What is Comedogenic? And How Does it Effect Your Skin?

Comedogenic – pronounced most commonly ( ko-mead-do-jen-ick ) or alternately ( ko-mE-dE-o-jen-ick ).

bb-whatiscomdeogenicTending to clog pores especially by the formation of  acne. Any ingredient that will actually “cause” acne is called a Comedogenic

comedo is a clogged hair follicle (pore) in the skin. Keratin (skin debris) combines with oil to block the follicle. A comedo can be open (blackhead) or closed by skin (whitehead), and occur with or without acne. Your skin will appear rough, uneven and with larger-looking pores than usual.

Comedogenics have a higher tendency to produce or aggravate acne and blackheads, whereas non-comedogenic oils are less likely to produce such issues. The rating scale goes from zero to five, with a rating of zero won’t clog pores, and oils with a rating of five are highly likely to clog pores. These are what the numbers mean. 

0 – Will Not Clog Pores

1 – Low probability

2 – Moderately Low

3 – Moderate

4 – Fairly High

5 – High probability it will clog pores 

The ingredients most likely to clog pores include various oils, fragrances and number dyes.

Can you always find these ratings? No. They aren’t always provided by the manufacturer.

Product residues can accumulate inside pores, and this attracts more dirt, grime, and oil. These could become blackheads or could even result in pimples and acne. Residue inside pores will also make pores appear larger since this gets stuck and clog pores.

Here’s a small list of some of the most common skincare oils and their comedogenic ratings.

Skincare products that claim to not clog pores may be labeled noncomedogenic or non-acnegenic.

There are some exceptions to this scale if you have very tough non – reactive skin.  There are those who can put on almost anything on their skin without incident. However it can be deceiving since it’s likely you won’t develop comedones overnight  although some do.

The Toronto Cosmetic Clinic website explains that acne caused by comedogenic products may take several weeks or months to develop and can persist as long as the pore-clogging product is used.

Since wearing makeup for long periods of time can increase the likelihood of clogged pores. Be sure to remove your makeup before going to bed.
