User manual PHILIPS HB171

[. . . ] Do not tan the face more often than once a day. Avoid intensive skin exposure to natural sunlight on the same day as a UV session. If you have any symptoms of illness, if you take any medicines and/or apply cosmetics which increase skin sensitivity, you should not have a UV-session. Special care is also necessary in cases of pronounced individual sensitivity to ultraviolet. [. . . ] In fact there are two processes which produce tanning, and they are simultaneously effective: - "Indirect tanning". Primarily UV-B stimulates the production of a substance called "melanin", which is necessary for tanning. The effect does not show until a couple of days after the sunbath. The UV-A and also a part of the visible light cause quicker browning without reddening or "getting sunburnt". UV and your health After an excessive exposure to ultraviolet (from the natural sun or from your face tanner), the skin may develop sunburn. Beside numerous other factors, such as excessive exposure to the natural sun, improper and excessive use of your face tanner will increase the risk of skin and eye disease. The nature, intensity and duration of the radiation on one hand, and the sensitivity of the individual on the other, are decisive on the degree in which these affects can occur. The more skin and eyes are exposed to UV, the more risk increases of diseases such as inflammation of the cornea and/or conjunctiva, damaging of the retina, cataract, premature aging of the skin and skin tumours. certain medicines and cosmetics increase the sensitivity to UV. Therefore, it is of great importance - that you follow the instructions in sections "Important" and "UV sessions: how often?"; - that you select the advised operational distance of 10 cm (approx. 4"); - that you do not exceed the maximum amount of tanning hours per year (i. 30 hours or 1800 minutes); - that you always wear the provided goggles while tanning. You may have one UV session per day, over a period of five to ten days Allow at least 48 hours between the first two sessions. After such a course, you may rest the skin for a while. Approximately one month after a course your skin will have lost much of the tan. You might then decide to start a new course. On the other hand, it is also possible to have one or two UV sessions per week after a course has elapsed in order to keep up the tan. Whatever you may prefer, make sure that you do not exceed the maximum amount of tanning hours. For this face tanner the maximum is 30 hours (= 1800 minutes) per year. Example: Imagine that you take a 10 day UV course, with a 10 minute session on the first day and 25 minutes' sessions on the nine following days. The entire course then includes (1 x 10 minutes) + (9 x 25 minutes) = 235 minutes. [. . . ] Make sure that no water runs into the appliance. Replacing the tube lamps and/or starters In the course of time (in normal family use after some years) the efficiency of the tube lamps will gradually decrease. If this happens, you may increase the tanning session time or have the tube lamps (and if required the starters) replaced. Have the tube lamps and starters replaced only by authorized service personnel: only these have the required skill and dispose of the original replacement parts. [. . . ]
