Sunburn: First Aid and What Not to Do

A perfect day by the water. Sun, warm sand, a good book. You applied sunscreen in the morning - but then there was a swim, then another, the towel, a nap... and somehow you never got back to reapplying. In the evening, in the shower, the water on your back stings like fire. The skin is hot, tight, intensely red. A classic: sunburn.

And now the questions come up. Slather on something greasy? Apply ice? Or just wait it out? What should you do so it isn't even worse tomorrow?

The good news: you can effectively relieve most sunburns at home if you know how to go about it. The bad news: several popular "home remedies" can clearly make matters worse. Today we'll go through it step by step - what actually happens to your skin, how to give it first aid, what you absolutely should not do, and when a sunburn is already a matter for a doctor.

What happens to the skin during a sunburn

A sunburn is not "the skin tanned too much". It is real damage to the skin caused by ultraviolet radiation (UV), mainly UVB. The radiation damages the DNA of skin cells and triggers an inflammatory reaction. The body responds defensively: it dilates blood vessels (hence the redness and the feeling of heat), and inflammatory cells flow into the damaged area (hence the swelling, pain, and tenderness).

Importantly, a sunburn develops with a delay. As you leave the beach, you may feel fine. The full symptoms usually appear after several to many hours, and the peak of discomfort often falls on the second day. That's why it's hard to judge "by eye" while sunbathing how much sun is already too much - by the time you notice the redness, the dose has already been exceeded.

Degrees of sunburn severity

Sunburns differ in depth and severity:

• Superficial (mild) sunburn - the skin is red, hot, tender, and tight, but not visibly damaged. After a few days the redness subsides, often with slight peeling. This is the most common scenario.
• Deeper sunburn (with blisters) - in addition to redness and pain, fluid-filled blisters appear on the skin. This is a sign that the damage reaches deeper. Such a sunburn heals longer, and complications such as infection occur more easily.
• Extensive sunburn with general symptoms - when the sunburn is accompanied by fever, chills, severe weakness, nausea, or dizziness, we are already talking about a reaction of the whole body. This is a situation requiring consultation with a doctor.

The scale has practical significance: you can take care of mild redness at home, but an extensive sunburn with blisters or fever is another league - more on that in the next part.

First aid for sunburn

If you have a mild or moderate sunburn, a few simple steps will bring the skin real relief and support healing.

1. Get out of the sun and cool the skin

The first step is obvious but crucial: stop the exposure. Move into the shade, into a cooler room. Then cool the burned skin - this relieves pain and limits the inflammatory reaction. The following work best:

• A cool (not icy) shower or bath
• Cool, damp compresses made of soft material, applied for around fifteen minutes

Cool gently and in moderation - the goal is pleasant coolness, not a thermal shock.

2. Moisturize and nourish the skin

Burned skin loses water and becomes dried out. After cooling, it's worth moisturizing and soothing it. Gentle products work well here:

• Products with panthenol (dexpanthenol) - this is the classic for soothing sunburns. Panthenol supports the regeneration of the epidermis and has a moisturizing and soothing effect. It is available as a spray (foam), cream, or ointment. A spray is often convenient, because you apply it without touching the painful skin.
• Soothing and moisturizing products - light after-sun gels and emulsions, products with aloe vera, soothing lotions. Choose simple formulas, without irritating additives.

Apply the products gently, without rubbing them in by force. In the first hours, avoid thick, greasy occlusive ointments - more on that in a moment in the section on mistakes.

3. Drink water

A sunburn means a loss of fluids for the body - both through the damaged skin and often through overheating or spending the day in the heat. Drink more water than usual. Adequate hydration supports regeneration and improves well-being. A signal of fluid deficiency is dark urine, a dry mouth, and headaches and dizziness.

4. Relieve pain and inflammation

If the sunburn is painful, you can reach for over-the-counter pain and anti-inflammatory medications - for example paracetamol or nonsteroidal anti-inflammatory drugs (such as ibuprofen). The latter also have an anti-inflammatory effect, which can be helpful with a sunburn. Use them according to the package leaflet and do not exceed the recommended doses. If in doubt - especially if you take other medications - ask the pharmacist about the right choice.

5. Protect the skin until it heals

Burned skin is exceptionally sensitive to another dose of sun. Until the redness disappears, keep the burned areas in the shade and under clothing. Wear loose, breathable clothing made of soft materials, so as not to irritate the skin with friction. After healing, the skin may peel slightly - do not peel off the epidermis, let it come off on its own.

What NOT to do with a sunburn

This is perhaps the most important part of the article. Around sunburns circulate plenty of "grandmother's remedies" that sound sensible but in reality cause harm. Here are the mistakes you'd better avoid:

• Do not slather the skin with butter, lard, oil, or greasy cream. A greasy layer acts like a compress that traps heat - it "locks" it in the skin instead of letting it cool down. In addition, it hinders healing, and with damaged skin it increases the risk of irritation.
• Do not apply ice or ice cubes directly to the skin. Cooling yes, but ice directly on burned, damaged skin can lead to an additional cold injury. Use cool water or cool compresses, not ice.
• Do not pierce blisters. A blister is a natural dressing - it protects the deeper layers of skin from infection. By piercing it, you open the way for bacteria. If a blister bursts on its own, do not peel off its skin, and keep the area clean.
• Do not use irritating cosmetics. Scrubs, products with alcohol, heavily perfumed lotions, cosmetics with acids or retinol - all of this will additionally irritate the burned skin. During the healing period, opt for minimalism and gentle products.
• Do not scratch off the peeling epidermis. Peeling is a stage of healing. Forcibly tearing off the epidermis exposes immature skin and delays regeneration.
• Do not go back into the sun "because it's almost gone". Burned skin needs time. Another exposure before it heals is a straight path to deepening the damage.

