The main benefit of using sunscreen is to protect against UV radiation. Sunscreen contains active ingredients that absorb, reflect, or scatter sunlight, thereby reducing the amount of UV radiation that penetrates the skin. This is crucial because exposure to UV radiation can lead to sunburn, premature aging, and an increased risk of skin cancer. Regular use of sunscreen helps to shield the skin from these harmful effects, promoting overall skin health.

While preventing moisture loss is important for maintaining skin hydration, it is not the primary function of sunscreen. Sunscreen is primarily focused on protecting the skin from UV rays. Enhancing skin glow is a desirable effect that can result from healthy skin, but it is not a direct benefit of sunscreen use. Similarly, while some products may have benefits in treating acne, sunscreen does not specifically address this condition. Its primary role remains UV protection, making it an essential component of a skincare regimen for everyone, regardless of skin type or condition.
