Tanning bed need some advice.?

I am starting to go tot a tanning bed again and was wondering how come my face burns so bad and chest but everything else seems to take forever to tan?My legs and arms hardly ever tan but my tummy does a little but my back chest and face burns. Ido not want my face very tan anyways just the rest of my body but it tends to gets the most is it because its not as dry as som parts of my body? If i put sunscreen on my face before tanning and my swedish beauty everywhere else could this maybe work, Please help!
