How does it work?
Seecret® enables your skin to rejuvenate itself continuously in a natural manner. The specially tailored light spectrum stimulates the production of collagen and elastin, which leads to visible improvement of the skin. Discover Seecret® and experience the sensation of a healthy, attractive appearance. Only you know the secret...
Structure of the skin
Our skin consists of several layers. The protective outer layer is called the Epidermis or scarf skin. Beneath this is a deeper lying layer called the Dermis or true skin. It is this layer that gives the skin its strength; it consists of a dense structure of connective tissue containing collagen and elastin fibres that keep the skin firm and supple. As we grow older, the production of new cells diminishes, reducing the number of collagen and elastin fibres. As a consequence the skin gradually loses its elasticity, resulting in lines and wrinkles.
Approximately 45% of sunlight is visible light we can see with our eyes. In addition to visible light, sunlight also includes components we are hardly able to detect: ultraviolet (UV) and infrared (IR) light. Various scientific investigations have proved that visible light produces a number of responses in the skin. Infrared light, for example, is known to penetrate the skin deeply where, among other things, it improves the blood circulation. Collagen light falls within the colour spectrum of light and is yellow, orange and/or red. The colour spectrum is the bandwidth of light visible to the naked eye. It spans the range of wavelengths from approximately 380 to 760 nm. Collagen light occupies a range of frequencies just below that of infrared light, running from around 600 to 760 nm.
Effect of visible light on the production of collagen
Scientists have observed that exposure of the skin to yellow, orange and/or red light leads to higher production of collagen. This works as follows: In addition to collagen and elastin, the skin also contains fibroblasts. These are special cells that synthesize collagen. Light penetrates the skin to a depth of 10 mm, causing the fibroblasts to grow and divide. Production of collagen and elastin are stimulated in this manner, improving the elasticity of the skin.
