lately ive been breaking out on my forehead. ive been using so many acne treatments from sacylic acid to benozoyol peroxide and NOTHING is working. the rest of my face has 1, maybe 2 pimples, but on my forehead theres a breakout of too many to count! im really getting stressed out because the pimples are so huge i cant even cover them with makeup! what is an effective treatment for my acne that i can buy at any local drugstore?
