While everyone should wear sunscreen all year, it is more crucial in the summer when the days are longer, the sun is stronger, and when people spend more time outside. If a person spends any time outside, they have probably heard at least one caution about the need to wear sunscreen. Using a sunscreen with at least SPF 30 broad-spectrum UV protection is highly recommended. Regardless of the weather, using sunscreen is critical since it is one of the most efficient ways to protect the skin from dangerous ultraviolet rays. The proper product can make all the difference, and today we will show how to choose a good sunscreen. Tips to pick the perfect sunblock for your skin 1. Broad spectrum This mark indicates that the sunscreen protects against both UVA and UVB rays. UVB rays, which are the primary cause of sunburn and skin cancer, are blocked by all sunscreens. UVA radiation, on the other hand, can cause skin cancer and premature aging. The term "broad spectrum" can only be applied to items that pass a specific test. Products that are not broad spectrum must state that they only protect against sunburn and do not protect against skin cancer or aging. Read: Best Health Clubs and Gyms in Dhaka in 2021 2. SPF A sun protection factor (SPF) number is printed on every bottle of sunscreen. The SPF indicates how much protection the product provides from the sun's rays. However, a greater SPF does not guarantee that the skin will be protected. A product with an SPF of 30 enables 3 percent of UV rays to hit and be absorbed by your skin, whereas a product with an SPF of 50 only allows 2 percent, a 50 percent difference. The issue is that by choosing a lotion with a higher SPF, one may believe that they are getting more protection and hence do not need to apply sunscreen as often. Though an SPF30 should allow a person to spend 30 times more time in the sun than exposed skin, and an SPF50 should allow him to spend 50 times more time in the sun. It is possible that one will start burning far sooner than that. When someone sweats or swims, the sunscreen is washed away, and they lose protection. Therefore, a sunscreen with an SPF of at least 30 should be used by everyone. People who have fair skin should opt for 50. Read Winter Skincare: How to care for sensitive skin during winter
