Does Liquid Collagen improve your skin?
The collagen peptides used to create Absolute Collagen ® have undertaken comprehensive clinical studies in Japan and France – and both confirm the positive effect of taking hydrolysed collagen and the benefits on skin health.
The Hydrolysed Collagen and Skin Health 2009 Clinical Studies carried out in Japan and France confirm that taking 5 -10ml of hydrolysed marine collagen per day has moisturising and anti-ageing effects.
Fine lines, wrinkles and loss of elasticity are all signs associated with ageing skin. Additionally, environmental factors and a natural decline in cell renewal can contribute to other signs of ageing in the skin, including dull, rough or dry skin.
Maintaining the levels of collagen is paramount to improving the youthful, healthy appearance of the skin. Glycine, proline, alanine and hydroxyproline are the main constituents of collagen and prevent skin ageing.
A growing body of research is showing that nutricosmetics (stuff that you ingest, rather than apply) can contribute to healthy skin. Whilst topical creams can affect the skin condition on the outside, nutritional supplements taken orally can have an impact from within the skin.
To access the efficacy and acceptability of the hydrolysed marine collagen peptides – two double-blind, randomised clinical studies versus placebo were carried out on 80 healthy female volunteers between the ages of 35 and 59.
These studies were performed according to regulations on clinical studies and approved by the local Ethical Committee. Additionally – each subject was placed, for at least 30 minutes, in a room with controlled temperature and humidity prior to each measurement.
The two studies were as follows:
STUDY 2008 – A00654 - 51: This evaluated the effects of oral intake of hydrolysed marine collagen peptides on the cutaneous (relating to or affecting the skin) properties versus placebo. The study was conducted in Lyon, France, by DERMSCAN on 47 women from 35-55 years old for 84 days during winter where each ingested 10g of marine collagen.
STUDY YNTKK – 2008 – 4144: Double-blind placebo-controlled trial of oral supplementation of collagen peptides conducted in Tokoyo, Japan, by SOUKEN on 33 women from 40 to 59 years for 8 weeks during winter, where each also ingested 10g of marine collagen.
The results were then measured – skin hydration measurements were taken with a Corneometer ® CM 825 device. This instrument determines the humidity levels of the most external skin layers.
To measure the anti-ageing effects, polymer silicone skin prints were taken from the studied area before and at each time of measurement then studied using the Skin Image Analyser® or 3D roughness analyser. The replica is then observed with a digital camera linked to a computer – where a 1cm2 area is studied.
As well as these studies; the volunteers’ perception of how hydrolysed marine collagen performed was also an integral part of the study.
So what did the results show? 91% of the volunteers taking marine collagen saw their skin hydration increase after 8 weeks daily usage.
The number of ‘micro furrows’ in the skin significantly decreased with the use of hydrolysed marine collagen – 26% better in 12 weeks.
Conversely, the number of deep wrinkles significantly INCREASED in those taking the placebo for 12 weeks.
Skin suppleness increased by 19% in the hydrolysed collagen group – and there was visual evidence of a reduction in the depth and width of wrinkles.
Additionally – volunteers reported better moisture levels after cleansing and removing make-up, and an increase in skin hydration with 68% of the women saying their skin was less dry.
Those taking the marine collagen also reported improved skin suppleness, skin tonicity and skin brightness compared to those on the placebo.
NO adverse effects were reported in the women taking the marine collagen.
These studies therefore clinically show that ingesting hydrolysed marine collagen daily will:
- Improve skin moisture levels
- Improve skin smoothness by reducing the number of micro-relief furrows
- Prevent the formation of deep wrinkles
- Improve skin suppleness
To conclude - Absolute Collagen® works!
