The Wonders of the Skin - Common Skin Dissorders - Miscellaneous

Here are some common skin dissorders. Lets talk about blackheads. Blackheads form when a hair follicle gets filled with oil and cells, but the top remains open. The top surface will darken as a result.

Now i'll tell you about whiteheads. Whiteheads form when oil and skin cells block the opening of a follicle, causing the pore to close and the follicle to get big. The skin on the top only turns a little pale.

Now I want to tell you about a pustule. A pustule is a swelling that has pus. It happens when there is a rupture (when dead cells, inflammatory cells, and bacteria build up) in the top part of a follicle. Now I'll tell you about something that has a weird name for what it is. It is called a Nodular acne, and it is a boil like thing. Nodular acnes occur when a hair follicle gets plugged with dead cells, inflammatory cells, and skin oils. It's result is a orange-yellow shaded boil.

Now I'm going to tell you about contact dermatitis. Contact dermatitis is an allergic reaction. It creates red, itchy areas around the skin that can form blisters. It is caused when a certain substance or chemical touches the skin.
