What Cosmetics Can Be Use to Cover a Keloid?

Do to a keloid that formed 4 inches in my chest. I no longer can wear v-neck or low-cut top dresses. Too embarrassing! I hate shopping, because I have to be selective in my chioces, which means I end up with a turtle-neck,crew top or halter style top. I tried the injections, but they were so painful I couldn't bear it anymore. If I could just find a thick cover cream to blend in with my caramel skin,I would try a low cut top. Any suggestions? Help! Desperate!
