Laser Skin Resurfacing: How It Works

by Ellen Lucas

Laser technology has become increasingly popular to help with aesthetic improvement. Laser technology is used to whiten teeth, provide anti-aging procedures, get rid of stretch marks, and more. One laser technology that can be helpful for anyone looking to improve their appearance is laser skin resurfacing, which can help to remove acne scars, wrinkles, dark spots, and more. Here is how the procedure works:


The first thing that is done is administering anesthesia. The amount given to the patient all depends on the type of procedure. For example, for a patient who has minor scarring they want to be rid of, they may only receive a topical anesthesia, which is simply a cream that is placed on the surface of the skin to numb it. But if a patient wants something more extensive done, then they may receive anesthesia through an IV or oral sedative. 


First, the skin is thoroughly cleaned to prevent any dirt from affecting the procedure. Once the skin is cleaned, the eyes may have a barrier placed on them in order to protect them, and finally, a special gel is applied to the face, which will help the laser device to move against it smoothly. 

Co2 Laser: 

The Co2 laser is a wand-like device that is moved around the surface of the skin. This laser works to remove the top layers of the skin that are damaged in order for the undamaged skin to surface, which is what will remove the scars and other imperfections completely. Once the surgeon has found damaged skin, the laser will emit a light, and that light is what vaporizes the top layer of skin. The patient with the help of the anesthesia used earlier. 


Once the procedure is over, the surgeon will apply a cooling agent to the skin to help reduce swelling and pain. This is helpful, since once the anesthesia stops working, the patient will begin to feel the effects of the laser resurfacing procedure. 

Protective Coating:

After the cooling agent is applied, the surgeon will apply sunscreen, as well as a healing gel and sometimes bandages if necessary. These should stay on as long as the surgeon recommends. 

Knowing how the procedure works can make anyone feel more comfortable with the process. It is helpful to know what to expect and what measures are taken to protect the skin once the process is done.
