I'd know; I've tried several masks over the past year that I've been testing red-light therapy masks and LED devices here at WIRED. You can find me testing some kind of red light device almost daily, from soft, flexible masks to even a red-light cap for hair growth. While I've mainly tested masks, there's another handy little gadget I've also tried: Solawave's 4-in-1 Renewal Wand.
If you're looking for a more budget-friendly option, the Angauss Therapy Rechargeable Face Mask on Amazon is great for just $45. It's rechargeable, lightweight, and even comes with built-in eye protection and adjustable straps. It uses red light, which helps support collagen repair and even out skin tone, especially with consistent use. Plus, it has seven color options, each designed to target a different skin concern for under $50!
