SkinCeuticals Ultimate UV Defense SPF30

Reviewers say SkinCeuticals Ultimate UV Defense SPF 30 is a great option for sensitive skin because all of the ingredients are encapsulated, leaving less chance of irritation. Users at MakeupAlley.com and Amazon.com say the formula is very moisturizing -- so much so that several say they to use it in place of a daily moisturizer. A few say the sunscreen is too thick and heavy for use in the spring and summer, but it's common for skin to change with the seasons.

Because it relies on a physical sunscreen, SkinCeuticals can leave a white cast on skin, but several reviewers say that can be minimized by using only a small amount. Paula Begoun says the sunscreen is effective but complains that it doesn't contain any antioxidants -- especially considering the company's strong promotion of the good-for-skin ingredients.
