Lost Weight on a GLP-1? Here Are 8 Reasons Women Are Switching From Collagen to Elastin for Loose Skin
Updated November 2026
Ozempic, Wegovy, Mounjaro and Zepbound are helping millions of women finally lose the weight. Then comes the part nobody warned them about: loose, hanging skin on the belly, arms, chest and face.
Here's why it happens. Your skin was stretched around that weight for years. To pull back, it needs elastin, the protein that lets skin snap back like a rubber band. But your body stopped making new elastin in your mid-twenties. Lose 70 or 80 pounds fast and the skin has nothing left to recoil with.
That's why so many women are trading their collagen powder for a marine elastin supplement. Here's what they're noticing.
1. It Targets the Loose Belly "Apron"
Your belly carried the most weight for the longest, so it's where loose skin hits hardest: the apron that folds over your waistband when you sit, and the crepey, rippled skin you hide under loose tops.
Claranova Labs Elastin Peptide gives that skin the elastin it ran out of, so it can start pulling back in. Most women say the skin feels thicker and springier by the second month.
2. It Targets Loose "Bat Wing" Arms
The backs of the arms are one of the first places loose skin shows after weight loss. It's the reason so many women stay in long sleeves all summer and dread waving at the camera.
The same 1,000mg of marine elastin peptides a day works on your arms too, because elastin is in your skin everywhere. Less swing when you wave, and short sleeves without thinking twice.
3. It Helps With Saggy Breasts and a Crepey Neckline
Breasts are mostly fat, so they lose volume fast on a GLP-1. The skin around them was stretched for years, so everything sits lower, and the neckline turns thin and crepey.
Elastin is in the skin across your whole chest. Giving it the protein it ran out of helps the skin firm up and hold its shape, so fitted tops and swimsuits fit right again.
4. It Helps Fight "Ozempic Face" and a Sagging Jawline
Your face loses fat too. That leaves sagging jowls, a loose neck, hollow cheeks and hooded eyes, the look friends describe as "tired."
Firmer, springier skin around the face and neck is one of the changes women mention most, often before they notice it anywhere else.
5. It's the Protein Collagen Was Never Going to Replace
Collagen gives skin firmness and structure, like a frame. Elastin is what pulls skin back after it stretches, like a brand-new rubber band.
Loose skin after weight loss is a snap-back problem. That's why a year of collagen powder didn't change it. More frame doesn't fix worn-out rubber bands.
6. 1,000mg a Day, Backed by a Clinical Study
In a 12-week clinical study on marine elastin peptides, elastin went up 250% and collagen went up 100%.
Claranova Labs Elastin Peptide delivers 1,000mg of marine elastin peptides from wild-caught fish in two capsules a day. It's made in the USA in a GMP-certified facility and third-party lab tested. Keep taking your GLP-1, and add two capsules with your morning coffee.
7. It Costs a Fraction of a Tummy Tuck or Arm Lift
Surgery cuts away the extra skin. It doesn't fix why the skin went slack. Elastin works from the inside, on every area at once.

4.8 ★★★★★ from 3,000+ reviews
Mounjaro skin is tightening
Lost 70 lbs on Mounjaro. The loose skin was devastating. Nothing worked. Three months on this and my stomach is visibly different. Not perfect but noticeably better. Reordering.
My daughter was right
My daughter bought this for me after I complained about the loose skin on my neck from Ozempic. It's working. My neck actually looks better. I don't angle my phone on video calls anymore.
Finally wore a tank top
The loose skin on my arms after losing 140 lbs kept me in long sleeves for 3 years. I'm wearing short sleeves again. That's worth every penny.
Saving my $12,000
Lost 90 lbs. Loose skin everywhere. Was about to book surgery. Decided to try this first. Glad I did. Stomach is tighter. Saving my $12,000.
Wish I found this sooner
Wasted almost a year on collagen for my loose skin. This actually works. Stomach is firmer and the skin on my arms doesn't swing like it used to.
