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.
SHAVING MAKES HAIR GROW BACK THICKER
Hair does not grow any faster and does not get any thicker if you shave. As hair grows out, however, the blunt tip of the hair may cause the area to feel coarse or "stubbly" for a short period of time. A hair fiber is made of a protein called keratin. The visible portion of the hair that is cut by shaving has no biological activity. Since this "dead" hair shaft cannot send information about being cut to the hair follicle (the site of hair growth), growth continues as usual. Similarly, clipping a fingernail, also made of keratin, does not cause the fingernail to grow any slower or faster because it was trimmed.
Early research done in 1928 by forensic anthropologist Mildred Trotter, published in the journal, Anatomical Record, found that shaving had no effect on hair color, texture or growth rate. More recently, a study in the Journal of Investigative Dermatology also concluded, "No significant differences in total weight of hair produced in a measured area, or in width or rate of growth of individual hairs, could be ascribed to shaving."
False: Shaving does NOT cause hair to grow back thicker.
DARK EYE CIRCLES
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.
There are few scientific studies about the cause of this condition. Some blame fatigue, and for some, a few good nights of sleep does seem to remedy the situation. But for others, even getting 8 hours of sleep regularly doesn't seem to help. For some, it runs in the family, "mom has it" and "grandma had it." As we age, the skin thins, the fat under the skin atrophies allowing the blood vessels around the eyes to become more obvious. As a consequence the skin appears darker. Dark circles around the eyes are often accompanied by puffiness under the eyes and are a mere result of shadows that are cast due to the puffiness. Disorders that increase lower lid sagging, by increasing water retention, can worsen the appearance of dark circles (thyroid disease, kidney disease, and heart ailments.) Sleeping in a more upright position using pillows to elevate the head seems to improve puffiness for some, but for others, it seems to make no difference. Eczema sufferers often have inflammation around the eyes. This inflammation may leave a footprint of pigment around the eyes called Post-inflammatory Hyperpigmentation. Constant rubbing or scratching the area exacerbates the problem. Treating the eczema may often lighten the dark circles around the eyes. Sun exposure may induce the production of pigment around the eyes. When outdoors, always wear sunscreen and UV protective sunglasses.
Since there are many causes of dark eye circles, there is no real consensus on treatment. The following recommendations, however, may improve the condition:
- Get adequate sleep (8 hours/night)
- Sleep with extra pillows elevating the head
- Wear broad spectrum sunscreen daily (SPF 30+)
- Wear sunglasses with UV protection
- Apply cool compresses to relieve puffiness
- Moisturize the area twice a day
- Cover up with a concealer
Seek medical attention to manage allergies and eczema and to rule out any underlying medical cause.
Note: Various treatments available from your dermatologist include topical depigmenting products, chemical peels, injectable fillers, and various light and laser therapies.
