Pulse Duration: Timing the laser's Impact

Explanation:

  • Pulse duration refers to the length of time the laser emits light during a single pulse. Shorter pulse durations are better for treating fine, thin hair, while longer pulse durations are more effective for thicker, coarser hair​(Motus AY User Manual '22).

Why and How to Change:

  • For fine or thin hair, use a shorter pulse duration to focus energy on the small hair follicles.

  • For thicker hair or darker skin, a longer pulse duration is preferred because it allows time for the skin to cool between pulses and avoids overheating the skin.

  • How to change: Set the pulse duration on the machine according to the hair thickness. The Motus AY machine allows for adjustable pulse durations from 2 to 50 ms for Alexandrite and 0.2 to 50 ms for Nd

Flashcards

  • The time the laser pulse is applied to the skin, measured in milliseconds (ms).

  • Fine hair absorbs heat more quickly, so shorter pulses are more effective.

  • For thick or deep hair, as it requires more time to heat the follicle effectively.

  • It may not deliver enough heat to destroy the deeper hair follicle.
