From New York to Berlin, wellness influencers and beauty bloggers have helped turn this supplement into a global phenomenon.
It’s praised as a miracle fix for aging skin, promising fewer wrinkles, improved elasticity, and that youthful glow so many crave.
With sleek packaging and glowing testimonials, it’s no wonder the product has gained a loyal following.
It’s mixed into lattes, smoothies, and even morning oats. But not everyone is convinced by the hype.
Researchers are skeptical
While marketing campaigns boast about transformative results of collagen, researchers are urging consumers to dig deeper.
Two scientists from Denmark — dermatologist Dr. Cecilie Johansen and pharmaceutical professor Anton Pottegård — have examined the science behind the trend.
The studies are too short, too small, and not convincing. Most trials run for just 8 to 12 weeks — far from enough to determine any long-term benefit for skin health.
According to Dr. Cecilie Johansen, the supposed improvements may simply be due to increased skin moisture.
Moisturized skin can feel smoother and look more elastic — but that doesn’t mean wrinkles are truly reduced.
“I would never buy it myself”
Dr. Cecilie Johansen makes her stance clear. She believes the marketing is misleading, and the promised anti-aging results don’t hold up under scientific scrutiny.
The reality, she says, is far less glamorous than the Instagram-friendly narratives suggest.
“So it’s misleading, and I would never buy it myself”, she told Danish media Berlingske.
Her warning is a reminder to think critically — especially in an industry where science often takes a back seat to sales.
As tempting as the promises may be, the evidence simply isn’t strong enough to support the claims, according to Dr. Cecilie Johansen.
