4 Rules of Using the Sunscreen

Living in a tropical country certainly requires special protection for skin that is not burned by the scorching sun. Ignoring the skin from exposure to direct sunlight can cause skin cancer.

Known, only about 20 percent of women are wearing sunscreen every day, so in the end about 68 percent of skin cancer, according to a survey conducted by Allure magazine via Facebook.

There are a few things you need to consider when using sunscreen:

* If you're the type of woman who has a job in the outdoors, you may need care products containing retinol (a derivative of vitamin A). Apply a thin top layer of your skin to solve your skin from redness and brown spots, so suggestions dermatologist Fredric Brandt.

* One bottle of sunscreen alone is not enough, because you have to apply it repeatedly. "One ounce is the right size for each application of sunscreen, as well as for the sequel. So if a 12 ounce bottle of sunscreen, it can be used for 12 times it is used, and that is enough," says Patricia Wexler, a clinical professor of dermatology department of the Mount Sinai Medical Center in New York City. So, start set the alarm on your cell phone every two hours to remind you to re-apply sunscreen on your skin.

* If you are outdoors for 30 minutes or more, use a sunscreen that contains Mexoryl SX or Parsol, then followed with a sunscreen that contains Z-Cote or titanium dioxide. "Both types of sunscreen that is not 100 percent perfect (to protect the skin), and any ray through the first layer will be caught by the second layer," says Miami dermatologist origin, Leslie Baumann.

* Think-think again before you use sunscreen wipes. FDA (Food and Drug Administration, a kind of Food and Drug Control Agency in the United States) is reviewing the effectiveness of their usefulness, along with a shampoo that contains SPF.
