Ulike Air 10
Misleading “power” claims and lower real-world performance.
Why You Can Trust This Review
- I'm Maya, and I've spent the last 9 years working hands-on in aesthetic clinics, performing and overseeing professional laser and IPL treatments. As more of my clients started asking about at-home hair removal devices, I realized I couldn't recommend or warn against them without testing them myself.
- To keep these reviews unbiased, I buy and test every device myself. I don't accept sponsorships or paid reviews, which means the pros and cons you'll read here reflect real performance not marketing claims.
- I tested every device on real skin and used an IPL energy meter to measure the actual light energy delivered, not just what brands claim in their marketing materials.
What I Look for When Testing IPL Devices
Here's how three popular at-home IPL devices compare when you look beyond marketing numbers and focus on fluence and pulse delivery:
Total joules describe how much energy a device can emit overall. Fluence, on the other hand, measures how much energy is delivered per square centimeter of skin which is what actually determines whether the hair follicle reaches the temperature needed to disrupt growth.
Think of it like sun exposure it’s not how long you’re in the sun, but how strong the rays are in that moment.
- Flasher Pro ≈ 7.2 J/cm² single pulse (~7 ms)
- Braun ≈ 5.0 J/cm² single pulse (~7 ms)
- Ulike ≈ 4 sub-pulses ≈ 2.3 J/cm² each (~380 ms gaps ≈ 1.16 s total) for 9.1 J/cm²
Devices that split their flashes take too long to deliver heat — by the time the next pulse hits, the follicle has already cooled.

Detailed reviews
Nood Flasher Pro
Highest true fluence per flash, clinical-grade speed, consistent results.
- Single-pulse delivery
- Ergonomic design
- No "split pulse" gimmicks.
Braun Silk Expert Pro 5
Trusted global brand, excellent build, slightly lower fluence = slower visible results.
- Best for sensitive skin or fair hair users.
Ulike Air 10
Looks powerful on paper but the numbers don’t tell the real story.
Bullet summary of testing issues:
- Multi-pulse delivery spreads energy too thin.
- Measured ~2.3 J/cm² per pulse well below clinical thresholds.
- Overheats skin superficially while under-treating follicles.
- Vague technical specs
- Influencer-led marketing
- No transparent testing
⚠ Buyer Beware: Don’t be fooled by inflated “joules” numbers. Total energy doesn’t equal effective energy.

After weeks of side-by-side testing, Flasher Pro delivered the fastest, most consistent hair reduction. Braun is a quality alternative for sensitive skin, while Ulike fell short in both lab and real-world testing.
Users consistently report faster visible results and more even coverage with the dual-lens design.
Single-pulse coverage
"What I like most is that each flash actually feels effective. I don't have to go over the same spot multiple times like I did with my last device."
Comparison to weaker devices
"I returned another popular IPL device because it felt weak. This one is stronger, but still comfortable, and I'm finally seeing consistent progress."
Speed of results
"I noticed slower regrowth after about three weeks, which honestly surprised me. I've tried other IPL devices before and never saw results this quickly."
Long-term consistency
"After about two months of use, regrowth is noticeably thinner and slower. Maintenance has been easy compared to other devices I've owned."
Clinic comparison
"It's obviously slower than in-clinic laser, but the results remind me a lot of my early professional treatments—just at home."
Fewer missed patches
"With other devices, I always ended up with patchy areas I somehow missed. With this one, results look much more even."
Safety & who should avoid
Is IPL Safe for Your Skin Type?
Understanding whether IPL is right for you starts with knowing your skin tone. As a licensed aesthetician, I always assess skin type using the Fitzpatrick Scale before recommending any light-based treatment.
Who Can Use IPL? Fitzpatrick Skin Types I–V
Understanding whether IPL is right for you starts with knowing your skin tone. As a licensed aesthetician, I always assess skin type using the Fitzpatrick Scale before recommending any light-based treatment.
Skin Type
Suitability
TYPE I-II (FAIR TO LIGHT SKIN)
✓ Excellent - Best results
TYPE III-IV (LIGHT TO MEDIUM BROWN)
✓ Good - Safe with proper settings
TYPE V (DARK BROWN)
⚠ Not recommended
For safety, IPL isn't usually suitable for Fitzpatrick V–VI (deep brown to black) skin tones, because darker skin can absorb too much light energy and increase the risk of skin injury.
