Sunburn is an injury to the skin from ultraviolet light. The redness and pain are the body clearing away damaged cells, which is why they arrive hours after the exposure rather than during it. The skin heals in about a week. Some of the DNA damage underneath does not.

Overview
A long-term inflammatory condition that mainly affects the center of the face. It can cause flushing, lasting color changes, sensitive skin, and acne-like bumps.
It is an ultraviolet injury.
Sunburn is inflammatory skin damage caused by excessive ultraviolet exposure.
Symptoms follow exposure.
Warmth, tenderness, swelling and color change develop afterwards; severe burns may blister.
Cool weather still counts.
Ultraviolet damage occurs even when it feels cool or redness is hard to see.
Unusual reactions have causes.
A severe burn after little sun can reflect a photosensitizing medicine or condition.
Erythematotelangiectatic rosacea Type 1 · Redness, flushing and visible vessels
Papulopustular rosacea Type 2 · Bumps and pimples
Phymatous rosacea Type 3 · Thickened skin
Ocular rosacea Type 4 · Eye involvement
Redness Hot, tender skin in sun-exposed areas.
Blisters Fluid-filled blisters in severe burns.
Peeling Skin flaking as it heals.
Rosacea involves inflammatory activity and unusually reactive blood vessels in facial skin. These changes can produce flushing, persistent color changes, visible vessels or bumps, with different features in different people.
Excess ultraviolet exposure injures skin cells and triggers inflammation. Increased blood flow and swelling cause soreness and warmth, and damaged surface cells may later peel away.
Rosacea. Rosacea Usually 30–60 Usually begins in adulthood, often between ages 30 and 60. Starting ages can vary.
Sunburn. Can occur at any age after enough ultraviolet exposure.
Rosacea involves overactive blood vessels and immune signals in the facial skin. Demodex mites, which live on everyone's skin, may also play a part.
Inflammation, sensitive skin, and changes in blood-vessel responses play a part. The skin barrier may be affected too. The exact cause is not fully understood.
Sunburn is damage to skin cells from ultraviolet light. The redness and pain come from the inflammation that follows.
It often runs in families and is more common in people with fair skin, though it occurs in all skin tones.
Rosacea can run in families. Several inherited factors may contribute; there is no single gene that explains every case.
Fair skin, red hair and freckles mean less natural protection from melanin.
Evidence labels come from each condition’s own treatment list.
The one over-the-counter active with real evidence behind it in rosacea. At 10 percent it reduces the bumps and some of the redness, and it is better tolerated by reactive skin than acids or retinoids. Start every other night over moisturizer. The 15 percent prescription gel works better if this is not enough.
A mild anti-inflammatory that also helps the barrier hold water, which is the part of rosacea it is most useful for. Some people find it takes the edge off redness and stinging. It will not clear bumps and it does nothing for visible vessels, so treat it as support rather than treatment.
Sold widely for facial redness on the strength of small studies. It is soothing, it is unlikely to irritate, and some people like how their skin feels on it. There is no good evidence it changes flushing, bumps or visible vessels, so do not let it delay a prescription that would.
An anti-inflammatory painkiller works on the actual mechanism of a sunburn, which is inflammation, and it helps most when it is started in the first few hours rather than added on day two. Take it regularly for the first day or so rather than only when the pain peaks. If you are pregnant or breastfeeding, ask the doctor managing your pregnancy which pain relief is appropriate.
One percent hydrocortisone can take the edge off a small, sore area for a few days. Use it on unbroken skin only, never on blisters or open areas, and not over large parts of the body. It is a mild help rather than a fix, and if the burn is big enough that you want to cover it all, that is a burn worth having looked at.
Benzocaine and lidocaine sprays sold for sunburn cause allergic rashes on inflamed skin often enough that they are not worth using. The relief is short, and an allergic reaction on top of a burn is a considerably worse week. Cool compresses and an anti-inflammatory painkiller do the same job without that risk.
Cooling and pleasant on a burn, and it is what most people reach for first. The trial evidence that it does anything beyond that is thin. Keep it in the fridge if you like it, choose a plain gel without added fragrance or alcohol, and do not expect it to shorten anything. It is comfort, not treatment.
Its job here comes later, on peeling skin and on any blister that has opened, where it stops the new skin drying and cracking and reduces the itch. Use it under a loose non-stick dressing rather than an adhesive one. It is not for the first day on an intact, hot burn, where a thick greasy layer traps heat and makes things feel worse.
Often the best single treatment for the bumps and pus-filled spots, because it works on the Demodex mites and on the inflammation at the same time. Once a night, a pea-sized amount for the whole face. It usually beats metronidazole head to head, and it does nothing at all for flushing or visible vessels.
A prescription-strength gel or foam for the bumps, and one of the better options if your skin is too reactive for other creams. It also helps the marks rosacea leaves behind on deeper skin tones. Expect stinging for the first week or two, which usually settles if you apply it over moisturizer.
