If it were me I would look for a cream, like the Roden and Field Sunless tan cream or a more natural cream. I likely would not do a spray tan, because the amount of fumes that could be inhaled, which in most cases DHA is the main ingredient in spray tans and probably should not be inhaled. Just my 2 cents and not a professional opinion though.
Re: Should I get a spray tan before my vacation? Is it safe?
