How long does emollient therapy take to work for sunburn?

Sunburn is an inflammatory skin injury caused by ultraviolet exposure. An emollient reduces water loss and friction, so it may make tightness or flaking feel better without undoing the injury. Apply it only to intact skin that feels dry; a thick, greasy layer over hot skin may feel uncomfortable. Peeling is part of the skin’s recovery and should not be pulled away. Further sun exposure can prolong irritation and deepen colour changes.

Cool the skin with a cool, damp cloth or a lukewarm shower, then pat dry and apply a gentle fragrance-free moisturiser while the skin is slightly damp. Drink fluids, wear loose clothing, and stay out of direct sun until healed. Do not use ice directly, pop blisters, or apply numbing products that irritate the skin. Read [Sunburn] and [Emollient Therapy] for related guidance.

Seek urgent medical care for extensive blistering, severe swelling, confusion, faintness, repeated vomiting, or signs of dehydration. Get advice if a child or older adult has a significant burn, if the eyes are affected, or if pain and redness are worsening rather than easing. Pus, spreading warmth, or fever can indicate infection and should be assessed.

Ask which moisturiser is suitable for the affected area, whether you need pain relief, and how to protect the skin during recovery. Ask how to care for blisters and which symptoms mean the burn needs an examination.
