FAQs

Always protect your eyes and healthy skin first. Always wear UV-protective goggles during treatment. In addition, healthy skin should always be covered with clothing or sun cream with a high sun protection factor.
Always start your course of treatment with a low dose or short treatment time, and only increase this gradually if you do not notice any symptoms of sunburn.
Keep a personal patient diary in which you record all individual treatments, noting the areas of the body treated and the dose used. This will help you to find your individual dose setting and adjust it as required.

The following contraindications must be taken into account in UVB therapy:
• Tumourous skin lesions
• Pathological photosensitivity of the skin, e.g. xeroderma pigmentosum
• Porphyria
• Active tuberculosis or other active inflammatory processes
• Hyperthyroidism
• Lupus erythematosus
• Concomitant medication with the potential to cause skin damage

The most common side effects of UVB therapy are erythema (sunburn) and dry skin.

You can enhance the effectiveness of UVB radiation by carefully removing any flaky skin and moisturising the skin before starting the treatment. You should also remove any creams or make-up that may have been applied.

A course of treatment consists of individual sessions, each lasting just a few minutes, which are repeated 3 to 5 times a week. Depending on the severity of the condition, 20 to 25 sessions should be sufficient for the skin symptoms to subside.

UVB radiation has only a palliative effect, but this enables the skin lesions to heal. As part of a reduced maintenance regimen, it is usually possible to maintain this improved condition, provided that excessive cumulative UV exposure can be ruled out.

The service life of the UV lamp is technically limited, so its effectiveness may indeed diminish after prolonged use (around 500 operating hours). If you feel that your device is affected by this, please contact us so that we can inspect it and, if necessary, replace the lamp.

No, because the rows of teeth are not only used to part the hair but also act as spacers between the hair and the skin. This is the only way to properly control the UV dose administered during a therapy session. Furthermore, if the distance changes, the dose can no longer be calculated over time, increasing the risk of applying either too little or too much UV radiation to a specific area.

In Germany, the costs of medical aids are usually covered in full by health insurance funds (subject, where applicable, to a statutory co-payment of up to 10 EUR). A mandatory requirement for this is, amongst other things, a relevant prescription or referral from a doctor. To ensure you do not lose your entitlement to reimbursement or to avoid any disputes later on, you should never purchase a device at your own expense in advance without first consulting your health insurance provider. The ‘benefits in kind’ principle of statutory health insurance, for example, prevents any claims for reimbursement. Further information, for example on the claims process, can be found here.
