chocolates_short2

Reading at a magazine while waiting at the doctor’s office I found an article that talked about chocolates and acne. The article explained how a group of teens were put to eat chocolate while another group ate a similar product that didn’t contain chocolate. The results: teens that ate chocolate group didn’t have any significant worsening of their acne condition.

I was actually 15 by the time I read that article, since then I have elaborated the idea, I have read other people’s opinion about it, and I have commented the results with my patients.  However once in a while I have found people emphatically telling me that they would always get more pimples after eating chocolates or other high caloric food.

The truth is that in the past couple of years, there has been an increased interest on the effects of diet in acne. Results suggest that low glycemic index diets can actually decrease the size of the sebaceous glands. Regarding chocolate itself, investigators have communicated they may actually trigger the immune system to release mediators that may cause inflammation on the skin.

These findings are still accumulating but in the meantime it is good to get become familiarized with the high and low glycemic index food in order to choose the best type of food that help you get less lesions and actually have a healthier lifestyle.

According with the American Diabetes Association carbs with high glycemic index include sugar, white bread, white rice, corn flakes, bran flakes, bagels, pumpkin, pretzels among others. That’s the type of carbs you want to stay far from. Low glycemic index food include dried beans, corn, yam, oat meal, all non-starchy vegetables, sweet potatoes, most fruit, and many whole grain breads and cereals. That is the good carbs you want to choose.

High GI carbs rise a hormone called insulin in a way that may be dangerous for your skin and your health in general in the long term. Eating low GI carbs not only may help to reduce the number of pimples but it certainly prevents other diseases such as diabetes.

Blue_Light_Acne_TreatmentDifferent light-based therapy have been used to treat acne, specifically targeting Propionibacterium acnes (P. acnes) and modulating the body’s defense response.

P. acnes naturally produces porphyrins, substances that strongly absorb light. The role of light devices is to activate porphyrins and ultimately produce singlet oxygen which will result in bacterial death but also destroy sebaceous glands .

Photodynamic therapy has been available for around 15 years. Its effectiveness has been well demonstrated, the main disadvantage has been its side effects which include pain, erythema an hyperpigmentation. In the past years, several protocols have been adjusted to provide better tolerance and more effectiveness.

New devices using narrow band ultraviolet light (NB-UVB) has proved to inhibit P acnes with a relatively low dose. We have also previously known that NB-UVB modulates the body defense response mediated by cells creating a synergistic effect.

We expect promissory results from short courses of NB-UVB therapy in combination with other local treatments available depending on the severity of acne lesions.

Nitric-Oxide

Propionibacterium acnes or P. acnes, is a bacteria involved in the development of acne lesions. For years topical antibiotics such as erythromycin or clindamycin have been recommended as a part of acne therapy to combat this bacteria; however increased concern has risen due to the emerged resistance of P. acnes to this type of drugs.

Topical benzoyl peroxide is an alternative of topical antibiotics, it is not expensive and doesn’t create resistance. However some people cannot tolerate its side effects which include skin irritation, peeling, itching, and redness.

The development of topical nitric oxide may provide with an alternative to topical antibiotics. Nitric oxide is naturally synthesized by the human body in response to bacteria, it has a low propensity for resistance and it could even reduce sebum production.

Results of studies made with this component are going to be presented in the World Congress of Dermatology this year.

Acne is a common condition that affects 80% of adolescents and young adults from the ages of 11 to 30. However the common belief that you will soon outgrow the disease is not always correct. It’s been reported that around 42.5% of men and 50.9% of women continue to suffer from this condition into their adulthood.

It’s location upon the face is apt to be a possible source of great annoyance and embarrassment, not only just to teenagers but also to young adults.

Although acne lacks the urgency of a life-threatening condition, it produces long term ramifications that can be coming up with cutaneous and emotional scars lasting lifetime. It debilitates an individual’s confidence causing physical, social, and psychological sufferings and reduces self-esteem.

What causes acne?

Certain facts are known about acne: the primary factors involved in the onset of acne are increased sebum production, abnormal keratinization, inflammation, and bacterial colonization by Propionibacterium acnes. However it is considered that acne is not an infectious disease, it’s more an inflammatory process and the role of P. acnes is more inflammatory than infectious.
