Micro-current and red light therapy are two of the most studied non-invasive skin technologies available. Micro-current has been used in professional facial treatments for decades, it's the same technology behind NuFACE which sells for $300+. Red light stimulates collagen production at a cellular level. Combined with consistent use, most women see visible firming and lifting within 3-4 weeks. It's not magic, it's science you have to show up for.
