Judging from the source of micro-current, nuface's micro-current needs to be charged to replenish energy, and the intensity of micro-current is relatively high, so it will have a slight current sense when used. However, before using nuface, you need to apply conductive adhesive, otherwise you will get an electric shock.

Refa's micro-current is that the solar panel of the fuselage absorbs light energy, which makes the fuselage produce micro-current, but this current is not felt by the human body.

Judging from the use effect, nuface's micro-current will focus more on electric wave skin lifting, focusing on skin lifting and compactness. Micro-current will stimulate muscles to accelerate the synthesis of collagen, which is faster than the loss of human body, so that the skin will not age ahead of time. However, nuface is not waterproof and needs to be cleaned with a wet tissue.

The use effect of refa focuses on muscle physical massage. The angle between the two rollers of refa can clamp the muscles to move back and forth. For people who lack muscle exercise, it is very convenient to use all over the body, and refa can also be used to wash your face and take a bath.
