Sun Safety During Daily Commutes

Vehicle glass is engineered for safety and impact resistance, not for total ultraviolet spectrum blockage. While front windshields are typically treated to minimize UVA transmission, the side windows of most passenger vehicles remain vulnerable points of exposure.

This creates a lopsided geography of sun damage, often manifesting as deeper lines or uneven texture on the side of the face and arms closest to the driver-side window. Proper coverage before you turn the ignition is a prerequisite for routine maintenance of your skin condition.

1. Prioritize exposed zones. Begin by applying a broad-spectrum mineral or chemical filter to the left side of your face, ears, and neck. Do not neglect the back of your hands and the bridge of your nose, as these areas face the glass directly. Use a nickel-sized amount for the face to ensure a consistent, non-patchy film.
2. Extend to the driver-side arm. The arm resting on the door panel or the console receives the highest concentration of light. Apply product from the tips of your fingers up to your shoulder. If you prefer long sleeves, ensure the fabric has a high density to prevent light infiltration.
3. Account for reflected glare. Light does not only enter directly; it bounces off the asphalt and dashboard. Ensure the lower half of your face and the undersides of your arms are sufficiently coated. A light dusting of powder with SPF can provide an extra layer if you are prone to sweating in a hot vehicle.
4. Maintain interior hygiene. Clean any residue from your palms before gripping the wheel to ensure a firm hold. If you find yourself in the car for more than two hours, consider a physical barrier such as a lightweight driving glove. Close the process by securing your seatbelt.

Glass is not a wall; it is a filter that requires a companion.
