Up Until Recently, I Have Not Done Much To Take

Up until recently, I have not done much to take care of my skin. About 3-4 days ago i began a skin care regimen (i.e.: toner, cleansing, moisturizing) and since then my acne has become awful, and very red. Before this, I would never wash my face, sleep with makeup on, never take my makeup off, etc. Is it possible this is because my skin is not used to the cleansing, and it is letting all the filth out of my skin?
