Experts Weigh in on Aquaphor's Potential to Cause Lip Sunburns
Wearing Aquaphor, a petroleum-based product, on the lips in the sun can cause sunburn, swelling, blisters, and even skin cancer. Lips are a combination of muscle and connective tissue and are automatically positioned to be exposed to the sun just like the rest of your face. Dermatologists warn against using petroleum- and oil-based products in the sun and instead recommend using an SPF lip balm. If you have a mild sunburn, use a cool compress on your lips to help with swelling and to decrease the heat in your lips. Additionally, finding a chapstick with an SPF of 15 or higher can protect against sun damage.
