Moisturise after a fake tan to maintain it, but be careful to avoid products that have a lot of perfume ingredients as they tend to contain alcohol which can dehydrate the skin and make the tan crack. It’s recommended that you re-apply it no more than every two weeks. It’s very dependent on the individual though as a lot of people prefer a deeper colour. It’s a good idea to have a professional tan at the end of a spa day as you can’t use the pool and facilities for a period of time afterwards without washing it off.
