What are the typical effects of UV exposure on the skin?

  1. Increased hydration and elasticity

  2. Scar healing and skin rejuvenation

  3. Premature aging, sunburn, and increased risk of skin cancer

  4. Improved skin tone and texture

The correct answer is: Premature aging, sunburn, and increased risk of skin cancer

The typical effects of UV exposure on the skin primarily include premature aging, sunburn, and an increased risk of skin cancer. Ultraviolet (UV) radiation from the sun can cause damage to the skin's DNA, leading to changes that result in noticeable signs of aging, such as wrinkles, loss of elasticity, and pigmentation changes. Sunburn is an immediate response of the skin to excessive UV exposure, characterized by redness, inflammation, and pain. Moreover, prolonged and unprotected UV exposure is a significant risk factor for developing various types of skin cancer, including melanoma and non-melanoma skin cancers. In contrast, increased hydration and elasticity, scar healing, improved skin tone, and texture are effects that are not typically associated with UV exposure. These may describe the benefits of proper skincare or treatments, but they do not reflect the consequences of being exposed to UV rays.
