I can understand that you blame a particular brand for your problems, but are you sure it is the brand? You said that you got a bad sunburn, but what product did you use? What was the SPF factor and how often did you apply it?
I have a link to two sites, one is Neutrogena and the other is St.Ives.
Try looking for another brand on line. Look at a drugstore site and I know you'll find some good, reasonable priced products.
