No, you don't need to wear additional protective goggles when using the device. The device has a skin contact sensor and an integrated safety system that only emits light pulses when it is fully in contact with the skin. Avoid using it near the eyes and work in a well-lit room.
The difference between Philips Lumea 9900 BRI977/00 and BRI951/01 lies mainly in the colour of the device. Both models have the same functions such as five intensity levels, SmartSkin sensor for skin tone detection, cordless battery operation and intelligent attachments for different body areas. Technically and functionally they are identical, only the colour scheme differs.
The device can be used in the genital area, but not directly around the anus. It is intended for use in the bikini area and other areas of the body, but according to the manufacturer's instructions, use in the anus and vagina is not permitted. The skin in these areas is too sensitive and there is a risk of skin irritation or injury. The device is suitable for the bikini line and other intimate areas if the instructions for use are followed exactly.
When using the Philips Lumea IPL Series 9900, there is no need to apply gel, as is often the case with professional cosmetic treatments. The device is designed so that it can be applied directly to the skin without the need for additional gels or creams.
However, after the treatment, the application of a moisturising cream or aloe vera ointment may be recommended to soothe the skin and minimise redness. However, this is not mandatory, but rather a recommended post-treatment skin care measure.
Basically, both models offer advanced functions. Both devices can be used with or without a cable and are suitable for most skin tones and hair types, but not for very dark skin or very light-coloured hair. The IPL hair removal devices work on naturally dark blonde, brown and black hair as well as light to dark brown skin tones (I-V). Both models offer five customisable light settings and up to four attachments (depending on model) to treat different areas of the body, including the face. The SmartSkin Sensor (SenseIQ) recognises the skin tone and helps to select the most comfortable setting. The free Lumea IPL app also provides step-by-step instructions and helps to create an optimal treatment plan. The Philips Lumea 9900 is the latest model and also offers SkinAI technology with app integration, which analyses the skin and tracks the progress of hair reduction. According to the manufacturer, the Lumea 9000's high-power lamp has more light pulses and therefore a longer lifespan. However, the actual lifespan depends on the frequency of use. In general, both models offer a high number of light pulses, which is normally sufficient for many years of use.
