Higher skin elasticity1

The first study with 69 women aged between 35 and 55 years revealed significantly higher skin elasticity – up to 15 % – compared to placebo treatment. This effect could be measured after just 4 weeks of treatment and persisted after 8 weeks of oral administration. Another 4 weeks after the last intake of the product, application still showed higher skin elasticity levels than in the placebo treated group.

Reduction of wrinkles2

The second study with more than 100 women aged between 45 and 65 years shows that the oral administration of collagen peptides significantly reduces wrinkles after 4 weeks and leads to a significantly higher skin collagen concentration.

Significant decrease of cellulite score3

A double blind, randomized, placebo controlled study with 105 women aged between 25 and 50 years shows that the daily oral intake significantly decreases the cellulite score. The effect was measured after 3 and 6 months supplementation. It has a beneficial effect on skin extracellular matrix and restores the normal structure of the dermis and subcutaneous tissue. Supplementation also reduced the waviness of the skin, with first results visible after 3 months, but more pronounced after 6 months. With a daily dose the appearance of cellulite women with a BMI < 25 was significantly reduced.

As part of the study, changes in the dermal density were investigated. The two ultrasound scans show side by side the skin of a participant in the placebo group compared to the skin of a participant from the collagen group. The increase in elastin and collagen is clearly visible.

Promoting growth and health of fingernails4 

The different positive effects of collagen peptides are shown in a recent study. The study shows a decrease of cracked and/or chipped nails after 2 months of treatment, reaching a decrease of 42% after 6 months. Compared to the control group, the nail growth speed is increasing. It led to a statistically significant improvement in nail growth after 3 months of treatment. At the same time, there’s a notable improvement in nail peeling and a clearly decreased nail edge irregularity. 80 % of the patients were completely satisfied and satisfied with treatment. 75 % of the women perceive their nails as longer, 71 % said their nails grew faster and became longer.
