Can I use canola oil to get a tan?
Sister is correct and you do not need even oil but it is batter to use it. Now you must understand that 30 minutes of morning or evening sun is best any thing more and you need to use Tanning solution with SPF 50, this is the thing in the solution that protect you against skin cancer so be care full some have thing that keep you from blistering out also so reconsider the whole idea of getting tan for graduation. 30 minutes per day will also provide enough vitamin “D” and in few days you will have a good tan, but it will depend on your skin type, some like me get tanned very fast, other burn/blister very fast and yet other cannot acquire it soon enough.
