treatment regime?
Answer: Laser Hair Removal (LHR)
◉ What does the FDA call laser hair removal?
Answer: Permanent hair reduction

treatment becoming impossible called?
Answer: Patient Threshold
◉ The amount of hair per one square centimeter is known as?
Answer: Hair density
,◉ The higher the hair density, the _______ the fluence?
Answer: Lower

Answer: 30%
◉ Darker/tanned skin requires what kind of fluence?
Answer: Lower
◉ What should you never use to clean a patient's skin prior to LHR?
Answer: Alcohol

Answer: Selective photothermolysis
◉ For deeper laser penetration what should the practitioner do to
the laser?
Answer: Change to a bigger spot size
◉ The primary reason for using cooling devices during laser hair
removal is?
Answer: Allows for higher and more effective fluences to be used
while sparing the epidermis
◉ During the initial consultation, the patient should be informed
that the process will take how long for laser hair removal?
Answer: A series of treatments
