In recent years, you may have seen fitness influencers or top models praising collagen drinks, claiming that a sip each morning plumps and perfects skin.
We’re here to investigate the truth behind the fad, so you can decide whether you should factor collagen drinks into your daily routine and beauty budget.
What are collagen drinks?Collagen is the crucial protein which keeps our skin firm. Miserably, after the age of 20, we produce about 1% less collagen in our skin year on year, which thins the skin and contributes to wrinkles.3
Collagen drinks claim to combat collagen loss by wiring this potent protein, in the form of peptides, straight to the stomach. The idea is that it’ll give you a glow which begins on the inside.The best bit? Modern science suspects it works! After ingesting a collagen drink, the absorbed collagen peptides make their way into the skin, where they remain for around 14 days.4
Benefits of collagen drinksIngesting collagen has been linked to positive benefits for skin and nails, including:
- Reduced wrinkles. Women who ingested collagen for 12 weeks had less visible wrinkle depth than a comparable group of women who had not.5
- Skin suppleness. A study found that a group of women who took collagen supplements for eight weeks enjoyed improved skin moisture quality and youthfulness, in comparison with a group who didn’t.6
- Improved collagen production. One scientific study proposed links between ingesting collagen and increased collagen production within the body.7
- Better nail growth. Researchers found that a group who took collagen supplements every day developed stronger, longer nails, more resistant to damage.8
- Increases other proteins which benefit the skin. Elastin and fibrillin are also essential for skin firmness and contribute to the youthful look of healthy skin. Ingesting collagen has been connected to increased elastin and fibrillin production, too.9
Be advised that many of these gleaming scientific studies, which sing the praises of collagen drinks, were sponsored by collagen drink manufacturers.
