Hi Lorraine! Oh my gosh, I’m terribly sorry to hear about your bad reaction to the new foundation. And I hope you’ve stopped using that foundation immediately!! It’s possible that you developed an allergic reaction to one or more of the ingredients in the foundation, but you may also have a very sensitive skin. Try to find a foundation that has no preservatives, chemicals and is fragrance-free. The Body Shop has mineral foundations that contain natural products, so maybe start there.
