A visit to the dermatologist is a good idea. In the meantime, I'll tell you what my dermatologist told me (I started a thread about finding a toner for sensitive skin):
1. Avoid very hot water
2. Avoid dryer sheets and fabric softeners and detergents with additives/fragrance
3. Cleanse with Cetaphil, Dove, Purpose or Lever 2000.
4. Moisturizers could be Cetaphil moisturizing cream, Eucerin, Aquaphor, Purpose or vaseline.
This is for a few weeks to calm the skin down. I'm still using the Cetaphil and purpose moisturizer as well as trying some toners that the ladies here recommended. So far, so good.
Good luck.
