Final answer:
Sunscreen protects skin from UV radiation, prevents skin cancer and premature aging, while concerns about vitamin D deficiency are minimal as minimal exposure is sufficient for production.
Step-by-step explanation:
Using sunscreen is essential for protecting our skin from the harmful effects of UV radiation. While UVB radiation aids in the production of vitamin D, which is crucial for preventing bone disorders, excessive exposure increases the risk of skin cancer and premature aging. Dermatologists recommend obtaining vitamin D through foods or supplements rather than prolonged sun exposure. Sunscreen products come with an SPF rating that indicates the level of protection they provide against UVB radiation. Although there is a concern that sunscreens may block vitamin D synthesis, the body needs only a small amount of sunlight to produce the necessary vitamin. Therefore, the benefits of using sunscreen outweigh the potential risks, helping to keep your skin both healthy and youthful.
