Two people can buy the same IPL device and get completely different results. That’s not usually a faulty device. It comes down to how IPL works: it needs pigment in the hair, the right skin contrast, and steady use over weeks.
Here are the eight most common reasons results vary, and what to do about each.
Pros
- Ice-cooling for comfort
- Fast 10-minute sessions
- Visible results in weeks
- Automatic skin sensor
- Durable, well-made device
Cons
- Requires consistent weekly use
- Not a single-session fix
- May not suit very dark skin tones

1. Hair Color
IPL targets the pigment in hair. Dark brown and black hair respond best. Blond, red, grey and white hair have too little pigment, so results are weak or absent. Fix: if your hair is light, IPL probably isn’t the right tool. Consider electrolysis, which doesn’t depend on pigment.
2. Skin Tone
IPL works best with high contrast: dark hair on lighter skin. Darker skin absorbs more of the light, which raises the risk of burns and means devices block or lower the flash. Fix: check the skin tone chart. For deeper skin tones, see our guide to hair removal for dark skin.
3. Missed Sessions
Hair grows in cycles, and only growing hairs respond. Skipping sessions lets new hairs slip through. Fix: follow a schedule and set reminders. See how often to use IPL.
4. Settings Too Low
Staying on the lowest setting out of caution can slow results. Fix: after a patch check, move up to the highest setting that’s comfortable. A device with cooling, like the Ulike Air 10, makes higher settings easier to tolerate.
5. Hormones
Hormone-driven hair, such as facial hair linked to PCOS, or hair changes in pregnancy and menopause, can keep coming back. Fix: expect slower progress and more touch-ups, and talk to a doctor about the underlying cause.
6. Body Area
Legs and underarms often respond well. Facial hair and some bikini areas can be more stubborn. Fix: be patient with stubborn areas and keep up maintenance.
7. Poor Prep
Waxing or plucking between sessions removes the root IPL needs. Not shaving means surface hair absorbs the light. Fix: shave before each session and don’t wax or pluck during treatment.
8. Device Differences
Window size, energy and contact matter. A small window or poor skin contact means missed spots. Fix: overlap slightly, keep the window flat on the skin, and clean it regularly; see how to clean an IPL device.
Quick Checklist
| Problem | Likely cause | What to do |
|---|---|---|
| No change after 3 months | Light hair or skin tone mismatch | Check suitability; consider other methods |
| Patchy results | Missed spots, poor contact | Overlap flashes, clean window |
| Slow progress | Low setting, missed sessions | Increase setting carefully, stay consistent |
| Regrowth after stopping | Normal, or hormones | Touch-up sessions |
Where This Advice Comes From
These points are based on how IPL works and on manufacturers’ published instructions. This isn’t medical advice.
FAQs
Why isn’t IPL working on my hair?
The most common reasons are light hair color, missed sessions or settings that are too low.
How long should I try IPL before giving up?
Give it about three months of consistent use.
Does IPL work on PCOS facial hair?
It can help, but hormone-driven hair often returns and needs more maintenance. Speak to a doctor too.
Is regrowth after IPL normal?
Yes. IPL gives long-term reduction, not guaranteed permanent removal, so occasional touch-ups are normal.
