The findings from a new study suggest another reason why diets that contain low glycemic loads may be of benefit. Not only can they improve insulin sensitivity, this type of diet also appears to clear up acne as well.
Data from earlier studies suggest that dietary factors such as the glycemic load are involved in the pathogenesis of acne. Therefore, changes in diet could impact symptoms of this common skin disease, the researches hypothesize.
Foods that produce a high glycemic load—or high levels of blood glucose—such as white bread and potatoes tend to cause a rapid surge in blood sugar. Conversely, other carbs, such as high-fiber cereals or beans, create a more gradual change and are considered to have a low glycemic index.
Dr. Robyn N. Smith, from the RMIT University in Melbourne, Australia, and colleagues assessed acne symptoms in 43 male patients, between 15 and 25 years, who were randomly assigned to a low glycemic load diet or a normal diet for 12 weeks. The intervention diet consisted of 25% energy from protein and 45% from low-glycemic-index carbohydrates.
The findings are published in the July issue of the American Journal of Clinical Nutrition.
The low-glycemic diet was associated with a significant reduce in total acne compared with the normal diet. In addition, the low-glycemic diet produced significantly greater reductions in body weight and body mass and a greater increase in insulin sensitivity. Insulin resistance is a condition in which the body’s cells become insensitive to the effects of insulin, so the body’s response to a normal amount of insulin is reduced. As a result, higher amounts of insulin are needed for this hormone to work in the body.
Smith and her associates point out that this study is the first randomized controlled trial to examine the influence the effects of glycemic load on acne.
“Although we could not isolate the effect of the low glycemic load diet from that of weight loss,” they add, the findings support the hypothesis of a relationship between acne and high insulin levels.

Botox and plastic surgery may promise to reduce wrinkles and worry lines, but some New Yorkers are turning to facial yoga to achieve a youthful appearance.
At a recent class in Manhattan’s wealthy Upper East Side, yoga instructor Annelise Hagen teaches several facial exercises designed to stretch and tone facial muscles.
A group of women practice moves including “The Lion,” showing the tongue hanging out and eyes rolled up. Hagen encourages class members to hold the position for 60 seconds, joking: “You can do this any time. It really helps you get a seat on the train.”
Hagen recently released a book, The Yoga Face: Eliminate Wrinkles with the Ultimate Natural Facelift (Avery, 2007). She said she developed a workshop using facial yoga because women wanted to look their best, “but they weren’t really thinking about how to exercise their facial muscles.”
She said facial muscles become weak and flabby and need regular workouts and circulation to reduce wrinkles.
Besides “The Lion,” other exercises include “Satchmo,” in which the cheeks are blown out Louis Armstrong-style, and ”Marilyn,” in which glamorous kisses are blown to strengthen mouth muscles for full and firm lips.
“It uses the same principles of exercise you would use for any other parts of your body,” Hagen said. “Facial muscles also become more toned, so it is a natural way of getting a lift.”
Hagen recommends facial yoga for those wanting to find outer and inner beauty, saying, “the emotional aspect is just as important as the physiological.”
But she does not rule out plastic surgery or Botox. “I don’t rule it out for myself. One day I may feel like I need that. But regardless, maintaining elasticity and tone is really crucial, especially if you have had Botox and plastic surgery,” she said.
While making faces in front of strangers might intimidate some, those who attended the class thought it the perfect way to combat busy New York lifestyles. “Working in New York is very stressful,” Kathy Healey said. ”It’s a perfect way to end the week.”

