Exposing the skin to sunlight, and particularly to UV rays, triggers a protective reaction by melanocytes, the cells responsible for skin colouring.
With age, the skin loses its glow, transparency and radiance, and brown spots can appear.
To solve these problems, TALIKA laboratories, experts in specific beauty care, present, in partnership with researchers at the Paris Hospitals, a revolutionary lightening and anti-spot treatment by light:
Light525 skin lightener®
TALIKA laboratories have designed light 525®, a portable device whose light wave (525 nm) regulates the production of melanin, responsible for skin colouring.
The skin becomes more radiant, glowing and lighter and brown spots are diminished: the skin is younger-looking.
How light works in lightening treatments
Light spectrum + drawing
- Light is composed of particles that travel at 300,000km/second, whilst vibrating at a variable frequency.
The low frequencies of these vibrations correspond to invisible waves (radio, satellite, etc.).
If the frequency increases, it becomes detectable to our eyes and enters the realm of visible light (which is composed of a series of colours, from orange to violet).
Beyond a certain frequency, we talk of ultra-violet light, and if we increase it even further, we reach the field of very high energy: X rays and then gamma rays.
- Light 525®, the caring light source.
In the 1970s, NASA, thanks to its experience with space flight, revealed that the cell metabolism is reanimated by visible light. This property of animal cells to respond positively to light makes them similar to plant cells, which cannot live without sunlight: in the same way as during the plant photosynthesis process, light comes into contact with the cells and activates their metabolism.
With the appearance of new light sources such as light590® and light525®, created in the wake of gentle pulsed light, cosmetics is entering a new era.
The principle of light 590® and light525®: use the light rays corresponding to a spread of pure colours ranging from blue to red. These rays, with no heat source, emitted by diodes, activates the cells deep down and obtains spectacular results. Light590® treats wrinkles by reactivating collagen and elastin production.
light525 skin lightener®: clinically proven effectiveness
TALIKA laboratories have therefore designed light525®, a portable device that continuously emits a precise frequency (525 nm) in a controlled manner, to prevent and reduce brown spots and lighten the skin.
Melanocytes synthesise melanin pigments, which are responsible for skin colouring. When melanin is produced regularly and constantly, skin pigmentation is uniform.
With the combined effects of skin ageing and UV rays, melanin production can be affected. The skin loses its glow and, over time, brown spots appear up to 2cm in diameter. They are generally found on the face, hands and forearms.
Moreover, over the age of 50, the skin undergoes transformations that change the appearance of the pigment spots. The skin becomes thinner. The melanocytes, highly concentrated in dark pigments, get closer to the skin surface and are therefore more visible.
