Sunburn is caused by the skin's reaction to ultraviolet light exposure. It appears as reddening and tenderness of the skin and usually occurs between 12 and 24 hours after the exposure. It can develop blisters and shedding of the outer layer of skin.
Sunburn is caused by the skin's reaction to ultraviolet light exposure. It appears as reddening and tenderness of the skin and usually occurs between 12 and 24 hours after the exposure. It can develop blisters and shedding of the outer layer of skin. Some oral medications used for other medical conditions, most commonly hydrochlorothiazide (a blood pressure medication) may make the skin more sensitive to sunburning.First Aid GuideIf you have suffered a sunburn:Further direct sun exposure should be avoided for a few days. Cool water or cool milk soaks may help cool and soothe the affected areas. Acetaminophen and ibuprofen can help decrease the redness and pain. Applying a greasy cream or ointment may actually make the pain worse by trapping the heat on the skin. Drink a lot of fluids.Do not attempt to break any blisters that may form; you can cover these with gauze if necessary. If any break on their own, a topical antibiotic ointment can be applied. A moisturizer can help with skin peeling afterward. Avoid topical products that end in "-caine" as they can sometimes further irritate the skin.Prevention is very important. To reduce risk of skin cancer later in life, sunburns should be prevented.Avoid direct sun in the middle of the day (10 AM to 3 PM). Remember: snow and water reflect light to the skin, and clouds still let a lot of light through, so you may still be exposed to ultraviolet light even on cloudy days. Use a hat with a wide brim. A baseball hat does not give much protection. Cover up with tightly woven clothing. Some manufacturers make specialty clothing with a high sun protection factor (SPF) rating, or you can purchase a special ingredient to be added to your washer that can "wash" SPF into your clothing. Use sunscreen on all exposed skin areas, including the lips, before going outdoors. A broad spectrum (blocks UVB and UVA light), with an SPF of at least 30, is best. Apply generously 30 minutes before going outdoors, and reapply every 2 hours or after swimming or sweating a lot. Do not use tanning beds!
A solar lentigo (plural, solar lentigines), also known as a sun-induced freckle or senile lentigo, is a dark (hyperpigmented) lesion caused by natural or artificial ultraviolet (UV) light. Solar lentigines may be single or multiple. This type of lentigo is different from a simple lentigo (lentigo simplex) because it is caused by exposure to UV light. Solar lentigines are benign, but they do indicate excessive sun exposure, a risk factor for the development of skin cancer.
Chickenpox (varicella) is an infectious disease caused by the varicella-zoster virus that goes away on its own. Infection spreads among humans through fluids from the airways, such as from coughing and sneezing, with non-infected household members at high risk of becoming infected as well. The development (incubation) period is 14–16 days, and the first sign of disease is a rash. People are considered contagious for 2–5 days before the onset of skin lesions and for 6 days after the last series of rashes have appeared.The most common complication is infection of lesions with bacteria. Rare complications include lung infection (pneumonia) or brain infection (encephalitis). Children who have weak immune systems, eczema, or recent sunburns have more severe symptoms. Because the virus remains resting (latent) in the parts of nerves that are near the spinal cord (nerve roots) for life, about 1 in 10 adults will get shingles (zoster) when the virus reappears, usually under conditions of stress to the body.After having chickenpox, a person is usually immune for life, although reinfection is possible.
Milia are common, normal skin findings that look like tiny white bumps, usually on the face. They can occur in people of all ages but are most common in newborn babies, where they appear on and around the nose. In teens and adults, they are commonly found on the cheeks and around the eyes. Milia are formed when the top layer of skin does not shed normally but instead becomes trapped in a tiny pocket on the surface of the skin. This is similar to how some acne forms, but milia are not inflamed like acne, and treating milia with acne therapies will only irritate the skin. Your doctor can help you differentiate between acne and milia and can recommend proper treatment.
Actinic keratoses, also known as solar keratoses, are small rough or scaly areas of skin due to damage from sun exposure. Some actinic keratoses can turn into squamous cell skin cancer, so it is important to perform self-examinations often and catch them early.
Scarlet fever is a contagious infection of the upper respiratory tract (mostly the throat) that characteristically has a red, sandpaper-like rash. The infection is caused by a poison (toxin) produced by a bacterium called group A streptococcus. The rash appears 1–2 days after onset of symptoms (ie, sore throat and fever) and starts on the neck and spreads downward on the body. The rash generally covers all of the skin on the body with the exception of the face. Applying pressure to the rash will cause the skin to turn white. After 3–4 days, the rash begins to fade, and sometimes the skin peels when the rash disappears, similar to sunburn.
Cellulitis is the medical term for inflammation and infection of the skin. It is often caused by the bacteria Streptococcus or Staphylococcus (commonly known as strep and staph, respectively), which usually live on the skin of healthy people but when the skin is damaged (by a cut, scratch, or bug bite, for example), it can overgrow and cause cellulitis. Cellulitis causes the skin to look reddened, similar to a sunburn, and to be warm, tender, and swollen. The redness may spread quickly over the course of hours. The person may experience fevers or chills or feel ill. If left untreated, cellulitis can cause bacteria to enter the blood stream, which is potentially life threatening.
Sunscreens are an important part of skin care. These products reduce the risk of skin cancers, protect from photoaging caused by the sun, and prevent sunburns.
With summer just around the corner, it's important for everyone to know a little bit more about sunburns. What are they? What can you do to avoid them? And what can you do once you have a sunburn?
The summer is a great time to enjoy the sun and get some extra Vitamin D but it’s also a time when we sunburn the most. Not only can we get sunburn from a being outside on a sunny or cloudy day but we can also get burned from tanning salons. It’s the UV light from the sun and the tanning beds that gives us the tan and the burn. So what can we do about it?
Researchers at King's College London have found a molecule in the body which is the cause of the pain felt from a sunburn. The discovery could lead to medications to treat pain caused by other common inflammatory conditions such as arthritis, according to the study.
We all know that it is best to avoid sunburns by using sunscreens and staying out of the sun during peak hours – important considerations for long-term skin health and skin-cancer prevention. But sometimes things happen. A forgotten hat, thinking you’re protected from the sun’s rays under your beach umbrella, neglecting to reapply sunscreen after a swim – everyday experiences like these can lead to a nasty sunburn and the pain that comes along with the characteristically red skin.
Nearly everyone has experienced some type of sunburn, and even a mild burn can cause significant discomfort with pain, itching, burning, dry and peeling skin, and, in severe cases, blistering. The best way to treat a sunburn is to prevent one.
There has been extensive media coverage of recent studies linking vitamin D deficiencies to many common conditions and diseases, including cancer, osteoporosis, elevated blood pressure, infection, and cardiovascular and autoimmune disorders. The principal source of the vitamin is unprotected exposure of the skin to the sun’s UVB rays – the kind that also cause sunburn, premature aging of the skin, and skin cancer.
With summer well under way, whether you’re a routine sunscreen user or were driven to the drugstore by a bad sunburn, you’ve probably been overwhelmed by the enormous selection of sunscreen products on the shelves. In addition, the Food and Drug Administration (FDA) released new guidelines and regulations last month regarding sunscreen labeling that will be implemented before the next summer, so even if you are sticking to a familiar product, there’s room for confusion, as the packaging and labels may change to fit regulations. Here is a primer to help you navigate the products and choose which is best for you.
