it does depend on what type you get ( there are 100s to choose from )

and they all do diffrent things, it also depends on if you are tanning from the sun or a bed

basicly its like this.. I am a HT model, so I would promote my brand lol but if you are tanning in a bed get Australian.. its the best bed tanner you can get. (swedish bueaty is made by the same people too)

If you are tanning from outside get Hawaiian tropic.. but get the oil.

Lotion-bed
Oil-sun

Tanning in a bed is safer, it is safer to have a tan when going out side in the summer as well.. Sunburns are what causes cancer.. but tanning lotions dont come with spf.. you wouldnt tan if they did.