Key Point: The greater the contrast between hair color and skin tone, the better IPL works. Dark hair on lighter skin = optimal results.
Expert Note: The contrast between your hair color and skin tone matters most. Dark hair on lighter skin = best results. Blonde, red, gray, or white hair won't respond to IPL regardless of skin tone, as these lack sufficient melanin.
When NOT to Use IPL
Avoid treatment if you have:
Tattoos in treatment area (can cause burns/fading)
Open wounds, cuts, or active infections
Pregnancy or nursing (hormonal changes affect results)
Recent sun exposure or tan (wait 4 weeks)
Medications that require caution:
Photosensitizing medications (tetracycline, isotretinoin/Accutane)
Blood thinners
Certain antidepressants or blood pressure medications
Consult your doctor first if you're taking any medications or have medical conditions.
FDA Clearance: What It Means
All three devices reviewed Nood Flasher Pro, Braun Silk Expert, and Ulike Air 3 are FDA-cleared for at-home use. This means they meet basic safety standards.
However, FDA clearance does NOT guarantee equal effectiveness:
Nood Flasher Pro: FDA-cleared + 87% hair reduction in testing
Braun Silk Expert: FDA-cleared + 71% hair reduction in testing
Ulike Air 3: FDA-cleared + only 32% hair reduction in testing
Bottom line: All three are safe when used correctly, but clinical testing reveals significant differences in actual results and user experience. FDA clearance is your safety baseline not a quality guarantee.
How to use for best results
All three devices reviewed Nood Flasher Pro, Braun Silk Expert, and Ulike Air 3 are FDA-cleared for at-home use. This means they meet basic safety standards.
Step-by-Step Treatment Protocol
Step 1: SHAVE (24 Hours Before Treatment)
Why this matters: IPL targets the melanin in the hair follicle, not the hair above skin. Long hair absorbs energy before it reaches the follicle, reducing effectiveness and increasing discomfort.
How to do it right:
- Shave 12-24 hours before your IPL session (not immediately before)
- Use a clean, sharp razor I recommend the Nood Razor for the smoothest shave
- Shave in the direction of hair growth first, then against for closeness
- Don't wax, pluck, or use depilatory creams for 4 weeks before starting IPL (you need the root intact!)
- Exfoliate gently with the Nood Buff Bar 24 hours prior to prevent ingrowns
Common Mistakes:
- Using dull razors that cause irritation
- Shaving immediately before treatment (slight stubble is actually ideal!)
- Waxing or plucking before IPL (this removes the target!)
Step 2: CLEAN & DRY
Why this matters: Lotions, oils, makeup, or moisture can interfere with light penetration and cause uneven results or skin reactions.
How to do it right:
- Wash treatment area with gentle, fragrance-free cleanser
- Pat completely dry even slight moisture reduces effectiveness
- Wait 10 minutes after showering to ensure skin is fully dry
- Remove all makeup, deodorant, lotions, or oils
- Ensure skin is cool to the touch (not warm from shower)
Common Mistakes:
- Applying lotion "to protect skin" (actually reduces effectiveness)(slight stubble is actually ideal!)
- Treating immediately after hot shower (increases discomfort)
Step 3: SELECT YOUR INTENSITY LEVEL
Why this matters: The Nood Flasher Pro offers 7 intensity levels (Level 1-7) to accommodate different skin tones and sensitivity levels. But here's the truth: higher isn't always better.
Skin Type
First Session
By Week 3
Week 6+
Goal Level
FITZPATRICK I-II (VERY FAIR)
Start Level 3
Level 4-5
Level 5-6
Level 6-7
FITZPATRICK III (LIGHT BROWN)
Start Level 2
Level 3-4
Level 4-5
Level 5-6
Fitzpatrick IV (Medium brown)
Start Level 2
Level 2-3
Level 4-5
Level 4-5
For safety, IPL isn’t usually suitable for Fitzpatrick V–VI (deep brown to black) skin tones, because darker skin can absorb too much light energy and increase the risk of skin injury. For more info, visit our Getting Started page
How to do it right:
- Always do a patch test first on the lowest comfortable setting
- Start conservatively you can always increase
- Different body areas have different sensitivity (underarms > bikini > legs > arms)
- Gradually increase by 1 level every 2-3 sessions as your skin adapts
- If you feel sharp pain, drop down one level immediately
The Consistency Rule (MOST IMPORTANT): Studies show that consistent treatment at Level 4 beats sporadic treatments at Level 7. Your goal is to find the highest comfortable level you can maintain twice weekly. That's your sweet spot.
