The Sunburn Recovery Menu

Sunburn is extremely common. While prevention is better than cure, it’s important to know how to heal a sunburn in case it happens to you. 

Wondering how to treat it? Keep reading for some science-backed remedies that could help.

You know when it’s happened. If you have pale skin, it’s going an angry red colour. It feels sore and prickly. It’s hot to the touch. And you’re kicking yourself for forgetting to slap on the factor 50. 

Most people get sunburnt from time to time. A survey by the charity Melanoma Focus found that 49% of people in the UK experience it at least once per year - so you’re not alone. 

But while the immediate symptoms are usually very unpleasant, it’s the long term consequences that are most worrying. Many studies have found a close link between frequent sunburn and a higher risk of developing skin cancer. 

It goes without saying, but you should do everything you can to avoid getting sunburnt in the first place. But it’s easy to misjudge the weather, forget sun cream, or fall asleep on a sunlounger. In this guide, we’ll look at how to treat sunburn according to scientific research and trusted experts.

What is sunburn?

Sunburn is an inflammatory skin reaction that happens when your skin is overexposed to ultraviolet (UV) radiation. 

Here’s what that means:

• The sun (as well as tanning beds) sends out lightwaves known as ultraviolet radiation
• This damages the DNA in the cells on the outer layers of your skin
• If your skin’s monitoring system decides too much damage has been done, it will destroy the skin cells
• Your body triggers an inflammatory response, sending immune cells to destroy the dead skin cells and sending extra blood to the burned area
• This inflammation causes the redness, swelling, heat, and pain associated with sunburn
• Blisters might develop - they contain fluids that support new skin growth
• Sheets of skin will start to peel away as new skin cells grow and take their place

It usually takes about 3-5 hours for sunburn to show, and it typically peaks 24 hours after the burn happened. 

How long will it take for a sunburn to heal?

So, how long should a sunburn last? It really depends on how bad the burn is. 

There are three degrees of sunburn, depending on which layer of your skin has been damaged:

1. First-degree sunburns: These affect only the outer layer of skin and usually heal within one week. 
2. Second-degree sunburns: These damage the middle layer of your skin, and can take up to two weeks to heal. 
3. Third-degree sunburns: These are rare with sunburn (most third-degree burns are caused by fire or chemicals). They can destroy nerve endings and need intensive emergency treatment, including things like skin grafts. 

First and second-degree burns can usually be treated with home remedies and over-the-counter medication. Second-degree sunburns may sometimes warrant medical attention, especially if the blisters get infected. 

How to get rid of sunburn fast

We get it, sunburn isn’t a good look, so you’ll want to get rid of it ASAP. Unfortunately, there’s no known method for how to get rid of sunburn redness overnight—or even faster.

The reality is, your body needs time to heal. It has to get rid of the sheet of damaged skin and rebuild a whole new layer. There are no quick fixes here. It will just take a few days, or even weeks. 

How to heal a sunburn by helping your body

While it’s not possible to speed up your body’s sunburn repair process, you can help by making its job as easy as possible. Try the following tips and ideas to support your body’s natural processes. 

Stay out of the sun

This is easily the most important thing you can do. As soon as you realise you might be getting burnt, cover up and get into the shade.

Remember that it can take a few hours for sunburn to visibly appear - just because you’re not showing signs yet, doesn’t mean you’re not getting burned. 

If you do get sunburn symptoms, stay out of the sun until the symptoms have completely cleared up. This can be frustrating (especially if you got burned on day one of a two-week beach holiday), but your newly formed layer of skin is delicate. Further exposure is only going to cause more damage. 

If you have to go outdoors, keep your skin covered (particularly over the affected area) and be militant about suncream, hats, and sticking to the shade. 

Rest and recover

As it recovers from sunburn, your body needs to build a whole new layer of skin. It can do this best while you’re asleep. Try and get as much shut-eye as you can in the days after your sunburn. Eating a healthy diet and including some additional protein gives your body the nutrients it needs to build back efficiently. 

Use cool water

That burning sensation you’re feeling is your body’s inflammatory response - and it’s a necessary part of how it repairs itself. Nonetheless, it can be really uncomfortable. 

A cool bath or shower (on a low flow), or simply sponging yourself with a damp cloth, can relieve the discomfort. 

