Threory of selective photothermolysis:
Threoy of selective photothermolysis means Laser injury confined to target chromophore such as blood vessels, Pigmented cells , an unwanted hair without injury to adjacent structures. To make this happen Must meet following criteria
Wavelength that is highly absorbed by target chromophore
Fluence- Sufficient thermal energy to damage target
Pulse duration - equal or shorter than thermal relaxation time
Spot size- big spot size for deep and small spot size for superficial targets.

Background
CO2 Laser resurfacing still considered Gold standard since 1994 for fine and coarse wrinkles , scars of various origin , open pores , uneven pigmentation etc. but some drawbacks like pain , recovery time ,long lasting erythema, risk of Hypo or Hyper pigmentation and scaring has limited its use and we started looking for new safer and effective device.

And 1540 nm lux etc. with good result
To overcome these drawbacks Erbium Laser became very popular but too little result.
Concept of Non ablative Fractional photo- thermolysis was introduced in 2003 to overcome previously mentioned side effects and improve results with Near infrared wave lengths 1550 nm Fraxel and 1540 nm lux  etc. with good result and safe but significant pain and down time and needs few treatment sessions to achieve desired result.

Medical breakthrough
Use of ablatative CO 2 Laser in Fractional mode was introduced in 2006.After nearly twenty two years CO2 Laser is back in Fractional mode. depth of tissue necrosis can be controlled with less pain ,improved result and short recovery time and new collagen production , skin tightening and hardly any  side effects. Our fractional Laser device is with new scanning algorithm that uses 180 and 300  microns beam and keeps longest possible interval between two adjacent spots in order to minimize heat accumulation around treated area This significantly reduces pain.
