Truth in Beauty |
A few days ago I hosted our second Truth in Beauty forum for senior health and beauty editors and members of the beauty press. Last time, our topic was absorption and Professor Jonathan Hadgraft discussed precisely what can (or, as it turns out, what can’t) penetrate through the skin. He successfully disproved the beauty myth that 60% of what we put onto our skin is absorbed into the bloodstream. The figure is more like 1-2% and even this small amount is doubtful (you can read more on this subject in our Blog archives from October 11th 2007, October 19th and November 9th 2006). This time we turned our attention on busting yet another pervasive beauty myth and one that has caused much scare-mongering and worry. The subject under scrutiny was how safe are the preservatives in skincare? You may well have read articles over the years with attention-grabbing, tabloid headlines such as Toxic Toiletries! or Killer Cosmetics! - especially when a group of preservatives called parabens are mentioned. So I invited leading independent dermatologist Professor Michael Cork, together with Dene Godfrey, a technical specialist with more than 25 years expertise in this field, to discuss the issues and examine the scientific evidence for such fears.
As it turns out, there is a danger with preservatives – but it is not what you might expect. The danger is in not using preservatives – especially in a formulation such as a moisturiser or body lotion which is a mix of oils and water. Any formulation that has water or aqua in its ingredient labelling needs to be properly preserved to keep it safe for us to use (and even those made without water may need preserving too). Professor Cork is a leading eczema specialist and his interest in this subject was triggered by patients who were using un-preserved natural remedies for their eczema and developing dangerously septic skin conditions as a result. One little boy very nearly died simply by using a non-preserved cream that was full of bugs on his damaged skin. Professor Cork showed plenty of gruesome slides to illustrate his point. His team are just completing a clinical study highlighting the perils of not using properly preserved skincare and this is due to be published in the next few months in a leading international medical journal. I’ll write more about this when it’s published.
So, as preservatives are so important for our health and safety, which ones should we be using? You may be surprised to hear that some of the safest and most effective are the family of parabens, first used in the 1920’s but largely out of favour due to incredible scare-stories about their safety. So, what is the truth here? Are parabens dangerous? Again, the answer may surprise you as it is a total and unequivocal No! As a result of our expert forum, I am now in the process of putting together a factsheet on the subject of preservatives in general - and parabens in particular. This will be available shortly on our website. In the meantime, I can tell you the following facts about parabens which might give you some reassurance if you have been worried by the many misguided media reports: Parabens are nature-identical ingredients first found in fruit where they occur as a natural preservative. You’ll find parabens in produce such as apples and blackberries and they are the main reason why blueberries stay fresh longer than strawberries. They first began to get a bad press following studies in 1998 which discovered that some parabens (no activity was discovered in methylparaben) have mildly oestrogenic properties, which could in theory have the potential to disrupt hormone activity. However, far from being perilous, these studies showed the very weak nature of this activity – weaker than, say, the oestrogenic activity from eating an apple and far less than the activity found in health foods such as whole grain cereals and soya. So although oestrogenic activity was established, it was proven to be so low as to be barely there. You could reasonably argue this actually proves the very safety of parabens. So what happened to cause the panic? The principle reason was the publication of a study in 2004, linking parabens in breast cancer tumours to the use of underarm deodorants. This study has since been found to be highly flawed and the professional review during our press forum showed it to be staggeringly inaccurate. In this particular study, all the samples studied, including 6 blank controls, were found to contain the same microscopic traces of parabens. In fact, in some cases, the blank controls (supposed to be just that – blank) actually had a higher parabens count than the breast tissue! Clearly a major flaw. This study does not prove any link at all between parabens and breast cancer. It also does not link deodorants with breast cancer either as the vast majority of deodorants and anti-perspirants do not contain parabens – and never have done, ever! Some have suggested that ingredients in underarm toiletries can ‘migrate’ into breast tissue, but this supposes firstly that they are significantly absorbed through the skin (they aren’t) and also defies basic anatomy. Both our blood circulation and our lymphatic circulation flow in the direction from the heart and down the arm, not the other way around. So unless these ingredients can swim upstream, they are not going to flow toward the breast. If present at all, they would be flushed in the opposite direction.
As a company, we have always taken the safety of all our formulations extremely seriously. You have probably read our ingredients policy which we highlight in each newsletter we send out. We carry out many highly stringent tests to ensure that we more than comply with the steps needed to make sure our entire range is safe to use. Actually for us, parabens are not important ingredients as we only use tiny traces in six of our formulations (we’ve found many other high quality preservatives over the years). So why spend time highlighting this beauty myth? I bother about it simply because it is wrong to create false fears. I now have no doubt about the safety of these naturally occurring group of ingredients and am angered by the needless worry caused by poor research by some - and deliberate scare-mongering by others. I strongly advise those with a lowered immune system, such as the young, the elderly, those with skin disorders or those being treated for conditions such as cancer to take great care and use properly preserved skincare. Preferably preserved with safe and effective ingredients – and that includes the parabens family. We must seriously hope that no-one ends up getting hurt by using toxic skincare – not toxic because it contains preservatives, but toxic because it doesn’t.
