Features

Skin Tone Detection Function

The device features a skin contact sensor that enhances safety by preventing accidental use. This function helps to ensure that the device is only activated when in contact with the skin, reducing the risk of unintended flashes and potential eye exposure. It contributes to a safer hair removal experience.

Attachment Head Function

This device does not come with interchangeable attachment heads for different body areas. The single, standard head is designed for versatile use, but lacks specialized attachments for more precise treatment on sensitive areas like the face or smaller, curved areas. This may limit its effectiveness in certain regions.

Cooling Function

The device incorporates a skin cooling solution to minimize discomfort during treatment. This cooling function helps to alleviate heat and pain, reducing skin irritation and enhancing the overall user experience. It allows for a more comfortable hair removal process, especially on sensitive areas or at higher energy levels.

Continuous Irradiation Function

The device offers a continuous flash feature (Auto Mode) that enables quick and efficient treatment of large areas like legs and arms. This function eliminates the need for constant clicking, allowing for a smoother and faster hair removal process. It significantly reduces treatment time and effort.

Irradiation Level Adjustment Function

The device features 6 adjustable energy levels that can be tailored to your skin's unique requirements. This allows users to customize the intensity based on their sensitivity, starting with a low level and gradually increasing as needed for comfortable and effective treatment. It ensures a personalized hair removal experience.

Safety Sensor Function

The skin contact sensor acts as a safety sensor, preventing light irradiation unless the device is in full contact with the skin. This function prevents accidental light exposure to the eyes and unintended irradiation, making hair removal safer and more controlled. It ensures that the device only emits light when properly positioned.

Ranked #37 out of 100 products in Category
3.8
Overall Rating

This device offers a diode laser for home use, potentially more effective than IPL but less so than professional treatments. It's positioned as a mid-range option with limited long-term durability data.

IPL (Intense Pulsed Light) Technology
3.5
While this device uses diode laser technology, understanding the principles of light-based hair removal is crucial. Diode lasers target melanin in hair follicles, but effectiveness varies based on energy levels and wavelengths. Adjustable settings are important for matching skin tone and sensitivity.
Skin Tone and Hair Color Compatibility
3.8
This device is designed for skin tones 1-5, making it unsuitable for very dark skin. The contrast between skin and hair is essential for effective targeting. It may be less effective on blonde, red, gray, or white hair due to lower melanin content. Always check compatibility before use.
Treatment Area Size and Speed
4.0
The device features a 30*10mm nozzle and a rapid flash rate of up to 100 flashes per minute, allowing for relatively fast treatment times. The continuous flash feature (Auto Mode) enhances efficiency, especially for larger areas like legs and arms. This optimizes treatment time and convenience.
Safety Features
4.2
Equipped with a skin contact sensor to prevent accidental use and a cooling solution for a painless treatment experience. These features enhance safety and comfort during use. Always follow the manufacturer's instructions and perform a patch test before your first full treatment.
Ease of Use and Ergonomics
4.3
The device offers one-touch operation and 6 adjustable energy levels, making it relatively user-friendly. No goggles, creams, or gels are required, simplifying the process. A clear display and intuitive controls enhance the overall user experience, even for beginners.
Number of Flashes and Lamp Lifespan
3.8
The estimated number of flashes for this device is unknown, which impacts its long-term value. A higher number of flashes ensures more treatments and a longer lifespan. Consider this factor when evaluating the overall cost of ownership and comparing it to other devices.
Manufacturer Reliability and Warranty
2.5
Manufactured by Wuhan Lotuxs Technology Co., Ltd., an emerging company. While it offers a one-year warranty and a 90-day money-back guarantee, assess the manufacturer's reputation and read reviews to gauge reliability and customer support quality.
Cost Performance
4.0
Priced at $399, this device offers a balance between features and cost. Consider the long-term savings from avoiding salon visits, but also factor in the unknown lamp lifespan and manufacturer reliability. Compare the cost per flash to other devices for better value assessment.

Q.Is this device safe to use at home?

A staff member mentioned some hair that IPL could not remove started to fade with this device.
Q.What is the size of the treatment window?
A.The device features a 30*10mm treatment area. Some staff have noted that this is a small treatment window, potentially making it more suitable for facial and underarm areas.
