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.
If you want to be on the safe side, choosing professional treatments like those we offer at AYUN is the smartest choice. With the right wavelengths, optimal power and expert guidance, we help you achieve your desired results.

You are 44 years old. Sharp, organised, high-functioning. But lately you cannot find the word you are looking for mid-sentence. You wake at 3am and lie there for an hour. You are eating the same way you always have, but your waist is changing. Your hair is coming out in the shower. You feel like yourself but not quite yourself. Your GP ran blood work and said everything looks normal.What you may be experiencing are the early signs of perimenopause and they are some of the most commonly searched and least explained symptoms in women’s health. Brain fog, hormonal hair loss, night sweats, weight gain that does not respond to diet: these are not random. They are biological signals, each one pointing to a specific process that is shifting in your body. Understanding what is behind each symptom changes everything about what you can do about it.

You eat well, stay active, and still your body begins to change. Your cycle becomes irregular, your period may disappear, or your weight increases despite doing everything “right.” Many women experience this combination without a clear explanation for a long time. Often, the cause is not lifestyle alone, but a deeper hormonal imbalance, such as PCOS.

You eat well, exercise regularly, and still your body seems to be changing in ways that are hard to explain. The scale barely moves or even goes up, despite your efforts. At the same time, your cycle becomes irregular or your period stops altogether. Many women first assume stress or diet is to blame. But often, there is an underlying hormonal cause, such as PCOS.
