ZIIP HALO uses Dual Waveform Technology™ that treats a range of skin concerns including wrinkles, sagging skin, blemishes, pigmentation and dull texture. Dual Waveform Technology™ was created by our Founder Melanie Simon in 2015 when she created the world's first at-home electrical beauty tech that fused both microcurrent waveforms and Nanocurrent™ waveforms to maximize skin results. While Nanocurrent™ locks in lasting results and boosts skin health, microcurrent provides an immediate lift and firms the face. Together, these waveforms create the perfect synergy for achieving luminous and sculpted skin. Comes with 1 bottle of Golden Gel & 1 bottle of Crystal Gel. Never opened- never used.
