LED Esthetics Glotech Pro mask and collar is the best LED mask I’ve tried yet. As I like the Ageless Complex Serum that makes the treatment more effective & it has red, infrared and blue light all in one mask. It’s on sale but if you miss the sale use my glotech discount code glamourandgains for 10% off. Full LED mask review on my YouTube channel evedawes xoxo LTKBeauty LTKHome LTKSaleAlert
