Query: Very expensive petroleum jelly

I purchased this product, at the recommendation of a doctor, without checking the ingredients. When I DID check the ingredients, I found that THE ONLY ACTIVE INGREDIENT LISTED IS PETROLATUM (41%). Petrolatum is petroleum jelly. "Vaseline" is petroleum jelly (100%). Aquaphor lists other ingredients as "Inactive Ingredients."If I could, I would give this products NO stars.
