Function of Different Light colour

Red light
The wavelength of red light is 630nm-700nm, which has the functions of diminishing inflammation, relieving swelling, relieving pain and relieving itching. Red light has no strong thermal effect, and has
stronger penetrating power than ultraviolet light, and can act on the deeper tissues of 2-5cm. As red
light can directly reach the skin submucosa, light energy can be absorbed by tissue cells, which can
improve cell activity, promote protein synthesis and energy metabolism, enhance the phagocytosis of
white blood cells and accelerate blood circulation. Whitening skin, shrinking pores, diminishing
inflammation and relieving pain.

Blue light
The wavelength of blue light is 430nm-450nm, which has the effect of quickly inhibiting inflammation. Through photodynamic effect, porphyrin in skin enzymes is stimulated and a large number of singlet
reactive oxygen species are released, thus destroying Propionibacterium acnes and reducing
inflammatory reaction, which can minimize the formation of acne, with quick effect, short course of
treatment and few adverse reactions. Eliminate acne, improve bloodshot and control grease.

Yellow light
The wavelength of yellow light is 570-600nm, which can relieve and treat sensitive skin and skin in
allergic stage. It can promote the recovery of the brick wall structure of skin, speed up the repair of skin
barrier function, restore skin luster and improve the dullness. Remove spots, desensitize, accelerate
healing and improve immunity.

Orange light
The wavelength of orange light is 600-630nm, which is milder than red light and stronger than yellow
light. It can promote blood circulation, strengthen metabolism and thyroid function. Orange light has a
good softening effect on arteriosclerosis, cerebral sclerosis and coronary atherosclerosis. It can also
promote appetite and treat emaciation and anemia. Beauty function: prevent skin dryness, enhance skin
elasticity, stretch wrinkles and stretch marks, and delay skin aging. Prevent dryness, increase elasticity
and accelerate metabolism.

Light blue light
The wavelength of light blue light is 480-520nm, which has the effect of calming and relaxing nerves, obvious analgesic and calming effects on sensory nerves, and good phototherapy effects on
hypertension, hemiplegia and neurasthenia. It can increase the feeling of tranquility, soothe and relax, neutralize, balance and stabilize, and can treat psychological diseases. Cosmetic effect: rough skin, wrinkles, blackheads, acne and acne caused by fatigue. Calm nerves, repair skin, soothe nerves and help with the sleep.

Purple light

The wavelength of purple light is 400-430nm. The main function of violet light is to play an anti-
inflammatory and bactericidal role, mainly aiming at acne symptoms on the skin, preventing local acne

from growing repeatedly, improving acne, dredging lymph and astringing acne. This therapeutic instrument is widely used in the treatment of inflammatory acne, and has the
functions of diminishing inflammation and promoting wound healing of damaged skin tissues such as
pressure sores. Application departments: Dermatology, Burn Department, Rehabilitation Physiotherapy Department, Plastic Surgery Department, Obstetrics and Gynecology Department, Orthopedics Department, etc.

Mixed light
The wavelength of mixed light is 400-700nm, and its main function is to accelerate tissue metabolism.
