Winter , summer , monsoon - use sunblock or sunscreen in all seasons. However, the need is a little more in the heat. Intense sunlight is especially harmful for our skin from 9 am to 4 pm. Even if the sky is cloudy, you need to use sunblock or sunscreen before going out. At least 20 minutes before going out, apply it on the skin , especially on the hands , feet , face , neck and neck like a normal cream. Also apply sunscreen lip balm on the lips. If you are out for a long time, use it again for 2 to 3 hours in a row. If you want to do makeup, apply sunblock first, then use makeup or other cosmetics after 20 minutes.
