Brief summary
Hamam is a common spa treatment. During a Hamam, some of the outermost layer of the skin is removed. The investigators believe that partly removing a protective skin layer might increase the risk of sun burn, especially for skin that has not been exposed to sun for a long time. The aim with this study is to assess if Hamam-treated skin is more susceptible to sun burn compared with untreated skin.
Interventions
