How To Treat Sunburn: Discover 6 Key Tips

Sunburn occurs after the skin is exposed to ultraviolet (UV) rays for longer than expected. This can cause redness, inflammation, and discomfort as the outer layers of the skin react to the damage.¹ Knowing how to care for sunburn effectively and what protective measures to take can help reduce pain, support your skin’s recovery, and prevent further irritation.² This article will explore what sunburn is, the common symptoms to watch for, practical ways to soothe discomfort, and the products and routines that can help your skin stay protected.

What Is Sunburn?

Understanding sunburn:
What Happens to Your Skin

Sunburn is more than just redness. It happens when ultraviolet (UV) rays penetrate the skin, damaging DNA within skin cells. In response, the body triggers inflammation, increasing blood flow to the affected area and causing redness, warmth, and tenderness.³

Sun-exposed skin can feel sensitive, tight, and uncomfortable, and peeling may occur as the skin naturally renews itself. Over time, repeated sunburn and unprotected sun exposure can contribute to visible signs of skin ageing⁴, even when redness is not immediately visible. This is why daily sun protection is so important. Wearing protective clothing, seeking shade, and applying SPF regularly can help keep your skin protected and healthy-looking. If your skin does become overexposed to the sun, cooling and caring for it gently can help soothe discomfort. After sun exposure, moisturising products can also help hydrate the skin and support its natural recovery process.

1
UV Exposure:
Spending long periods in direct sunlight, especially between 10 am and 4 pm when UV rays are strongest, can increases the likelihood of sunburn. Even on cloudy days, UV rays can penetrate and damage the skin.

2
Skin Type:
Fair or sensitive skin tends to burn more easily, as it contains less melanin, the natural pigment that helps protect against UV damage.

3
Lack of or Insufficient Sun Protection:
Skipping sunscreen, not applying it evenly, or forgetting to reapply it after swimming, sweating, or towelling can leave the skin more exposed and increase the risk of sunburn. Regular use of broad-spectrum SPF is key to reducing risk.

4
Environmental Factors:
Reflective surfaces such as water, sand, or snow can intensify UV exposure, increasing the chance of sunburn. Even shaded areas near reflective surfaces can still leave your skin at risk.⁵

Recognising Symptoms Quickly

6 sunburn symptoms
to Watch For

Recognising sunburn symptoms early can help ease discomfort and support your skin’s recovery. Noticing signs such as redness, swelling, or blisters allows you to take prompt action and prevent further irritation. ⁷

1
Redness:
Skin becomes visibly red and warm due to increased blood flow.

2
Pain:
Tenderness or sharp discomfort occurs depending on the burn severity.

3
Swelling:
Inflammation may cause puffiness and tightness.

4
Blisters:
Fluid-filled blisters protect underlying skin and should not be popped.

Peeling & Itching:
Damaged skin naturally sheds during healing, which may feel itchy. Avoid scratching to prevent further irritation or infection and soothe the skin with cooling after-sun products.

6
Flu-like Symptoms:
Severe sunburn can lead to headaches, fever, chills, or fatigue.

When to Seek Medical Advice: If you notice large blisters, severe pain, signs of infection (such as pus or unusual redness), or persistent flu-like symptoms, dizziness, or fever, seek professional care promptly.

Immediate Relief Tips

After Sunburn

Taking prompt steps can help provide sunburn relief and support your skin’s recovery. Focus on cooling, hydration, and soothing your skin to minimise irritation.

1
Get Out of the Sun:
Move indoors or into shade immediately to prevent further UV damage and protect the sunburned areas from additional exposure.

2
Cool the Skin:
Take a cool shower or bath, or gently apply damp, cold cloths for 10-15 minutes. Cooling the skin helps reduce heat and visible redness while soothing irritation.8 Avoid ice or very cold water, which can irritate sensitive skin.

- Harsh, fragranced, or alcohol-based products.
- Using ice directly on the skin.
- Popping blisters that form.⁹

How long
Does Sunburn Last?

