Q:What is Phototherapy/Light therapyHow does it work
A:Phototherapy, also known as "light therapy," uses low-level light therapy (LLLT) to stimulate photochemical reactions in the skin. By using the correct wavelength and irradiance, the LED light source can generate photons of light energy that are absorbed by chromophores in skin tissue, leading to improved cell metabolism and healthy cell proliferation.
The GYH LED Light Therapy Mask is specifically designed to provide the skin with the optimal wavelength, irradiance, and low-intensity LED light dose, helping to activate keratinocytes and restore firmness to aging skin. GYH LED light can also activate fibroblasts in the skin, promoting the production of collagen and hyaluronic acid, which deeply moisturizes the skin. Furthermore, the GYH LED mask activates procollagen synthesis by stimulating fibroblasts, leading to an increase in collagen that improves skin elasticity and clarity.
Q: How is the dose of the phototherapy mask calculated
A: The dose of the phototherapy mask is calculated in joules per square centimeter (J/cm²), which represents the total energy delivered to the skin. The formula used for the calculation is dose (J/cm²) = irradiance (mW/cm²) × time (second). While low irradiance levels can require longer usage time, irradiance that is too low may not have any effect, regardless of the extended use time. Most home phototherapy products on the market have an irradiance below 5mW/cm², but the GYH LED Light Therapy Mask is designed with an irradiance of 30mW/cm², ensuring a highly effective using.
Q: Why choose red, near-infrared, and blue light instead of the common seven-color light on the market
A: These three lights are the only three kinds of light that have been proven effective by the scientific community. These are also the only three FDA-approved lights. The effects of other lights do not have enough support from sufficient scientific research, so we do not use them.
Q: Why combine red and near-infrared light therapy
A: According to research by GYH experts, wrinkle reduction devices that use red LEDs alone are not as effective at reducing signs of aging or improving the skin's overall texture and skin tone, and its effects are greatly enhanced when combined with near-infrared light that penetrates deeper into the skin, exert the result of 1+1>2. So we combine red and near-infrared light, and when you choose "Red" mode, both lights will be on at the same time (near-infrared light is invisible, so the naked eye can't see it).
Q: Does the number of lamp beads matter
A: Just as a flock of sheep can't compare to a lion, more bulbs don't mean a more powerful mask. The light power density (irradiance) of the lamp beads plays a more critical role. The high-quality lamp beads imported from Germany used by GYH can reach the irradiance value of 30mW/cm² with only 40 pieces to achieve the best effect. Most of the products on the market that are less than two hundred dollars have an irradiance value of less than 5mW/cm², although their number of lamp beads may exceed one hundred.
Q: Can phototherapy masks completely replace other skin care and anti-aging products
A: No, in fact, the right skin care products can make the effect more significant. A 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 operating time and optical power density 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.
