I think I may be allergic to some ingredient in a lot of face moisturizers and foundations. My face has recently broken out into tiny bumps (which has happened to me before, mostly on my forehead and around my mouth/chin) and they usually dissipate within a few days. This time the bumps have become itchy and flaky. They are on my entire face, around my nose, under my eyebrows etc. However, they are not on my neck. What can I do to help alleviate this? With the numerous ingredients listed on face products now, is there any way to tell which ingredient may be causing this reaction so I can avoid it in the future? Thank you.
