Quick answer
Apply a bland fragrance-free moisturiser or pure aloe vera gel to skin that is still damp after a cool shower, and repeat through the day. Avoid benzocaine or lidocaine sprays, fragranced or alcohol-based after-sun, thick occlusives in the first hours, and any acid, scrub or retinoid. Nothing topical shortens healing — it manages comfort while the skin repairs.
Nothing goes on blistered or broken skin
What to use
| Product | What it does | How to use |
|---|---|---|
| Cool water / damp compress | Most effective comfort measure | 10–15 minutes, several times a day |
| Pure aloe vera gel | Cooling, eases tightness and itch | Aloe first on the ingredient list, no fragrance or alcohol |
| Fragrance-free emollient | Reduces water loss, improves peeling | Apply to damp skin, repeat 2–3× daily |
| Ibuprofen / paracetamol | Pain and inflammation | Standard dosing if suitable for you |
| 1% hydrocortisone | Short-term itch on small unbroken areas | Few days only; pharmacist advice first |
| Extra fluids | Replaces fluid pulled to the skin | Increase intake for 48 hours |
What to avoid
- Benzocaine / lidocaine sprays — common cause of allergic contact dermatitis.
- Fragranced or alcohol-based after-sun — sting and dry the barrier.
- Petroleum jelly and heavy oils early — trap heat in the first hours.
- Ice directly on skin — cold injury over heat injury.
- Butter, yoghurt, vinegar, toothpaste — no evidence, real infection risk.
- Acids, retinoids, scrubs, exfoliating mitts — strip fragile healing skin.
- Sunscreen on broken skin — cover with clothing instead.
Match the product to the phase
- Hours 0–24 (hot, red): cooling and fluids do most of the work; light aloe if it feels good.
- Day 2–3 (tight, itchy): bland emollient several times a day; antihistamine at night if itch disturbs sleep.
- Day 4–7 (peeling): keep moisturising, do not pull the skin, and keep the area out of the sun.
- Week 2+ (new skin): protect with clothing; the fresh skin burns far more easily.

Frequently Asked Questions
A bland, fragrance-free moisturiser or pure aloe vera gel applied to skin that is still damp after a cool shower. That combination addresses the two things topical products can actually help with: water loss from the barrier, and the tightness and itch that come with it.
Both are reasonable. Aloe feels cooler and is pleasant in the first day or two; a fragrance-free emollient is better for the dry, tight, peeling phase from about day three. What matters more than the choice is that the product has no fragrance, alcohol or anaesthetic in it.
Not in the first 24 hours. Heavy oils and occlusives trap heat in freshly burned skin. Once the heat has settled and the skin is only dry and tight, a plain oil or emollient is unlikely to cause harm, but a purpose-made fragrance-free moisturiser is a better choice.
Avoid petroleum jelly while the skin is still hot — it seals heat in. It also should not go on blistered or broken skin. Later in healing, a thin layer on dry unbroken areas is acceptable, though a lighter emollient is usually more comfortable.
A 1% hydrocortisone cream is sometimes used briefly on small, very itchy areas of unbroken sunburned skin. Do not use it on blisters, broken skin, large areas, or on children's faces, and do not continue beyond a few days without advice from a pharmacist or doctor.
They provide brief numbing but are a well-recognised cause of allergic contact dermatitis, which turns a burn into a burn plus a rash. Dermatology guidance generally advises against them; oral pain relief is safer and more effective.
No. None of these have credible evidence, vinegar is an acid on already-damaged skin, and food products on broken skin introduce infection risk. Cool water, bland moisturiser and oral pain relief outperform all of them.
Not on broken or blistered skin. On intact healing skin, sunscreen is better than nothing but clothing and shade are the right approach until redness and tenderness have fully resolved.
Cool compresses, generous bland moisturiser, loose cotton clothing, and an oral antihistamine at night if itch is disturbing sleep and it is suitable for you. Scratching or exfoliating peeling skin makes the itch and the redness last longer.
Get medical advice if the burn blisters extensively, becomes more painful after day 2–3, develops spreading redness, warmth or pus, or if you develop fever, vomiting, confusion or dehydration.
