Epiduo
"I can't say enough about this product. I suffer from acne cysts that show up every few months. Using epiduo as a spot treatment has been a miracle.  I used to have to seek out a cortisone injection or wait out the long process of allowing the cyst to heal while looking absolutely terrible.  Now with the epiduo the cyst seems to form a head and heal within days of first arriving.  I'd recommend this to anyone who has had the misfortune of dealing with these terrible deep acne cysts"
