What should be done before and after a treatment for permanent hair removal?

In order to maximize the success of the treatment, the following points should be considered:
The skin area to be treated should be as pale as possible. Tanned skin can react with side effects such as burns. This means: no residual tan from vacation or solar studio. No sunbathing! This also applies to the time after treatment; Must be free and thoroughly cleaned; Must not be epilated, plucked, or treated with depilatory cream for 1 month until treatment; Should be freshly shaved – on the eve or on the day of treatment. Unshaven areas of the skin can not be treated because all hair must be removed before use. Must not show any inflammation.
