Why Does Comedonal Acne Appear on the Face?

If you've taken a close look in the mirror and you see that your skin looks rough and full of small flesh-colored or dark-colored bumps, especially on your chin, nose, and cheeks, you're probably dealing with comedones. And although they appear more on the face, they can also appear on the neck, chest, and back.


Why do comedones appear on the face?

Comedones are blockages of the pores (follicles) of the skin. They are a plug caused by oil accumulation, which prevents the sebaceous gland from draining. 

When oxidized, they become dark, with a blackish hue. When the sebum cannot escape, pimples appear, and if they become infected, they give rise to pustules. 

Contrary to popular belief, they are not directly related to acne, but rather to excess oil, and are more frequent in hot weather.
