I have a bad reaction to skin cream, can my skin heal on its own without treatment?

[sindiozzy]

I used cream(avon anew with spf) on my face and had a bad reaction, my face got bright red and stung, however there was no rash, no bumps, so my dermatologist said it didn't trigger an immune response. He said usually he would prescribe a cortisone, but since i have rosacea( very mild) he prescribed protopic. It has been 9 days since i have been on pro topic and my skin is burning, i feel my skin may be getting worse not better. My dermatologist said to wait it out 3 or 4 weeks. My question is can my skin heal on its own without the use of medication? Thank You
