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.
The classical rash is a red blistering eruption seen in straight lines due to the way the plant brushes against the skin. If contact to the resin is a result of touching a piece of clothing, or from touching a pet that has been romping through the woods, the rash may appear more spread out. Inhaling smoke from a burning poison ivy, sumac, or oak plant may even cause a dangerous irritation to the nasal passges and lungs.
Once the oil resin is on the skin, it can be spread to other parts of the body by sctratching. Rhus dermatitis is often a very itchy rash and if untreated may last for several weeks. The rash itself is NOT contagious.
If contact to any of these plants occurs, immediately rinse yourself off with lukewarm water. Use a cleanser to wash away any remnant oil resin from your skin. Oil from poison ivy can stick to many different surfaces. Wash the clothing that may have contacted the plant. Rinse off patio furniture, garden tools, golf clubs, and even the fur on a pet.
A mild case of poison ivy may be treated at home with calamine lotion, over-the-counter hydrocortisone cream and oral antihistamines to control the itch. Do not open a blister as this may lead to infection. Cool compresses may help relieve the itchy symptoms. If the rash is severe or widespread, affects the face or genitals, if blisters are oozing pus, or if a fever develops, seek medical attention immediately.
BROAD SPECTRUM Explained
What does Broad Spectrum mean on a sunscreen label?
The sun emits two types of harmful rays: ultraviolet A (UVA) and ultraviolet B (UVB). UVA rays are the dominant tanning rays and are a major cause of skin aging and even skin cancer. UVB rays are predominantly the cause of sunburn and skin cancers, but can also contribute to the development of fine lines, dark spots and wrinkles. UVA rays penetrate through glass windows, UVB rays do not.
Broad Spectrum sunscreen protects against both UVA and UVB rays. Purchase sunscreen that says "broad spectrum" on the label!
COSMETIC VS. DRUG
A skincare product is considered a cosmetic or a drug, depending on its intended use. The U.S. Food and Drug Administration (FDA) defines cosmetics as "articles intended to be rubbed, poured, sprinkled, or sprayed on, introduced into, or otherwise applied...for cleansing, beautifying, promoting attractiveness, or altering the appearance." By law, cosmetics cannot claim to alter the structure or function of the skin.
Moisturizing is a cosmetic claim. A moisturizer that claims to decrease the "appearance" of fine lines and wrinkles by increasing the water content of skin is considered a cosmetic. Although skincare product manufacturers must follow the laws and regulations that apply to cosmetics, cosmetics do NOT require FDA approval before going to market. Skincare products must not be misbranded or adulterated but they do not need to PROVE efficacy or safety. They are recognized by the FDA as having no medical value.
Examples of cosmetics are as follows: facial and body moisturizers, including "eye" creams, "night" creams, "firming" creams, "toning" creams, "anti-aging" creams, and "anti-wrinkle" creams; lipsticks, fingernail polishes, and eye & facial makeup preparations.
Products that intend to change the structure or function of skin are considered drugs. The FDA defines drugs as "articles intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease" and "articles...intended to affect the structure or function of..." skin. If a product claims to alter the skin's structure or function, for example, by actually "removing" wrinkles or increasing the skin's production of collagen, it is considered a drug. As a drug, the product must get FDA approval before going to market. In addition, the manufacturer must prove the product's safety and efficacy.
Manufacturers of over-the-counter (OTC) skincare moisturizers, including "eye" creams, "night" creams, "firming" creams, "toning" creams, "anti-aging" creams, "anti-wrinkle" creams, or rejuvenating serums, cannot claim that their product will change the structure of the skin itself. The product may claim to change the "appearance" of fine lines and wrinkles (by increasing the water content of the skin), but, by law, cannot claim to change the actual structure or function of the skin.
MOISTURIZERS: BEST EXFOLIANTS
In healthy skin, there is a normal physiological balance between the production of new cells and the shedding of the old ones. The outmost layer of skin, the stratum corneum, is approximately 20 layers of non-living, yet functional, cells called corneocytes. They are held together by protein bridges called desmosomes. Desquamation is the process by which these protein bridges are enzymatically dissolved allowing the shedding of the most superficial cells. The enzymes responsible for dissolving these bridges can only function in a well hydrated environment. When the water content in the outer layer of skin decreases, these enzymes become ineffective and can not dissolve the desmosomes. The retention of these most superficial cells makes the skin look dry and scaly.
Quality moisturizers help increase the water content of the outer layer of skin increasing the activity of the enzymes that break the protein bridge connections between corneocytes. This allows for appropriate shedding of old superficial skin cells resulting in soft smooth hydrated skin.
THE DREADED CELLULITE
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.
Cellulite is more common in women than men and it is not an indication of being overweight, however, losing weight may reduce the appearance of cellulite. Cellulite is less noticeable in darker skin so applying a self-tanner may make the dimples on the thighs less evident. The presence of cellulite tends to run in families. Inactivity and weight gain may make cellulite more noticeable.
There are many products and treatments that promise to rid of those lumps and bumps on the thighs but there is very little scientific evidence that prove any of them are very effective. Creams containing aminophylline and caffeine are often touted as effective treatments, but to date, no double-blinded control studies prove their efficacy.
Liposuction is effective in removing deeper fat but is not effective in removing cellulite and has even been shown to worsen the appearance of cellulite possibly by creating more depressions in the skin. Massage treatments may remove tissue fluid giving a temporary improvement in the appearance of cellulite.
The most promising treatment for cellulite, although still far from perfect, is a system that uses lasers and radiofrequency systems. Combinations of tissue massage with diode laser therapy or tissue massage with infrared light and radiofrequency may offer improvemnets to cellulite after a series of treatments. Results may last 6 months to a year.
