Hallo, deerabugua74,
I know two things about acne.
You know i m sure of that.
The humans, we must take a shower every day at first.
Everybody know that.
We must also wear clean underwear everyday.
Means we must change underwear everday. and we take one that come from the wash machine.
If we wear the same underwear during two days, it's dirt will attck the fragile skin. It start to itch the second day, because of this dirt.
If we don't take a shower everyday, the skin get attacked by the dirt. And pimples grow up.
Also their is something that damage our skin.
It's our fingers. Some people keep touching their face with their hanRAB.
That's bring dirt to the face. Then pimples grow up.
