Other Tests

See the list below:

  • Do not forego skin patch testing, the most important step in laser hair removal. The results of skin patch testing determine the settings for the laser and the safety profile.

  • Perform testing in a low-visibility area with the same skin type as the area intended for treatment. If possible, allow at least 3 days before reexamining the site to assess for efficacy and for a reaction.

  • If sufficient energy is delivered and absorbed, a generalized hyperemia reaction with mild focal swelling is visible after 3-5 minutes.

    • Increase the fluence for the particular skin type, and note the patient's pain reaction until the hyperemia reaction is observed.

    • For light or thin hair, the reaction may be minimal even at high settings.

  • Note the laser setting for each type of treated area.
