Get out of the sun, cool the skin gently and assess how you feel. Sunburn is skin damage from ultraviolet exposure. A cosmetic oil or an aftersun product cannot undo that exposure, and a more painful burn is not a reason to increase the concentration of an essential oil or CBD product.
This updated edition keeps the original article’s aim—helping you respond to sunburn—but replaces its homemade aloe, calendula, essential-oil and CBD burn-treatment suggestions with current public-health guidance. It is general information, not a diagnosis of the depth of a burn.
1. Cool the skin gently
Use a cool shower, bath or damp towel. Do not put ice or ice packs directly on sunburnt skin. Ameli recommends running tap water around 15–25°C over the affected area for about 15 minutes; take care not to chill a child. Stop further sun exposure immediately. See Ameli’s advice (in French).
2. Drink water and watch for other symptoms
Drink water regularly. A fixed “two litres minimum” is not a universal instruction for every age or medical situation. Watch for dizziness, vomiting, marked weakness or other signs that you are unwell rather than treating the skin alone. Ask a pharmacist or clinician if you need advice about pain relief; follow any medicine’s leaflet and suitability restrictions.
3. Choose a simple, suitable moisturiser
For a mild sunburn on intact skin, the NHS suggests an aftersun product or an unperfumed moisturiser. Ask a pharmacist which product is appropriate if you are unsure. Do not use petroleum jelly on sunburnt skin. Stop any product that stings or worsens irritation.
The earlier article recommended cutting a fresh aloe leaf and applying its contents. That home preparation is not included in this update: the identity, cleanliness and composition of a leaf preparation are not equivalent to a formulated product. A high aloe percentage or an organic logo does not establish suitability for a burn.
4. Keep essential oils and improvised blends off the burn
Do not add lavandin, another essential oil, CBD drops or a homemade calendula-and-aloe mixture to a sunburn treatment. The original article linked Atelier Populaire cosmetic oils to claims about inflammation, pain and skin regeneration. Those product-treatment claims are not retained here, and the suggestion of stronger CBD for a more severe burn has been removed.
Cosmetic face, body and hair oils have their own labelled uses. They are not presented here as medicines for damaged or blistered skin. If the burn is significant, seek medical advice rather than choosing a stronger cosmetic concentration.
5. Protect the skin while it heals
Wear loose clothing that does not rub the affected area. Keep burned skin out of direct sunlight until healed. Do not burst blisters, scratch peeling skin or pull it away. An aftersun product is not a sunscreen, and sunscreen is not permission to expose a healing burn again. The NHS sunburn guidance gives these practical precautions.
6. Know when to get medical help
The Health Canada first-aid guidance also highlights severe pain, blistering and illness. Seek urgent medical advice for blistering or swollen skin, a high temperature, shivering, headache, dizziness, nausea or muscle cramps after sun exposure. A baby or young child with sunburn also needs medical advice. These are reasons to assess the whole person, not just the visible redness.
Ameli also advises consultation for extensive burns, burns on fragile areas such as the face or hands, increasing redness or pus, eye pain or light sensitivity, confusion and signs of dehydration. Contact emergency services for severe illness, collapse or confusion. If you are unsure how serious the burn is, a healthcare professional can assess it. See when to consult (in French).
Reduce the risk next time
Use shade, covering clothes, a hat and UV-protective sunglasses, and check the local UV index. On exposed, uninjured skin, choose sunscreen with UVA and UVB protection and SPF 30 or higher; apply and reapply as directed, including after swimming or heavy sweating. Sunscreen complements clothing and shade; it does not make prolonged exposure safe.
Keep babies out of direct sunlight. Avoid assuming that a particular hour, a cloudy sky or a mineral filter guarantees protection. The old claims that a sunscreen offers “optimal” protection for everyone or is automatically harmless to marine ecosystems are not repeated. Product age limits, precautions and instructions must be checked on the actual label. See Ameli’s sun-protection guidance (in French).
