It is harnessed through filters to provide a narrow directional beam of light. - Describe how laser light is created. Fibroblasts- Water Melanin - Pigment Oxyhemoglobin- Oxygenated blood - What are the three major chromophores in the skin and their definition? Bi- Polar are opposites of positive and negative where the current flows superficially in the path of least resistance from 1 electrode to another. Mono-Polar is alternating electrical energy that creates resistance at the epidermis and converts it to heat. - What are the differences in Bi- Polar and Mono-polar radio frequency energy? It is the removal of surface material from a body; usually associated with a wound. - Define Ablation. Selective targeting of dermal structures with light energy to avoid causing damage to surrounding tissue. - What is selective Photothermolysis? Thermal Relaxation Time - ____________ is the amount of time it takes a substance, after heating, to return to its normal temperature. For ablation to occur we have to encourage TEWL - Why is transepidermal water loss important during laser treatments? Immune cell/ Scavengers that clear debris in tissue injury. - What is a Macrophage Candela, Lumenis, Alma lasers, Cynosure, Cutera - What laser/light hair removal devices are appropriate for darker skin types? Fractional -alternates ablative and nonablative laser functions focussing on the Dermis and Epidermis only. Ablative- Resurfacing of the epidermis only - Describe the difference between fractional and ablative resurfacing.
