Do you have any allergies to key ingredients? Adverse reactions are commonplace with skin care products and sunscreen is no different. Some users cannot tolerate avobenzone and other chemical sunscreens. Titanium dioxide and zinc oxide are generally considered to be the most gentle sunscreen options perfect for kids and those with sensitive skin. Keep in mind that other ingredients, such as fragrance and preservatives, may also cause a reaction. It's always a good idea to test sunscreen on a small patch of skin before applying it liberally -- especially if you have skin sensitivities.
When comparing the prices of various sunscreens, keep in mind that one bottle isn't likely to last you very long if you're applying it correctly. Experts say the SPF ratings on the bottle can only be realized when you apply enough product. For adults that's one ounce of sunscreen for full-body coverage -- equivalent to two tablespoons or a palmful. Furthermore, for adequate protection, sunscreen should be reapplied often.
