Board-Certified Dermatologist: 'There Are Two Types of Crepey Arms. I Spent 19 Years Treating Both the Same Way. I Was Wrong.'

April 7, 2026 at 10:30 am EST

There are two types of crepey arms. One type responds to retinol, microneedling, and everything your dermatologist prescribes. The other type — the one that happened fast, in a few months — doesn't respond to any of it. And there's a biological reason nobody in American dermatology is talking about.

I know because I spent 19 years treating both types with the same protocol. And I only found out there were two types when my own arms stopped responding to everything I prescribed.

My name is Dr. Rebecca Hayes. Board-certified dermatologist. Published in the Journal of Dermatologic Surgery. Over 2,400 patients. And until September of last year, I had no idea I was failing half of them.

Here's What I Mean By Two Types

Type 1 is gradual. A woman loses roughly 1% of her collagen per year after menopause. Over a decade, the skin on her arms gets thinner, slightly looser, slightly less elastic. She notices it slowly. Retinol helps. Peptides help. Professional treatments help. Not perfectly, but measurably. This is the type every American dermatologist is trained to treat. This is what's in our textbooks.

Type 2 is different. A woman's arms are fine — normal, unremarkable, hers — and then sometime between perimenopause and two years post-menopause, they change. Not over years. Over months. Sometimes what feels like weeks. She looks down one morning folding laundry or catches her arm in a photo or steps out of the shower and the skin on her upper arms looks like it belongs to someone twenty years older. It wasn't there in March. By August, it's all she can see.

Type 2 doesn't respond to retinol. It doesn't respond to microneedling. It doesn't respond to peptides, professional peels, or prescription tretinoin. Not because those are bad treatments. Because they were designed for Type 1. And Type 2 is a fundamentally different biological event.

I didn't learn this distinction in medical school. I didn't learn it in residency. I didn't learn it in 19 years of continuing education.

I learned it in September 2023. In Paris. From a 72-year-old French esthetician named Anne Beaumont. In about thirty minutes.

But First — Something I've Never Said Publicly

At 58, I am Type 2.

My arms changed between March and June of 2022. I was folding laundry in my bedroom. I looked down at my forearm in the afternoon light and the skin had a texture I didn't recognize. Crepey. Dimpled. Loose in a way it hadn't been the month before. I pressed my thumb into my upper arm. The indent stayed for four seconds before slowly creeping back.

I'm a dermatologist. So I did what I tell my patients to do. Prescription tretinoin — $78 every eight weeks for a year. Three rounds of professional microneedling — $720 total. Medical-grade peptide serum — $145 a bottle, five bottles over ten months.

Fifteen months of treatment. My arms looked the same. Possibly worse.

And here's what haunted me: I had other patients on the exact same protocols whose arms were improving. Women who'd come to me with crepey skin on their upper arms, and after six to twelve months of retinol and procedures, they showed measurable results.

Why was it working for them and not for me?

I didn't have an answer. I assumed my skin was somehow resistant. Unlucky genetics. I stopped looking at my arms in the mirror and started wearing cardigans year-round.

September 2023. Paris. The Moment Everything Changed.

The International Dermatology Symposium in Paris. 78 degrees. I was the only woman at the coffee break in long sleeves.

That's when I saw Anne Beaumont. 72 years old. Sleeveless dress. Arms that looked like they belonged to a woman of 50. Smooth. Elastic. Not a trace of crepey texture.

I introduced myself. I couldn't help asking.

She didn't give me a product recommendation. She asked me a question.

"The patients whose arms improve on your standard protocols — did their skin change gradually over years? Or suddenly over months?"

I opened my mouth to answer and realized I'd never thought to separate them.

She nodded.

"That's because American dermatology doesn't separate them. You have one diagnosis: age-related skin laxity. One category. One set of protocols. But there are two completely different biological events happening, and only one of them responds to what you're prescribing."

She gestured to an empty table.

"Sit down. I'm going to explain why half your patients improve and the other half don't. And why your own arms haven't responded. It has nothing to do with genetics."

Type 1: Gradual Decline

Anne explained that in Type 1, a woman's collagen production slowly decreases — about 1% per year after menopause. The skin thins over a decade. The structural cushion layer between her blood vessels and the skin surface gets gradually thinner. Surface treatments — retinol, peptides, microneedling — can stimulate collagen production at the epidermal level enough to slow this process and modestly reverse it. For Type 1, the American protocols work. Slowly, imperfectly, but they work.

Type 2: Sudden Hormonal Collapse

Anne drew a sharp line dropping off a cliff.

"In Type 2, the hormonal shift triggers something your textbooks don't cover. The fibroblasts — the cells deep in the dermis that produce collagen and maintain the structural cushion — don't gradually slow down. They go dormant. Like a switch turning off. Two to three years' worth of cushion collapse happens in three to six months. The structural layer between her blood vessels and the skin surface doesn't thin slowly. It drops out."

She tapped the napkin.

"This is why your arms changed in months, not years. And this is why nothing you prescribed worked — tretinoin stimulates surface-level collagen. Microneedling triggers wound-response healing in the epidermis. Peptides signal the surface. But the collapse happened in the dermis. Four to five millimeters below where any of your treatments reach. You've been treating the ceiling when the foundation fell."

Why American Dermatology Doesn't Teach This

I asked her how many dermatologists she'd explained this to.

"Many. At European conferences. We've been publishing on sudden hormonal fibroblast dormancy in French and German journals since 2015. American dermatology conferences are sponsored by pharmaceutical companies that make surface treatments. They don't present research that makes their products irrelevant for half the patient population."

