Poison Ivy, also known as rhus dermatitis, is caused from an allergic reaction to the oil resin, urushiol, found in the leaves, stems and roots of poison ivy, poison oak, and poison sumac. It is very common in the summer months.
Cellulite is not a medical condition. It describes that lumpy dimpled flesh usually found on the upper thighs and buttocks that often make people feel self-conscious about wearing shorts or a bathing suit. Cellulite is a result of fat pushing against connective tissue causing the surface of the skin to pucker.
Did you ever wonder why the tips of the fingers wrinkle like a prune when exposed to water for a long period of time? People often think that osmosis causes water to enter the outer layer of skin making the fingertips swell. But since the 1930's, scientists have known that fingertips don't swell or wrinkle when there is nerve damage to the fingers, even with prolonged submersion in water.
Many people have them, those dark circles under the eyes. They make the face look tired and older. They affect our self-esteem. Dark under eye circles can be seen with any skin type but are definitely more common in individuals with darker complexions.
Acne is a chronic condition caused when hair follicles become plugged with dead skin cells and oil (secreted from an attached sebaceous gland.) Although acne most commonly appears in puberty, it can be experienced in adults, as well. Acne typically appears on the face, chest, back, and shoulders, the areas with the largest number of oil glands. Acne can take several forms.
Mycotic Conditions are those caused by yeast and fungus. A lipid dependent yeast that is normally found on the scalp, called Malessezia, feeds on the lipids from sweat glands and likely plays a role in dandruff and seborrheic dermatitis.
Millions of Americans will take to the outdoors this winter. The health benefits of winter sports are numerous. The release of endorphins elevate mood and help ward off "cabin fever." Engaging in winter sports burns more calories than equivalent warm weather activites as it takes more energy for the body to maintain its body temperature in colder environments. But exposure to cold temperature, wind and wet weather may lead to freezing of the skin and underlying tissues, a condition called "frostbite."
Cracked heels, also known as heel fissures, are experienced by over 20% of US adults over age 21. More common in women than men, this condition is often nothing more than a cosmetic nuisance. Deep "heel fissures" however, can develop and be quite painful. In rare cases, heel fissures may lead to infection.
Spider veins are those small weblike networks of red, purple and blue vessels that are easily visible through the skin and found most commonly on the legs and ankles. Women are more susceptible than men to develop them and those with blood relatives with spider veins are more predisposed to developing these roadmap veins. Heredity seems to play an important role in the development of spider veins. There is little scientific evidence that crossing the legs causes spider veins.
Hangnails are not nails at all, but little triangular pieces of skin at the edge of a fingernail that occassionally bleed and, are often, quite irritating. They are more common in the winter due to dry skin from the cold winter air but harsh chemicals, nail biting, and excessive hand washing can also cause the development of hangnails. If not properly cared for, hangnails can be the site at which bacteria enters the skin and causes an infection around the nail cuticle.
