What is the Fractional?
Dividing Laser beam very finely (smaller than hair) and irradiating to Epidermis fractionally makes many small thermal lesions to the skin structure without any serious damages. By this system, the skin will be recovered rapidly with no side effects and during this time the skin rejuvenated naturally.
Higher Water Absorption
Fractional CO2 Laser has higher water absorption, so that skin surface vaporizes and creates a Micro Ablative Columns. When you emit Fractional CO2 Laser to skin surface, the water is heated to a boiling point causing the water molecules to convert to vapor(ablation).
The heat generated creates a coagulation zone which initiates the wound healing response. As soon as skin is ablated, necrotic walinduces immediate collagen shrinkage.
The heat generated denatures the collagen which recoils back to normal collagen causing the skin to contract improving skin laxity.
