Read the following essay, which lacks a conclusion: Sunscreen is a hot topic every summer. Dermatologists recommend wearing it every day to protect your skin from solar radiation. But skeptics say it can cause more harm than good by exposing you to dangerous chemicals and causing Vitamin D deficiency.

There are two good reasons to wear sunscreen: to protect your health, and to protect your looks. Excessive exposure to sunlight can cause skin cancer. Over time, it also makes skin saggy and wrinkled. Numerous studies have shown that regular use of sunscreen reduces the occurrence of skin cancer, and also keeps skin smoother and more elastic.

In contrast, there is little evidence that sunscreens currently on the market contain ingredients that are harmful when absorbed. It doesn’t take much sunlight to produce all the Vitamin D needed for good health, either.

Which of the options below is the most effective conclusion to the essay?

1)Walt Whitman said, “Keep your face always toward the sunshine – and shadows will fall behind you.” Easy to for him say when he always wore a thick beard and big hat, but everyone else should either seek out those shadows or put on some sunscreen. Poetry can soothe your soul, but only sunscreen will protect your skin.

2)Dermatologists recommend wearing sunscreen every day to protect your skin from the sun’s radiation, although some skeptics worry about exposure to dangerous chemicals and Vitamin D deficiency. Many studies have shown that regular use of sunscreen is good for you. There is little evidence it is harmful.

3)Sunscreens work in two ways. Some use minerals to form a physical barrier that reflects radiation away from your skin. Others include chemical compounds that absorb the sunlight before your skin does. When used properly, both types of sunscreen can protect your skin from damage.

4)In closing, the evidence for wearing sunscreen is clear and bright, while the arguments against it are partly cloudy at best. Use it every day, and your skin will look and be healthy.
