This 4 in 1 AMIRO HydraGlow Booster kit has red light, microcurrent, and a PDRN serum that actually makes my skin look tighter and more hydrated after just a few uses. I try a lot of gadgets and honestly, this is one of the most effective devices I’ve tried in a long time. You can literally see it working. PDRN serum is excellent. It comes from salmon (yep, the salmon sperm you keep hearing about), but this one has a professional level concentration of 3500 ppm. It’s very effective and gentle on sensitive skin. The PDRN is incredible for its ability to repair the skin and its anti-aging properties. Use code ASH50 for additional $50 off LTKHome LTKBeauty LTKGiftGuide
