But can we believe the enticing promises of smooth, firm, and glowing skin thanks to collagen supplements with closed eyes? A research team at Anglia Ruskin University has delved into the matter and provided answers after analyzing all available rational data on the subject, including 16 scientific reviews and 113 clinical trials conducted in multiple countries. Their findings, published in the Aesthetic Surgery Journal Open Forum, shed a more precise light on the real benefits of collagen ingestion and reveal a more nuanced reality.

Positive effects, yes but…
Their work shows that collagen can have a positive effect on some skin characteristics, such as hydration and elasticity, but these results remain modest and vary depending on the participants and formulations used.
Regarding the drastic attenuation or disappearance of established wrinkles by boosting the skin with collagen, often emphasized by brands, it is not endorsed by the researchers. They argue a lack of available data on the actual reduction of wrinkles.
On the other hand, collagen intake has positive effects (but very variable) on skin texture and hydration, according to the researchers. However, they emphasize that daily sun protection, a balanced diet rich in vitamin C, adequate sleep, and appropriate skincare are crucial elements for skin preservation.
One crucial aspect in experiencing the benefits of these treatments is the regularity of daily intake over an extended period.

Joints also benefit
Furthermore, the research notes that several valid clinical trials show potential benefits for tendon and cartilage health. This translates to a reduction in joint pain and stiffness, especially in individuals with arthritis.
