FAQ
Q: Long-term LED phototherapy can lead to skin photoaging?
A: Of course not! In fact, skin photoaging is mainly caused by certain bands of ultraviolet light, UV-B (290-320 nm) and UV-A (320-400 nm), which may damage the skin by promoting collagen breakdown, free radical formation, interfering with DNA breakdown and suppressing the immune system. The GYH phototherapy mask has filtered ultraviolet light and other wavelengths of light, leaving 630±5nm red light, 820±5nm near infrared light and 465±5nm blue light. These lights are not only harmless, but also have many benefits, such as improving sleep quality.
Q: Do LED masks work better the longer you use them
A: LED phototherapy belongs to the category of low-level light therapy, with biphasic dose effect. It is found in clinical treatment that the best effect is only under optimal conditions, and too high or too low light parameters will reduce the effect. The parameters mainly include wavelength, irradiance and flux. GYH has an accurate grasp of wavelength, irradiance and flux to ensure the safety of parameters. As long as you use it within the recommended time range, there will be no problem.
Q: Why combine red and infrared light therapy?
A: The function of LED red light is very powerful. There is an "optical window" in the skin tissue, and the wavelength of red light and near-infrared light is just within that range, so the light can penetrate the skin tissue to the maximum extent. So the combination of red and infrared light can penetrate deeper into the skin cells for a more dramatic healing effect.
Q: Will the cable-free design of the built-in battery have trouble with frequent charging?
A: The product contains a 1000 mAh lithium battery, which can run for 2 hours when fully charged, with an average skin care time of 15 minutes each time, can be used 8-9 times, and can be used for a long time for 60 days when not used at all. .
Q: Can phototherapy masks completely replace other skin care and anti-aging products?
A: No, in fact with the right skin care products can make the effect more significant. Phototherapy mask is a kind of beauty instrument, which can promote cell metabolism and improve the youthful state of skin cells. After phototherapy skin care, more attention should be paid to skin care processes such as hydration. Light therapy also has a biphasic effect, and the right dose can achieve a more ideal effect, so you may not use a light therapy mask every day, but you can continue to use skin care products every day.
Q: Will the light burn the skin?
A: LED cold light uses photochemical action to rebuild collagen, dilute fine lines, improve skin elasticity, promote wound repair, and reduce inflammation. It will not produce high fever, nor will it burn the skin.
Q: Is it better to have a mask with more colors?
A mask with more colors is not necessarily better than one with two evidence-based wavelengths. If you choose wavelengths that are not optimal (i.e., poor absorption), the energy will be mostly wasted. The best device to choose is one emitting evidencebased wavelengths: blue (e.g., 415 nm, 460 nm), red (e.g., 630 nm) and near-infrared (e.g., 830 nm). These wavelengths have been proven to increase ATP production in cells.
Q: Do I have to use skin care products before using a phototherapy mask?
A: You can use skin care products, but it is not necessary. Led lights will directly act on the skin to produce photochemical and photophysical reactions, and do not need other skin care products to produce effects. If you use skincare, make sure it doesn't contain sunscreen as it will block the LED light from entering your skin. If red light and near infrared light make your skin feel tight, you can apply moisturizer before using led face mask.
Q: Can men use it?
A:Yes, of course. The effect of LED mask on male and female skin is the same. And GYH Cloud-S led mask has adjustable strap & chin support, which can fit most face shapes.
