About :4D Full Body Shape Massager absorbs light through a Solar panel and generates a weak electrical " micro-current" that is very similar to the body's own current. Daily treatment with the roller on the surface of your skin affects skin texture, making its appearance supple, shiny and firm.
Take off the accessories such as necklace, earrings.
Piled up hair or firm them with hair band, to avoid hair entaglement, and the rolling will be more smooth. Use the hairpin for short hair.
Pay attention to the hair around the ears to avoid entanglement.
For dry or sensitive skin, please paint some lotion before usage.
