Acne Vulgaris
        
Acne Vulgaris or acne is a typical human skin disease which occurs normally during adolescence and may continue into adulthood. Acne Vulgaris can be identify by having "seborrhea" (scaly red skin), "comedones" (whiteheads and blackheads), "papules" (pinheads), "pustules" (pimples), "noldules" (large papules), and scarring.

Whiteheads are caused when a pore is being fully blocked by sebum (oil), dead skin cells, bacteria which cause a bumpy white appearance on the surface. Whiteheads usually has a shorter lifespan than blackheads. Blackheads Pores that are partially blocked by sebum, dead skin cell and bacteria are the cause of Blackheads, Skin's pigment exposure to air causes it to have black appearance. ("Types of Acne" A, [n.d.] ) Papules are inflamed red bumps with no head, squeezing papules causes scar. Pustules are red circles with yellow or white center. They are also known as pimples and are very common among people going through puberty due to the increase in hormones. Nodules are more severe than seborrhea, comedones, papules, pustules and noldules. It can permanently damage the skin. Nodules usually are big hard bumps under the skin and can be painful, they can last for months. Squeezing nodules is dangerous according to dermatologists.