Understanding how long sunburn may last helps you plan care and manage discomfort effectively. Healing times vary depending on severity and how promptly you look after your skin.⁶

- Mild sunburn: Typically improves within 2-3 days.

- Moderate sunburn: Redness and peeling may take 5-7 days to resolve.

- Severe sunburn: Can last longer and may require medical attention.

- Recovery factors: Healing depends on the extent of UV damage and how quickly steps such as cooling the skin or applying suitable skincare products are taken.

Steps to Protect Your Skin from Sunburn

How to help
Prevent Sunburn

Avoiding sunburn is all about protecting your skin from excessive sun exposure. Taking the right steps can help keep your skin comfortable and healthy-looking while reducing the risk of redness, irritation, and long-term damage.⁵

1. Avoid Excessive Sun Exposure

To help prevent sunburn and skin damage, avoid prolonged sun exposure, especially during peak hours when UV rays are strongest, typically between 10am-4pm. Seek shade where possible or use a parasol for added protection.

2. Wear Protective Clothing and Accessories

Hats, sunglasses, and long sleeves provide extra coverage when outdoors, especially during the hours of peak sunshine. Protective clothing reduces UV exposure to sensitive areas of the body.⁵

3. Apply Sun Cream Evenly and Regularly

Sunburn can often affect areas of the body that are easily overlooked, such as the ears, the back of the neck, elbows, knees, bikini line, back, and feet. Make sure to apply a sufficient amount of sun cream to all exposed skin and reapply regularly. For ongoing protection, it is generally recommended to reapply every two hours, or more often after swimming, sweating, or towelling off.⁵ Regular application helps keep your skin protected throughout the day.

NIVEA offers a range of broad-spectrum suncare products for full-body protection and care:

- NIVEA Protect & Moisture Lotion Sun Cream SPF50+: Offers broad UVA/UVB protection with CITRACELL-PROTECT™ (Vitamin C and Hyaluron), fast-absorbing, hydrating for up to 48 hours, non-sticky, and water-resistant.

- NIVEA Protect & Moisture Pump Spray Sun Cream SPF50+: Quick-absorbing spray for even coverage and hydration, with CITRACELL-PROTECT™ and water resistance for easy application.

4. Choose Sun Protection Suited to Your Skin’s Needs and UV Exposure Levels

Use a broad-spectrum sunscreen with a high SPF to help protect skin from UVA and UVB rays. For fair or sun-sensitive skin, a higher SPF such as SPF 50+ may provide enhanced protection, particularly during periods of increased sun exposure. Even on cloudy days, exposed skin can still be affected by UV radiation, making daily sun protection an important step in helping to reduce the risk of sun-induced skin damage and sunburn.

5. Protect Delicate Areas: Face and Lips

Areas with more sensitive skin, such as the face and lips, need dedicated care.

As the face is exposed to UV rays every day, it is advisable to apply a specialist sun protection product suitable for daily use, such as:

NIVEA UV Face Specialist Triple Protect Sun Fluid SPF50+ : Shields against UVA/UVB rays, blue light, and pollution, while keeping skin hydrated with Hyaluronic Acid.
NIVEA Sun UV Specialist Silky UV Stick Sun Cream:Targets delicate facial areas with invisible, non-greasy, water-resistant coverage.

The delicate skin on the lips also needs daily sun protection. Choose a lip care product with SPF suited to your level of sun exposure to help protect against UV-related dryness and discomfort:

NIVEA Hydro Care Lip Balm SPF15 : Keeps lips moisturised for up to 24 hours with SPF15 protection and barrier support.
NIVEA Sun Protect Lip Balm SPF50: Provides water-resistant SPF50 protection and hydration for prolonged outdoor activity.

Summary

Sunburn damages the outer layers of the skin, causing discomfort that requires gentle care. Cooling the skin with cool water, staying well hydrated, and seeking shade to prevent further exposure are important first steps in supporting recovery. After sun exposure, soothing after-sun products can help keep the skin hydrated and support its natural renewal process. Recognising early signs, caring for sensitive areas, and applying adequate sun protection regularly can help prevent sunburn and keep the skin comfortable.
