Retinol is one of a number of vitamin A derivatives that is used in pharmaceutical and cosmetic products. When I wrote about it last time I glossed over one of its drawbacks. Along with the rest of the vitamin A family overdosing can have some very serious health issues. Vitamin A is fat soluble and as such it is possible for it to build up in the body’s fat deposits. In extreme cases this can lead to birth defects. Continue reading
A question from my first Twitter chum, Musicalhouses.
Dear Colin, How can we guess how much retinol there is in a skincare product? It’s quite hard to get a percentage ge since companies don’t disclose this. In particular, I’m looking at the Hada Labo Retinol Lifting and Firming Lotion (Ingredients: water, butylene glycol, glycerine, PEG-20 sorbitan isostearate, caprylic/capric triglyceride, methylparaben, PPG-10 methyl glucose, ether, sodium Hyaluronate, triethanolamine, Carbomer, hydroxyethylcellulose, tocopherol, BHT, disodium EDTA, hydrolyzed collagen, hydrolyzed soy protein, limnanthes alba (meadowfoam) seed oil, retinyl palmitate, helianthus annus (sunflower) seed oil, sodium Everglades Hyaluronate, zea mays (corn oil) thioctic acid, beta carotene), since retinol appears all the way down there in the ingredients list and it doesn’t have the characteristic smell or colour (white to off-white yellow) of most retinol-containing products I’ve used in the past. Also, I’d be interested in knowing any rules of thumb you have for guessing the % of a skincare ingredient given how far up or down the ingredients list it is. Thanks!
Retinol is one of the few so called active ingredients used in cosmetics that actually does something. But as a savy consumer and beauty blogger (see http://musicalhouses.blogspot.co.uk/) Musicalhouses knows you have to have enough to have an effect. Continue reading
What is Bio-Oil?
The cosmetics and personal care industry is a huge behemoth which takes in and spends billions and billions every year. A lot of its activity is focused on sales and marketing with the ultimate objective of getting money out of your pocket and into theirs. Sometimes this involves providing you with a good product that meets a genuine need or gives you a real benefit – but profit is the motive.
But sometimes a product becomes successful for no other reason than that people like it, tell their friends about it and create a word of mouth reputation. One example of this is the product Bio-Oil made by a relatively small Swiss company. The company makes a range of claims for their product, but the one that seems to have struck a chord is that it works for stretch marks.
I reviewed the famous Boots No 7 Serum back in 2007 when it was in the news last time. It is getting widespread media coverage again now that positive results of a proper a trial published in the British Journal of Dermatology – a highly respectable scientific journal. You can read the full publication here. (Thanks to my Twitterchum BordadoIngles for the link).
The paper is extremely well written with a very good introduction that summarises the current state of knowledge of anti-ageing ingredients used in skin creams. pointing out that the only really well substantiated one is retinol. Reading the paper was also the first time I have read that the name of the product has been changed to No 7 Protect and Perfect Intense Beauty Serum. It looks like the marketing wonks have been busy as well.
We all get old. As we get older get wrinkles. None of us want to look old, so we are open to suggestions for how to get rid of them. But we are all intelligent enough to realise that there is a limit to how much we can cheat the clock. So as someone who works on this kind of thing, what have I found that really works?
