Sunburn

Show Alternative Names
Solar erythema
Burn from the sun

A sunburn is reddening of the skin that occurs after you are overexposed to the sun or other ultraviolet light.

Considerations

The first signs of a sunburn may not appear for a few hours. The full effect to your skin may not appear for 24 hours or longer. Possible symptoms include:

  • Red, tender skin that is warm to the touch
  • Blisters that develop hours to days later
  • Severe reactions (sometimes called sun poisoning), including fever, chills, nausea, or rash
  • Skin peeling on sunburned areas several days after the sunburn

Symptoms of sunburn are usually temporary. But the damage to skin cells is often permanent, which can have serious long-term effects. These include skin cancer and early aging of the skin. By the time the skin starts to become painful and red, the damage has been done. Pain is worst between 6 to 48 hours after sun exposure.

Causes

Sunburn results when the amount of exposure to the sun or other ultraviolet light source exceeds the ability of melanin to protect the skin. Melanin is the skin's protective coloring (pigment). Sunburn in a very light-skinned person may occur in less than 15 minutes of midday sun exposure, while a dark-skinned person may tolerate the same exposure for hours.

Keep in mind:

  • There is no such thing as a "healthy tan." Unprotected sun exposure causes early aging of the skin and skin cancer.
  • Sun exposure can cause first- and second-degree burns.
  • Skin cancer usually appears in adulthood. But it is caused by sun exposure and sunburns that began as early as childhood.

Factors that make sunburn more likely:

  • Infants and children are very sensitive to the burning effects of the sun.
  • People with fair skin are more likely to get sunburn. But even dark and black skin can burn and should be protected.
  • The sun's rays are strongest during the hours of 10 a.m. to 4 p.m. The sun's rays are also stronger at higher altitudes and lower latitudes (closer to the equator). Reflections off water, sand, or snow can make the sun's burning rays stronger.
  • Sun lamps can cause severe sunburn.
  • Some medicines (such as the antibiotics doxycycline and tetracycline) can make your skin easier to sunburn.
  • Some medical conditions (such as lupus) can make you more sensitive to the sun.

Sun's effect on skin - Animation

The skin uses sunlight to help manufacture vitamin D, which is important for normal bone formation. But sometimes its ultraviolet light can be very detrimental. Within the skin's epidermal (outer) layer are cells that contain the pigment melanin. Melanin protects skin from the sun's ultraviolet rays, which can burn the skin, and over time, could reduce its elasticity and cause a person to age prematurely. Suntanning occurs because exposure to sunlight causes the skin to produce more melanin and to darken. The tan fades as these cells move toward the surface and are sloughed off. Too much exposure to ultraviolet or UV rays can cause sunburn. UV rays penetrate the outer skin layers and pass into the deeper layers, where they can damage or kill skin cells. People who do not have much melanin and sun burn easily should protect themselves by covering up sensitive areas, wearing sun block, limiting their total exposure time, and limiting their sun exposure between the hours of 10 a.m. and 2 p.m. Frequent and prolonged exposure to ultraviolet rays over many years is the chief cause of skin cancer. Examine skin regularly for development of suspicious growths or changes in an existing skin lesion. Early detection and treatment are key in increasing the cure rate for skin cancer.

Home Care

If you do get a sunburn:

  • Take a cool shower or bath or place clean wet, cool wash cloths on the burn.
  • DO NOT use products that contain benzocaine or lidocaine. These can cause allergies in some people and make the burn worse.
  • If there are blisters, dry bandages may help prevent infection.
  • If your skin is not blistering, moisturizing cream may be applied to relieve discomfort. DO NOT use butter, petroleum jelly (Vaseline), or other oil-based products. These can block pores so that heat and sweat cannot escape, which can lead to infection. DO NOT pick at or peel away the top part of the blisters.
  • Creams with vitamins C and E may help limit damage to skin cells.
  • Over-the-counter medicines, such as ibuprofen or acetaminophen, help to relieve pain from sunburn. DO NOT give aspirin to children.
  • Cortisone creams may help reduce inflammation.
  • Loose cotton clothing should be worn.
  • Drink lots of water.

