The majority of sunburns that occur are first-degree burns, which are characterized as being very superficial and quick to clear up after 3-5 days of rest and home care.   Second-degree or third-degree burns are not as common but they are much more serious. A second-degree sunburn penetrates the second layer of the skin, known as the epidermis, which often results in redness and blistering. Third-degree sunburns, which are the most serious, reach the layer of fat below the skin and can destroy the nerves. This can result in lasting skin and nerve damage.   Second- and third-degree sunburns require medical attention to be treated effectively. If you’re not sure what type of sunburn you have, it’s always best to air on the side of caution and book in with your primary care physician. You may also be able to consult with your doctor over the phone to determine whether an in-person visit is necessary.
