How can intesity and duration of tanning sessions be calculated for getting a continuously beautiful and brown skin-colour without any risks?
First, we have to understand the idea of healthy tanning. The process is the same in case of sunbathing and using a tanning bed. Unfortunately, the formeris getting more and more difficult by natural sunshine because of the decrease of the ozone layer around the world. However, without light no life exists! Under UV radiation, on the one hand, our skin colour is changing, on the other hand, vitamin D3 is forming in our bioorganism. By the effect of suitable dose of UV B radiation, in the deeper layers of skin the pigmentation process starts, and more and more cells containing this dye material emerge into the upper skin layers, where the UV A radiation oxidizes them, so brown skin colour appears as a defence mechanism. Certainly, from time to time, it is necessary to get new tanning sessions for maintaining this state. It is important to consider that even the optimal tanning makes the skin dry, so for re-establishing the ideal hydration content of the skin adequate solarium cosmetics must be used!
What happens in case of over-tanning?
Too intensive UV B radiation causes fragmentation in the RNS of the cells, and the healthy cells immediately start the reconstruction: they "push out" the damaged cells from among themselves. This process causes inflammatory erythema, and then unwanted peeling. It must not be forgotten that the human skin has a strange ability: it does not forget atrocities against it.
Knowing this information and the skin type the type of lamp, tanning intensity and duration can be declared.
The Chocolate Brown tanning lamps offer a large assortment in intensity, from it lamps 0,3 may be emphasized .
Taking into consideration that the whole UV A and UV B spectrum is 100 %, modern lamps such as the Chocolate Brown "0,3" tanning lamps the UV B rate has been decreased and the UV A rate has been increased, and only the UV A radiation is responsible for oxidation/tanning. (Earlier in the case of strong lamps the division was 5% for UV B and 95% for UV A.) Technical characteristics and the tanning beds are different, but for a specific type, these parameters are unchanging, so only by variating the power of lamps can the needed intensity of the tanning bed be set. That is why our company developed three lines of lamps, including the "0,3".
Scientific literature defines six types of human skin. In our area here in Central Europe there are typically only (the first) four types.