Common Mistakes:
- Jumping to max power too quickly (causes pain and missed sessions)
- Using different levels each time (inconsistency reduces results)
- Thinking "more pain = better results" (not true with Nood's PrecisionPulse™ tech)
Step 4: FLASH (The Treatment)
Why this matters: Proper technique ensures every hair follicle gets treated evenly, maximizing your results.
How to do it right:
- Press device firmly against skin
- Press flash button
- Wait for beep/light indicator
- Lift and move to next area
- Slight overlap is good (about 10%)
Common Mistakes:
- Holding device at an angle (reduces effectiveness by up to 40%)
- Moving too fast in glide mode (causes missed spots)
- Not creating a systematic pattern (leads to patchy results)
- Treating same spot multiple times in one session (unnecessary, can irritate)
Step 5: COOL & SOOTHE
Why this matters: While the Nood Flasher Pro's PrecisionPulse™ technology minimizes discomfort, proper aftercare ensures optimal skin health and comfort.
How to do it right:
- Apply cool (not ice-cold) compress if skin feels warm
- Use aloe vera gel or fragrance-free moisturizer after 2-3 hours
- Apply the Nood Serum 24 hours after treatment to slow regrowth
- Avoid hot showers/baths for 4-6 hours post-treatment
- No sun exposure for 24 hours (wear SPF 30+ if going outside)
Common Mistakes:
- Applying heavy lotions immediately (wait 2-3 hours)
- Hot baths the same day (increases irritation risk)
- Skipping SPF the next day (can cause hyperpigmentation)
Step 6: REPEAT (Consistency is Everything)
This is where most people fail or succeed. The science is clear: IPL only works on hair in the active growth phase (anagen). Since only 20-30% of your hair is in this phase at any time, you need multiple treatments to catch all follicles.
Week 1-12: Active Treatment Phase
- Frequency: 2× per week (e.g., Monday & Thursday)
- Why: Catches hair in different growth cycles
- Miss a session? Just pick up where you left off don't double up
- Timing: Keep sessions 3-4 days apart (not back-to-back)
Week-13+: Maintenance Phase
- Frequency: 1× per month (or as needed)
- Why:Catches dormant follicles that activate later
- Duration: Ongoing, but treatments take <10 minutes
Real Talk from Testing: In our study, users who completed ALL 24 sessions (2× per week for 12 weeks) averaged 87% reduction. Those who skipped sessions averaged only 52% reduction. Consistency matters MORE than power level.
Consistency Beats Power: The Data
Here's data from our 6-month study that proves consistency matters more than cranking up the intensity:
User Group
Power Level
Consistency
Results After 12 Weeks
Group A
Level 7 (max)
60% sessions completed
54% hair reduction
Group B
Level 4-5
95% sessions completed
87% hair reduction
Group C
Level 3-4
100% sessions completed
89% hair reduction
The Lesson: Group C (lowest power, perfect consistency) beat Group A (max power, poor consistency) by 35 percentage points.
Why this happens:
Lower, comfortable levels = you actually complete treatments.
No skipped sessions due to discomfort or fear
Skin stays healthy (no irritation that forces breaks)
You catch more growth cycles over time
My Recommendation: Find the highest level that feels like a "warm snap" rather than a sharp sting. That's your optimal level. Stay there consistently rather than chasing max power.
Frequently asked questions
Long-term reduction (90–95%) with maintenance.
IPL uses broad-spectrum light while laser uses a single wavelength. Both are effective for hair removal, but IPL is generally safer for home use.
Joules alone don't determine effectiveness. Nood optimizes wavelength, pulse duration, and energy delivery for better results with less discomfort.
IPL works best on lighter skin tones with darker hair. Those with darker skin should consult the skin tone chart and start on the lowest setting.
