What is sunburn?

Sunburn is a skin burn caused by excessive exposure to the sun's ultraviolet (UV) rays. These rays damage skin cells, causing redness, pain and sometimes blistering. Symptoms generally appear a few hours after exposure, and can last several days.

How can I prevent sunburn?

Preventing sunburn involves a number of essential measures:

• Regular application of sun cream with a high sun protection factor (SPF), even on cloudy days.
• Wear protective clothing, such as wide-brimmed hats and sunglasses with UV protection.
• Limit sun exposure between 10 a.m. and 4 p.m., when UV rays are most intense.
• Seek shade whenever possible.
• Reapply sunscreen every two hours and after swimming or sweating.

What to do in the event of sunburn?

In the event of sunburn, follow these steps to relieve pain and speed healing:

• Cool the skin with cold water or damp compresses for 10 to 15 minutes.
• Apply a lotion or gel containing aloe or calamine to soothe inflammation.
• Drink plenty of water to prevent dehydration.
• Avoid exposing burned skin to other sources of heat, including the sun.
• Take painkillers such as ibuprofen or paracetamol to reduce pain and inflammation.

What are the symptoms of severe sunburn?

Severe sunburn can present the following symptoms:

• Intense redness and increased pain.
• Fluid-filled blisters that may burst.

• Headaches and dizziness.
• If you experience any of these symptoms, consult a healthcare professional immediately.

What are the risks associated with frequent sunburn?

Frequent sunburn considerably increases the risk of skin cancer, including melanoma, the most dangerous form. They also accelerate skin aging, causing wrinkles and loss of firmness. What's more, repeated exposure to UV rays without protection can weaken the skin's immune system.

How to choose an effective sun cream?

• A sun protection factor (SPF) of 30 or more.
• Broad-spectrum protection against UVA and UVB rays.
• A water-resistant formula if you plan to swim or perspire.
• Hypoallergenic ingredients for sensitive skin.
• Apply sunscreen generously 30 minutes before exposure and reapply every two hours.

What natural remedies can help treat sunburn?

Natural remedies to relieve sunburn include:

• Aloe vera gel: Apply directly to the skin for its anti-inflammatory and moisturizing properties.
• Cold milk compress: Relieves pain and inflammation thanks to the proteins and fats in milk.
• Oatmeal bath: Helps reduce itching and soothe irritated skin.
• Honey: Accelerates healing thanks to its antibacterial and moisturizing properties.

Can sunburn cause long-term skin damage?

Yes, sunburn can cause long-term skin damage. Effects include:

• Premature aging of the skin, such as wrinkles and age spots.
• Increased risk of skin cancer, including melanoma.
• Skin fragility and reduced ability to regenerate after injury.

What are the medical treatments for severe sunburn?

For severe sunburn, medical treatments may include:

• Corticosteroid creams to reduce inflammation.
• Antibiotics for infected blisters.
• Specialized care for severe burns, sometimes involving sterile dressings and pain relief.

How long does a sunburn typically last, and how can I tell if the skin is healing?

A sunburn usually lasts between 3 and 7 days, depending on the severity of the burn. Symptoms such as redness and pain gradually diminish, while the skin may begin to peel at the end of the healing phase. Signs that the skin is healing include reduced inflammation and improved skin color. If the skin remains red and painful beyond this point, or if blisters appear, it is advisable to consult a doctor.

How important is internal and external moisturizing after sunburn?

Internal and external hydration is crucial to healing after sunburn. Drinking plenty of water helps prevent dehydration, which can worsen symptoms. Using moisturizing creams rich in aloe vera or natural oils helps restore lost moisture and protect the skin barrier. Applying these creams regularly and drinking fluids help reduce desquamation and speed up skin recovery.
