Chest redness?

My chest is constantly very red with little pimple-like bumps. I thought it was acne and went to a dermatologist and she told me what I have is not really acne but some incurable skin condition called k___ ptorosis. Something like that. Anyway, I took antibiotics and applied steriod cream and it's still there! Is there any other way to cure this acne-like skin condition? I also have it on my entire back.
