Certain medical treatments have been tried and studied to treat sunburn.
However, in general, most remedies have not shown any clinically proven benefit
as far as speeding the recovery or reversing the damage. Therefore most of the
treatments available are only used to treat symptoms.
Nonsteroidal anti-inflammatory drugs (NSAIDs) in oral (ibuprofen, Motrin,
Naprosyn, Advil etc.) or topical diclofenac 0.1% gel
(Solaraze) forms have shown to reduce
redness if applied before or immediately after UVB exposure. This benefit may be
diminished after 24 hours. These medications may also
help relieve the symptoms of sunburn such as pain and discomfort.
Topical steroid creams have not shown any
significant improvement in sunburn symptoms. Oral steroids such as
prednisone
have not proven to be
beneficial and have been associated with some significant side effects.
Applying Aloe Vera gel to the skin
also has not been beneficial in treating
the actual sunburn. However, this may be beneficial in treating the symptoms.
Topical anesthetics: Advertised remedies such as topical anesthetics (benzocaine) may help
with symptoms of sunburn, however, very little clinical data is available to
substantiate their effectiveness.
Sunburn is an inflammation of the skin caused by overexposure to UV
radiation from the sun.
UV radiation damages the skin and also can damage the eyes.
UV rays are most intense at noon and the hours immediately before and
after (between 10AM and 3PM).
Immediate symptoms of sunburn are hot, red, tender skin; pain when the
skin is touched or rubbed; and dehydration; several days after exposure the
skin may swell, blister, and peel.
Most sunburns are mild and can be treated with home remedies such as
applying damp cloths or compresses to reduce the pain, soaking in a tepid
bath (with no soap), gently patting the skin dry, applying soothing creams
or lotions, OTC pain relievers such as Tylenol or others, and moisturizing
the skin.
Sunburn may cause permanent skin damage and skin cancer (malignant
melanoma, basal cell carcinoma, squamous cell carcinoma).
UVB as well as UVA rays may cause damage to skin.
UV rays may bounce off water, sand, snow, and other surfaces.
Some types of skin tan after exposure to UV rays because after
repeated or prolonged exposure to UV rays the skin produces more melanin.
Persons with certain pigment disorders and individuals with fair skin
are at most risk of sunburn.
Certain diseases and conditions pose a higher risk of sunburn (for
example, albinism, lupus, porphyrias, vitiligo, and xeroderma pigmentosum).
Some medications may increase sensitivity to sunburn
(photosensitivity).
The best way to prevent sunburn is to avoid long exposure to sunlight.
Sunscreen and sun-protective clothing are important measures to limit
sun damage.
Apply sunscreen before going outdoors, apply it liberally, and
re-apply frequently.
Sun poisoning is caused by severe sunburn; its symptoms include fever,
nausea, chills, dizziness, rapid pulse, rapid breathing, dehydration, and
shock.
Sunburn is an inflammation of the skin that is caused by overexposure to
ultraviolet (UV) radiation from the sun. A similar burn can follow overexposure
to a "sun" (UV or tanning) lamp. UV radiation can also damage the eyes, although no
surface burn is apparent.
Sunburn is a very common condition. In the United States, approximately 30%
to 40% of adults and close to 80% of children and adolescents report having at
least one sunburn in the preceding year.
Can sunburn cause permanent damage?
Yes. Sunburn early in life increases the risk of developing skin cancer later
on. Repeated overexposure to ultraviolet rays can also
scar,
freckle, dry out,
and wrinkle the skin prematurely. In addition, frequent overexposure to
ultraviolet rays can increase the risk of developing eye cataracts and
macular
degeneration, a leading cause of blindness.
What is UV light?
UV light is radiation energy in the form of invisible light waves. UV light
is emitted by the sun and by tanning lamps.
The sun discharges three types of ultraviolet radiation:
ultraviolet A
(UV-A),
ultraviolet B (UV-B), and
ultraviolet C (UV-C).
Only UV-A and UV-B rays reach
earth. (UV-C does not penetrate the earth's upper atmosphere.)
Although research has long implicated UV-B as the most likely form of UV
radiation to damage the skin and cause skin cancer, it is now known that UV-A
also can be dangerous. UVB is known to affect the outer layer of skin. UVA is
much less intense than UVB, but it is about 50 times more likely than UVB to
reach deeper layers of skin to cause sun damage.
