Comedogenic Ingredients • Official Skin Nutritious List

Would it surprise you to know that a huge percentage of skincare and makeup products can actually cause acne? There are over 120+ comedogenic ingredients scientifically shown to trigger product acne (a.k.a. acne cosmetica). 

Take a look here at the difference between product acne (from comedogenic ingredients) and hormonal acne: 

 

Comedogenic ingredients will only cause tiny little white bumps on the skin. They do not cause deeper, painful hormonal acne (i.e. red, cystic, inflamed). It's important to know which kind of acne you have so you know how to resolve it.

Product acne is such a common problem in my clinic that approximately 80% of new clients I see are using comedogenic products without knowing it. I cannot stress enough the importance to always check every product you use for comedogenic ingredients. Even a single comedogenic ingredient or one-time use cloggy product (i.e. a mask or a friend's sunscreen) can trigger these little breakouts if you're susceptible to them. Be vigilant about avoiding these to keep your skin clear!

This list is comprised of 100% scientific research. All the ingredients listed here are from the only scientific study we have on comedogenic ingredients, "Comedogenicity and irritancy of commonly used ingredients in skincare products. Society of Cosmetic Chemists, 1989." Bless Doctor Fulton for his pioneering work in the acne field!

You may find other online sites with different "comedogenic" ingredients, but the sourcing of the information is unknown and not supplied (if you find one with sources and footnotes on research, please send it to me to check out!). Instead of making speculations, I have stuck with the straight science. And in my 9 years of client work, this list is extremely reliable and trustworthy. important notes:

Natural skincare can (and often does) contain comedogenic ingredients. Natural skincare is not immune from pore-clogging ingredients. In fact, most natural products have not been made with acne-prone skin in mind and can contain some of the most comedogenic ingredients tested such as coconut oil, almond oil, soybean oil, avocado oil, olive oil, and more. Check the list to make sure your products are comedogenic-free. 

Not everyone breaks out from comedogenic ingredients. People who are not acne-sensitive, have naturally dry skin, and small pores may not be affected at all by comedogenic ingredients. Sensitivity varies, which is why some people do not breakout from these ingredients and some do. Acne-prone skintypes are typically highly sensitive, which may be in part due to their naturally larger pore size.

Beware of untested carrier oils. Most carrier oils used today were not tested in this 1989 study such as argan oil, borage oil, hemp oil, macadamia oil, pumpkin seed oil, rosehip oil, tamanu oil, walnut oil. These cannot be confirmed as acne-safe and most oils that were tested came up as comedogenic. I strongly recommend to avoid them. 

Sunflower, safflower, jojoba, and all essential oils are acne-safe. While most oils are comedogenic, jojoba, safflower, sunflower, and all essential oils were all found to be acne-safe. Feel free to use these ingredients without worry.

Shop Skin Nutritious for non-comedogenic, acne-safe skincare. I created my skincare line because I found it very difficult to find acne-fighting products that were also non-toxic. If you want clear skin results in the most natural way possible, these products were 100% made for you.
