Sunburn is a type of burn caused by ultraviolet B radiation from the sun. The skin becomes red and swollen, causing it to expand. As the swelling starts to go down, the outer layer of skin, made of dead skin cells, doesn't shrink along with the healthy skin underneath, resulting in peeling. This process is the body's way of ridding itself of damaged cells and is a sign of damage and a step in the right direction.

What You'll Learn
Sunburn is caused by UV light, which damages skin cells
Sunburn is a type of radiation burn that affects the skin. It is caused by overexposure to ultraviolet (UV) light, usually from the sun, but it may also be caused by artificial sources such as tanning lamps, welding arcs, or ultraviolet germicidal irradiation. UV light damages skin cells by targeting the DNA within them. This damage can lead to mutations that cause the cells to misunderstand their function, resulting in uncontrolled cell growth and the formation of tumors, which may become cancerous.
The extent of a sunburn depends on skin type, with people of lighter skin tones being at a higher risk of serious sunburn, as well as the amount of UV exposure. Sunburn typically presents as red or reddish skin that is hot to the touch, painful, and swollen, and may be accompanied by general fatigue, mild dizziness, blistering, peeling skin, itching, and nausea.
The skin's blood vessels dilate in response to sunburn, leading to redness, inflammation, and swelling. The body then sends immune cells to attempt to repair the damage. Some skin cells can be repaired, while others die off. If the DNA is too damaged, cell death is triggered, and the tissue is replaced.
Sunburned skin often begins to peel as the body attempts to rid itself of damaged cells. This peeling is a sign of damage but also indicates that the body is healing and regenerating new skin. While it may be tempting to pick at peeling skin, it is important to allow it to slough off on its own to avoid further damage and potential scarring.
To soothe sunburned skin and promote healing, it is recommended to use bland, fragrance-free, hypoallergenic moisturisers, and aloe vera gel. Topical hydrocortisone creams or ointments can also help reduce inflammation and relieve discomfort. It is crucial to protect the skin from further sun exposure during the healing process by seeking shade, wearing protective clothing, and using sunscreen with an SPF of at least 30.

Peeling is a sign of healing and a way to remove damaged cells
Sunburns are caused by exposure to ultraviolet B radiation from the sun. The extent of a sunburn depends on your skin type and the amount of UV ray exposure. The skin turns red and swells up, and after about three days, the swelling starts to go down. This is when the peeling usually begins.
Peeling is a sign of healing and a way for your body to remove damaged cells. The skin becomes red and swollen, causing it to expand. As the swelling subsides, the outer layer of skin, made of dead skin cells, doesn't shrink with the healthy skin underneath, leading to peeling. This process helps your body get rid of dead, damaged skin cells exposed to the sun's harmful UV rays. The damage to these cells can include DNA mutations, which could eventually lead to skin cancer. Therefore, it is crucial to allow the peeling process to occur naturally and not forcibly remove the peeling skin.
To aid the healing process, it is recommended to moisturize the affected area with aloe vera or soy-based products. Moisturizing helps soothe sunburned skin and restore the skin barrier. It is also important to drink plenty of water to prevent dehydration. Additionally, it is imperative to practice sun protection while the peeling burn is healing. This includes wearing protective clothing, seeking shade, and avoiding peak sun hours (10 am to 4 pm).
While peeling is a natural healing process, sunburns can increase the risk of scarring and cause premature signs of aging. To minimize these risks, it is essential to prevent sunburns by using sunscreen with an SPF of at least 30 and reapplying it regularly.

