If you have recently been sun tanning, we recommend waiting 2 weeks before using your handset. You should wait 48 hours to tan after using your handset. The same applies for sunbeds. We advise removing all artificial tan before using our handsets, as the light energy may be more attracted to the pigments in the skin, rather than the melanin in the hair. You can reapply the tan after your session once the skin has relaxed.
