Whiteheads happen when pore completely blocked, trapping sebum(oil), bacteria and dead cells that caused a white bump on the surface. We can see it clearly especialy the time it begging to pop out.
It can be treated by apply retin A, salicylic acid, cleocin-t,sulfur or normal benzoyl peroxide caused it kind of mild acne problem. Else, you can get it clear by oral antibiotics where you can get it from your dermatalogist.
2. Blackheads
Blackheads happen when a pore is only partially blocked, allowing some of the trapped sebum (oil), bacteria, and dead skin cells to slowly drain to the surface. The black color is not caused by dirt. Rather, it is a reaction of the skin's own pigment, melanin, reacting with the oxygen in the air. It will take a long time to clear it.
Same as the whiteheads by using retin A, salicylic acid, cleocin-t, sulfur and benzoyl peroxide. Otherwise take oral antibiotics.
3. Papules
Papules are inflamed, red, tender bumps with no head.
Same as white and blackheads.
4. Pustules
A pustule is similar to a whitehead, but is inflamed, and appears as a red circle with a white or yellow center. Pustules are your garden variety zits.
Same as white and blackheads.
5. Nodules
As opposed to the lesions mentioned above, nodular acne consists of acne spots which are much larger, can be quite painful and can sometimes last for months. Nodules are large, hard bumps under the skin's surface. Scarring is common. This is so called severe acne problem.
For severe acne, the dermatalogist will high recommend to take isotretinoin or accutane which derived from Vitamin A. But before you take this medicine your derm will do some blood and pregnancy test to ensure that you are not pregnant and carry any high blood pressure problem. You can't get pregnant during treatment and need to do regular blood test in monthly basis or before subscribe the medicine.
