Short answer: Most people treat underarms once per week for 6–8 weeks, then switch to maintenance every 2–4 weeks based on regrowth and skin comfort.
Recommended underarm IPL schedule
Tip: If hair is still coming back fast at Week 8, stay weekly for 2–4 more sessions before switching.
How to do underarm sessions correctly
- Shave first: Shave the Area Before Using MITHLUX.
- Keep the window fully flush: Place the Window Flat During IPL Use.

If you miss a session, what should you do?
