CurrentBody Skin LED Face Mask Series 3 and Dr. Renú SpectraLift Advanced, side by side. They share no listed wavelengths; CurrentBody Series 3 lists 750 LEDs and Dr. Renú SpectraLift lists 280. What the brand lists only; neither is ranked.
Both list red and near-infrared light, the pairing used in several wrinkle studies.
Both list blue light, which acne studies paired with red.
Sessions differ: 10 min versus 10–15 min. Session time alone does not set the dose; output matters too.
Six studies match both, including why the amount of light matters.
