Glossary
A clogged pore (hair follicle) plugged with a mixture of dead skin cells, sebum, and sometimes bacteria. Open comedones are blackheads; closed comedones are whiteheads. Comedones are the precursor to most forms of acne.
A comedone forms when a hair follicle (pore) becomes plugged with a combination of dead skin cells (keratin) and sebum (skin oil). If the plug remains beneath the skin's surface with a closed top, it forms a closed comedone (whitehead): a small, skin-colored or slightly raised bump. If the plug reaches the skin's surface and the pore opening remains open, it forms an open comedone (blackhead). The black color is not dirt; it is the result of melanin pigment and sebum oxidizing when exposed to air.
The root cause is excess keratin production inside the follicle, a process called follicular hyperkeratinization. Dead cells that should shed individually instead clump together and form a plug. Contributing factors include hormonal fluctuations (which increase sebum production), slow skin cell turnover, genetics, and external factors like occlusive skincare products that trap debris in the pore.
This is where the comedogenic rating of skincare ingredients becomes relevant. Ingredients with high comedogenic ratings (like cocoa butter at 4/5 or coconut oil at 4/5 on the face) are more likely to contribute to pore plugging. Ingredients rated 0-2 (like argan oil, jojoba oil, and kokum butter) are far less likely to cause comedone formation.
Regular gentle exfoliation (removing the dead cells before they can form plugs), using non-comedogenic products on the face, keeping skin clean without over-stripping natural oils, and maintaining consistent moisture (dry skin actually increases comedone formation because the body compensates by producing more sebum) are the foundational prevention strategies.
No. The black color of a blackhead comes from oxidized melanin and sebum, not dirt. Scrubbing harder will not remove blackheads and may irritate the skin. Gentle exfoliation and non-comedogenic skincare are more effective than aggressive cleaning.
Some can, if they contain comedogenic ingredients. Heavy oils and butters applied to the face can contribute to pore plugging. This is why we formulate our facial balm with low-comedogenic ingredients like argan oil and kokum butter rather than the heavier coconut oil and shea butter used in our body products.
