Short answer: Most “not working” cases come from mismatch, inconsistent sessions, rushed technique, or starting too aggressively and needing long breaks.
If you’re frustrated, don’t jump straight to “my device is weak.” Fix the fundamentals first. Hub: At-Home Laser Hair Removal.
1) The Match Is Off (Skin Tone + Hair Color)
Confirm suitability: Skin Tone & Hair Color Guide for IPL and check quickly: IPL Suitability Checker.
2) The Schedule Is Random (Consistency Beats Intensity)
Use a real plan: IPL Hair Removal Schedule. If you miss a session, don’t panic—see: What happens if you miss an IPL session? and What if you miss a week of IPL—should you double up next time?.
3) Technique Issues (Patchy Coverage)
Fix these two rules first: Place the Window Flat During IPL Use and Move Slowly, One Area at a Time.
4) You Started Too High (Irritation → Long Breaks)
If irritation happens, restart lower and rebuild: If you take a long break, should you restart IPL at a lower level? and baseline guidance: How to Choose a Starting IPL Level.
