Razor burn tips??

I was hoping to try a self tanner and so I shaved my legs yesterday. But apparently I misjudged when I should shave because I have the worst razor burn right now..I'm trying everything I can to help it heal and go away. But now I'm afraid I can't use the tanner...any tips on preventing it and healing it?

I've tried nearly everything I can think of. Certain shaving creams, baby oil, moisturizer, exfoliating..baking soda masks on my legs, aloe vera gel, etc.

This picture was after some home remedies and some of the redness had went away a bit..
