What are the symptoms of sunburn?
If you get a sunburn, your skin might feel like it’s on fire — a hot and burning sensation that gets worse when you touch it, even with clothing.
Symptoms of sunburn depend on how severe your burn is. Symptoms may include:

While others may notice your skin turning pink in the sun, unless you’re looking in a mirror, you probably won’t notice sunburn until the pain starts. Your sunburn will go through three stages:
- Pain from sunburn usually starts within a few hours of your burn.
- Your skin will get redder and more irritated, with pain peaking at about 24 hours after your burn. If you have a second-degree sunburn, you’ll start to blister.
- Over the next week or so, your skin may peel and should gradually return to its normal shade. If you have a severe sunburn, this may take a few weeks.
What causes sunburn?
Sunburn is caused by ultraviolet rays. There are two types of UV rays: UVA and UVB. Both types of rays can burn your skin.
Anyone can get a sunburn. But your chance of getting a sunburn increases depending on:
- The amount of time you spend in the sun.
- Certain medications, including antibiotics like doxycycline and Bactrim™, nonsteroidal anti-inflammatory drugs (NSAIDs), retinoids and heart medications (like diuretics).
- Intensity of UV rays. This is affected by the time of day, cloud coverage, altitude and closeness to the equator.
- Ozone depletion, depending on where you are in the world.
- Skin type and color.
- Use of tanning beds without sunscreen.
