Clinical study
Our manufacturer, striving to ensure the highest standards, conducted a clinical trial, and we would like to share the results with you.
About
In this single-centered, randomized, double-blind, placebo-controlled clinical study, the safety of collagen consumption and its anti-aging effects were evaluated. Namely wrinkles, skin elasticity and hydration. 50 healthy females aged 45 to 60 years old were treated with l0g a day of our collagen or placebo for 12 weeks. The results are below.
Safety
Safety was assessed by adverse events, vital signs, anthropometrics, complete blood count, and liver and kidney markers. The collagen was well tolerated. No difference was found in the number of health incidences between treated and placebo throughout the study as well as no serious adverse event was reported.
Consumers evaluation
All participants performed skin quality evaluations during the study. Significant improvements were reported at ending compared to beginning of study in wrinkles, elasticity, hydration, firmness, and radiance. In all assessments, participants treated with our collagen consistently reported higher improvements compared to those with placebo, ranging from 14 to 25%.
Skin Quality Improvements of our collagen above Placebo:
Wrinkles 15%
Elasticity 23%
Hydration 14%
Firmness 25%
Radiance 22%

Effect on skin – wrinkles
Within the group, participants had a statistically significant 35% reduction on the right face and a significant 17% reduction on the left face in the wrinkle scores. This result is possibly due to the
fact that the left face of the study population was more photoaged than the right, hence the difference in efficacy compared to placebo was detectable but less significant. Longer treatment is suggested to show more significant efficacy on the left face. These effects on wrinkles are much higher than clinical results of similar ingredients. A possible reason is because of the especially high concentration of certain amino acids such as glycine, proline, and hydroxyproline (which account for more than 50% of total amino acid content of collagen) that are important in maintaining and promoting antioxidant activity in the human body.
Effect on skin – elasticity
Cheek skin elasticity was significantly improved within the first 6 weeks of supplementation with our collagen in participants 45-54 years of age. The effect seems to level with no significant difference between week 6 and week 12. Overall, cheek skin elasticity was significantly improved by 10% from baseline to end of study in these participants. Older participants may need to take collagen longer to see the same effect. Other studies that saw significant improvement in the group treated over placebo used collagen in combination with other ingredients such as vitamins A, C, E and zinc or astaxanthin. Likewise, our collagen can be combined with other ingredients for faster results in improving skin elasticity.
Effect on skin – hydration
Although not statistically significant, participants supplemented with collagen showed a 3% increase in cheek skin hydration whereas participants in placebo showed a 5% decrease after 12 weeks. According to consumers' evaluations, skin hydration in the collagen group is 14% higher than in placebo after 12 weeks of use (see table 1). The collagen can be combined with other ingredients such as hyaluronic acid for faster results.
