1.What is phototherapy？
Light therapy is also called phototherapy. It is a skin care treatment that uses different wavelengths of light, including red, blue, yellow, green, ultraviolet, and near infrared view. During LED therapy, we select different frequencies of light to treat different depths of the cortex depending on the skin care problem. Most commonly, the LED lights used for skin care are yellow, red and blue.
2.Are LED masks safe to use?
Home LED devices are largely safe - as long as you choose the right device and protect your eyes. Choose a mask that's marked as FDA-approved and wear shaded or opaque goggles. You can even find face masks with the right glasses.
Prolonged exposure to blue or red light can harm your eyes if you don't have proper eye protection. Some people with eye-related conditions such as ocular albinism or congenital retinal disease or those taking medications that make them more sensitive to light may experience blurred vision, eye pain, eye irritation or changes in vision. More serious problems include irreversible loss of peripheral vision or complete impairment.
Who is not recommended to use？
People with a history of skin cancer and systemic lupus erythematosus should avoid this treatment, Sodha says, as should those with retinal diseases such as diabetes or congenital retinal disease. The list also includes people who take light-sensitive medications such as lithium, certain antipsychotics and certain antibiotics.
Avram suggests that people of color should be more cautious when using these devices because sometimes the color can change.
3.How does the led light therapy work？
LED light therapy uses color wavelengths of visible light that have specific skin benefits. Due to aging, skin disease or trauma, healthy skin cells are damaged and unable to properly renew themselves. Using specific wavelengths of light, red, blue and near infrared light, we can deliver clinically proven doses of light energy to target receptors within our cells. When these receptors are stimulated, cellular activity increases, resulting in the activation of many different natural bodily processes. This includes a 200% increase in cell renewal, increased collagen production, which increases skin plumpness and reduces fine lines and wrinkles.
4. The Benefits of phototherapy
Different colors of LED lights point to different cortex. Different colors of LED light therapy can help relieve different symptoms. In general, it can help solve the following 20 situations:
Reverses sun damage
Assists with pain relief
Reduces stretch marks
Reduces redness on the skin
Fights against Acne bacteria
Increases Collagen production
Deduces blemishes and freckles
Reduces symptoms of psoriasis
Calms eczema & promotes rapid healing
Reduces spider veins and broken capillaries
Promotes elastin production for tighter skin
Cell regeneration and renewal
Eases swollen capillaries
Increases lymphatic flow
