Never.

The first beauty product you should apply every day is sunscreen, even if it’s cloudy or rainy outside. Why? Good habits start young and if you use sunscreen now, you’ll have gorgeous skin when you’re 50, 60, 70. Remember, the sun’s UV rays can penetrate clouds, car windows, umbrellas, etc. Remember: 2 minutes of casual sun a day at the end of one year = 2 full weeks of sunbathing. Over the short term, this UV-induced damage can produce a painful burn; over the long term it causes premature aging of the skin.

A sunscreen product acts like a very thin bulletproof vest, stopping the UV photons before they can reach the skin and inflict damage. Also, it helps in avoiding puffy eyes and fine lines. But apart from using a sunscreen, one should also use other skin creams for worries of wrinkles and dark circles.
