Colladeen® Visage provides both anthocyanidins and lutein, at levels that match previous research in to their role in skin health. But we wanted to prove it for ourselves and commissioned two placebo controlled studies, both with 60 healthy subjects, the first ran for 12 weeks and the second for 24 weeks. The exciting results are explained below.

Elasticity and firmness
What we did in the study
In both studies we measured the level of skin elasticity of the 60 adults, aged 50 to 70 years old, at the start of the studies using a validated method involving an instrument called a cutometer. Half the group then took two tablets of Colladeen® Visage a day; the other half took identical looking dummy placebo pills.

We then measured skin elasticity at 4 weeks, 8 weeks and at 12 weeks (also at 24 weeks in the second study) and compared the results between the two groups.

What we found
The group taking Colladeen® Visage showed a statistically significant increase in skin elasticity compared to the group taking the placebo by the end of 24 weeks. Measurements at 4, 8 and 12 weeks show that the improvements were increasing over time and were statistically significant at 12 weeks.

What this means
This shows that in a mixed group of adults Colladeen® Visage can bring improvements in skin elasticity and that these results are seen after a 12 week period. Of course the results will vary greatly between individuals, and will be determined by their age, the level of pre-existing sun damage, skin type and their diet. When collagen and elastin production declines the dermis will start to lose its elasticity and become thinner. There is also a reduction in hydration caused by a decline in the network of tiny blood vessels. As a result folds, or fine lines, start to appear on the skin surface and are initially only visible when a muscle moves. But these lines develop into wrinkles that eventually turn in to the dreaded furrows, which are permanently visible.

Wrinkles
What we did in the study
The two studies both involved 60 adults, aged 50 to 70 years old and lasted 12 and 24 weeks, with measurements taken at the start and at regular intervals and at the end. Half the group took two tablets of Colladeen® Visage a day; the other half took identical looking dummy placebo pills.

We used a test called a profilometry which involves taking a flexible cast of an area of skin and we used the crows feet area around the eye in this study. The cast is then scanned to identify the depth of wrinkles and can be compared with casts taken from the same person at later dates..

What we found
There was a reduction in wrinkle depth seen in the group taking Colladeen® Visage, which was measurable at 4 and 8 weeks and by 12 weeks there was a statistically significant result with wrinkle depth reduced by 6% and by 24 weeks some subjects had double this level. No improvements were seen in the group taking the placebo.

What this means
This shows that in a mixed group of adults Colladeen® Visage can reduce the depth of wrinkles significantly by 12 weeks and these results continued to improve up to 24 weeks.

Of course the results will vary greatly between individuals, and will be determined by their age, the level of pre-existing sun damage, skin type and their diet.

Sun Protection
Colladeen® Visage put to the test!
This product provides a high potency dose of anthocyanidins and lutein at levels that previous scientific studies showed would provide some protection against sun damage. We set out to see if Colladeen® Visage could offer the same benefits!

How the test was conducted
We used the same tests as used to determine the SPF level for sun creams. The test measures the MED, (Minimal Erythemal Dose) and it was carried out on the same two groups of 60 adults. At the start of the two studies each person has UV light shone on small patches of skin for increasing lengths of time. The next day the patches are examined to determine the shortest exposure time that caused reddening for each person. As with the other tests measurements were taken at the start then at regular intervals and at the end. In both studies half the group took two tablets of Colladeen® Visage a day; the other half took identical looking dummy placebo pills.

What we found
The average MED increased significantly in the group taking Colladeen® Visage and the effect increased with time. When the measurements taken at 12 weeks were calculated as an SPF, or sun protection factor, just as they would be for a suncream, we found that on average an SPF of 10 was achieved. At 24 weeks this had increased to an SPF of 15.

What this means
Taking Colladeen® Visage for 12 weeks gives an SPF of 10, and by 24 weeks it will be an SPF of 15, although this is an average result and will vary between people. So all day long your skin can potentially have some protection against sun damage even if you are not wearing a sun cream. But please note: Colladeen® Visage should only be used as an additional protection against sun damage. It certainly does not replace your normal sun protection regime.
