Should I wear sunscreen in the car?

Yes, wear sunscreen in the car. UV rays come through windows, and it adds up faster than you think. Windshields block most UVB but not UVA, and side and rear windows offer even less protection, causing daily skin damage on your commute. A basic SPF 30 broad-spectrum sunscreen applied in the morning is fine, and reapply or use a sunscreen stick on your driver-side arm and cheek if you drive a lot.
