Help! I don't "do" the sun, trying to slow down aging and avoid skin cancer

Anyway, I usually use a lotion type self tanner. I found some L'Oreal spray bronzer stuff on sale and really love the results I'm getting, but my skin is SO dry!
Anyone know how long I should wait to moisturize after using the spray? I don't want to mess it up

But I can't continue without lotion, my skin is really dry
