Sun blisters are white or clear fluid-filled bumps that form with a sunburn. They are considered second-degree burns, which affect the epidermis (outer layer of the skin) and dermis (layer below the epidermis that includes blood capillaries and nerve endings). As such, they can be highly painful.

Sun blisters usually appear a few hours after sunburn occurs, but they can take up to 24 hours to develop.The type of symptoms you experience depends on the degree of burn. Without protection, your symptoms may be more severe.

Sun blisters typically last a few days to a week depending on the size and number of blisters.There are three degrees of sunburn that are based on the size and depth of the burned skin.The higher the degree, the more severe the burn is.

First-degree (superficial) burnsare typically mild and only affect the epidermis. Symptoms include:

Summary

Sun blisters are a sign of second-degree burns from prolonged exposure to the sun. They can appear in a few short hours after exposure or take up to 24 hours to develop. Sun blisters usually last a few days to a week, but it depends on the size and number of blisters.

Symptoms of second-degree sunburn include the formation of blisters, deep redness, and severe pain. While most cases of blisters can be treated at home, seek immediate medical attention if blisters cover more than 20% of the body.

At-home remedies include drinking extra water, applying soy or aloe vera moisturizer, using a cold, damp compress, and taking a pain reliever. Sunburn ages skin and increases the risk of skin cancer, so take preventive steps to reduce your sun exposure.

While it’s best to plan ahead so you don’t get a sunburn, it can happen due to unexpected circumstances. Get out of the sun at the first signs of redness. While sunburn is common, it can also be a serious condition, especially if it has reached the point of blistering.
