Is Cortisone Good for Sunburn? When to Use It

Cortisone cream can take some of the sting and swelling out of a sunburn, but only modestly, and mostly when it goes on early. The over-the-counter strength in most medicine cabinets is the weakest kind, and in some tests it did no better than a plain cream.1PubMed Central. Placebo controlled, crossover validation study of oral ibuprofen and topical hydrocortisone-21-acetate for a model of ultraviolet B radiation (UVR)-induced pain and inflammation Even when a steroid cream calms the redness, it doesn’t repair the sun damage underneath, which is why timing and what you pair it with matter more than the tube itself.2Nature Publishing Group / Journal of Investigative Dermatology.

What Cortisone Cream Does to a Sunburn

Ultraviolet light damages skin cells and their DNA, and the skin responds with inflammation: redness and swelling.3PubMed Central. Inflammatory Molecules Associated with Ultraviolet Radiation-Mediated Skin Aging Damaged cells release chemical alarm signals that widen blood vessels and draw in fluid.4PubMed. Release of cytokines/chemokines and cell death in UVB-irradiated human keratinocytes, HaCaT Burned skin also makes more histamine and prostaglandins, the substances behind pain and redness, and becomes extra sensitive to them.5PubMed. Mechanisms of UV-induced inflammation

That chain of events explains why a sunburn often looks mild at the beach and angry by bedtime: the signals keep spreading for hours after you come inside. It also means the window to calm the reaction is early.

Hydrocortisone, sold as “cortisone cream,” is a corticosteroid, a medicine that copies the body’s own inflammation-calming hormone. Steroid creams can slow the redness and make it less intense.6Nature Publishing Group / Journal of Investigative Dermatology.

Steroid creams stopped working on burns stronger than about twice the dose that just turns skin pink.8Nature Publishing Group / Journal of Investigative Dermatology. The influence of corticosteroids and topical indomethacin on sunburn erythema A deep, severe burn is beyond what they can calm.

How Well It Works and Why Timing Matters

Steroid creams work better when put on within about 6 hours of the burn than later.9PubMed. Topical corticosteroids in the treatment of acute sunburn: a systematic review They also work better when kept up over time rather than used once.10PubMed. Topical corticosteroids in the treatment of acute sunburn: a systematic review Creams first used 23 hours after the burn gave no meaningful drop in redness.11PubMed. Topical corticosteroids in the treatment of acute sunburn: a randomized, double-blind clinical trial Even a medium-strength steroid at 6 hours gave no useful drop in redness.12PubMed. Topical corticosteroids in the treatment of acute sunburn: a randomized, double-blind clinical trial

If you wake up with a burn you got yesterday, a steroid cream is unlikely to change much. Using it on unbroken skin is still reasonable if it feels soothing, just with lower expectations.

The evidence for the drugstore strength is weak. In one test, a low-strength hydrocortisone cream did no better than a placebo cream for redness, pain or skin heat.13PubMed Central. Placebo controlled, crossover validation study of oral ibuprofen and topical hydrocortisone-21-acetate for a model of ultraviolet B radiation (UVR)-induced pain and inflammation Two prescription-type steroid creams, used for several days, clearly eased sunburn by days 4 to 5 compared with untreated skin.14PubMed. A randomized, controlled study of the safety and efficacy of topical corticosteroid treatments of sunburn in healthy volunteers In that study the creams caused no side effects tied to treatment.15PubMed Central. A randomized, controlled study of the safety and efficacy of topical corticosteroid treatments of sunburn in healthy volunteers Studies disagree because results depend on how strong the burn was, how strong the cream, and how soon it was used.

So expect modest help at best from the 1% tube, and more from a prescription cream your doctor gives you. Drugstore hydrocortisone is 0.5% or 1%, the mildest steroid class. Doctors can prescribe stronger creams for a severe but unblistered burn. Those are meant for short use, and not for the face without advice.

How to Use Hydrocortisone on a Sunburn

Children’s hospital guidance gives a simple routine. Put 1% hydrocortisone cream on as soon as possible; no prescription is needed.16Seattle Children’s Hospital. Sunburn Apply it 3 times a day.17Seattle Children’s Hospital. Sunburn Used early and continued for 2 days, it may reduce swelling and pain.18aspeds.com. Pediatrician Advice Until you can get some, use a moisturizing or aloe cream.19Seattle Children’s Hospital. Sunburn

Cool the skin with a shower or damp cloth, then spread a thin layer over the red skin. Rub it gently, since burned skin is tender. A thick coat adds no benefit and just holds in heat. Wash your hands afterward so the cream doesn’t reach your eyes or mouth, especially after treating a child’s face or shoulders.

