I used tretinoin cream almost 3 months ago and I only used it 3 times. It has left me with red blotchy skin on my face. I didn't over use it (pea sized amount), was not out in the sun, and wasn't using any other irritating products. An esthetician told me that it's probably inflammation in the deeper layers of my skin. Will this ever go away? It's been almost 3 months with no improvement. Also, my skin has been very VERY oily since using the cream. Will this ever return to normal?
