I have acne prone skin myself and I personally like to use the Lorac FACE selfTANtalizer Face Bronzing Gradual Self-Tanner. I like that it has added ingredients like antioxidants A,C and E to protect the skin from environmental damage. The Lorac line was also created for people with sensitive skin.
Another option is the Dr. Dennis Gross Alpha Beta® Glow Pads. It's formulated with Vitamin D and gently delivers streak free color to the skin.