Use creams only on red skin and avoid ointments.20Seattle Children’s Hospital. Sunburn Greasy ointments can block sweat glands.21aspeds.com. Pediatrician Advice

Hydrocortisone should never go on blistered skin or open sores.22SingleCare. What to do for a bad sunburn Treat around blisters and leave them intact.

The face and other thin skin absorb steroids more easily, so use sparingly there and keep it away from the eyes. Check the label for age limits before using it on young children. On a large burn, spreading steroid over a big surface increases how much is absorbed into the body, so a thin layer matters even more. If the burn covers much of your back or legs, the cream becomes impractical, and cool care and oral pain relief are likely to do more for you.

Aloe, Ibuprofen and Other Options

A nearly pure aloe vera gel reduced sunburn redness after 48 hours better than 1% hydrocortisone in a gel base.23PubMed. Investigation of the anti-inflammatory potential of Aloe vera gel (97.5%) in the ultraviolet erythema test But 1% hydrocortisone in a cream base worked better than the aloe.24PubMed. Investigation of the anti-inflammatory potential of Aloe vera gel (97.5%) in the ultraviolet erythema test One dermatology clinic calls aloe the best over-the-counter option while noting it can’t lessen a burn’s severity the way a prescription steroid can.25Epiphany Dermatology. How to Treat A Sunburn: 4 Tricks For Soothing Sunburn Relief

Choose a gel that lists aloe vera as the main ingredient and skip those with added fragrance or alcohol, which can sting burned skin. It’s a reasonable first choice if you have no hydrocortisone.

In the test that found low-strength hydrocortisone no better than placebo, oral ibuprofen did show a benefit.26PubMed Central. Placebo controlled, crossover validation study of oral ibuprofen and topical hydrocortisone-21-acetate for a model of ultraviolet B radiation (UVR)-induced pain and inflammation Taking ibuprofen early, if it’s safe for you, may help more than the cream alone. Ibuprofen blocks prostaglandins, the same pain and redness signals burned skin overproduces. Take it with food and follow the label dose. It isn’t right for everyone, including people with stomach ulcers, kidney problems or those on certain blood thinners. Acetaminophen can ease pain if ibuprofen isn’t safe for you, though it doesn’t reduce inflammation in the same way.

Cool showers or compresses ease heat. Drink extra water, since burns pull fluid to the skin. Loose clothing reduces rubbing.

Some common home fixes backfire. Butter, petroleum jelly and heavy oils trap heat. Numbing sprays with benzocaine can irritate some people. Popping blisters raises infection risk.

When a Sunburn Needs a Doctor

See a doctor for any of these:

Go for urgent care for these:

Sun poisoning is a popular name for a severe sunburn that makes the whole body feel ill, with fever, chills, nausea or headache. Those symptoms signal that the reaction has spread past the skin, which is why a cream can’t address them. A doctor can check for infection and dehydration, prescribe a stronger steroid cream or treat blisters, and advise on fluids and pain control.

Children need extra caution. They dehydrate faster, so watch their drinking and urine. Fever or listlessness after a burn warrants a call, and blistering in a baby needs prompt care.

Why Soothing a Burn Isn’t the Same as Preventing Damage

Sun exposure damages skin DNA even at doses too low to redden the skin.38PubMed Central. UV wavelength-dependent DNA damage and human non-melanoma and melanoma skin cancer So avoiding sunburn doesn’t by itself mean avoiding skin cancer risk.39PubMed Central. UV wavelength-dependent DNA damage and human non-melanoma and melanoma skin cancer Steroid creams calm redness without reducing cell damage,40Nature Publishing Group / Journal of Investigative Dermatology. The influence of corticosteroids and topical indomethacin on sunburn erythema

Sunscreen works only if you put on enough and reapply it, usually about every two hours as well as after swimming or heavy sweating. Use a broad-spectrum product. Clouds don’t block most of the ultraviolet light that burns skin, so overcast days can still burn. Seek shade at midday and wear hats and covering clothing. While a burn heals and peels, keep it out of further sun, and cover it with clothing rather than relying on sunscreen over tender skin.
