I read all the reviews, bought the winterskin, slapped some on as it said nothing happens for a few days - wrong! Lovely uneven tanned legs - this due to method of application not product!! Thought I\'d have a few days to build up a tan. The knees and ankles went the darkest so need to take care there. Very nice product to use. Next time I will be more careful. Nice to have a bit of a tan when I wore the sandals to work.
