The decision to go into the medical profession is one that hundreds of people make each year. Indeed, there is nothing more rewarding than being able to save a person's life. However, in the medical profession, there are certain branches that are actually more focused on being able to save a person's self esteem.
This is where a cosmetic dermatologist comes in. The goal of a cosmetic dermatologist is, through various technological procedures, to vastly improve the appearance of a person. Obviously, in order to have a successful medical practice, the cosmetic dermatologist will need to be well-versed in the kinds of technology that are available – specifically laser technology.
For example, if a person is having trouble with acne, a cosmetic cosmetologist who specializes in laser acne therapy will use that procedure to slowly, but surely get rid of the acne, pimple by pimple. Specifically, a pimple is caused by dirt in the skin. When that dirt ends up staying far too long in the pores, a small infection sets in.
Now, the skin is porous, but not so much so that it would allow dirt to make its way into the body. So, what the skin does is use pus as a barrier. This mini-infection becomes the actual pimple. So, in the laser treatment (which can be done in a dermatologist's office or even in some spas), the laser promotes added blood flow to the affected area, which pushes the dirt, pus, and infection, out. The result is nice and clear skin.