The longest-established prescription cream for rosacea bumps, used once or twice a day, and generally very well tolerated. It is a reasonable first choice and a common maintenance treatment once things are controlled. Newer options often work a little better, and none of them touch the redness itself.
An antibiotic put on the skin rather than swallowed, for the bumps. It suits people who would rather not take tablets, or who cannot. It is newer and usually more expensive than the older creams, and like them it does nothing for flushing or vessels.
A gel that narrows facial vessels and takes the redness down for several hours at a time. It treats nothing — it borrows time, and everything comes back when it wears off. Some people get rebound redness worse than they started with, so test a small area before you use it on the whole face and before any event that matters.
The same idea as brimonidine, using a different vessel-narrowing drug, applied once each morning. Rebound redness is reported less often with it, which is why some people move across after a poor experience. It still only lasts the day, and it does not stop rosacea progressing.
A stronger steroid cream, sometimes prescribed for a few days on a severe burn that hydrocortisone has not touched. It reduces the inflammation and the soreness a little. It does not change how long the burn lasts or repair any of the damage underneath, and it goes on unbroken skin only, never on blisters or open areas.
An antibiotic ointment for the specific situation where broken blisters have become infected, which shows as increasing redness, swelling, heat or pus. It is not for a plain burn and does nothing for one. If the infection is spreading beyond the burnt area, antibiotic tablets are needed instead.
Low-dose Doxycycline. A 40 mg dose taken once a day, deliberately too low to act as an antibiotic — it is used purely for its anti-inflammatory effect, which means it does not drive antibiotic resistance. This is the usual next step for moderate to severe bumps when creams alone are not holding them, and it also helps ocular rosacea. It is normally stepped down to a cream once things settle.
An alternative tablet for the bumps when doxycycline does not suit or has not worked. It is used at full antibiotic doses, so it is generally kept for shorter courses. It can cause dizziness, and rarely a blue-gray discoloration of the skin with long use, so it is not the first tablet reached for.
Accutane at a low dose. Low-dose isotretinoin under specialist care, for severe bumps that tablets and creams have not controlled, or for early skin thickening. It works well, and it is not a cure — rosacea usually returns after the course. It requires strict pregnancy prevention and monitoring, so it is a considered decision rather than a routine step.
Low doses of propranolol or carvedilol are sometimes tried when flushing is the dominant problem and nothing else has touched it. The evidence is small studies rather than trials, and they lower blood pressure and slow the heart, so they do not suit everyone. Worth asking about only after triggers, laser and light have been addressed.
The treatment of choice for visible thread veins and settled background redness — the parts of rosacea that creams and tablets do not touch. It targets the blood in the vessel and closes it. Expect a course of about three sessions rather than one, expect bruising for a few days at stronger settings, and expect occasional top-ups, because rosacea carries on making new vessels.
IPL. Light rather than laser, and about as effective as pulsed dye laser for diffuse redness across the cheeks, with less bruising. It is often the better choice when the problem is a general flush rather than a few distinct threads. It needs an experienced practitioner and a test patch on deeper skin tones, because the wrong settings can cause lasting pigment change.
A longer wavelength that reaches deeper, larger vessels — the thicker blue-red threads beside the nose that pulsed dye laser sometimes leaves behind. It is also the device more often chosen for deeper skin tones, because it passes over surface pigment more safely. It is less useful for general background redness.
Used to reshape a nose that has thickened, by removing the excess tissue layer by layer. This is the answer for rhinophyma, since creams and tablets do not reverse it. It is a real procedure with real downtime of a couple of weeks, and results are strongly dependent on who does it.
Asked about constantly, usually as a home device. Red and near-infrared light is mildly anti-inflammatory and it is very unlikely to do harm. There is no good evidence it clears rosacea bumps or removes vessels, so it is a pleasant addition rather than a substitute for the treatments that do.
Botox. Very small amounts injected into the surface of the skin, not the muscle, to reduce flushing and background redness. Early studies are encouraging and dermatologists do use it for stubborn flushing. It is off-label for rosacea, it is not usually covered, and it wears off in a few months.
Rosacea runs in flares and quiet spells. The outlook is good - it does not scar, it is not dangerous, and treatment controls most of it. It does not go away, so the goal is long-term control on the lightest treatment that holds it.
The worst of a sunburn arrives after you have gone indoors. Nothing makes it heal faster - aftercare makes the week bearable and prevents complications, but does not undo the injury. The DNA damage does not fully reverse, and repeated burns, particularly in childhood and adolescence, contribute to actinic keratoses, squamous cell carcinoma, basal cell carcinoma and melanoma decades later.
Rhinophyma — thickening of the nose
Over years, the skin of the nose can thicken, enlarge and take on a bumpy, uneven surface. It develops slowly and only in a minority of people, and it is far more common in men. Creams and tablets do not reverse it once it is established, which is the strongest practical reason to treat rosacea early. It has nothing to do with drinking, despite an old and persistent belief that it does.
