Sun exposure before and after treatment can increase the risk of unwanted pigmentation and sunburn. Avoid significant sun exposure (e.g. sunburns or sun tanning) and artificial tanning for at least 2 weeks before, during and 2 weeks after treatment. When you go outside during this period apply a sun protection factor (SPF) of 30 or above on the treated areas.
Use SPF 30 when sunbathing or artificial tanning for at least 3 months after your last treatment.
