12 known-to-be harmful beauty ingredients


When I learned about the toxins and harmful chemicals in cosmetics & personal care products, I was really surprised!

I went down a rabbit hole of finding information about how toxic ingredients were allowed in our beauty products (and household cleaning products).

This led me to throw out bags and bags of makeup, hair care, personal care products, and body lotions.

I didn’t want any product that wasn’t clean to touch my hair, skin or teeth. I became very strict with what I used but long term, I couldn’t keep up with this way of life.

Products that are super clean and pure are more expensive, and it’s not always practical to spend lots of money on a single item. 

What is possible for me is to purchase non-toxic products as much as I can.

I try to be mindful of what I spend my money on and always look for organic, non-toxic products first.

I abide by the 80-20 rule which I do for eating as well:

80% of what I use is clean + green, the other 20% is conventional products

I think it’s important to be aware of what you are putting on your skin and know what to absolutely stay away from as much as you can. 

When first setting out on your clean beauty journey, a good habit to develop is to simply  check the ingredients listed on the cosmetics and skincare products you are using and start by looking out for the following 12 harmful ingredients:

The body’s immune system recognizes changes caused by sun exposure as a foreign threat. The body produces antibodies and attacks, causing a reaction.
