how long does sunburn last? The duration of sunburn can vary depending on its severity and how well it’s treated. Mild sunburn typically lasts for a few days to a week. During this time, you may experience redness, pain, and mild peeling. Moderate sunburn, with more intense redness and discomfort, can last up to two weeks. Severe sunburn, characterised by blistering, can take several weeks to heal completely and may even leave lasting damage. To alleviate symptoms and promote faster healing, it’s crucial to stay hydrated, apply soothing creams or aloe vera, and avoid further sun exposure. Prevention through sunscreen and protective clothing is always the best approach.
