In an article published in The New York Times, dermatologists provided guidance for effective sun protection habits. They stressed that the side and rear windows of cars do not often protect the skin from UV radiation, and long-term exposure may lead to an increased risk of skin cancer. Individuals were advised to install protective window film as well as wear sunglasses, sun-protective clothing such as long sleeves and hats, and sunscreen with an SPF of 30 or greater while in the car. Additionally, those who prefer to use sunscreen spray should hold the can 1 inch from the skin, apply several layers, and rub the sunscreen into the skin to ensure that the spray is most effective. Those who are receiving treatment for acne with tretinoin and isotretinoin or nonsteroidal anti-inflammatory drugs like ibuprofen and naproxen may be at an increased risk of sunburns and should follow the same sun-protective measures. Further, individuals should consider applying a lip balm with an SPF of 15 or greater once per hour, since the lips are also susceptible to UV radiation. The dermatologists concluded that those who do experience damage to their lips following sun exposure should use a cool compress or an over-the-counter steroid cream to reduce pain and irritation.
