- IAP Mode (Radio Frequency): Increases collagen production, plumps skin, improves skin laxity, reduces wrinkles, and refines facial contour.
- TS-Lifting Mode (Microcurrent): Stimulates facial muscles, lifts and tones skin, smooths fine lines and wrinkles, and helps prevent sagging.

- Cold Massage Mode: Cools and calms skin, shrinks pores, locks in moisture, minimizes puffiness, and refines skin texture.
- Warm Massage Mode: Opens pores, increases skin absorption of skincare products, and awakens skin vitality.
- Vibration Mode: Relaxes tension points, smooths lines and wrinkles, stimulates microcirculation, and enhances product absorption.
5.3 Usage Frequency and Recommendations
For optimal results, use the Nulift NL04 device regularly 3-5 times a week. You can combine modes for a comprehensive treatment.