Ocular rosacea
Rosacea in the eyes causes gritty, dry, burning, watery or red eyes, crusting along the lash line and repeated styes. It affects a large share of people with rosacea, it can turn up before any skin changes, and it does not track with how bad the face looks. It is the part most often missed, and it needs treating in its own right, so mention your eyes even if nobody asks.
Lasting redness and visible vessels
Left to run for years, the redness stops fading between flushes and becomes the background color of the cheeks and nose, with fine vessels showing as permanent red threads. Creams do very little for this stage. Laser and light treatment work well on it, but preventing it is far easier than removing it, which is the practical argument for treating rosacea early.
Blisters that get infected
A blister means the injury went deeper into the skin. An intact blister is a sterile cover over an open wound, and popping one lets bacteria in and can turn a burn that would have healed cleanly into one that scars. Leave them alone. If one opens by itself, keep it clean, use plain petrolatum and a non-stick dressing, and get it looked at if the area becomes hot, swollen or starts oozing pus.
Heat illness and dehydration
A large burn is not only a skin problem. Fever, chills, headache, nausea, weakness, dizziness and intense thirst come from a big area of inflamed skin losing fluid alongside hours in the heat. It is often called sun poisoning, which it is not. Children and older adults reach this point sooner. It needs shade, fluids and, if there is confusion, fainting, vomiting or very little urine, same-day medical care.
Skin cancer decades later
This is the complication that never looks like one at the time. Repeated blistering sunburns, particularly in childhood and adolescence, are associated with a substantially higher risk of melanoma later, and ordinary cumulative exposure drives most other skin cancers. No amount of aftercare undoes it. It is why a pattern of burning every summer is worth a conversation, and why a history of repeated burns is a reason to arrange a skin check.
Seek help for repeated flushing, lasting facial changes, products that repeatedly sting, or persistent gritty eyes and eyelid irritation.
Tell the clinician about dry or gritty eyes and sore lids, even when facial symptoms seem mild.
Get prompt help for extensive blistering, dehydration, fever or severe pain; babies and young children need a lower threshold for assessment.
For most people it persists. It responds well to treatment, and many people keep it almost entirely controlled for years on light maintenance. The goal is control rather than cure, and treating early prevents the parts that become permanent.
No. Food and drink trigger flushing in someone who already has rosacea; they do not cause it. Hot drinks, alcohol and spicy food are reported most. Your triggers are personal - a couple of weeks of notes tells you more than any generic list. Cutting out foods that are not triggering you achieves nothing.
Sometimes, carefully. Both irritate, and a weakened barrier means many people cannot tolerate them at usual strengths. If you try, add one at a time, two or three nights a week over moisturizer, and stop if it stings. Never start one during a flare.
Laser and intense pulsed light are the only treatments that meaningfully remove visible vessels and reduce established redness, and results last a long time. Not permanently - rosacea continues and new vessels form, so most people need occasional maintenance sessions. Expect a series rather than one. On deeper skin tones, ask for an experienced practitioner and a test patch.
It can be both, and they feed each other. Hot flashes cause repeated flushing, and repeated flushing makes rosacea more visible. Rosacea flushing stays on the central face with bumps, visible vessels and sensitivity, while hot flashes involve the whole body, sweating and a sudden onset. Mention both to your doctor - managing one usually helps the other.
Yes, and worth doing if it helps. Green-tinted primers and color-correcting products neutralize redness well, and mineral foundations are generally well tolerated. What matters more than the brand is how you take it off - a gentle cream or micellar remover, not scrubbing or a wipe.
Redness appears within two to six hours, peaks around twelve to twenty-four hours, and settles over three to seven days, with peeling toward the end. Blistering burns take longer and can leave marks for months. Nothing shortens it.
Not really. Peeling is dead skin being shed; the damage is already done. Moisturizer reduces itching and cracking. Do not pull the flakes off - that exposes tender new skin.
No. An intact blister is a sterile cover over an open wound and lowers the risk of infection and scarring. If one opens, keep it clean, use plain petrolatum and a non-stick dressing, and have it checked if the area becomes hot, swollen or oozes pus.
Each burn adds to a lifetime total rather than deciding anything on its own. Repeated blistering sunburns, particularly in childhood and adolescence, carry a substantially higher risk of melanoma. Ordinary cumulative exposure drives most other skin cancers.
Usually a medicine that increases sensitivity to ultraviolet light - some antibiotics, diuretics, anti-inflammatories, retinoids and others. Plant sap, especially lime juice, does the same in streaks, and recent peels or laser lower the threshold. Ask a pharmacist rather than stopping any prescribed medicine yourself.
No. A tanning bed delivers a concentrated dose of ultraviolet light and causes the same DNA damage. Using one before the age of 35 carries a notably higher risk of melanoma. The tan is the injury response, so no version of deliberate tanning avoids it.
