Air 10 vs Air 4 vs Air 3: Feature-by-Feature Breakdown The main differences between the Air 10, Air 4, and Air 3 appear in the light system, treatment window, cooling design, and power output. The Air 10, Air 4, and Air 3 share the same underlying IPL technology, yet each device emphasises a slightly different aspect of home hair removal. Some prioritise treatment speed. Others focus on simplicity or balanced performance. The sections below examine those differences in more detail. IPL Technology Compared All three devices rely on Intense Pulsed Light technology, which delivers controlled flashes of light into the hair follicle.  The Air 10 introduces a dual-light system. Two light sources operate within the treatment head and deliver higher combined energy during each flash. This design improves coverage efficiency across larger treatment areas. The Air 4 and Air 3 use a single-light IPL system. This configuration remains widely used across home IPL devices and supports gradual hair reduction when treatments follow a regular schedule. The difference lies mainly in treatment efficiency rather than the underlying technology. Treatment Window Size Compared The treatment window determines how much skin each flash covers. The Air 10 features the largest treatment window in this comparison. The wider surface area allows each flash to treat more skin at once, which shortens full-body sessions. The Air 4 uses a mid-sized treatment window that balances speed with control. The Air 3 has a slightly smaller window, which offers greater precision when working around smaller areas such as the upper lip or underarms. A larger window generally reduces the number of flashes required during a full routine. Energy Output Compared Energy output determines how much light energy reaches the hair follicle during treatment. The Air 10 delivers the highest energy levels among the three devices. Higher output helps target thicker hair that appears in areas such as the bikini line or underarms. The Air 4 operates at balanced energy levels suited to most common treatment areas. The Air 3 uses moderate energy settings designed for gradual reduction rather than maximum intensity. Cooling Systems Compared IPL treatments generate heat as light energy converts inside the follicle. Cooling systems help maintain skin comfort during this process. The Air 10 and Air 4 use sapphire cooling technology within the treatment head. The sapphire surface absorbs and disperses heat while light pulses travel into the follicle. This design keeps the skin contact area noticeably cooler during treatment. The Air 3 includes a cooling system as well, though the design is simpler than the sapphire-based system used in the newer models. Cooling becomes particularly helpful when treating sensitive zones such as the bikini line or underarms. Treatment Modes Compared Control settings shape how easily users adapt the device to different areas of the body. The Air 10 offers multiple treatment modes, including specialised settings designed for coarse hair. The Air 4 includes adjustable energy levels, which allow users to increase or reduce intensity depending on comfort. The Air 3 keeps the interface straightforward, with fewer settings and a simple operating structure. Each approach serves a different type of routine. Advanced users may prefer additional modes, while beginners often value simplicity. Device Design and Handling Compared Design affects how comfortable the device feels during longer treatment sessions. The Air 10 uses a larger treatment head, which supports faster coverage across legs and arms. The Air 4 maintains a compact shape, which helps with manoeuvring around curved areas such as knees. The Air 3 keeps the design minimal and lightweight, making it easy to handle during shorter sessions. Comfort during handling often becomes noticeable during full-body routines. Key Differences Between Air 10, Air 4, and Air 3 The three devices follow the same IPL principle but emphasise different priorities. Air 10 focuses on speed, higher energy output, and upgraded hardware. Air 4 delivers balanced performance with strong cooling comfort. Air 3 provides a simpler approach suited to first-time IPL users. Each device supports gradual hair reduction through repeated treatments. The main difference lies in how quickly and comfortably those sessions take place. Frequently Asked Questions About Ulike IPL Devices What is the main difference between the Ulike Air 10, Air 4, and Air 3? The biggest differences are IPL technology and cooling.
