The Long-Term Effects of Sunburn: Skin Damage and Cancer Risks

Sunburn is a serious skin reaction resulting from too much contact with ultraviolet (UV) radiation from the sun. The immediate effects include red, painful skin, which can overshadow the more serious long-term damage occurring beneath. Each sunburn adds to the overall harm to the skin, increasing the chances of premature ageing and skin cancer.

This article talks about what sunburn is, what causes it, how to recognise the symptoms, and more.

What Is Sunburn? 

Sunburn happens when ultraviolet (UV) radiation harms the skin by damaging the DNA in the skin cells. This damage causes the body to react with inflammation, resulting in increased blood flow in the affected areas, which results in redness, warmth, and discomfort.

Although the surface inflammation usually fades within a week, the damage goes deeper into the skin, causing lasting changes even after the visible signs are gone. The effects of sunburn on the skin result in permanent changes at the cellular level.

What are the causes of sunburn?

The cause of sunburn skin is overexposure to ultraviolet radiation. This radiation primarily comes from sunlight but can also originate from artificial sources such as tanning beds. There are three types of UV radiation:

1. UVA Rays: These reach the deeper layer of the skin, harming collagen and elastin, two critical skin components.
2. UVB Rays: These mainly impact the outer skin layer and are the major cause of sunburn.
3. UVC Rays: These are mostly blocked by the atmosphere before they reach the Earth.

Several environmental factors increase the risk of UV exposure, including midday sun (from 10 AM to 4 PM), being close to the equator, higher altitudes, and reflective surfaces like water, sand, or snow. Sunburn on the face occurs frequently due to continuous exposure during everyday outdoor activities, often with insufficient protection.

What Are the Symptoms of Sunburn?

Sunburn symptoms usually appear 1 to 4 hours after exposure and become more intense over the next 24 to 36 hours. The main signs include:

1. Redness and inflammation
2. Warmth in the affected areas
3. Pain when touched
4. Swelling in some areas
5. Fluid-filled blisters in severe cases

Sunburn on the face usually appears in specific areas, such as the cheeks, nose, forehead, and chin. In more serious cases, sunburn symptoms can progress to include intense pain, blistering, and peeling as damaged skin cells shed during the healing process.

What Are the Risk Factors of Sunburn?

The factors that increase sunburn risk include:

1. Fair Complexion: Limited melanin production increases vulnerability.
2. Geographical Residence: Living near the equator or at high elevations raises UV exposure.
3. Previous History: Past sunburns increase future risk.
4. Photosensitizing Medications: Some antibiotics and retinoids increase sensitivity.
5. Inadequate Protection: Not using sunscreen or protective clothing increases the risk of sunburn.

Repeated episodes of sunburn increase the risk of developing various sunburn-related skin conditions later in life.

Medical professionals classify types of sunburn into three categories:

1. First-degree Sunburn: It affects the top layer of skin.
2. Second-degree Sunburn: It reaches into the second layer and can cause blistering.
3. Third-degree Sunburn: It involves severe damage that requires medical attention.

Understanding the types of sunburn is essential for prevention and treatment.

How to Diagnose Sunburn?

Medical professionals diagnose sunburn through several methods:

1. Visual Examination: Assessing the skin’s appearance and noting the distribution and severity of redness.
2. Patient History Review: Discussing recent sun exposure patterns to understand risk factors.
3. Symptom Assessment: Evaluating the severity of symptoms to categorize the sunburn appropriately.

For sun burn on face, doctors focus on the patterns on the exposed areas, like the nose and cheeks. While most cases present obvious clinical features, healthcare providers can also differentiate sunburn from other conditions, such as allergic reactions or skin infections.

The long-term effects of sunburn on the face include faster skin aging, weakened skin immune function, and a higher risk of skin cancer. Sunburn treatment mainly focuses on managing symptoms rather than repairing underlying cellular damage.

FAQs

1. How to treat sunburn on face fast?

To treat sunburn on the face, use a cool compress, apply aloe vera gel, hydrate, and consider pain relievers if needed.
