Is standing up a lot a good idea? The claimed health benefits for standing rather than sitting are quite impressive. According to juststand.org excessive sitting is causing “obesity, high blood pressure, diabetes, cancer, depression and the cascade of health ills and everyday malaise that come from what scientists have named sitting disease. ” Continue reading
The cost of making cosmetics is relatively low compared to what they sell for. They have what business people call a high margin. This makes the sector very attractive to entrepreneurs who scent an opportunity to make a lot of money. And some indeed do. But the high margins don’t always translate into high profits. Overall the return on investment for the cosmetic sector is respectable, but only a little higher than that for manufacturing as a whole. The reason is simple and you’ve probably guessed it already. You have to put a lot of effort into selling them. They all have to have some kind of unique selling point – or USP. Continue reading
There’s a new paper out with some numbers from dermatology clinics about reactions to methylisothiazolinone (MI). Dermatologists regularly patch test people to discover what they are allergic to. This involves applying a set of common materials that tend to provoke allergic reactions to the skin, and seeing which ones the individual reacts to. Continue reading
I get quite a few e-mails from people wanting me to promote their stuff on this blog. Most of them I politely decline. I don’t mind helping people, but I don’t want to clutter up my output with plugs for stuff of dubious relevance. So my rule is to say no unless it is something that is particularly interesting.

If you are interested in making your own cosmetics you probably don’t need me to tell you about Lisa Anderson’s Lisa Lise blog where she shares her knowledge and experiences making cosmetics on a small scale. Continue reading
Turtles mistake plastic bags for jellyfish
Christmas 2016 is over, and like a lot of people for me the next item on the agenda is getting rid of all the rubbish. I am particularly aware of it this year having read an article in the Biologist over the holiday by freelance naturalist Rajith Dissanayake. Despite the popularity of naturalness and general greenery we still produce one heck of a lot of plastic. I can certainly vouch for that as I have tried to squeeze of lot of it into my bin. Rajith quotes the figure that the average American produces around 2.5Kg of plastic waste per day, and us Europeans can’t be far behind.
Among the many things I try to cram into my schedule is a newsletter for people with sensitive skin. I am not very successful at doing this I am afraid, and I don’t get the newsletters out very frequently. But despite this I get a steady stream of people talking to me about their issues with reactions to cosmetics. In particular, to preservatives. And particularly in particular to methylisothiazolinone. Continue reading
Charcoal – Skin Purifier?

Is Exercise A Pointless Exercise?
I spend a lot of my time looking at claims made for various cosmetic products. People selling products are easily convinced of the benefits of those products, and are eager to share those benefits with potential purchasers. But it’s very often the case that the claims they make are based on the flimsiest of evidence. That is how the world works. The more you spend time looking at cosmetic claims, the more cynical you get about all claims across the board. So when someone tells me that exercise is good for you my first reaction is to be suspicious, even though this claim is often made, seems reasonable and doesn’t seem to be especially controversial. And it is one that I think most people assume is backed up by solid science. Continue reading
Do you need this stuff on your skin?
Caffeine has been a cosmetic ingredient for a long time, and you’ll find a jar of it on the shelves of most cosmetic development laboratories. There are three things it gets used for. There are the so called body sculpting products. The idea behind these is that you apply them to parts of your body that have more fat than you’d like. The caffeine stimulates fat burning, so you can get rid of the fat in the areas you don’t like it. Keep it up and you can change the shape of your body to something you like the look of. It is also used to improve the tone of the skin. It is supposed to stimulate energy production in the upper layers of the skin. This again uses the breakdown of fat, but in this case to release energy to improve the look of the skin. And finally it is used in shampoos to stimulate hair growth.
