The optimum dose for all indications corresponds to the factor 0.7 - 0.9 MED (=
minimal erythema dose). In order words, for treatment to be successful it is important
to perform irradiation to a level just below the erythema limit (i.e. until a slight
reddening of the skin becomes visible, which however does not become fully
discernible until after around 6 to 12 hours).
The MED varies from patient to patient and depends on the skin type (see table 1).
Your doctor will tell you in which class (1 - 6) you belong.
For the sake of simplicity we have based the following descriptions on skin type 2
(applies to the majority of Central Europeans).
For the therapy success it is essential to pre-treat your skin or scalp, i.e. to remove
scale.
Guide values for skin type 2, first exposure :
approx. 60 seconds for each irradiated area of the body;
approx. 5-6 minutes for the entire hair-covered scalp.
The duration of the first exposure for hair-covered scalp depends on the extent of the
hair covering and its thickness. The purpose of the comb is to part the hair and allow
the UV radiation to get through to the scalp (see Chapter 4.3. T
).
RECOMMENDATION
The guide value for the percentage increase per exposure for skin type 2 is 25% to
30%.
In case of overdose (noticeable and visible sun burn or pronounced
reddening of the skin), shorten the irradiation period or discontinue
treatment.
