Light Tissue Interaction
Reflection:
- Fraction of total energy is "wasted" due to the reflection off the epidermis.
- The reflection off the skin varies from 20% in darker skin and 60% in lighter skin.
Scattering:
- Occurs because the light beam gets "bounced" or kicked around by connective tissue as it penetrates in the skin layers.
Absorption:
- Not only dependent on laser properties in depends on the amount of color the absorbing target possesses.
- Laser light can be absorbed by the skin's epidermal surface or by the material in the tissue called a Chromophore.

- Cellular division and keratinization cesses and the follicle begin to shrink back from the papilla.
