BEAUTY SCIENCE: Non-comedogenic

In order to understand what "non-comedogenic" means, it may be helpful to break the word down. A comedo (or comedones, if more than one) is a type of pimple, or lesion that can form on your skin. Pimples differ according to their appearance and what causes them. 

A comedo, the least severe form of acne, is the result of a clogged pore. Pores are the tiny openings in your skin that you can see when you look very closely, especially in a magnifying mirror. Inside those pores are hair follicles -- sacs beneath the skin that house the hair root -- and that's where pimples begin. When your body produces excess sebum, it can combine with dead skin cells and sometimes bacteria to plug up the pore. The result is a pimple -- a comedo. If the comedo is closed at the skin's surface, it's called a whitehead. When it's open at the skin's surface, and you can see the plugged follicle darkened by melanin buildup, it's called a blackhead.

Substances that cause your pores to become clogged and develop comedos are said to be comedogenic.  Non-comedogenic products shouldn't clog your pores. Non-comedogenic is essentially “non-pore-clogging”. If you have combination, oily or sensitive skin, you should use "non-comedogenic"  makeup and creams and cleansers.  

However, there is one thing to keep in mind:  there aren't really any regulations specifying what a company has to do to call its cleansers "non-comedogenic," and products labeled that way may not work for everyone.  The next time you want to hide your inflamed and large pores with heavy foundation, stop and think a moment. Are you making the matters worse?  Your main goal is not to get a reversed effect. With no guidelines or standards in place, even the thickest, greasiest moisturizer can claim it "won’t clog pores"! As a general rule, the thicker the product, the more likely it is to be pore-clogging.  Instead, if you have oily or clog-prone skin, avoid products with a thick, creamy consistency. Look for products that have a liquid, gel, or extremely light serum texture, or a thin, water-based lotion consistency. Generally, products with thinner textures are less likely to clog pores or worsen breakouts.


  1. My skin has always been oily but in the last
    Couple of years it has become extremely Oily. I always look for noncomedogenic products but have never thought about the requirements in saying you are or you are not. Actually this isn't good to hear to me.

  2. I prefer a serum consistency rather than a lotion or cream consistency.


We love to hear from you!