Applying cooling and hydrating gels/creams

These treatments won’t heal your sunburn, but they can soothe the sensation of inflammation. Most pharmacies sell various kinds of aftersun that are designed to relieve sunburn, and it’s safest to go with one of these. 

Many people swear by aloe vera gels - this succulent plant is known to have anti-inflammatory properties (although there’s some doubt about quite how effective it is). 

If you wish to use aloe vera, buy a gel from a reputable brand. While the aloe vera plant you might have growing on your windowsill contains the same stuff, it could also be carrying other bacteria you don’t want anywhere near your damaged skin. 

Drink more fluids

To deal with sunburn, your body draws more fluids to the surface of your skin, where it may evaporate. That means you could become dehydrated more easily. The simple solution is to drink more water than usual. Drinks containing electrolytes can also be helpful, according to the Skin Cancer Foundation charity. 

Over the counter (OTC) medication

OTC medications can help with how to treat sunburn’s more uncomfortable symptoms. Anti-inflammatories like ibuprofen and pain relief like paracetamol can help with managing the soreness. If you find your skin is especially itchy, you could ask your pharmacist about antihistamines or hydrocortisone lotions. They can reduce the itchiness, meaning you’re less likely to scratch at newly formed skin. 

Leave blisters and peeling skin alone 

As tempting as it is to pop blisters or pull at peeling skin, you should try your hardest to leave them be. 

Popping a blister increases your chances of getting an infection, which could lead to complications. If you accidentally break a blister, wash it with soap and water, then cover it with a moist gauze. 

Meanwhile, outer layers of peeling skin are still protecting the new, more delicate layer below. Let nature take its course and wait for it to fall off by itself. 

Comfortable clothing

As your skin repairs, it needs to be able to breathe. Choose lightweight, loose, soft and highly breathable clothing - fabrics made of cotton or bamboo are ideal. Avoid anything that fits tight to the skin as this can irritate it. Rough, heavy or scratchy clothing won’t help either. 

What to avoid when treating sunburn

There are lots of myths and misconceptions about how to get rid of sunburn fast. Here are some of the more important things to avoid:

• Petroleum-based gels (such as Vaseline): These are not designed for treating sunburn. They can trap heat in the skin and cause irritation.
• Ice: Applying ice to your skin will narrow your blood vessels at the surface, meaning they can’t carry as much blood to the area. You want nutrient-rich blood to reach your skin so it can repair the damage.
• Any sunburn-reversing creams: There are a number of brands selling creams that supposedly reverse the effects of sunburn. While there's probably no harm in using these creams once your body has fully healed, the evidence for their effectiveness is pretty limited.

Can certain foods play a role in recovery? 

Over the last few years, a number of studies have been published into the effects of certain foods on sunburn. Specific nutrients as well as entire diets appear to either have a slightly protective effect, or may help with recovery. 

It’s important to stress that diet is not recognised as sunburn protection by any health authorities, and should not replace the usual methods (staying in the shade, wearing sun cream, using protective clothing, hats, and sunglasses). But it’s interesting to know that some foods could play a supporting role. 

• Protective diet: One study suggested that a Mediterranean diet containing certain kinds of fatty acids, antioxidant vitamins, minerals, and phytochemicals could explain why people living in the Mediterranean region have low rates of melanoma (skin cancers) despite living in a place with high levels of UV radiation.
• Polyphenols: A meta-analysis of studies into polyphenols (antioxidant molecules) found in foods like green tea and chocolate concluded that they appear to protect against UV damage. 
• Carotenoids: These are pigments found in many fruits and vegetables, particularly those with an orange or red colour (such as carrots, tomatoes, and sweet potatoes). A number of studies have shown that they may help protect against UV skin damage. 
• Protein: Dietary protein is essential for helping your body repair any kind of damage, including skin damage caused by sunburn. 
• Yoghurt: Other research has found that regularly consuming fermented milk products (such as kefir or yoghurt) appears to mitigate the effects of UV radiation on skin.
• Vitamin D: In an experiment, researchers found that people who took a dose of vitamin D before being intentionally sunburned had less skin redness than people who didn’t take the vitamin D dose.

No one is claiming that diet can completely protect against or ‘cure’ sunburn. However, these studies only further support the notion of following a well-balanced, nutritionally complete diet.