The Three-Part Protocol That Reverses Type 2

I asked her what reverses Type 2.

She drew three overlapping circles.

"Three things. Simultaneously. At the dermal layer. Miss one, and the other two don't matter."

First: Penetrate to the collapse.

Anne explained that my prescription cream was 85% water. Water-based formulations have a molecular weight too high to pass through the epidermis to the dermis. They sit on the surface. The collapse lives four to five millimeters below. Only pure plant oils with a molecular weight under 400 Daltons — specifically Passionfruit seed oil and Rice Bran oil — are light enough to pass through the epidermal barrier and actually reach the dormant fibroblasts.

"You've been mailing letters to the right person at the wrong address for nineteen years," she said. "The ingredients might be correct. But they never arrive."

Second: Reactivate the dormant fibroblasts.

The fibroblasts didn't die. They went into hormonal shock. They're dormant — asleep, not dead. But peptides and retinoids don't carry the biochemical signals that dormant fibroblasts recognize. You need specific botanical compounds — Anne has used Wakame seaweed extract and White Lupin for decades — that send reactivation signals to cells in hormonal shutdown. European research documented a 340% increase in fibroblast activity in hormonally-collapsed tissue using these compounds.

"Your cells are waiting to be woken up," Anne said. "You just haven't been speaking their language."

Third: Protect the new structure as it forms.

Anne explained something that made my stomach drop. "Even if you penetrate to the right depth and reactivate the dormant cells and they start rebuilding collagen — in hormonally-collapsed tissue, that new collagen is extremely fragile. Without antioxidant protection at the dermal level, it breaks down within hours of being produced. You rebuild and lose it in the same day."

Vitamin E, Acai, and Babassu oil. Dermal-layer antioxidants that shield fragile new collagen as it forms.

Penetrate. Reactivate. Protect. All three. Simultaneously. At the dermal layer.

"That's what reverses Type 2," Anne said. "Surface treatments cannot. Not because they're bad science. Because they're aimed at a layer where the problem doesn't exist."

I Tested It On Myself First

I started the three-part protocol on myself that week.

The oil absorbed in thirty seconds. Not sitting on the surface like the creams I'd been using for fifteen months. Going somewhere. I could feel the difference immediately — not a result yet, just a delivery system that was clearly reaching a depth my prescriptions never had.

Day 7. Elasticity pinch test: 3.4 seconds. Down from over 4. First measurable change in fifteen months.

Day 12. Folding laundry. Same bedroom. Same afternoon light. I looked down at my forearm and the crepey texture looked less deep. Like something was rebuilding underneath the skin rather than sitting on top of it.

Week 3. Skin fold measurement: 11mm. Down from 14mm.

Week 5. I reached for a mug on the top shelf at work without thinking. My sleeve pulled up. A colleague glanced at my arm. No reaction. Not the careful non-reaction people give when they notice something and look away. Actual non-reaction. There was nothing to notice.

I went to the bathroom and looked at my upper arm in the fluorescent light. For fifteen months, fluorescent light had been the enemy — it showed every crease, every fold, every sign of collapse. That afternoon, I just saw an arm.

Week 10. Full clinical assessment. Elasticity: 2.2 seconds. Dermal thickness: 1.1mm, up from 0.7mm. The collapsed cushion layer was rebuilding. The dormant fibroblasts had reactivated.

Type 2. Fifteen months of failed American protocols. Reversed in ten weeks — because someone finally treated the right layer.

Then I Called My Patients

Not all 37. I started with the ones I thought about most. The ones I knew were Type 2. The ones I'd kept on surface protocols for months knowing — in retrospect — that it wasn't working.

Diane, 55. Fitness instructor. The one who told me at her first appointment: "I'm a fitness instructor who used to have amazingly toned arms. Menopause changed all of that. And nobody can explain why exercise doesn't fix it."

Now I could explain it. Exercise builds muscle. Muscle sits below the dermis. The crepey texture is a collapsed cushion layer ABOVE the muscle and BELOW the skin surface. Diane's muscles were perfect. Her cushion layer had collapsed. No amount of tricep curls or push-ups or weights reaches the cushion layer. That's not what exercise does. But Type 2 women like Diane are the most frustrated — because they did everything right and still failed.

The Only Product That Meets All Three Requirements

The only product I've found that meets all three of Anne's requirements is Lumié Queen Oil.

I sent their documentation to an independent lab. Results confirmed:

Twelve body oils tested. This was the only one that delivered all three elements to the depth where sudden hormonal collapse actually happens. The same protocol Anne has used in Paris for over a decade.

$59 a bottle. Two-week supply. The 60-day protocol — four bottles, $236 total — costs less than a single round of microneedling that can't reach the dermis.

How To Know Which Type You Are

It's one question. The same question Anne asked me. The same question nobody in American dermatology is trained to ask:

Did your arms change gradually, over years? Or suddenly, over months?

If it was gradual — over five, ten, fifteen years — you may be Type 1. Standard treatments may help. Talk to your dermatologist.

If it happened fast — if you can point to a season, a summer, a few months where your arms went from normal to crepey — you are likely Type 2. And the treatments designed for Type 1 are not designed for you. They target the surface. Your collapse is deeper.

P.S. — Susan called me last week. She said something that keeps replaying in my head. "I spent eighteen months thinking my skin was broken. Turns out the treatments were broken. I just wasn't the right type for them." She was right. And nobody had ever told her there were types.

P.P.S. — Margaret, at month eighteen, told me: "If someone had explained this to me at month four when I first walked into your office, I'd have spent $59 instead of $3,200 and gotten my arms back a year earlier." I didn't have anything to say to that. She was right too.