Tanning lamps also produce UV-A and/or UV-B. These artificial rays affect the
skin in the same way as do UV-A and UV-B from the sun.
When and where are UV rays most intense?
UV rays are most intense at noon and the hours immediately before and after
(between 10 a.m. and 3 p.m.), particularly in the late spring, summer, and early
autumn. Although they are less concentrated at other times of the day and year,
UV rays can still damage the skin and eyes - even in the dead of winter and on
cloudy or rainy days.
UV rays also increase in intensity in relation to altitude and latitude. The
higher the altitude, the greater is the concentration of UV rays. Likewise, the
rays are more powerful the nearer to the equator.
UV rays "bounce" off reflective surfaces - including water, sand, and snow.
Thus, a skier, swimmer, fisherman, or beachcomber may be bombarded with UV rays
from above and below.
Eczema, also known as dermatitis, is a general term for many types of skin inflammation. The most common form of eczema is atopic dermatitis. The other forms of eczema include: contact eczema, seborrheic eczema, Nummular eczema, Neurodermatitis, stasis dermatitis, and dyshidrotic eczema. Symptoms, diagnosis, and treatment of eczema may vary from person to person and may depend on the type of eczema.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. The best way to treat dehydration is to prevent it from occurring.
Skin cancer is the most common form of cancer
in humans. There are three main types of skin cancer; basal cell carcinoma and
squamous cell carcinoma (the nonmelanoma skin cancers), and melanoma.
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous
system. When only the skin is involved, the condition is called discoid lupus.
When internal organs are involved, the condition is called systemic lupus
erythematosus (SLE).
Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. The causes of vomiting differ according to age, and treatment depends upon the cause of nausea and vomiting.
Itching can be a common problem. Itches can be localized or generalized. There are many causes of itching to include: infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.
Heat rash is a skin irritation caused by excessive sweating. It can occur at any age and it appears as a rash that itches or feels prickly, and looks like a red cluster of pimples or small blisters. Pictures of heat rash are included.
Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
Melanoma is a type of skin cancer which begins in skin cells called melanocytes and affects more than 53,600 people in the United States each year. These melanocytes can grow together to form benign moles which, after a change in size, shape, or color can be a sign of melanoma. Caused by sun exposure, early detection becomes extremely important to avoid a spread to other areas of the body. Diagnosis is confirmed through a biopsy of the abnormal skin and treatment depends on the extent and characteristics of the patient.
Vitiligo is a condition in which the skin turns white due to the loss of pigment from the melanocytes, cells that produce the pigment melanin that gives the skin color.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Keratosis pilaris (KP) is a common skin disorder in which small white or red bumps appear around hair follicles on the upper arms, thighs, buttocks, and cheeks. The cause of KP is unknown. There is no cure for keratosis pilaris, and the condition may resolve on its own. Gentle exfoliation, professional manual extraction, chemical peels, and microdermabrasion, along with topical products, are the best treatments for this condition.
Heat stroke (heatstroke or sun stroke) is a form of hyperthermia. Heat stroke is a true medical emergency that can be fatal if not promptly and properly treated. Symptoms of heat stroke include: high body temperature, absence of sweating, with hot red or flushed dry skin, rapid pulse, difficulty breathing, strange behavior, hallucinations, confusion, agitation, disorientation, seizure, and coma. A victim of heat stroke must receive immediate treatment to avoid permanent organ damage.
Actinic keratoses are rough, scaly patches of skin that are considered precancerous and are due to sun exposure. Prevention is to cut sun exposure and wear sunscreen.
Burns are categorized by severity as first, second, or third degree. First degree burns are similar to a painful sunburn. The damage is more severe with second degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third degree burns. Burn treatment depends upon the location, total burn area, and intensity of the burn.
A cataract is an eye disease that causes the eye's lens to become cloudy and opaque with decreased vision. Causes of cataracts include diabetes, hypothyroidism, certain genetic illnesses, hyperparathyroidism, atopic dermatitis, and certain medications. Symptoms and signs include a decrease in vision and a whitish color to the affected eye. Treatment depends upon the patient's specific visual needs and may involve cataract surgery.
Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement fluids. Warning signs of heat exhaustion include heavy sweating, paleness, muscle cramps, tiredness, weakness, dizziness, headache, nausea or vomiting, and fainting.
Freckles are flat circular spots on the skin that may be red, yellow, tan, light brown, brown, or black in color. Lentigo is the term used to describe certain types of darker freckles. Ephelis typically appear during the sunny months. Freckles can be prevented with sunscreens, the use of wide-brimmed hats, sun-protective clothing, avoiding peak sun hours, and seeking shade and staying indoors.
Birthmarks and other abnormal skin pigmentation is caused by the body's inability to produce enough melanin. Abnormal skin pigmentation can cause conditions such as vitiligo, pigmentation loss, melasma, albinism, port wine stains, macular stains and hemangioma.
Scar formation is a natural part of the healing process after injury. The depth and size of the wound incision and the location of the injury impact the scar's characteristics, but your age, heredity and even sex or ethnicity will affect how your skin reacts.
Medical shock is a life-threatening medical condition. There are several types of medical shock, septic shock, anaphylactic shock, cardiogenic shock, hypovolemic shock, and neurogenic shock. Causes of shock include heart attack, heart failure, heavy bleeding (internal and external), infection, anaphylaxis, spinal cord injury, severe burns, chronic vomiting or diarrhea. Low blood pressure is the key sign of sock. Treatment is dependant upon the type of shock.
Moles are small skin growths that may appear flat or raised and are often tan, brown, black, reddish brown, or skin colored. They are typically about the size of a pencil eraser. There are three types of moles. Monthly skin self-exams are essential in the early detection of abnormal moles and melanomas.
Sun sensitivity (photosensitivity) is an inflammation of the skin induced by the combination of medications or substances and sunlight. The affect on the skin is redness, which looks similar to a sunburn. Generally, these reactions are either phototoxic or photoallergic. Phototoxic drugs are more common than photoallergic drugs. Symptoms of phototoxic reactions are a burning and stinging sensation and then redness. Symptoms of photoallergic reactions are itching, redness, swelling, blisters of the affected area. Treatment generally is discontinuation of the medication and topical application of creams.
Age-related macular degeneration (AMD) is a disease that gradually destroys the central vision. In people over 60, AMD is a leading cause of vision loss. Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula, leaking blood and fluid and causing rapid vision loss. In dry AMD, light-sensitive cells slowly break down in the macula, resulting in gradual vision loss. Pain is not associated with either form of AMD.
Wrinkles, whether they be fine line or deep furrows, typically appear on areas of the body that receive a high amount of exposure to the sun. Smoking, light skin type, hairstyle, the way you dress, your occupational and recreational habits, and heredity are all factors that promote wrinkling. Medical treatments for wrinkles include antioxidants, moisturizers, alpha-hydroxy acids, and vitamin A acid. Cosmetic procedures that treat wrinkles include dermabrasion, microdermabrasion, glycolic acid peels, laser resurfacing, Botox, and fillers.
Sunscreens are crucial for sun protection. Sun damage to the skin from exposure to ultraviolet rays is a risk factor for skin cancer and melanoma. To avoid sunburn, people should limit sun exposure during the peak hours of 10 a.m. to 3 p.m., wear protective clothing, and use a sunscreen. People with sensitive skin should use a sunscreen with an SPF of 30 or more.
Heat cramps usually affect people who sweat a lot during strenuous activity or work in a hot humid environment. Symptoms of heat cramps are muscle pains or spasms, usually in the abdomen, arms or legs that occur in association with strenuous activity. Heat cramps is part of a group of heat-related illnesses.
Freckles are flat, tanned circular spots that typically are the size of the head of a common nail. The spots are multiple and may develop randomly on the skin, especially after repeated exposure to sunlight. These are particularly common in people of fair complexion on upper-body skin areas like the cheeks, nose, arms, and upper shoulders. They may appear
on people as young as age 1 or 2.
Most freckles on a person's skin are usually uniform in color. On different people, freckles may vary somewhat in color -- they may be reddish, yellow, tan, light brown, brown, or black -- but they are basically slightly darker than the surrounding skin. They tend to become darker and more apparent after sun exposure and lighten in the winter months. Freckles are due to an increase in the amount of dark pigment called melanin and are not due to an increase in the total number of pigment-producing cells called melanocytes. The wor...
