Red light therapy is getting more and more popular, but not all devices live up to their promises. The truth is, many masks don’t meet the standards needed to be effective and some may even do more harm than good. To help you make an informed choice, we’ve put together a short guide with the most important facts.
Red light therapy is getting more and more popular, but not all devices live up to their promises. The truth is, many masks don’t meet the standards needed to be effective and some may even do more harm than good. To help you make an informed choice, we’ve put together a short guide with the most important facts.
A red light mask should use wavelengths in the scientifically proven range of 633–660 nm, which can stimulate collagen production and help reduce redness and fine lines. [1] Near-infrared light (830–850 nm) can penetrate deeper, supporting circulation, tissue repair, and cellular regeneration. Blue light (around 415 nm), on the other hand, can be effective for acne treatment by targeting acne-causing bacteria. [2,3] However, because it’s close to the UV spectrum, masks using blue light must be properly filtered and come from reputable manufacturers to ensure safety.
A high-quality mask should have at least 100 LEDs for even light distribution and a power density of 25–40 mW/cm² to ensure real results. [4] Look for masks made from medical-grade silicone, as lower-quality materials can release harmful substances when in contact with your skin. Don’t forget the fit, as it is an essential part for good results: the mask should sit comfortably on your face and have LEDs placed near key treatment areas like around the eyes and mouth – not all masks do. And when it comes to safety claims, don’t be fooled by vague marketing. FDA-registered doesn’t really mean much. Instead, look for FDA-cleared devices and check the clearance status using the device’s name or 510(k) number. [5]
Red light therapy works best with consistent use. Ideally daily or at least five times a week for 10 to 20 minutes. [6] Patience is key, as noticeable improvements usually take six weeks or more to appear. Remember, it’s not a miracle cure, but when combined with sunscreen and trusted skincare ingredients like retinol, red light therapy can be a powerful addition to your skincare routine.
