  • DermNews: British Report Finds Tattoos Could Cause Cancer


Tattoos may not just be skin deep.
According to a report published in The Sunday Times on September 22nd, toxins from tattoo ink could be absorbed into the body and cause cancer. The study, conducted by England’s Bradford University Centre for Skin Science, suggests that ink nanoparticles could enter the bloodstream and accumulate in the spleen and kidneys, damaging the body’s ability to filter impurities. Collagen, the body’s connective tissue, can also be permanently damaged by the dyes.

  • Study, Doctors Report Undertreatment of Psoriasis is a Common Problem


Many psoriasis patients are undertreated and unhappy with their current treatment options, according to a new study published in JAMA Dermatology.


The study, which analyzed 5,604 patient survey results from 2003-2011, found that as many as 50% of patients with mild psoriasis receive no treatment for their condition, and more than 52% of patients are dissatisfied with their current treatment. A co-author of the study concluded, “Nontreatment and undertreatment of patients with psoriasis and psoriatic arthritis remain a significant problem in the United States. Efforts in advocacy and education are necessary to ensure that effective treatments are accessible to this patient population.”


These findings come as no surprise to Dr. John Koo, MD, Professor and Vice Chairman, UCSF Department of Dermatology, Director, UCSF Psoriasis Treatment Center Phototherapy Unit, “The tragedy is, a lot of dermatologists are not very aggressive. One of the problems for people with chronic skin diseases like psoriasis is they often have a hard time finding dermatologists willing to use aggressive treatments to clear their skin,” says Dr. Koo, “We have many great treatments available, but not every dermatologist is willing to offer them.”

  • Parabens, Blueberries & Skincare: 8 Facts That May Surprise You

Parabens, Blueberries, Antioxidants


Parabens hit the cultural mainstage in 2004, when a study found trace amounts in breast tissue from breast cancer patients. Since then “Paraben -free” has become a popular selling point for new cosmetic products, and “parabens” has become a hot topic on beauty blogs, where parabens are often debated, advised against, and purported as health threats that cause cancer and infertility. In spite of all this, parabens continue to be the most popular preservative for cosmetic products.


Are parabens actually dangerous, or is it all just heresy? We compiled a list 8 facts, courtesy of the dermatologists at Skin Therapy Letter. You be the judge.


1. Parabens have been used as a preservative for over 80 years, and they’re everywhere. Parabens have been used in cosmetic products since the 1930s. A 2011 study found them in 44% of cosmetics tested. They have been found in sunscreen, hand soap, body lotion, shampoo, conditioner, face lotion, facial cleansers, foundation, lipstick, mascara, hair spray/mousse/gel, and toothpaste.


In addition to human tissue, paraben levels have been detected in wastewater, rivers, soil and house dust.

  • The SPF Ratings Your Moisturizer Should Have


While many people consider sunscreens an absolute must for a day at the beach, they are often not considered for daily use as a skin care product.


The often messy application and greasy sheen left behind by sunscreen products discourages most people from making these products a part of their everyday skin care routine. No one wants to walk around looking like a glazed donut, right?


Unfortunately, skipping the sunscreen may result in detrimental effects on the skin over the long term, such as the appearance of fine lines and wrinkles, and in some cases, skin cancer.

  • How Smoking Accelerates Skin Aging



We all know the damage smoking does to the lungs and cardiovascular system, but do you know what it does to the health of your skin? The long-term effects may be much worse than you think.


Tobacco smoke contains a complex mixture of gaseous and particulate compounds, several of which may have the potential to exert physiologic and pharmacologic impacts. Various independent studies have shown that smoking has a degenerative effect on the skin.


Tobacco smoking induces oxidative stress, which has immunomodulatory effects by changing inflammatory cell function.  It also causes the release of proteolytic enzymes; which in turn alters connective tissue turnover and degrades skin connective tissue. Collagen production and the deposition of mature collagen in the extracellular tissue is also significantly reduced.1 In essence, this activity accelerates the skin’s natural aging process.

  • Study Finds Link Between Skin Cancer And Denial: How To Assess Your Cancer Risk + Take Action



A 2008 study of sun-protective behaviors conducted by The National Cancer Institute found that 68% of American adults, 85.6% of teenage girls and 92.6% of teenage girls reported that they did not wear sunscreen regularly when outside for more than an hour on a sunny day.


Those numbers are startling, given the prevalence of skin cancer and the wealth of sun protection information available. If you read this blog – or any health or skincare blog, for that matter – you’re probably already aware of the dangers of sun damage, but to refresh your memory, here are some statistics, straight from The Skin Cancer Foundation:

  • DermNews: New Study Finds Sunscreen Prevents Aging

A new study funded by the National Health and Medical Research Council of Australia found that regular sunscreen use reduces the wrinkling, spotting and loss of elasticity caused by photoaging.


Here’s how the study worked: Researchers gathered a group of 900 Australians with similar skin types (fair, prone to burning) and similar sun protection habits (tended to wear sunscreen at least some of the time.) Each participant received a “skin damage score” measured on a scale of 1 – 6, with 1 signifying no skin damage, and 6 signifying severe signs of aging.


The participants were then split into two groups and given separate instructions: Half of them were instructed to wear sunscreen daily, the other half were told to continue their usual sunscreen practices. Both groups agreed to carry out their assigned behaviors for the entirety of the study.

Chocolate and Sex Causes Acne?


Have you been told that you shouldn’t eat chocolate because it causes acne?

Or how about French fries? Pizza?


Wrong! That’s just a myth, and while some foods can make acne worse for some people, researchers have found that it does not cause it!


There is recent work from Australia that suggests that high carbohydrate foods may in some people flare their acne. The theory is that chronic consumption of high carbs stimulates the excessive production of insulin so that eventually more and more insulin is needed to assist glucose into cells. This is called insulin resistance. The higher insulin may drive the ovaries to produce more testosterone, which in turn encourages acne. This may be what is happening partly in a condition called polycystic ovary syndrome.


There are a number of myths about the causes of acne and how to treat it. Here are just a few:
