Lies, damned lies and the dubious world of cosmetics advertising

Let's face it, most people's ability to analyse statistics is pretty poor. In fact we can consider ourselves lucky if we know anything beyond mean, median, and mode, and certainly left- and right-skewing isn't a popular topic of conversation. Perhaps that's why the multi-billion pound global beauty industry uses such bizarre examples in their advertising, on the grounds that few punters will understand any of it. Not being a regular reader of women's magazines most of what I pick up is via flicking between TV channels, occasionally spotting some famous actress or supermodel accompanied by such interesting statements as '83 out of 114 women agree' (although I made that one up).

Isn't it fairly obvious that there are two concerns here? Firstly, the figures aren't easy to simplify to lowest common denominators, lacking the nice, rounded character of say, 80 out of 120. Secondly, the numbers are so small. Following the MMR scandal and its case study group of 12, surely few could think such a low sampling as my fictional 114 could be taken as a worthwhile trial? Yet I cannot think of a single example from this sector where the study (if we can call it that) exceeded 200. Are the numbers parts of some elaborate in-joke by the cosmetics industry or are they based on genuine data, in which case are the polls conducted by marketing agencies with very short attention spans?

Despite recommendations that the UK's Cosmetics, Toiletries and Perfumery Association members are meant to adhere to, outsider knowledge of what the beauty product multinationals get up to is minimal. Most companies test their products on other animals before moving onto humans, but how scientific is the research conducted on the latter? If the advertising figures are based around how punters ‘feel' (surely a profoundly subjective word), there is more than a hint that the research hasn't involved standard scientific procedures such as double-blind or placebo experiments.

And of course, no information is given as to where the punters were found: in statistical terms, how random was the sampling frame? So despite the sophisticated research that often goes into developing the products, their marketing appears to offer the antithesis in the form of essentially worthless polls and neo-scientific yet nonsensical compound words. Even innocent-sounding phrases such as "natural looking skin" aren't worth anything; after all, isn't all skin natural looking if it is free of make-up and cosmetic surgery? A combination of genetics and lifestyle - I really hate that last word - are responsible for the condition of your skin, with few people nowadays failing to recognise that sunbathing smokers are unlikely to retain a youthful complexion even with the aid of pots of ground up chicken feet and the food of queen bees.

That the product manufacturers have kept one step ahead of the cynicism is perhaps not all that difficult to explain. Our popular culture and media are obsessed with youth (which is nothing new - take classical Greece as an example) but at least modern legislation prevents the use of obviously insane ingredients. After all, it is far less than a century since radium was used in hair cream and toothpaste. It seems we may have slightly less gullibility than previous generations, yet even a temporary improvement in our appearance is inviting enough to fork out vast sums of money for.

But is all this about to change? In the last few years a radically different range of beauty products has been in development that appears to be rather more than usual temporary Polyfilla. Trials are taking place involving skin cream that may be an early form of "cosmeceutical", able to restore the structure of skin rather than simply obscuring aging and damage. As for me, I'm watching with interest the research into mimicking the effect of enzymes that prevent loss of hair colour - or even reverse it. What, vain? Me? Surveys suggest that only 1 in 10 men don't mind the natural greying process. Okay, I made that one up too!

How to look smart: textiles with intelligence

Although cybernetics, the truly personal interfacing of man and machine, has long been discussed in both fact and fiction, far less attention has been paid to futuristic clothing, Star Fleet velour and shiny foil suits aside. The past decade has seen a proliferation of technologies aimed at developing clothing that does more than just provide comfort and display. The creation of smart textiles that react to both external environmental factors and the wearer's body promises a wide range of uses, from health and medicine, via sports, to ultra-portable information technology.

In 2008 the smart fabrics industry in the European market alone was estimated to be worth over three hundred million Euros. To this end, the European Union created a research cluster with the quasi clothes-related if slightly tortuous acronym SFIT, or Smart Fabrics, Interactive Textile. With a growth rate forecast at 20% per year the sector shows great promise - and how much of it will revolve around consumerist infotainment gadgetry is anyone's guess. As an example of what is already available, the British company Peratech produces a wide range of electro-conductive smart fabrics under the Elektex banner. MP3 players and BlueTooth devices are amongst those incorporated into their clothing, and I assume it won't be too long for some form of television or viewing capability is built in, perhaps utilising sunglasses or head-up display technology.

The increasing miniaturisation of electronics and materials in general will undoubtedly lead to clothing and accessories constructed of elements arranged at a nano level. Recent developments in computer interfacing, such as the roll-up keyboard, suggest it may not be too long before people are wearing items more intelligent than they are (although in many cases that wouldn't be too difficult!) Much has been written about technology at the nano scale, including research into creating nano-bots that can be injected into the human body to destroy infections or fatty deposits. At a rather less invasive level, it is easy to see that smart fabrics could be developed for the slow release of pharmaceuticals or to monitor heart rate, respiration etc. The New Zealand company Zephyr have already developed two products: the kinky-sounding bio-harness and the shoe pod, both containing sensors woven into the textile. When combined with data storage components the products can record physiological information. No doubt the military are keeping as keen an eye on these developments as much as professional sports concerns.

Speaking of the armed forces, in February this year the UK's Ministry of Defence awarded a research grant to the British firm Intelligent Textiles Limited with the aim of developing fabrics that could back up if not replace military field equipment such as radios. Combined with innovations such as the aforementioned roll-up keyboard it seems strange how late has attention been paid to these developments. Clearly, there are benefits for many areas, although whether companies will persuade their executives to include such items in their travel luggage may appear a step too far in the work-life balance threshold.

Back on the health front, the simplest use of smart materials may be fabrics able to aid allergy sufferers, or at least warn them of impending doom (I would dearly love a built-in pollen detector!) Research is also being carried out into fabrics that change colour if they reach a pre-set level of ultraviolet radiation exposure within a time limit; clothing with this non-permanent photo chromic technology might prove to be of immense value to the Australasian market, with the southern ozone hole predicted not to heal for at least half a century.

One area you might expect to see high-tech developments, that of astronaut clothing, has received relatively little public attention apart from EVA (i.e. spacewalk) suits. In the 1970s the Soviet Union developed the elasticated Penguin suit to help cosmonauts exercise their otherwise wasting muscles on long-duration flights. A more high-tech approach is now being developed since the European Space Agency engaged the Danish firm Ohmatex last year to design and manufacture a 'smart sock' to monitor muscle activity via built-in sensors.

Another European venture is the international Biotex project, which aims to develop fabrics with built-in biosensors that can analyse the pH levels and mineral balance of the wearer. One civilian use would be analysis of energy expenditure, extremely useful for those on diets - as in, yes, you can have another chocolate biscuit, you've used up extra calories today. Indeed, the American NuMetrex range of clothing already has something along these lines, along with heart rate and pulse monitors, although from what I've read they are as yet of more use to healthy people than those with cardio-vascular conditions.

On a slightly more esoteric note, transatlantic research teams involved in the recent 2010 Congress of the Humanities and Social Sciences have developed a concept for interactive clothing that responds to the wearer's emotional as well as physical state. The Wearable Absence project aims to deliver complex, personalised audio-visual content when certain physiological conditions are met. Although early days, this could prove to be incredibly useful technique for therapy on the move.

However, it is not all plain sailing for the smart textiles industry: recent studies have suggested that certain smart materials incorporated into clothing, from the tiny silver particles used in anti-odour socks to more exotic substances such as carbon nanotubes, may pose long term health or environmental risks. There have even been discussions in the European Parliament Environment Committee for a ban on some of these materials as part of a wider interest in their adoption in various types of consumer goods.

But ultimately, smart materials are just too good to be abandoned altogether, even if there is a multitude of teething problems ahead. But once these issues are ironed out (geddit?) many of us will no doubt wonder how we ever managed to live without clothes that could power our personal entertainment and phone devices, supply satNav data, monitor our vital signs, offer emotional support in times of stress, and be of course completely self-ironing.
