Does anybody have the experience , or know if sunscreen goes bad from one year to the next? I actually think I've developed an allergic reaction to sunscreen on my face, as my sinuses get really sickly feeling and I just feel like I've got to wash it all off my face. Not breakouts, but beneath the skin, in sinus (behind eyes feeling) about a couple hours after applying it. I bought it fresh only last summer, Neutrogena brand, both the face moisturizer with 15, and the 45 sunblock. I really am quite freaked as I finally settled a couple years ago on thinkin Neutrogena was 'my brand', having never felt this reaction so severely before. But it's downright unbearable now.
