The duration of sunburn can vary depending on its severity and individual factors. Typically, how long does sunburn last follows this timeline:

• Immediate Effects: Sunburn becomes noticeable a few hours after sun exposure. The skin turns red, becomes warm, and may start to itch or sting.
• Peak Sunburn: The most intense symptoms usually occur within 12 to 24 hours after sun exposure. At this stage, the skin may be painful and continue to itch.
• Healing Process: Over the next few days, the skin begins to heal. Peeling may start after a few days, revealing new, less damaged skin underneath.
• Full Recovery: Mild sunburn can heal in about a week, while more severe cases may take up to two weeks or longer to fully resolve.
• Long-Term Effects: It’s crucial to protect your skin from further sun damage to prevent long-term effects like premature ageing and an increased risk of skin cancer.

To alleviate discomfort and promote healing, consider using moisturisers, taking cool baths, and applying aloe vera or over-the-counter creams. However, if your sunburn is severe, blisters, or covers a large area, consult a healthcare professional.