Avoid peeling skin off as it may expose new cells to infection
Sunburns are caused by exposure to ultraviolet B radiation from the sun. When the body's defences are overwhelmed by too much exposure to UV light, a toxic reaction occurs, resulting in a sunburn. The extent of a sunburn depends on skin type and the amount of UV exposure. People with lighter skin are at a higher risk of experiencing a serious sunburn.
Sunburns are unsightly and dangerous, increasing the risk of developing skin cancer. When the skin begins to peel, it is a sign that the body is trying to rid itself of damaged cells. The epidermis, or outermost layer of skin, plays a crucial role in protecting the body against bacteria and germs, even though it is thin.
While it may be tempting to peel off the dead skin, doing so can expose new cells to infection. Picking at or pulling off peeling skin can create an opening that lets in bacteria, increasing the risk of infection. Instead, allow the skin to slough off naturally. This is part of the skin's natural healing process.
To aid in the healing process, it is recommended to moisturise the area with an aloe vera- or soy-based product. Moisturising helps soothe sunburned skin, but it is important to avoid petroleum-based or other oil-based creams, as they may trap heat and exacerbate the burn. Additionally, drinking extra water can help prevent dehydration.
To prevent sunburns and the subsequent peeling, it is crucial to practice effective sun protection. This includes wearing protective clothing that covers the skin when outdoors, seeking shade, and avoiding peak sun hours (10 am to 4 pm). Choosing a sunscreen with an SPF of at least 30 and applying it 20 minutes before sun exposure can also help.

Moisturising helps restore the skin barrier and curb peeling
Sunburns are caused by overexposure to ultraviolet B radiation from the sun. This radiation overwhelms the body's defences, leading to a toxic reaction in the skin. The extent of sunburn depends on skin type and the amount of UV exposure. Lighter-skinned people are at a higher risk of serious sunburn.
Sunburned skin starts peeling when the body tries to rid itself of damaged cells. This usually starts about three days after sustaining the burn. The peeling is a sign that the skin is healing, but it can also increase the chances of scarring.
Moisturising the skin with an aloe vera or soy-based product can help restore the skin barrier and curb peeling. Moisturising keeps the skin hydrated, allowing it to heal faster. It also softens the dead skin, reducing the temptation to pick at it. However, it is important to avoid petroleum-based or oil-based creams, as these can trap heat and make the sunburn worse. Instead, opt for a thick cream or ointment to seal in moisture, and choose a fragrance-free product to avoid skin irritation.
Other ways to manage sunburn and peeling include:
- Using anti-inflammatory medications, such as aspirin, ibuprofen, or naproxen, to reduce pain and inflammation.
- Applying a thin layer of over-the-counter 1% hydrocortisone cream to soothe the skin and reduce inflammation, itching, and irritation.
- Protecting the skin by wearing protective clothing that covers the skin when outdoors and avoiding peak sun hours (10 am to 4 pm).
- Staying out of direct sunlight until the skin has healed to avoid further UV damage.
- Keeping the skin hydrated by drinking extra water to prevent dehydration.

Prevent sunburn with sunscreen, clothing, and shade
Sunburn is a type of burn caused by ultraviolet B radiation from the sun. Spending too much time in the sun without protection can lead to skin damage and an increased risk of skin cancer. To prevent sunburn, it is important to take precautions such as seeking shade, wearing sun-protective clothing, and applying sunscreen.
When outdoors, it is essential to seek shade, especially during peak sun hours, typically from 10 am to 4 pm. Finding shade under a tree, an umbrella, or a canopy can help protect your skin from direct sunlight. Additionally, wearing sun-protective clothing is crucial. Look for dense fabrics with a tight weave, such as lightweight and long-sleeved shirts and pants. Dark or bright colors offer more protection than light colors. For example, a long-sleeved denim shirt provides an SPF of about 1,700, while a white T-shirt offers an SPF of around 7. Don't forget to cover your feet with shoes or sandals that provide sun protection.
Applying sunscreen is another vital step in preventing sunburn. Choose a sunscreen with an SPF of at least 30 and apply it generously to all areas of the skin not covered by clothing, including the face, ears, feet, and backs of hands. Apply sunscreen 20 minutes before sun exposure and reapply regularly, especially after swimming or sweating. Remember, sunscreen alone is not enough; it should be used in combination with shade and clothing for effective sun protection.
By following these simple steps—seeking shade, wearing protective clothing, and applying sunscreen—you can effectively prevent sunburn and reduce your risk of skin damage and skin cancer. Taking these precautions will help you enjoy the sun safely and maintain healthy skin.
