Sun can seriously damage your skin and make it rough, dull and dry let alone making it dark. If you are exposed to the sun for a long period of time you will see that the skin which is exposed to the sun is getting dark and dull due to the ultraviolet rays of the sun. So try to stay away from the sun’s rays from 1pm in the after till 4pm as the YV rays are the strongest during that span of time.
You can opt for shades when you go outside to save you from sun. You can also go for a hat and cover your neck with a stylish scarf. To stay away from the sunlight you can always tend to wear long sleeved clothes so that the minimum amount of skin is exposed. Buy a sun screen cream which is at least of SPF 15 and its better if you can get a cream more than SPF 15 to protect you from sun.
