Dermaroller 2mm Thank you for viewing. This is a treatment tool used by rolling it over the skin. The holes created on the skin act as penetration tunnels, delivering nutrients deeper into the skin, and by creating minor injuries, it enhances skin regeneration. By using it 2-3 times a week in conjunction with serum, pores will tighten, and firmness will increase, leading to smooth, wrinkle-free beautiful skin. How to use: * Gently roll it over the skin, applying it evenly to the entire face. Be careful with the pressure, and do not press too hard. * Avoid long strokes, as this can lead to uneven pressure. Instead, roll in short strokes. * After use, disinfect with rubbing alcohol and rinse thoroughly with water. Dry in a well-ventilated place and store. * The guideline is 2-3 passes per area. Avoid rolling on the eyelids. Stored at home after one use and disinfection with alcohol. Thank you for your understanding.
