Sunscreen, also known as suntan lotion, is a product that is used to protect the skin from the suns harmful ultraviolet (UV) rays. These UV rays can cause severe sunburns, premature aging, skin cancer, and other skin damage. Using sunscreen is a critical way to protect your skin from sunburns. It also helps prevent premature aging and skin cancer. Generally, the higher the SPF, the better the protection. Sunscreen should be applied to all exposed skin at least 15 minutes before going out in the sun. It should be reapplied every two hours, as sweat and water can reduce its effectiveness. It is important to choose a sunscreen that is suitable for your skin type. Products with a higher SPF are ideal for those with fair skin, while those with darker skin tones should choose products with a lower SPF. There are also many other options available such as sunscreens that have additional ingredients for added protection, as well as ones that are specifically formulated for certain activities such as swimming or sports. Whether youre at the beach, hiking, or just running everyday errands, its important to use sunscreen. By making sunscreen a regular part of your routine, you can help keep your skin safe from the suns harmful rays and prevent skin damage.
