We often think pale skin is no longer desirable in summer season. So, many of us want to get tanned. However, we don’t have enough time to get a suntan on the beach. The desire for a quick suntan has led to the invention of sprays and lotions that darken the skin without lying under the sun. They have brought some changes in our vacation plan. We don’t have to spend our time on the beach. We can use those products at home lying down on a sofa and get what looks like the same suntan just for a few dollars.
