can be better if you can tolerate them, but there's no reason you should be suffering with 0.05 tretinoin when you could be using 0.025.

Oh, I have so many people who come in and in their consultation, I can see their skin is like visibly peeling off.

And I'm like, let me guess, you're using Tretinoin.

They're like, yes, how can you tell?
