The HigherDOSE Glow Serum is formulated to plump, hydrate, and stimulate radiant skin. This innovative heat- and light-activated formula is designed to boost the benefits of the HD Red Light FaceMask. Used alone, the nourishing blend of bio-nutrients & hyper-clean ingredients is powerful on-the-go hydration. Your skin is about to glow up. How to Use: After gently cleansing skin, apply Glow Serum over face and neck and allow the bio-nutrients to absorb into the skin. If you are using without technology, continue with your skincare routine. If you are going for a supercharged Glow, secure your HD Red Light Face Mask device (sold separately) to your head and treat skin for a minimum of 10 minutes. The HD Glow Serum's light-activated ingredients will boost the benefits of this Red Light Therapy session. We recommend using your Mask and Glow Serum together 3-5 times per week. After your treatment, splash your face with icy-cold water and re-apply a few more Glow Serum drops to the face to lock in all-day radiance. 1 oz./ 30 mL