The rule is simple: burned skin is helped by coolness, moisture, and rest, and harmed by grease, ice directly on the skin, mechanical irritation, and more sun.

When a sunburn requires a doctor

Most sunburns heal on their own within a few days. There are, however, situations in which you should not delay a medical consultation. See a doctor if:

• The sunburn is extensive - it covers a large area of the body
• Numerous or large blisters appear - especially if they occupy a significant area of skin
• General symptoms occur - fever, chills, severe weakness, nausea, vomiting, dizziness, headache. They may indicate overheating of the body or heatstroke - a condition that requires a quick response.
• The sunburn covers the face, eyes, or particularly sensitive areas
• Signs of infection appear - increasing pain, swelling, redness around the wound, purulent discharge, fever a few days after the sunburn
• The sunburn affects a small child or an infant - more on that separately below
• You feel strong anxiety and don't know how to proceed - a consultation is always a good idea

General symptoms after a day in the sun - especially fever, confusion, weakness - are a signal to act quickly. Overheating of the body and heatstroke can be dangerous.

Children - special caution

Children's skin is thinner and more delicate than that of adults, and the mechanisms protecting against the sun are not yet fully developed. Children burn more easily, lose fluids faster, and overheat faster. That's why you should take sunburns in the youngest more seriously.

A few rules:

• Infants under 6 months of age should not be exposed to direct sun at all - their skin is too sensitive for it.
• In the case of a sunburn in a small child, decide on contacting a doctor more readily than for an adult - especially when blisters, fever, tearfulness, drowsiness, or reluctance to drink appear.
• Do not use products or medications "from the shelf for adults" on children without making sure they are appropriate for the given age. Read the package leaflets, ask the pharmacist.
• Watch hydration - a child with a sunburn should drink regularly.

The best protection for a child, however, is avoiding sunburns: shade, breathable clothing covering the skin, a head covering, and a suitable sunscreen.

Prevention in a nutshell

The best sunburn is the one that doesn't happen at all. You'll find a full guide to choosing sunscreens in our separate article on sunscreen - here just the most important rules:

• Avoid the sun during the hours of greatest intensity - roughly from 11:00 to 15:00 the UV radiation is strongest
• Use a sunscreen with an appropriate SPF - apply it generously and reapply it, especially after swimming and drying off with a towel
• Use the shade - an umbrella, trees, a canopy
• Wear protective clothing - breathable, but covering the skin, a head covering, sunglasses
• Remember that UV also works through clouds and in water - a cloudy day or a swim do not protect against a sunburn

Prevention is not only more convenient than treating sunburns - it also protects against the long-term effects of excess sun, such as premature aging of the skin and an increased risk of skin cancer.

What it's worth having in your summer first-aid kit

The sun season lasts for months, and sunburns usually happen in the evening, when the pharmacy is already closed. That's why it's worth having a ready set at home:

• A product with panthenol - spray or cream, for soothing sunburns
• A soothing after-sun product - gel or emulsion to moisturize irritated skin
• A painkiller - paracetamol or a nonsteroidal anti-inflammatory drug, for pain and inflammation
• A sunscreen - the best "medicine" for sunburns is their prevention
• Dressings and a disinfectant - in case of burst blisters and minor wounds

These are products that are good to buy in advance and together - as one summer first-aid kit, instead of running for individual packages at an emergency moment.

Most frequently asked questions

How quickly does a sunburn appear?

With a delay. As you leave the sun, you may feel fine - the full redness, pain, and swelling usually appear after several to many hours, and the peak of the symptoms often falls on the second day. That's why you can't judge "on an ongoing basis" how much sun is too much - it's better to err on the side of caution and protect the skin in advance.

Does aloe vera help with a sunburn?

Products with aloe vera have a cooling and moisturizing effect, so they can bring relief with a mild sunburn. Choose products with a simple composition, without alcohol and strong fragrances that could additionally irritate the skin. Aloe vera, however, will not replace a consultation if the sunburn is extensive or blisters appear.

Can I sunbathe if my skin is still peeling?

Better not. Peeling skin is still in the process of healing, and the fresh epidermis underneath is immature and exceptionally sensitive. Another exposure to the sun during this time easily leads to the next sunburn. Wait until the skin fully regenerates, and be sure to use a sunscreen.

Can a sunburn cause a fever?

Yes, with extensive sunburns, a fever, chills, and a general feeling of being unwell may appear - this is a reaction of the whole body. Such symptoms, especially in combination with weakness, nausea, or dizziness, may also indicate overheating of the body. This is a signal to consult a doctor, and with intensified symptoms not to delay.

Does a dark complexion protect against a sunburn?

A darker complexion contains more melanin, which provides a certain natural protection - but it is not full protection. Anyone can get a sunburn, regardless of skin color. Sunscreen, shade, and sensible exposure are needed by everyone.

Summary - what's worth remembering

✅ A sunburn is real damage to the skin caused by UV radiation - and it develops with a delay, the peak of the symptoms is usually the second day.

✅ First aid is coolness, moisture, and rest - cooling the skin, products with panthenol, drinking water, a painkiller in case of pain.

✅ Do not slather the skin with grease or apply ice directly to the skin - one traps heat, the other causes additional damage.

✅ Do not pierce blisters - they are a natural dressing protecting against infection.

✅ Go to a doctor when the sunburn is extensive, there are numerous blisters, a fever or general symptoms appear, or when a small child got sunburned.

✅ Children require special caution - their skin is more delicate, they burn and overheat more easily.

✅ Prevention is best - sunscreen, shade, protective clothing, and avoiding the sun during the hours of greatest UV intensity.
