High-Frequency (RF) Care: Uses thermal energy to stimulate collagen production in the deep dermal layers, helping to firm sagging skin and reduce the appearance of wrinkles.Triple High-Frequency Technology: Unlike standard RF devices, the Alto utilizes different frequency ranges (0.5MHz, 1.0MHz, and 2.0MHz) to target various depths of the skin effectively.Electroporation: Enhances the absorption of active ingredients from skincare products by creating temporary micro-channels in the skin.LED Therapy: Includes color-coded LED lights (typically Red for anti-aging/elasticity and Blue for soothing/skin texture) to address multiple skin concerns simultaneously.Microcurrent: Uses low-level electrical currents to tone facial muscles and improve skin contour.7-in-1 Functions: Targeted treatments for elasticity, pores, skin tone, hydration, and brightening within a single device.No Cartridges Needed: Unlike the DUALSONIC Professional series, the Alto is a non-consumable device (no shot-based cartridges required), making it a one-time investment for unlimited use.Ergonomic Design: A sleek, handheld form factor with an easy-to-read display for mode selection and intensity levels.
