  • Ruby lasers are used for removal of tattoos as well as skin lesions.

Liquid lasers

These comprise of dye lasers utilized for treating benign skin tumors also known as vascular lesions.

The above mentioned medical lasers are but a handful. However, they are readily employed in many medical practices. The success rate of carrying out surgeries and other treatments using a laser is quite high. In addition, medical operations that were impossible before are now safe procedures. This is why lasers have become quite popular in the field of medicine.

Benefits of Laser Use

Cosmetic surgery is one medical area that laser use is extensive. It is not only safer to have a number of procedures carried out using laser technology, but it is also quite effective. Here are some benefits linked to laser use in regard to cosmetic surgery.
