CONSUMER TEST CONFIRMS THE EFFECT
Collagen Intensive impresses in a user study
40 participants report positive changes within 8 weeks!
Consumer test with 40 participants
In cooperation with Kalia Lab and under the medical supervision of Dr. med. Constantin Weil von der Ahe, we conducted an 8-week user observation with 40 women.
During this period, every participant took 2.5 g of Collagen Intensive daily – their experiences were systematically recorded and compared with data from before and after use.
Method
During the observation phase, the participants' skin was analysed with a state-of-the-art 3D skin scanner.
We measured skin texture, pore size, wrinkles and pigmentation changes, alongside structured questionnaires in which the participants rated their complexion, hair, nails, mobility and general well-being. The result is a comprehensive picture of objective measurements and personal experience.
Note: this was an internal user observation, not a clinical study. The results cannot be generalised and serve solely to accompany the product.
The results speak for themselves
