Hi Matildađ
Thank you for your questionâš
To charge your Silkân LED Face Mask, do the following:
1. Connect the smaller end of the USB cable to the charging port on the mask and the larger end to a USB power adapter, such as a wall adapter or computer.
2. Let the mask charge fully before first use and when the battery level is low.
3. When the battery level is low, the indicator light will blink three times before the product automatically turns off.
4. To make the battery last longer, it is recommended to charge the mask regularly, even if it is not used often.
Also, feel free to check the user manual that comes with it.
Please reach out if you have more questions, and I hope you have a lovely dayđ
