Ulike Air 10 vs Ulike Air 3

Disclosure: Glow & Current earns a commission when you buy through links on this page, at no extra cost to you. It does not change which device wins or what we say about it — here is exactly how we are funded, and here is how we evaluate devices.

Buy the Ulike Air 10 if your hair is coarse or you want the course over with: 23.6 J/cm2 is the highest brand-stated energy density of any mainstream home handset, and ten intensity steps let you work up to it. Buy the Air 3 if your hair is fine to medium and the price gap matters - it keeps the sapphire contact cooling that makes Ulike worth buying at all, and it sits under a located clearance of its own. The upgrade is real, but it is an upgrade in sessions, not in whether the thing works.

Energy density governs how much is delivered to the follicle in a single pulse. More energy per pulse generally means fewer sessions to the same reduction, which is why the Air 10's figure is the headline specification in this category. It is also brand-stated and not independently verified, like every energy figure on every handset we checked.

What higher energy does not do is change the skin-tone ceiling or make light hair respond. Those limits are set by the mechanism, not the specification. What a joule figure tells you, and what it does not.

Wins on specification

Ulike Air 10

Ulike · Best for coarse hair and the fewest sessions

23.6 J/cm2 brand-stated, 1,000,000 flashes, 10 intensity levels and sapphire cooling held near 16-18 C. Clearances K241998 for the UI20 family and K250942 for the UI20S variants.

The highest published energy density of the mainstream home IPL handsets, paired with sapphire contact cooling.

Specifications

Energy	23.6 J/cm2, brand-stated
Flashes	1,000,000
Intensity levels	10
Cooling	Sapphire contact cooling held near 16-18 C
Clearance	K241998 (UI20), K250942 (UI20S), product code OHT

FDA clearance located

Ulike's UI20 family is covered by 510(k) K241998 (Ice Cooling IPL Hair Removal Device, cleared 13 December 2024, product code OHT - light-based over-the-counter hair removal), with the UI20S variants cleared under K250942 (11 July 2025).

What works

• Located, current clearances for the exact model family
• Highest brand-stated energy density here by a clear margin
• Contact cooling makes high energy levels tolerable, which is the whole point of high energy

What does not

• Energy density is brand-stated and not independently verified
• Like every IPL handset, it is unsuitable at the darkest end of the Fitzpatrick scale
• Larger window is awkward on the upper lip

Wins on value

Ulike Air 3

Ulike · Best for fine-to-medium hair on a budget

The same sapphire contact cooling at the cheapest price in the cooled-handset class, covered by clearance K233887. Lower energy and fewer intensity steps, and Ulike does not publish a directly comparable figure for every variant.

The previous-generation Ulike, still widely sold and much cheaper than the Air 10.

Specifications

Cooling	Sapphire contact cooling
Energy	Lower than the Air 10; Ulike does not publish a directly comparable figure for every variant
Clearance	K233887, 22 January 2024, product code OHT

FDA clearance located

Covered by the Ulike IPL clearances on file, 510(k) K233887 (22 January 2024, product code OHT), which lists the UI06, UI07, UI08 and UI20 model families.

What works

• Covered by a located clearance
• Same cooling approach as the flagship
• Routinely the cheapest cooled IPL handset

What does not

• Lower energy means more sessions for the same result
• Fewer intensity steps than the Air 10
• Published specs are less consistent across variants

Specifications from FDA 510(k) K233887, checked 13 October 2026.

The alternative philosophy

Braun Silk-expert Pro 5

Braun · Best for automatic intensity and the best sensor

K190354, up to 6 J/cm2, and a SkinPro 2.0 sensor reading skin tone 80 times a second at up to 125 flashes a minute. Lower energy by design, with the safety engineering to match.

The sensor-led handset: it reads skin tone 80 times a second and sets the intensity for you, which is a different design philosophy to maximizing energy.

Specifications

Energy	Up to 6 J/cm2, brand-stated
Flashes	400,000
Intensity levels	10, set automatically by SensoAdapt
Sensor	SkinPro 2.0 reads skin tone 80 times a second
Speed	Up to 125 flashes a minute; both legs in under 5 minutes
Clearance	K190354, 18 March 2019, product code OHT

FDA clearance located

510(k) K190354 (BRAUN Silk.expert Pro 5, cleared 18 March 2019, applicant Cyden Limited, product code OHT).

What works

• A located clearance with a named applicant and date
• The continuous skin-tone sensor is the best safety implementation in the category
• Fastest glide mode here

What does not

• 6 J/cm2 is a quarter of the Ulike figure, so expect more sessions
• Automatic intensity removes the control some users want
• Corded operation on several variants

Sapphire contact cooling is the reason Ulike handsets tolerate high settings. Cold glass against skin blunts the sting of the pulse, which sounds like comfort and is really about compliance: a setting you can bear is a setting you will use, and an unused high setting delivers nothing.

Both generations have it, and that is the strongest argument for the Air 3. You are not giving up the brand's defining feature when you buy the older model - you are giving up intensity steps and energy headroom.

• Air 10 for coarse or dense hair, for the bikini line, or if you want the shortest realistic course. The full Air 10 review.
• Air 3 for fine-to-medium leg and underarm hair where the extra energy buys you less than the price difference costs.
• Braun Pro 5 instead if you would rather the device decided the intensity. Ulike against Braun, head to head.
• Neither if your hair is light blonde, red, white or gray - no IPL handset works on it. Why.

Neither Ulike nor anyone else publishes a session-count comparison between the two, so the honest framing is directional rather than numerical: lower energy per pulse generally means working through the same follicle population over a longer run of weekly sessions. On fine leg hair that difference is small. On coarse hair it is the whole argument for the Air 10.

The schedule is the same either way - weekly during the course, then maintenance - and that schedule is where most courses fail rather than at the specification. How often you can treat, and the gaps that are not negotiable.

One more practical note: the larger window on the flagship covers legs faster but is harder to place accurately on an upper lip. If the face is a significant part of your plan, a handset with a dedicated face attachment may serve you better than either Ulike. Facial IPL covered properly.
