Nutraceuticals and skin appearance: Is there any evidence to support the claims?

Posted 15 February 2018

“The rise of the nutraceutical market, specifically oral nutrition supplements claiming to improve skin appearance, is striking. This paper aims to examine the published scientific evidence for beneficial effects of nutraceuticals on skin appearance. An overview of skin physiology and intrinsic and extrinsic ageing is provided which underlies the potential physiological processes nutraceuticals purport to counter”.

“Current evidence for those without existing authorised claims (e.g. green tea extract, pomegranate extract, carotenoids, evening primrose oil, borage oil, fish oil, collagen and co-enzyme Q10) is reviewed, focussing primarily on evidence from randomised controlled trials where available, in relation to skin parameters including wrinkles and hydration”.

A dozen facts about Solal and their “critics” – subsequent . .

A posting on Quackdown! (How Solal Technologies uses legal threats to stifle legitimate criticism) resulted in vitriolic comments from Solal's Brent Murphy and Colin Levin, directors of Solal.

Harris Steinman responded to these comments with a posting on the same blog (A dozen facts about Solal and their "critics"). Colin Levin, taking umbrage, commented on this posting making a number of significant points which Harris felt obligated to comment on.

Harris writes:

"It is hard to know how to make any sense of the "arguments" in Colin Levin’s numerous postings. In my view, his statements are rendered nonsensical when considered in the light of several well-reasoned deconstructions of Solal’s claims and arguments on this blog and on CamCheck."
