The LED Series 2 is the best red light therapy mask on the market. Crafted from medical-grade silicone, it hugs your face with 236 bulbs, ensuring direct contact. It delivers three wavelengths-red (633 nanometers), near-infrared (830 nanometers), and deep near-infrared (1072 nanometers)-to target skin rejuvenation at multiple depths. I'd recommend this splurge to people who'd like to target fine lines, wrinkles, or sun damage. Reviewer Nena Farrell also noted visible improvements in her acne scarring.
