About 2 years ago, I developed an allergy to synthetic fragrances, and have since then stopped using anything that lists "fragrance" in its ingredients. At first, the reaction would be only on my chin, and would consist of very small whitehead pin-head pimples. The rash would stick around for a few days, then flake off, and everything would be okay.
At that time, I switched to all-natural products that either had natural fragrances using essential oils or no fragrances at all; everything ranging from shampoo, soap, make-up, deodorant, detergent, dish washing liquid, house cleaning solvents, i even went as far as getting fragrance free hand soap at work and taking bed sheets and covers with me on vacation because the detergent used at hotels made the rash flare up even more.
Recently, the rash has appeared again and has been getting much more intense. It spreads from my chin and all over my right cheek, slightly on the left cheek, and on my forehead. The whitehead pin-head pimples have also started being extremely itchy. My skin feels oily, but after a few days, it gets very dry and starts flaking.
I am now wondering if there is something else that I'm allergic to - whether the allergy is food. The rash only appears on my face, as described above. It has appeared only once on my chest and upper back - and it is unsightly! Should I be patch tested again? What could it possibly be?
