Damaging Ingredients To Avoid In Your Skincare

When shopping for skincare products to add to your routine, it can be challenging to know what’s good and what’s not. When you look at the ingredients on the label and see an ongoing list of words you can’t pronounce, it’s never a good sign. 

However, we’re here to help you make wiser skin care decisions. 

We put together a list of the most damaging skincare ingredients to avoid if you want to build a clean skincare routine that benefits you and helps you see results.

Here’s everything you need to avoid:

DEA, MEA, and TEA 

These ingredients are colorless liquids commonly used in products that foam. They are considered water-soluble ammonia derivatives. Studies suggest that these ingredients can cause skin irritation, which can do more harm than good to your skin. Unfortunately, they are still commonly found in products like facial cleansers and soaps. 

Polyethylene Glycol (PEG) 

Polyethylene glycol is an ingredient that can affect how much moisture your skin retains. If you use too much PEG, it can dry out your skin and almost make your skin dependent on moisturizers. These are commonly labeled as PEG and are used in facial cleansers that claim to dissolve oil, grease, and debris.

DMDM Hydantoin & Urea (Imidazolidinyl) 

These preservatives can release formaldehyde into your body. This can lead to skin allergic reactions, headaches, and even joint pain. They are also known human allergens and are still used in everyday moisturizers, sunscreens, and makeup removers. 



If you're trying to avoid parabens, you’ll want to look for methyl, butyl, ethyl, and propyl on the back of the ingredient list. These preservatives can cause skin irritation and can leave your skin overly sensitive. The worst part is, parabens aren’t always labeled on skincare. They hide out in your favorite skincare products, moisturizers, and deodorants.  


If you’re someone who enjoys moisturizers with some fragrance, we have some bad news for you. These usually contain a damaging skincare ingredient called phthalates. These are commonly found in fragrance oils and are known for having the ability to penetrate your skin and enter your body.

Synthetic Fragrances 

If it's not all-natural, you don't want it. Synthetic fragrances are created from hundreds of ingredients that aren't actually labeled on the bottle. Which means you're exposing your skin and body to unfamiliar ingredients. Unfortunately, these are everywhere. They're in candles, air fresheners, perfumes, and body lotions. 


Siloxane has its pros and cons. That's why it's commonly used in a wide variety of cosmetics. The ingredient is used in shampoo because it's ideal for detangling, reducing frizz, and adding that extra shine. However, it's also a well-known toxin that can lead to endocrine disruption and fertility issues if you use it too much. This means the pros don't always outweigh the cons.


Aluminum oxide and aluminum hydroxide are common ingredients found in a wide range of cosmetics and skincare products. It’s important to note that pure aluminum is never used in skincare, only in these two compounds. 

However, this is considered to be a toxic metal. Studies show that these aluminum compounds can have estrogen-like effects on our bodies. It can also disrupt the healthy functioning of the endocrine system. Aluminum is a common ingredient found in deodorants and antiperspirants. Aluminum may cause irritation and skin sensitivity, which is why some people opt for an aluminum-free option when buying deodorant.


Sodium Lauryl Sulfate (SLS) & Sodium Laureth Sulfate (SLES) 

If you use SLS or SLE too often, it can lead to skin and eye irritation. You'll want to avoid these ingredients, especially if you have sensitive skin. They are known for being the main culprit for clogging pores and causing acne.
