I received this from my dermatologist after she completed a laser treatment. I used it faithfully when going outside for the first 60 days post treatment. Then returned to my usual one, another doctor recommended, quality, spf 50 product and got sunburned. I was so angry. Ever since then, this Mineral Creme is my only sunscreen. This product works. The drawbacks other reviewers noted can be overcome. It does go on with a noticeable white layer and feels slightly greasy, but I would rather say very smooth. The white lets you know you’ve applied it without misses and then fades after 5 minutes. The smoothness makes it easy to apply, and makeup (foundation and powders) applies easily over it. Then everything sets. Use a little power under eyes to keep mascara from moving to your skin. Using this protocol, I have great success with this product.
