As far as I know, when the skin is very oily, it gets clogged with dirt, and acne is when pus collects under the skin. I know this because I had a lot of acne during puberty. I only got rid of them when I started taking one good medicine https://www.tadalafilaus.com/accutane.php.
Blackheads, or comedones are lesions on the skin that are open, and the top appears black. However, they are not infectious the way that pimples are. Pimples are called whiteheads, the follicle is closed, can be inflamed, and they are often filled with pus. This situation is why it is so important to wash your face regularly. It keeps skin clean, healthy, and blackhead and pimple free.
Many people believe that blackheads and pimples are mostly an issue for teenagers, but this is far from the case. There is something called adult acne, that affects men and women alike. Another essential factor with skin, which is often overlooked, is that you have to drink plenty of water and eat right to assist in good skincare.
Blackheads, which are seen in oily areas of the skin (what is known at the T zone), are pores that remain open, which makes it change color when it is exposed to air. Pimples, on the other hand, may occur in bumps or blemishes. They eventually burst and spread to the surrounding tissue.
