It's a general comedo article but it makes some clear distictions, which i always tried to make here on this forum.
let me highlight the interesting bits:
1."A comedo can be open (blackhead) or closed by skin (whitehead), and occur with or without acne"
2."Excess keratin combined with sebum can plug the opening of the follicle.This small plug is called a microcomedo. Androgens increase sebum (oil) production. If sebum continues to build up behind plug, it can enlarge and form a visible comedo."
3."Propionibacterium acne is the infectious agent in acne. It can proliferate in sebum and cause inflamed pustules (pimples) characteristic of acne."
4."A hair that does not emerge normally can also block the pore and cause a bulge or lead to infection (causing inflammation and pus)."
my comments and questions:
many holistic approaches i made for treating acne (diet, herbs) got me relatively satisfying results BUT ONLY for inflammed comedones (acne) amd NOTHING for my whiteheads. i also notice that bp works even greater but if i don't apply twice/day, i immediately get small whiteheads. this article explains that the microcomedones were always there - all these approaches just prevents them from evolving into a more larger visible comedo (by killing propinibacterium-acne bacteria). i'm wondering if i should better search for adapalene or if you know something particularely great for whiteheads (they are my main problem).the sulful soap i don't find particularely effective. and i've not explored salicylic acid too much.
i also feel revenged by this article reference to hair not emerged causing infection, which is what was my long time hunch -> that acne on my face is caused by lack of mature beard/facial hair. but this seems to be partly the problem.
