But can we believe with our eyes closed these tempting promises of smooth, firm and radiant skin thanks to collagen supplements? A research unit at Anglia Ruskin University looked into the question. And answers it after analyzing all the rational data available on the subject, i.e. 16 scientific journals and 113 clinical trials carried out in several countries. His conclusions published in the Aesthetic Surgery Journal Open Forum shed more light on the real benefits of collagen intake and reveal a more nuanced reality.

Positive effects, yes but…
Their work shows that collagen can have a positive effect on certain skin characteristics, such as hydration and elasticity, but these results remain modest and vary depending on the participants and the formulations used.
Concerning the drastic reduction or even disappearance of wrinkles created by boosting the skin with collagen, often put forward by brands, it is not supported by researchers. Who argue a lack of available data on the real reduction of wrinkles.
Evidence shows that taking collagen has positive (but very variable) effects on the texture and hydration of the skin, according to researchers. But daily sun protection, a balanced diet rich in vitamin C, sufficient sleep and appropriate care remain determining elements for preserving the skin, they emphasize.
One thing, however, is decisive in the appearance of the benefits of these cures. It is the regularity of the daily intake in addition to a long-term intake.

The joints also benefit
Furthermore, research notes that several valid clinical trials show possible benefits for tendon and cartilage health. This leads to a reduction in joint pain and stiffness, particularly in people suffering from osteoarthritis.
