This studies was designed to investigate the importance of skin type and UV-exposure on side effects after exposure to an Intense Pulsed Light Home-use device.

21 healthy subjects will receive 8 UV-exposures on one buttock and subsequently three weekly IPL-exposures.

Primary Purpose: Basic Science

Further study details as provided by Christina Haak, Bispebjerg Hospital:

Primary Outcome Measures:
  • Changes in skin reaction development [ Time Frame: Immediately after, 1 hr after, 16-24 hrs after, 1 week and 4 weeks after IPL exposure ]
    Redness, edema, pigment changes, texture changes, blisters and crusting

Secondary Outcome Measures:
  • Pain [ Time Frame: Immediately after IPL exposure (approx. 2 min) ]

Other Outcome Measures:
  • mRNA expression of pigment markers [ Time Frame: 16-24 hrs after the first IPL exposure ]

Enrollment: 21
Study Start Date: April 2012
Study Completion Date: October 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: IPL after UV-exposure
8 UV-exposures followed by 3 weekly IPL exposures
Device: IPL-home use device
A light based home use device for hair removal

Detailed Description:
Twenty-one healthy subjects will be exposed to UV-exposures 8 times over 3 weeks on a test-area (4 x 6cm) on one buttock to induce pigmentation. This will be followed by 3 weekly IPL (intense pulsed light) exposures. At 24 hours after the first IPL exposure, biopsies will be excised from the buttocks of the subjects (4 each).The skin will be evaluated after IPL exposure for: skin reactions, pain and mRNA expression of two pigment markers. Follow-up visits is planned at 1 and 4 weeks after the third and final IPL exposure.
