Laser Assisted Lipolysis - Hong Kong

Clinic Science

1 Skin-Heat Interaction

When a reversible thermal injury is created in control situation, the body’s response is to release mediators responsible for the healing process.

In turn, fibroblasts are stimulated to generate and lay a bed of newly formed collagen.

As more and more collagen is produced, the skin thickens and becomes more pliable leading to skin contraction.

2 Fat-Heat Interaction

At temperature below 45℃, any damage done to fat cells is fully reversible and sustained modifications will not be achieved.

Between 45℃ to 65℃, the cell membrane –though not ruptured- is permanently damaged and will gradually be absorbed by the body through macrophage activity.

Heating temperature over 65℃ will rapture cell membranes, allowing for removal via suction or gradual endogenous re -absorption.

3 Volumetric Heating

To effectively treat this fat area, the tissue absorption needs to be low enough to have an in-depth effect within the desired target.

However, it is equally important to ensure the absorption isn’t too low, ultimately requiring excessive power levels to raise the tissue temperature.

This requirement of “ little, but enough absorption” accurately describes 980nm.

1064nm laser is poorly absorbed in fat, and can therefore affect large volumes with minimal selectivity posing risk to surrounding structures.

In contrast, 1320, 1440 and 1470nm are highly absorbed in fat, affecting only a small volume of tissue at any given time.

This results in very high temperature over small volumes creating hot spots in adipose tissue.

Water, as with CO2 and other skin rejuvenation lasers, is the main target in the case of skin tightening with laser lipolysis.

Water has a moderately high absorption peak at 980nm.

The preferred 980nm has a greater potential for skin tightening without the increased risk of severe superficial thermal damage.

With its highest absorption in water and haemoglobin blood vessels coagulate immediately which results in less bleeding, swelling and bruising.
