Skin laser surgery

There are over a thousand entities in dermatology; it is difficult to understand all in just a few pages. We are going to describe a few common skin problems. This is purely educational; if you have a skin disease, please consult your dermatologist.

The common skin lasers used in dermatologic surgery include

1) Ablative lasers such as Carbon dioxide laser and Erb:Yag laser. They are largely used for removal of skin tissues such as mole.

2) Pigment removal lasers such as Q-switched lasers and Intense Pulsed Light

3) Vascular lasers such as Pulsed Dye Laser and IPL

4) Non-ablative infra-red laser to stimulate collagen production such as 1540nm Aramis

Fractional lasers such as Fraxel. Personally, I think these lasers deliver only modest results and are prone to develop post-inflammatory hyperpigmentation.
