Heating and cooling modes

How can the device be used for eye care?

By using the hot temperature, dark circles and eye bags under the eyes can be eliminated; the cold temperature can help to eliminate fatigue and swollen areas.

After initiating the heating or cooling mode, the dual-temp head doesn’t change its temperature?

The battery level is low or exhausted. Due to the high-power consumption of the heating and cooling functions (about 15%-20% for a single use), it must be used when the power is sufficient. It is recommended to charge the device to full capacity before using the heating and cooling modes. The microprocessor encountered a brief operational error. Please connect the charging cable and place the device on the wireless charging stand to reset the device to its initial state. If the outside temperature is extremely hot or cold, it may affect the heating or cooling functions of the device. It is recommended to use the device at a suitable temperature (between 5°C and 28°C).

Why does the dual-temp head feels hot in the heating mode?

The peak temperature of the heating function is 40 degrees. After testing, this temperature is the lowest temperature that can effectively remove dark circles. Because the skin of the eye is sensitive, the sudden change to a temperature of 40 degrees will cause a stress reaction. It is recommended that the dual-temp head is placed on the skin immediately after the heating mode is turned on, and the temperature change will be more gradual.
