Answer:After facial cleansing and patting toner gently onto your skin, you may start your eye care with the device. Select the working mode according to your personal needs. After use, apply eye cream to boost the absorption of skincare products, leaving your skin plump and translucent. Use it every other day, and discontinue use during menstruation.

Answer:Please power off the device immediately after use, then store it in a well-ventilated and dry place. Do not place heavy objects on top of it. When cleaning, make sure the power is turned off. Wipe the surface with a damp paper towel. Do not clean it with alcohol, and never submerge the unit in water for washing.

Answer:Based on clinical observations, due to individual physical differences, a small number of users will experience a treatment cycle where stretch marks first spread out and then gradually fade. Therefore, widening of stretch marks is a normal reaction, and there is no need for excessive concern.

Answer:It is learned that this research outcome revises the long-standing conventional belief in the global medical community that "red light exerts no influence on sleep-wake behaviors of nocturnal animals such as mice". It provides theoretical support for precisely configuring nighttime illumination parameters in experiments on nocturnal animals and obtaining more reliable medical experimental data. Meanwhile, the research bears important guiding significance for the development and application of household healthy nighttime light sources. The study has been published online in Light: Science & Applications, an authoritative international journal under Nature Portfolio, attracting widespread global attention. The renowned international optoelectronic journal Light World also featured this achievement as a key report. It is reported that mice, a common research subject in life science experiments, share the habit of nocturnal activity and diurnal rest with other nocturnal animals. Their activity level drops rapidly and they fall asleep quickly upon exposure to white light. For a long time, the global medical circle held that mice lack red color vision, so red light was widely adopted for nighttime illumination. Researchers believed "red light does not disturb the sleep-wake behaviors of nocturnal animals like mice", thus avoiding interference of nighttime lighting on their sleep and other behaviors.
