Seecret ensures that your skin repairs itself in a natural way and continuously renews. The specially tuned light spectrum of the collagen lamps in the Seecret devices stimulates the production of collagen and elastin, which leads to a clear improvement of the skin. Read on below and find out exactly how this works.

Structure of the skin

Our skin is made up of several layers. The protective outer layer is called the Epidermis or the epidermis. Below this is a deeper layer called the Dermis or dermis. This layer gives the skin firmness and consists of a dense construction of connective tissue containing collagen and elastin fibers that keep the skin firm and supple. As we age, the production of new cells decreases, leading to a decrease in collagen and elastin fibers. This makes the skin less supple and fine lines and wrinkles appear.

Collagen light

About 45% of sunlight consists of visible light that we can perceive. In addition to visible light, sunlight also contains components that we largely cannot see, namely ultraviolet (UV) and infrared (IR). Several scientific studies prove that visible light triggers various reactions in the skin. Infrared light, for example, is known to penetrate deep into the skin and, among other things, improve blood circulation. Collagen light falls within the color spectrum of visible light and is yellow, orange and/or red. The color spectrum is the bandwidth of light that you can see with the naked eye. It runs at a wavelength of about 380 nm to 760 nm. Collagen light is close to infrared and ranges from about 600 nm to 760 nm.

Scientists have observed that exposure of the skin to yellow, orange and/or red light leads to a higher production of collagen. This is done as follows: in addition to collagen and elastin, the skin also contains fibroblasts. These are special cells that produce collagen. The light penetrates up to 10 mm into the skin and causes the fibroblasts to grow and divide. The production of collagen and elastin is stimulated, which improves the elasticity of the skin.
