This face brush uses RF high-frequency technology to lift and provide aesthetic effects. - Type: RF high-frequency electric brush - Accessories: Instruction manual, charging cable - Color: White - Functions: LED aesthetic treatment, RF lifting - How to use: For face and body care - Power: Rechargeable This is one of the items I ordered because I wanted to know the differences between various manufacturers. I just bought it. Even the slightest electrical current on my face was too much for me. I felt nothing on my scalp. I am trying another product from the same manufacturer. I only checked if this product turns on. Thank you for looking.
