Pulsed Light Systemstarget the Global Anti-Aging
Market

• Systems using high energy pulses of light
  (generated by laser or flshlamp) are used in the
  field of medical wellness, the beauty /
  aesthetic area and cosmetic dermatology with
  typical application in
• Removal of unwanted hair,
• Removal of coloration changes,
• Treatment of telangiectasis,
• Treatment of acne
• Skin rejuvenation
• Large amount of clinical studies show the
  effectiveness of the method, especially in the
  removal of unwanted hair.
• Photorejuvenation currently ranks as one of the
  highest volume aesthetic procedures in the world.
  
• Today, the Intense Pulsed Light (IPL) technology,
  which uses high energy flashlamps as sources of
  light, has replaced the laser devices in many
  applications.

IPL Devices

• Analysis of the market shows, that only a few
  devices reach the current state of the art
• Main disadvantages of current devices are
• Approval as medical device missing
• Poor usability of the main system
• Change of the flashlamp too complicated
• Poor usability of the handheld applicator
• High level of pain for the patient
• High costs for the customer

Photoepilation Removal of Hairs

• High energy light pulses applied to the skin heat
  up the root of the hair (absorption of energy in
  coloured hair) the hair generating cells are
  destroyed. The optimum wavelenght of light is
  between 650 nm 1200 nm.
• High densities of energy are required 10 J/cm2
  to 45 J/cm2.
• Problem The upper layers of the skin must not be
  heated!
