If you stay for too much in the sun, your skin will have to suffer. In order to avoid the loss of moisture from the skin, dark patches or premature aging, be sure you chose the right sunscreen. A good sunscreen protects against both UVA and UVB rays. If you have a sensitive skin, choose a lotion with SPF of 20 and above. Also apply the sunscreen about 20 minutes before exposure to the sun and reapply it if you stay for a long time in the sun.
To avoid wrinkles in a natural way, use Vitamin-C, that reduces wrinkles and other signs of aging. Found in oranges and lemons, L-Ascorbic acid, a certain type of vitamin C, contained in some creams or gels soak up the harmful free radicals before damaging the skin. It also helps slow down the process of aging, but not prevent it.
To protect yourself from pollution in the air, wash your face when you get home with a good soap to remove dirt and other bacteria from the skin. If you are outdoors for a long time, use a mild cleanser regularly. Use a moisturizer or foundation to shield your skin from pollutants.
