Although it's meant to protect the skin, a cooling technique may actually boost the risk of hyperpigmentaion (discoloration) in dark-skinned patients after laser treatment for mole-like skin lesions, Thai researchers warn.
"It is not life-threatening, but postinflammatory hyperpigmentation may cause substantial psychological problems," wrote a team from Mahidol University in Bangkok. "The treatment of postinflammatory hyperpigmentation is difficult and time-consuming, often lasting many months to achieve the desired results, which causes frustration in patients and physicians," they added.
Some experts have suggested that skin cooling -- which decreases pain and allows the use of higher laser frequencies -- may help reduce hyperpigmentation after laser treatment.
In this study, researchers used laser irradiation to treat 23 Thai women (average age 43) with Hori's nevus, blue-brown pigmented spots on the skin that develop later in life.
"One randomly selected face side of each patient was cooled using a cold air cooling device during and 30 seconds before and after laser irradiation, and the other side was irradiated without cooling," the researchers wrote.
Hyperpigmentation in the patients was assessed before treatment and one, two, three, four and 12 weeks after treatment.
Of the 21 patients who completed the study, 13 (62 percent) developed hyperpigmentation on the cooled side of the face, five (24 percent) developed the condition on the uncooled side, one patient (five percent) developed it on both sides of the face, and two (10 percent) did not have any hyperpigmentation.
The cooled sides were also three times more likely to develop hyperpigmentation than the uncooled sides, the authors said. Most cases developed two weeks after treatment. All but one of the cases were completely resolved 12 weeks after treatment.
The study was published in the September issue of the journal Archives of Dermatology.

For hundreds of years it’s been understood that water cleanses the skin of dirt and pollutants and that regular cleansing is not only indicative of good hygiene, it leads to better health. Unfortunately, that’s not the whole story. Water, while imperative to every facet of our lives, can actually remove skin’s natural moisturizing factors. Extended exposure to the warmer waters of a bath or shower can be particularly harmful. Cleansing agents in many body washes and bar soaps break down the skin’s natural moisture barrier, allowing moisture loss and leading to the itchy discomfort caused by dry skin.
“Prolonged exposure to water can be drying for skin, so it’s important to protect skin while in the shower,” said Dr. Karl Wei, Principal Scientist with P&G Beauty.
To understand how this happens, it becomes necessary to look into the top layer of epidermis called the stratum corneum. The stratum corneum is made up of 15-20 layers of cells known as corneocytes which are separated by natural oils or lipids. The corneocytes and lipids are responsible for holding moisture in the skin but, unfortunately, are also easily compromised.
When the skin’s necessary, natural oils are washed away, some clients will apply a moisturizer. However, many women lack the time, knowledge or convenience to replenish the lost lipids after they bathe. This can lead to dry skin and can exacerbate skin that is already dryer than average.

Taking an extra 60 seconds to examine your feet when you clip your toenails could save your life, says the American College of Foot and Ankle Surgeons.
Routine self-examination of feet can help detect deadly melanoma skin cancer at an early stage, when it's easiest to cure. Half of people diagnosed with melanoma of the foot die within five years, because the cancer had already spread through their bodies by the time it was diagnosed, the college said.
In cases where melanoma is detected early, 92 percent of patients are still alive after five years.
Doing routine checks of your feet increases the likelihood that you'll spot suspicious moles, freckles or other irregularities. The college recommends you focus on the three most common areas for foot melanoma: the soles, between the toes, and around or under the toenails.
See a doctor immediately if you notice a mole, freckle or spot that starts to change over the course of a month and becomes asymmetrical or changes its border, color, diameter, or elevation.
Melanoma can develop anywhere on the body, including areas that receive little sun exposure, such as the feet and ankles.

Learn how science is advancing in trimming treatments targeted at cellulite.
Speaking today at the American Academy of Dermatology’s Summer Academy Meeting 2007, dermatologist David J. Goldberg, MD, JD, FAAD, clinical professor of dermatology and director of laser research at the Mount Sinai School of Medicine in New York, N.Y., discussed the rapidly expanding area of skin-tightening techniques and how they can safely and effectively treat sagging skin on the jowls, neck, arms, and stomach, as well as cellulite.
Hispanic-American teens are more likely than their white peers to take risks that boost their odds for skin cancer, a new survey finds.
Reporting in the August issue of the journal Archives of Dermatology, a team at the University of Miami's Miller School of Medicine surveyed 369 high school students (221 white Hispanics and 148 white non-Hispanics).
They found that Hispanic teens were more likely to use tanning beds, less likely to consider themselves at risk for skin cancer, and less likely to protect themselves from the sun.
Compared to white non-Hispanics, white Hispanics were:
- More likely to tan deeply (44.2 percent vs. 31 percent).
- About 1.8 times more likely to never or rarely use sun-protective clothing.
- About twice as likely to never or rarely use sunscreen.
- 2.5 times more likely to have used a tanning bed in the previous year.
- 60 percent less likely to have heard of skin self-examination and 70 percent less likely to have been told how to do it.
- Less likely to think they had an average or above-average risk for skin cancer (23.1 percent vs. 39.9 percent).
There's a real need to improve participation of white Hispanic students in skin cancer prevention programs, the authors concluded.
Exposure to the sun's ultraviolet (UV) rays is a major risk factor for skin cancers, and a person's majority of lifetime UV exposure occurs by age 18, the Miami team noted. White Hispanics have a lower rate of skin cancer than white non-Hispanics, but white Hispanics are more likely to be diagnosed with more advanced skin cancer.
