I am allergic to parabens, lanolin and sodium benzoate plus some other undiagnosed chemical allergies (i still react to some products without those chemicals, but we havent been able to pin point what yet.). I also have severe eczema.
I have tried every paraben free, lanolin free, preservative free, sensative skin sunscreen out there. The ONLY thing that I can use is Vanicream sunscreen. It is relatively expensive though. It costs us $15 for a 4 oz tube. Most places do not carry it in the store though. We usually have to order it. Our local pharmacy usually has 1 or 2 in stock but CVS, Walgreens, etc have never had it in stock. They've always had to order it (at least where i've lived).
