I think usually there is only a problem with discoloration if you use it for a longer amount of time. Once, I had the worst cyst thing ever in that thin patch of skin beside my mouth where there is no bone, and it stuck out really far and sadly to say, I considered killing myself because of it. Long story short, the derm told me to use hydrocortisone OINTMENT on it, and it actually did heal nicely in a shorter amount of time than usual blemishes. I had no discoloration.
