FIRMS UP THE SKIN
Improves skin elasticity by up to 30% after just 4 weeks*
REDUCES WRINKLES
Reduces wrinkle volume by up to 50% after just 8 weeks**
MAINTAINS SKIN COLLAGEN BALANCE
Increases skin procollagen levels by up to 65% after just 8 weeks**
Scientific documentation from recent clinical studies has greatly increased our knowledge of how we can most effectively protect the appearance of our skin by adopting a sensible diet and nutrition.
These studies that have recently been published in Skin Pharmacology and Physiology, an internationally well-reputed medical journal, show that the intake of specific collagen peptides has a significant positive effect on skin elasticity*, wrinkle volume** and procollagen levels**.
The collagen peptides investigated in the studies were produced using a special biotechnological process where natural, long-chain collagen is enzymatically hydrolysed into predefined short peptide chains with specific amino acid sequence, making them totally different from unrefined collagen peptides.
CLINICAL STUDY RESULTS:
SIGNIFICANT INCREASE IN SKIN ELASTICITY
Improves skin elasticity by up to 30% after just 4 weeks*
SIGNIFICANT WRINKLE REDUCTION
Reduces wrinkle volume by up to 50% after just 8 weeks**
SIGNIFICANT INCREASE IN SKIN PROCOLLAGEN LEVELS
Increases skin procollagen levels by up to 65% after just 8 weeks**
The studies were carried out to the highest quality standards. They are randomised, double-blind, placebo-controlled (RDBPC) human observational studies conducted according to the strictest Good Clinical Practice (GCP) standards.
These recent studies, together with previous scientific studies, have shown that collagen peptides only reaches the cells of the deeper layers of the skin optimally when they are produced by a unique method that ensures their effectiveness. These collagen peptides are produced using a special biotechnological process where natural, long-chain collagen is enzymatically hydrolysed into predefined short peptide chains having specific amino acid sequence.
* Daily intake of specific collagen peptides in a double-blind, randomised, placebo-controlled observational study of 69 people showed significant improvement in skin elasticity after 4 weeks, in some cases by up to 30%.

** Daily intake of specific collagen peptides in a double-blind, randomised, placebo-controlled observational study of 114 people showed significant
reductions in eye wrinkle volume after 8 weeks, in some cases by up to 50%. The same clinical study shows a significant (65%) increase in procollagen
levels in the skin after 8 weeks.

IMPROVED SKIN ELASTICITY IN WOMEN (50+):
These significant results from the double-blind, randomised, placebo-controlled observational studies are 
additionally supported by a number of previous in-vitro and in-vivo pre-clinical and clinical studies.
Studies have shown that collagen peptides are rapidly absorbed by the body in their natural peptide form[3],[4] and then transported to the skin[5] via the bloodstream[6],[7],[8],[9]. Studies also shown that collagen peptides may influence the production of the skin’s own collagen-producing cells, called fibroblasts[10],[11],[12], thereby stimulating increased turnover of collagen[2],[13],[14],[15],[16],[17] and other connective tissue components. Finally, scientific studies show that the intake of collagen peptides has a significant effect on the epidermis and dermis in the form of greater moisture balance[18],[19],[20], wrinkle reduction[2],[21],[22],[23] and improved elasticity[1],[18],[24].
