Nanotechnology Makeup: Small, Yet Potentially Dangerous

As cosmetic aficionados, we’re all guilty of waiting for the “next big thing”; that product which is going to make our lives a little easier, hide those blemishes better, fill in those lines more effectively, and make us all look that little bit more stunning (than we usually do!). Nanotechnology, the use of microscopic nanoparticles in cosmetics, has been advertised to the world as the next revolution in makeup and skin care, it’s the next big thing we’ve been waiting for – perfectly safe for human use.

But is it?

Let’s take a look at just what nanotechnology is, how it’s used in the cosmetics industry, and why you should make sure that you only use products which contain no nanoparticles.

What is Nanotechnology?

Nanotechnology has been around for decades, but the technology is so delicate and complex that it has taken a long time for engineers, scientists, and manufacturers to figure out cost effective ways of using it. Nanotechnology itself refers to anything which is constructed at a molecular level. The miniscule scales at which nanotechnology operates are mind-boggling. This simply means that materials are made, in this case makeup, atom by atom, constructed in a more rigid and controlled way, at least that’s the idea. It has literally thousands of applications in material construction and could pave the way for a revolution in the way any product could be made in the future.

A product created through nanotechnology can be made from the ground up without traditional methods of putting together various naturally occurring and synthetic ingredients. In theory, this means inventors and manufacturers should be able to make new types of materials with specific, efficient uses – like makeup which will never run, lipstick which can last for days, moisturizer which will keep your skin smooth for a week at a time, and foundation which needs only one thin layer to cover any blemish.

Sounds great doesn’t it? Unfortunately, the reality is very different from the potential of this technology. There’s no doubt that nanotechnology is an exciting innovation, but should a process used to make metals and plastics really be applied to your beautiful skin?

What does the evidence suggest? Should you keep using nanotechnology products?

To answer that question, let’s look at the way current products use this technology.

How is Nanotechnology Used in the Cosmetics Industry?

Nanoparticles in cosmetics aren’t exactly a new thing and in recent years more and more cosmetics are wearing the “nanotechnology” badge with pride, but did you know that many cosmetics use this technology already and don’t even have to acknowledge it? This is happening all the time because the industry isn’t regulated properly yet, which often happens when new technologies are brought into use. The problem is that this doesn’t protect the consumer from being able to choose what products and ingredients they subject their bodies too. You should be able to make an informed choice about the manufacturing processes used in your make-up, but right now it can be very difficult to do that.

You probably think you haven’t ever used a product which has nanotechnology in it, but the sad truth is that you most likely have already. The sheer volume of products which use nanotechnology in their construction are worrying, especially when you take into account the growing evidence which suggests that nanoparticles could be hazardous to your health, but more on that in minute.

For now, prepare yourself for a shock. You’ll find nanotechnology in many brands of the following:

  1. Moisturizer
  2. Soap
  3. Deodorant
  4. Toothpaste
  5. Shampoo
  6. Sunscreen
  7. Hair Conditioner
  8. Perfume and Aftershave
  9. Aftershave Lotion
  10. Anti-Wrinkle Creams
  11. Nail Polish
  12. Lipstick
  13. Eye Shadow
  14. Foundation
  15. Blush

And that isn’t even a comprehensive list! There are literally hundreds of day-to-day products using nanotechnology, and there are very few regulations around the world forcing manufacturers to advertise that fact. Imagine if you had a nut allergy (some of you probably do) and food companies were allowed to omit peanuts from their ingredients lists, even though they use them. How would that affect you?

You have to be able to know what you are putting on your skin, as this is absorbed directly into your body. The cosmetics companies should make it quite clear exactly what is in their products and how the ingredients are manufactured, but apart from a small merry band of ethical cosmetics producers, very few do.

Why Does The Cosmetics Industry Use Nanoparticles?

The processes involved have become so cheap that major cosmetic companies including L ‘Oreal, Avon, Lancome, The Body Shop, and Revlon all use nanoparticles when making their products. It’s all about profit, and while various scientific studies have shown that nanoparticles may be dangerous when used in cosmetics, the industry still does not listen. Why? Because most are only interested in pushing production costs as low as possible, while benefiting from a “new technology” which their marketing departments can advertise as “revolutionary”, encouraging people to buy without realising the danger they are putting themselves in.

The problem is that more testing needs to be done to understand the long term effects of nanoparticles in cosmetics when applied to the skin, and right now we only have a few studies. What’s worse, those studies specifically point out how detrimental to a person’s health nanotechnology seems to be.

But That Sounds Dangerous?

You bet it’s dangerous!

In recent years new types of nanoparticles have been continually used in all manner of cosmetic products. One example is silver. It might look good on a piece of jewelery, and yes it does have antibacterial properties, but there is increasing evidence that when used in cosmetics it could be toxic to human beings and the environment.

Two of the most common nanotechnology ingredients being used in cosmetics today are titanium dioxide and zinc. Both of these are metals and at such tiny nano-scales, the particles are easily absorbed into the bloodstream and around the body. There is an increasing amount of evidence that these materials can badly affect skin, damaging DNA and cell function by the production of free radicals when exposed to UV light – part of the day-to-day light spectrum we are all exposed to when we go outside. Put it this way, would you eat metal? No, but you’re still absorbing particles of it when using these products!

If you are willing to put the risks aside, then think about the affect on any children you might have down the road. A recent study has shown that titaniam dioxide is passed onto the offspring of mice resulting in potential brain and nerve damage, not to mention affecting the ability of males to produce sperm later in life. Now, you might think “well, that’s in mice”, but the chances are it would occur in all mammals, humans too! That’s why we at La Mav refuse to use nanoparticle-size titanium dioxide in our products.

Another type of nanoparticle seen in many cosmetics is the “Fullerene”. A fullerene is a carbon ball-shaped particle which is of particular concern. Studies are showing that when applied to the skin, these particles can be easily absorbed into the body. These particles have been seen to cause severe brain damage in some animals and even kill others. In humans they have been linked with liver damage and may even affect the human body’s immune system.

In summary, nanoparticles in cosmetics & skin care appear to be very dangerous, and so consumers should educate themselves as to which products contain them, and which do not.

So, What Now?

Due to cosmetic companies not having to declare that their products use nanotechnologies/ nanoparticles in cosmetics during the manufacturing process, the only option open to an informed consumer like yourself, is to use products which specifically state that there are no nanoparticles present. Only then can you be certain that you are protecting your health and your skin, by avoiding subjecting your body to the dangers of nanotechnology in cosmetics. It’s down to you to make an informed choice.
