Which statement about sun exposure for children is correct?

The statement regarding sunscreen not being used on infants under 6 months of age is correct because infants have very sensitive skin that is more prone to irritation and absorption of chemicals found in sunscreen. As a result, it is generally recommended to avoid applying sunscreen to infants younger than 6 months. Instead, it is advised to keep infants in the shade, dress them in protective clothing, and use hats to shield them from direct sun exposure.

In contrast, while some UV exposure can cause skin damage, sunburn primarily arises from UV-B rays, not UV-A, which points to the inaccuracies in other options. Sunscreen application timing is important, but dermatologists typically recommend applying it about 30 minutes before going outdoors rather than 5 minutes. Additionally, the recommendation for a minimum SPF often suggests using a broader spectrum with an SPF of 30 or higher for adequate protection, making SPF 15 less optimal in many guidelines.
