Cosmetics group L'Oréal has unveiled two new beauty tech developments that use light technologies for hair and skin care. A novel LED face mask, currently still in the prototype stage, is designed to reduce the signs of ageing. The "Light Straight + Multi-Styler" for hair care uses patented infrared light technology in combination with glass plates to achieve good styling results at significantly lower temperatures than conventional devices, while protecting the hair structure. According to the company, both devices are scheduled to be launched in 2027.

Red light against lines

The L'Oréal Group has unveiled a novel LED face mask. The ultra-thin, flexible silicone mask, which is currently still in the prototype stage, emits light directly onto the face. The company is convinced that the mask reduces visible signs of skin ageing such as fine lines, sagging skin and uneven complexion through red light and near-infrared light. The lightweight and flexible design is intended to integrate well into the daily skincare routine. The light is said to visibly tighten and smooth the skin while evening out skin tone. The LED mask was developed by L'Oréal in collaboration with iSmart, a global leader in LED device innovation.

Less heat than old straighteners

The Light Straight + Multi-Styler developed by L'Oréal Research & Innovation uses patented near-infrared light technology. The light influences the internal molecular structures that determine the shape and texture of the hair. The glass plates straighten the hair at a maximum temperature of 160 degrees Celsius. According to L'Oréal, the device worked three times faster in tests and made hair twice as smooth as leading premium hair straighteners. Traditional heating plates would reach temperatures of 200 degrees Celsius and above. According to L'Oréal, these temperatures exceed the threshold at which keratin decomposes. This leads to weakened hair protection barriers, hair breakage and reduced shine. According to a US survey conducted by L'Oréal in 2024, 58 per cent of women surveyed said their hair damage was caused by heat.
