Red light boosts collagen to smooth wrinkles, blue light clears acne, and near-infrared can worsen melasma by heating skin. Shereene Idriss breaks down which LED wavelengths actually work and which ones to skip.
LED light is a very difficult subject to approach in a apples to apples situation because unfortunately not all of the companies disclose the actual power, the intensity etc of the LED lights. So it's hard to know exactly what you're getting. But very, very basics. And again, sorry, my nose. Like the allergies today, I am convinced a patient came in with like 20 cats and the second she left I just could not stop sneezing. And it's still going. Anyway, so red light LED does help with boosting collagen production. Okay, yes, it does. Again, you have to do it a lot. Blue light helps with acne. Now the question is with near infrared light. I am not a fan of near infrared light, especially if you are prone to melasma because that heats it up and can trigger it ac. Absolutely it can.
