Does aloe vera help a sunburn?
It soothes, and that is worth something: cool aloe gel on unbroken skin relieves heat safely. Evidence that it heals a burn faster is weak; shade, cooling, moisturizer, fluids and a painkiller matter more.

Quick answer
The bottom line
Aloe vera gel is a reasonable thing to put on a sunburn, as long as the skin is not broken and the product is mostly aloe rather than alcohol and fragrance. Kept in the fridge it cools, it adds moisture, and it does no harm. What it does not do, on the evidence, is heal the burn faster: a review of burn studies found weak, mixed results, and a Cochrane review found too little evidence to judge. Treat a sunburn as the injury it is: out of the sun, cool showers or compresses, a plain moisturizer, plenty of water, and ibuprofen or paracetamol for the pain. Blisters over a large area, fever, chills or confusion need medical care.

Three things worth remembering
Section 01
A sunburn is a radiation injury, not dryness
Sunburn is skin damaged by ultraviolet radiation: cells are injured, inflammation follows within hours, and the redness, heat, pain and later peeling are the skin clearing damaged cells and repairing itself. Nothing applied to the surface undoes the injury; the aim of treatment is comfort, moisture and avoiding a second dose while the skin heals over a week or so.[4][3]
Every sunburn also adds to lifetime skin-cancer risk, which is why guidance treats a burn as a reason to look at sun habits rather than a one-off to be soothed and forgotten.[4]
Section 02
What aloe gel does, and what the studies found
Aloe gel is mostly water with plant sugars and small amounts of other compounds. On skin it cools by evaporation, adds a thin layer of moisture and feels calming, which is why the American Academy of Dermatology lists it as an optional soothing step. Those effects are immediate and do not need a trial to confirm.[3]
Whether aloe makes burns heal faster has been studied, mostly on burns from heat rather than sun. A systematic review of those trials found some shorter healing times but rated the studies small, inconsistent and low quality; a Cochrane review of aloe for wounds concluded there was not enough evidence to say it helps. That is the honest position: soothing, yes; healing, unproven.[1][2]
Section 03
How to use it, and what to avoid
Choose a gel that is mostly aloe, without alcohol, fragrance or menthol, which sting and dry burned skin, and without a topical anaesthetic ending in “-caine”, which dermatology guidance warns can irritate or cause allergy. Keep it in the fridge and apply a thin layer to cool, unbroken skin as often as it feels good. Gel from a cut leaf is fine on intact skin but can be messy and occasionally irritates.[3][4]
Do not put aloe, or any product, on open blisters; leave blisters intact and cover large ones loosely. Petroleum jelly and heavy oils trap heat in the first day and are better left until the burn has cooled. If a burn is peeling, a plain fragrance-free moisturizer does the same work as aloe.[3][4]
Section 04
What actually helps a sunburn, in order
Get out of the sun and stay out until the burn has healed. Cool the skin with a cool shower, bath or damp compresses, then pat dry and apply a moisturizer while the skin is damp. Drink extra water, because a burn draws fluid to the skin. Take ibuprofen or paracetamol for pain and to reduce swelling, following the label. Wear loose clothing over the burn.[3][4]
Seek medical care for blistering over a large area, a burn on a baby or young child, severe pain, swelling, fever, chills, headache, nausea or confusion, which can mean heat illness or a burn severe enough to need treatment.[4][3]
