Mistake 1: Using Product With Fragrances
It's pretty well known that people are often allergic to scents, so your best bet is to choose fragrance-free products. According to Dr. Wechsler, it's difficult to determine what your trigger is because fragrances are normally a combination of scents — some natural, others chemical.
Her advice is to test a new formula on a small area, rather than your whole face. "I like to apply it right in front of my ear three days and three nights in a row," she said. "Do a little bit, and if you're fine and don't get a rash in that area, then you can do it on your whole face. If it's a body product, then test it on your forearm."
You should also choose fragrance-free detergent and soaps to be extra careful! Anything that touches your skin can cause an outbreak or allergy.