Although acne is oftentimes as much a part of being a teenager as dating and Friday night football games, a new study examining the prevalence of acne in adults age 20 and older confirms that a significant proportion of adults continue to be plagued by acne well beyond the teenage years. In particular, women experience acne at higher rates than their male counterparts across all age groups 20 years and older.
In the study entitled, “The prevalence of acne in adults 20 years and older,” published online in the Journal of the American Academy of Dermatology, dermatologist Julie C. Harper, MD, FAAD, associate professor of dermatology at the University of Alabama in Birmingham, Ala., and her colleagues at the University of Alabama at Birmingham School of Medicine, surveyed a random sample of men and women aged 20 and older to determine the prevalence of persistent acne that continued after adolescence or new adult-onset acne.
“Although acne is one of the most common skin diseases, there is a general misconception that it only affects teenagers,” explained Dr. Harper. “As dermatologists, we treat acne patients of all ages – from those who have experienced acne since they were teenagers to others who have developed the condition for the first time as adults. Our study set out to determine just how common acne is among adult men and women.” A total of 1,013 men and women aged 20 years and older at the University of Alabama at Birmingham campus and medical complex were asked to complete a one-page questionnaire designed to evaluate the prevalence of acne in adults across various age groups. Survey questions gauged whether the participant had ever had acne or pimples, including during their teens or later in life (in their 20s, 30s, 40s, and 50s or older). The survey also asked participants to judge whether their acne had become better, worse or stayed the same since their teenage years.
When asked whether they had ever had a pimple or acne, the vast majority (73.3 percent) of participants responded that at one time or another they had dealt with acne. The majority also reported that they had experienced acne as teenagers, with the number of men and women affected by the condition nearly identical (68.5 percent of male participants and 66.8 percent of female participants).
Interestingly, the survey found that for every age group following the teenage group, the reported
incidence of acne was significantly higher among women than men. Specifically,
- During their 20s, 50.9 percent of women and 42.5 percent of men reported experiencing acne.
- During their 30s, 35.2 percent of women and 20.1 percent of men reported experiencing acne.
- During their 40s, 26.3 percent of women and 12 percent of men reported experiencing acne.
- During their 50s or older, 15.3 percent of women and 7.3 percent of men reported experiencing acne.
A separate section of the survey, which included questions assessing aspects of acne specific to women, asked female participants to note changes in acne around the time of their menstrual period, their pre-menopausal or post-menopausal status, and the effect of any treatments for symptoms of menopause on acne. Of the pre-menopausal women surveyed, 62.2 percent noted that their acne gets worse around the time of menstruation. In addition, of the 86 women who reported using either hormone replacement therapy or over-the-counter medications for the side effects of menopause, nine women (10.5 percent) reported improvement in their acne with the use of these therapies. However, 75 of the women (87.2 percent) reported no change with these menopausal therapies, and two women (2.3 percent) reported that their acne symptoms worsened.
“Our findings demonstrate that acne is a persistent problem for people of all ages, but clearly women seem to be affected by this medical condition more than men when we examined the 20-plus age groups,” said Dr. Harper. “Research examining the role hormones play in the development of acne may hold the key to explaining why more adult women are affected by acne and could lead to future treatments to control this condition.”
Dr. Harper added that the majority of study participants reported that the severity of their acne improved after their teenage years, which is consistent with previous studies suggesting that post-adolescent acne is generally mild or moderate. For example, 63 percent of men and 53.3 percent of women stated that their acne improved after their teenage years, while only 3.6 percent of men and 13.3 percent of women reported that their acne worsened post-adolescence.
“Despite the fact that adult acne tends to be generally milder than teenage acne, this common medical condition can have a significant impact on a person’s overall quality of life – regardless of when it occurs,” explained Dr. Harper. “Involving a dermatologist in the diagnosis and treatment of acne is vital to managing this difficult condition.”
The American Academy of Dermatology recommends the following tips for the proper care and treatment of acne:
- To prevent scars, do not pop, squeeze or pick at acne; seek treatment early for acne that does not respond to over-the-counter medications.
- Gently wash affected areas twice a day with mild soap and warm water. Vigorous washing and scrubbing can irritate your skin and make acne worse.
- Use “noncomedogenic” (does not clog pores) cosmetics and toiletries.
- Use oil-free cosmetics and sunscreens.
- Avoid alcohol-based astringents, which strip your skin of natural moisture.
- Shampoo hair often, daily if it is oily, though African-Americans may prefer to wash it weekly.
- Use medication as directed and allow enough time for acne products to take effect.

Female smokers may be much more likely to develop non-inflammatory acne (NIA) than women who don't smoke, says an Italian study in the British Journal of Dermatology.
Researchers looked at more than 1,000 women and found that 40 percent of those who smoked had NIA, compared with 10 percent of nonsmokers. Blocked pores, large white heads and small cysts are characteristic of NIA, BBC News reported.
The team at the San Gallicano Dermatological Institute in Rome said they conducted the study in women because the condition seems to be more prevalent in women than in men. Compared to nonsmokers, smokers in the study had half the levels of skin secretions of vitamin E and had other skin-related variations. The study also found that smokers who had acne in their teens were four times more likely to suffer NIA than nonsmokers who experienced teen acne.
The findings add to previous research that links smoking with acne, Colin Holden, president of the British Association of Dermatologists, told BBC News.
