Does collagen really work?

Studies on Kollo’s key ingredient, Type 1 marine collagen peptides, suggest that taken daily it may help to slow the signs of ageing and improve overall skin and joint health.

Consumer Panel Study, Japan

A panel of 52 healthy women with normal skin, aged between 20 and 60 years old, orally took this type 1 collagen every day for four weeks. Over the course of the study, they answered a series of questions, which included state of the skin and state of the joints during and at the end of the study.

Collagen significantly improves form factor in skin relief after 6 and 12 weeks

The Results

Consumers reported improvements in wrinkles and overall skin appearance (skin firmness, hydration, skin radiance and brightness) after two weeks. The study suggests that oral daily intake of 10g of this type 1 collagen can counteract skin ageing and benefit skin health.

Consumer reported improvements in wrinkles skin appearance after 2 weeks of daily oral intake.

Consumers also reported a positive impact on their joints after four weeks, with a noticeable decrease in joint pain. 

Consumers reported a decrease in joint pain after 4 weeks of daily oral intake. 

Clinical Study, France

Forty healthy female volunteers aged between 54 and 63 were split into two groups of 20. One group took an oral dose of this type 1 collagen  in liquid before breakfast for 12 weeks. The other group took a placebo. Researchers then performed analysis via a number of methods:

-   A cutometer, which uses a suction method to depress the skin then record the time and quality of its ability to return to normal, was used to  measure skin elasticity.

-   A corneometer, which measures the moisture levels in the outer dermal layers, was used to measure skin hydration.

-   Skin images were analysed using dedicated computer software to perform 3D analysis of wrinkles.

Subjects were also surveyed for their response to the question, "Would you say that the treatment you underwent has reduced the wrinkles on your face?". Investigators and subjects separately answered the question, "Would you say that the treatment you underwent is globally effective in reducing signs of ageing in the face."  

The Results

At the end of the study, lines around the eye (crow’s feet) indicated a significant smoothing in the overlap of the skin and a significant reduction in skin wrinkling. No effect was observed in the placebo group. The clinical score of wrinkles, assessed by the Investigator, decreased significantly between week 6 and week 12. The clinical score remained unchanged for the placebo group. 

Results show a significant (-9.37%) reduction in skin wrinkles after 12 weeks. 

Skin hydration also showed significant improvements in the type 1 collagen group, with hydration levels increased by 22.8% from day one of the study.Skin elasticity showed major improvements at both week 6 and week 12, with a +27.2% increase in hydration by week 12. 

Results show a significant (+22.8%) improvement  in skin hydration after 6 & 12 weeks. 

Results show a significant (+27.2%) increase in skin elasticity at  12 weeks
