That would be AWKWARD!..I wouldn't raise my arms in public to get a tan. I'd most probably do that in my garden, problem is the UK have zero sun as you well know..
I'm going to tan everyday for 3-4 weeks I think my body requires a high dosage and I can deal with the sides I don't get any except a facial flush. I think I've wasted about 10mg with virtually no sun in that time have only around 5mg where I've had UV which just isn't enough for a skin type 1. There was a post I read where this guy said he does not burn I'm exactly the same, not even red after a day. I've seen a difference on my face and near my genitals area and my freckles are much darker on my arms which make them look darker also.
