How does it work?

Your skin is held together by two proteins. Collagen is the fabric. Elastin is the spring that pulls your skin back after it stretches. Your body made nearly all of its elastin before you were an adult, and it makes almost none after that. A GLP-1 takes off 1 to 2 lbs a week, faster than that spring can adjust: that’s the Recoil Gap. Dr. Kakinagi gives your skin 1,000 mg of marine elastin peptides every day, the building blocks of that spring, while the weight comes off.

How do I take it?

Two capsules a day, with water, any time of day.
Keep taking your collagen, your protein and your workouts. Dr. Kakinagi adds the other half.
Start now, ideally from your next dose. Don’t wait until you see it.
Take it for 12 weeks, the length of the study, and keep going while you lose.

Is it safe with my GLP-1?

Dr. Kakinagi is a protein peptide from fish: no hormones, no stimulants, no collagen filler. It doesn’t change how your GLP-1 works. If you take prescription medication, are pregnant or have a fish allergy, check with your doctor first.

Jennifer R., 46

Started this way too late. At 30 lbs down on Zepbound, I was hiding my arms in cardigans. I added two capsules next to my collagen. 3 months later, I wore a sleeveless dress to my son’s graduation.

★★★★★

Monica T., 39

Everyone told me loose skin only happens after 100 lbs. Mine started at 25. My stomach doesn’t fold the way it did when I sit down, and I’m still losing.

★★★★★

Linda K., 54

Menopause plus Wegovy, and my neck looked older than my face. I didn’t think anything could still work at my age. My daughter noticed before I said a word.

Firm skin starts with the spring underneath.

Made for skin on a GLP-1.

Collagen powders, creams and workouts all work on the fabric of your skin, or on what’s underneath. None of them rebuild the spring. Dr. Kakinagi brings 1,000 mg of Korean marine elastin peptides to your day in two capsules, so your skin gets the building blocks of elastin while you lose, not after.

✓ Made for weight loss on a GLP-1
✓ Two capsules a day

COLLAGEN VS ELASTIN

Collagen is the fabric. Elastin is the spring.

Collagen: keeps your skin thick and strong. It’s the protein everyone sells you, and it’s doing its job. It just can’t pull your skin back.

Elastin: the spring that snaps your skin back after it stretches. Your body barely makes it after adulthood. On a GLP-1, it’s the half that falls behind. Keep your collagen. Add the spring.

Every day. Two capsules. Three simple steps.

1. Take two capsules
Two capsules a day, with water, any time of day.
2. Keep your collagen
Take them next to the collagen, protein and coffee you already have.
3. Start before you see it
From your next dose, for 12 weeks, while the weight comes off.

DESIGNED FOR SKIN ON A GLP-1

Made for skin that’s losing weight faster than it can adjust.

For Ozempic, Wegovy, Zepbound and Mounjaro, pens or pills
Whether you’re 15 lbs or 80 lbs down
For arms, stomach, neck, chest and thighs
For women who already take collagen and still see it
1,000 mg of pure marine elastin peptides, no collagen filler

Nothing worked because nothing rebuilt the spring.

Why they fall short: collagen rebuilds the fabric, not the spring. Firming creams stop at the surface. Radiofrequency and laser cost $1,000 a session and can’t keep up while you’re still losing. A tummy tuck works, but it’s $15,000 to $20,000, a scar from hip to hip and weeks of recovery.

THE STUDY BEHIND IT

Tested in Korea. 12 weeks. Placebo-controlled.

In a randomized, double-blind, placebo-controlled study in Korea, adults aged 35 to 60, mostly women, took marine elastin peptides every day for 12 weeks. They had smoother skin, fewer fine wrinkles and better hydration. The placebo group’s wrinkles got worse. No side effects were reported. Dr. Kakinagi gives your skin 1,000 mg of marine elastin peptides, every day.

It starts long before 100 lbs. Real comments from women on GLP-1s

“I'm down about 35 lbs and definitely starting to show signs of loose skin that I was not prepared for because everyone swears to you that loose skin is only a thing when you lose like 100+ lbs.”
Public comment
“my neck has recently gotten really wrinkly (Ive lost about 30lbs) and I'm only in my early 30s I just didnt expect zepbound to do that to my neck.”
Public comment
“I've lost only 10lbs so far and I can already feel my skin getting increasingly wobbly, specially on my legs.”
Public comment
“I have been taking collagen supplements at the recommended levels every single day for 2 months now in hope that that would help, yet still no change.”
Public comment
“realizing I may need a $20K tummy tuck over 30 lbs of weight loss is kind of messing me up mentally.”
Public comment
“I do feel as though I've traded out one insecurity for something else.”

FAQ

Questions women actually ask

How fast will I see a difference?

Most women feel softer, more hydrated skin in the first weeks, and smoother-looking skin by weeks 4 to 8. Give it the full 12 weeks, the length of the study, and keep going while you lose.

Is it safe with my GLP-1?

It’s a protein peptide from fish: no hormones, no stimulants. It doesn’t change how your GLP-1 works. If you take prescription medication, are pregnant or have a fish allergy, check with your doctor first.

Do I stop taking my collagen?

No. Keep your collagen. It rebuilds the fabric of your skin. Dr. Kakinagi adds the other half, the spring.

I’m already 40 lbs down. Is it too late?

No. Every pound you still lose stretches your skin again. The sooner your skin gets the building blocks of elastin, the better it can keep up with the rest of your weight loss.

Which GLP-1 is it for?

Any of them: Ozempic, Wegovy, Zepbound, Mounjaro, compounded semaglutide or tirzepatide, pens or pills.

How do I take it?

Two capsules a day, with water, any time of day.

How long does one bottle last?

30 days. 60 capsules, two a day. The 3-bottle protocol covers 12 weeks.

Can I take it with my other supplements?

Yes. Take it next to your collagen, protein, multivitamin or electrolytes. If you take prescription medication, check with your doctor first.

Do you ship to my country?

We ship to the US. Delivery takes 7 to 12 days, with tracking.

What if it doesn't work for me?

Take it for 90 days. If your skin isn’t keeping up better, email us and we refund every penny.
