30 Toxic Chemicals to avoid in Skincare products

Have you ever taken a really good look at that long list of ingredients on that shampoo or foundation you bought?

Like a REALLY good look?

No?

Ok, go to your dressing table right now and pick up just one tube or bottle of whatever you find there and read the ingredients list on the back. Go on. I’ll be waiting right here.

Did you see a couple of unfamiliar words on that list, some of which you couldn’t even pronounce? Do you even know how much of each ingredient is in the product or even, how those products could affect your skin or your body?

No? Don’t worry. You aren’t alone. Analyzing an ingredient list is incredibly complicated due to the sheer number of ingredients listed (and many hidden ones!). How they are formulated, the effects these formulations have on our skin and if they even work aren’t clear. Even products that are “natural” or “organic” have ingredient lists that are difficult to decipher.

To kickstart the process for you and make it all simpler, I’ve compiled a list of the common potentially harmful chemicals in your beauty products, its uses and how it could possibly affect you.

Read on!

Which toxic chemicals in our cosmetics and skincare products do we need to avoid? These dangerous beauty products are harmful to our skin and body. Let's find out which ones they are.

As more research is done on this, more will be known about these chemicals and the effects of these products on our body. Whilst there has been an increasing amount of information available to the public in recent years,  it’s still very early days. Research takes a lot of time and it won’t be a few years til we get the full picture.

Deciphering ingredient lists aren’t easy and takes a lot of practice and research. I think that it’s extremely difficult to avoid ALL of these ingredients. A couple will be present in any one product in unknown percentages.

So, for now it’s just best to keep informed and aware – until safer alternatives appear in the market.

Steps you can take:

  1. Always read the chemical ingredients in your beauty products before you buy them. Keep a handy list of these chemicals to avoid in your phone or wallet, so you can refer whilst making purchases
  2. For all your products, you can check the ingredients against the EWG Cosmetics Database or Paula’s Choice Ingredient Dictionary. Those provide toxicity ratings of many types of chemicals, and descriptions of the side effects.
  3. There are apps like the Think Dirty App where you can scan products and get quick infor on the ingredients. I don’t know how effective these apps are though, as I’ve not tried them. So if you have, let me know how it worked for you.
  4. Try exploring natural beauty products. There are lots of good brands around that use ingredients like essential oils for instance. You will see sites and magazines pushing certain natural/organic products, but always read around and try out samples before committing to a big purchase. Certain companies like to claim their products as natural but, it might not actually be.
  5. Different countries have different ways of classifying these chemicals, for eg, the FDA (USA) and EU (do an ingredient search and some papers will pop up) have different classifications on toxin levels allowed in consumer products. So check where your cosmetics are produced and what is sold in your country.
