Looking good at 45: what actually works (and what is just very good marketing)

AI Tools for Every Chapter of Her Life

ISSUE 18  ❖  LOOKING GOOD AT 45: WHAT ACTUALLY WORKS (AND WHAT IS JUST VERY GOOD MARKETING)

I have a PhD in chemistry and worked in the pharmaceuticals industry for almost 20 years. I’m not an expert in dermatology, but I can read a skincare label. And I will tell you with complete confidence that the skincare industry relies heavily on the fact that most people cannot.

‘Clinically proven.’ Proven to do what, exactly, in what study, conducted by whom? ‘Visibly reduces fine lines.’ Visibly, meaning measurably, or visibly meaning your best friend was being kind? ‘Dermatologist-tested.’ Tested for what? One dermatologist looked at it and didn’t immediately recoil? These phrases don’t really mean anything. They're designed to make you feel confident without actually proving anything.

I’m not saying nothing works. Plenty works. But figuring out what actually works for your skin, at your age, with your specific concerns, in a routine you will actually follow — that requires cutting through a significant amount of noise. I’ve been doing a lot of this research for myself lately, because I’m 46 and I am paying more attention to my skin than I was ten years ago. The lines are real. The dullness is real. And the procedures I’ve been thinking about are something I want to approach with actual information rather than an Instagram ad.

So I did what I do: I researched it. I used AI to help me cut through the noise. This is what I learned. I’m sharing it as a fellow “researcher,” not an expert. And the prompts in this issue are designed to help you do the same investigation for your own skin.

THE SKINCARE FOUNDATION

What the Research Keeps Pointing To

I’m not a dermatologist, and I want to be clear about that upfront. But from everything I’ve read and researched, a few categories keep coming up consistently as having the most clinical evidence behind them for aging skin: sunscreen (SPF, daily — this one is not debated), retinoids (probably the most studied anti-aging ingredient category that exists), vitamin C (antioxidant protection and brightening), and a good moisturizer focused on barrier support.

My understanding is that most of what’s beyond those four falls into ‘supporting cast’ or ‘very good marketing’ territory, but I’d encourage you to ask AI and your dermatologist directly, because this is an area where individual skin really does vary. The prompt below is a good starting point for that conversation with AI:

THE RETINOL CONVERSATION

The One Thing That Kept Coming Up in My Research

Every time I went down a skincare research rabbit hole, retinoids kept coming up. There are decades of studies on collagen production, cell turnover, and hyperpigmentation. My understanding is that this is one of the more well-researched categories in skincare, which is why it gets recommended so consistently.

That said, they’re also the thing most women either avoid because they’ve heard it’s harsh, or use incorrectly and give up on. I asked AI to help me understand how to actually use them correctly, and the answer was more nuanced than I expected:

THE K-BEAUTY ANGLE

What I’ve Found Genuinely Interesting About Korean Skincare

I've been drawn to Korean skincare for a few reasons: I'm Asian, so it felt like a natural place to start, I kept seeing it everywhere on social media, and honestly, when I tried some of it, my skin responded. Double cleansing, in particular, has made a real difference for me lately.

I'm not an expert here, to be clear. This is personal experience plus some research, not a dermatology credential. But I was curious enough to look into why it seemed to be working, and I asked AI to help me understand the layering method and the ingredients that kept showing up.

COSMETIC PROCEDURES

How to Research Before You Book

I’ve been thinking about cosmetic procedures. Specifically: what’s actually worth it, what I’m not ready for, and how to tell the difference between a good result and a result that makes you look like a different person. The internet is genuinely not helpful here. Everyone is either very pro or very anti, and very few people are honest about their before.

I’m not in a position to tell you what procedure is right for you. That’s a conversation for a qualified provider. But I’ve found AI useful for getting educated before those appointments, so I’m walking in with real questions rather than just hoping someone tells me what to do:

THE INSIDE-OUT PIECE

What I Keep Reading About Skin Health From the Inside

This is an area where I feel more comfortable given my background though I’d still encourage you to talk to your doctor before making changes. From what I’ve come across in my research, things like adequate protein, hydration, omega-3 fatty acids, and a handful of supplements seem to come up consistently in the context of skin health. But the supplement space, in particular, is full of noise, and I wanted AI to help me sort the evidence from the marketing:

YOUR ASSIGNMENT THIS WEEK

Run your current routine through the ingredient decoder.

Take the last three products you bought. Paste each ingredient list into AI and ask what you're actually getting. You might find out that something you paid a lot for isn't doing much — that's a useful (if slightly annoying) thing to know.

Then go back to the very first prompt in this issue — the one that builds your full routine — and see how what you're currently doing compares to what it suggests. Use all of this as a starting point for a conversation with your dermatologist, not a replacement for one.

Until next week,