How to treat a sunburn - Animation

We all know that preventing sunburn is the best. But what do you do if you get sunburn? I'm Dr. Alan Greene. Let's talk about that together. When you have a burn from the sun, a radiation burn from the sun, there are a couple of things going on. One is that there's a heat injury. The skin gets hot. You can feel it when you touch it. You can feel it in the burn itself. And another is the outer protective layer is damaged, so the skin can dry out too easily. So the keys to treating a sunburn are to keep the skin cool and moist. So, one great way to do that is with what we call a cool compress. Just take a washcloth. Put some cool water in there and press gently onto the skin. Or you might do a shower - frequent, cool, and lukewarm showers. Either way right afterwards you want to slather on a good moisturizer to try to seal some of that water in, moisture in, preferably a moisturizer that doesn't contain alcohol or any other drying agent. Another time-honored remedy is the Aloe vera plant. And there's some recent studies questioning how effective it really is, but many people swear by it. You cut a little tip off the end of the plant and that gel you rub just directly onto the sunburn itself. And it certainly feels soothing and may help beyond that. Another piece of treating sunburn is to deal with the pain and the inflammation. And for that you might try acetaminophen for the pain or ibuprofen for the pain and inflammation both. Hopefully that will at least take the edge off. But also hopefully that discomfort will help remind you next time to take extra steps to prevent sunburn.

Ways to prevent sunburn include:

  • Use a broad-spectrum sunscreen of SPF 30 or higher. A broad-spectrum sunscreen protects from both UVB and UVA rays.
  • Apply a generous amount of sunscreen to fully cover exposed skin. Reapply sunscreen every 2 hours or as often as the label says.
  • Reapply sunscreen after swimming or sweating and even when it is cloudy.
  • Use a lip balm with sunscreen.
  • Wear a hat with a wide brim and other protective clothing. Light-colored clothing reflects the sun most effectively.
  • Stay out of the sun during hours when the sun's rays are strongest between 10 a.m. and 4 p.m.
  • Wear sunglasses with UV protection.

When to Contact a Medical Professional

Call your health care provider right away if you have a fever with sunburn. Also call if there are signs of shock, heat exhaustion, dehydration, or other serious reactions. These signs include:

What to Expect at Your Office Visit

Your provider will perform a physical exam and look at your skin. You may be asked about your medical history and current symptoms, including:

  • When did the sunburn occur?
  • How often do you get sunburn?
  • Do you have blisters?
  • How much of the body was sunburned?
  • What medicines do you take?
  • Do you use a sunblock or sunscreen? What type? How strong?
  • What other symptoms do you have?

Burns

The depth of a burn determines its severity. First degree burns damage the outer layer of skin (epidermis) and cause pain, redness and swelling (erythema). Second degree burns damage the epidermis and the inner layer, the dermis, causing erythema and blistering. Damage from third degree burns extend into the hypodermis, causing destruction of the full thickness of skin with its nerve supply (numbness). Third degree burns leave scars and may cause loss of function and/or sensation.

Sun protection

Clothing which blocks or screens the harmful rays of the sun (UVA and UVB), in combination with wide-brimmed hats, sunglasses, and sunscreen, are all helpful in preventing damage to the eyes and skin. Any one of these by itself, even the sunscreen, may not be enough to prevent sun damage.

People tan because sunlight causes the skin to produce more melanin and darken. The tan fades when new cells move to the surface and the tanned cells are sloughed off. Some sunlight can be good as long as you have proper protection from overexposure. But too much ultraviolet, or UV, exposure can cause sunburn.

People, especially those who don’t have much melanin and who sunburn easily, should protect themselves. You can protect yourself by covering sensitive areas, wearing sunblock, limiting total exposure time, and avoiding the sun between 10 am and 2 pm.

Frequent exposure to ultraviolet rays over many years is the chief cause of skin cancer. And skin cancer should not be taken lightly.
