u/Alternative-Bid2388

I’m fairly new to sun bed tanning. I’ve been using a stand up bed. I started at 3 mins and have been increasing my time slowly. Last week I did two 5 minute sessions which I tolerated well so today I increased to 7 mins but burned (mainly on my stomach with some spots on my back and upper legs). Any suggestions on how to treat it and heal it quickly? I’m a little surprised by how just two mins caused me to burn.
