Please bear in mind that dha is absorbed into the to first 25% of the epidermis, so it may not be possible to completely remove any unwanted tan.
Sienna x tan wipes are a godsend, but they are only really effective within the 1st hour after applying the tan.
Things like pineapple juice, papaya juice and lemon juice (all fresh and not from a carton) contain fruit acids or alphahydroxyacids (aha's) which will help slough off the dead cells but nothing will remove the tan completely.
Orange hands and index fingers are a hazard of the job, so try and make sure you wear your gloves right up till the last minute, even folding up your cubicle and picking up and used towels.
Advise your clients that they should be aware of where they place their hands in the development time and if they are one of those people who touch themselves in their sleep (oooh Er?), adise them to sleep with a pair of socks on their hands. This is also good pratice for brides b4 their wedding, so to avoid orange hands in wedding photos.
