Published Why men, wealthy people and maritime residents are more likely to develop skin cancer (via sciencedaily.com)
A new study examines why people living in Atlantic regions are more at-risk for developing melanoma than other Canadians, providing lessons on skin cancer prevention for the whole country. To find out why, the researchers compared UV exposure and behaviours among different groups in Atlantic Canada based on income, education, and gender, among other factors.
Published Why does skin get 'leathery' after too much sun? Bioengineers examine cellular breakdown (via sciencedaily.com)
A study explores how ultraviolet radiation can alter the microstructure of human skin. Particularly affected is collagen, the fibrous protein that binds together tissue, tendon, cartilage and bone throughout our bodies.
Published Boosting the body's anti-viral immune response may eliminate aging cells (via sciencedaily.com) Original source
Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published Scientists see anti-aging potential in an invasive weed (via sciencedaily.com) Original source
The fruit of the cocklebur plant, which grows worldwide and is often considered a noxious weed, has antioxidant and anti-inflammatory components that could make it useful as a skin protectant, according to new research.
Published Simple laser treatments may help prevent nonmelanoma skin cancer (via sciencedaily.com) Original source
In a study of patients with a history of facial keratinocyte carcinoma, 20.9% of those treated with nonablative fractional lasers experienced a subsequent keratinocyte carcinoma, compared with 40.4% of patients who did not receive laser treatment.
Published In cells, UV-emitting nail polish dryers damage DNA and cause mutations (via sciencedaily.com) Original source
The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers studied these ultraviolet (UV) light-emitting devices, and found that their use leads to cell death and cancer-causing mutations in human cells.
Published Scars mended using transplanted hair follicles (via sciencedaily.com)
Researchers have found that hair follicle transplants can promote scar rejuvenation by altering their architecture and genetic makeup.
Published Researchers develop painless tattoos that can be self-administered (via sciencedaily.com) Original source
Researchers have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics.
Published Researchers produce nanodiamonds capable of delivering medicinal and cosmetic remedies through the skin (via sciencedaily.com)
A novel approach provides an innovative solution to overcoming two major challenges in delivering medicinal and cosmetic remedies through the skin. Combining techniques in nanotechnology and optics, researchers produced tiny (nanometric) diamond particles so small that they are capable of penetrating skin to deliver these remedies. Next, they created a safe, laser-based optical method that quantifies nanodiamond penetration into the various layers of the skin and determines their location and concentration within body tissue in a non-invasive manner -- eliminating the need for a biopsy.
Published Microneedling beats chemical peels for acne scar treatment (via sciencedaily.com) Original source
Chemical peels are a common treatment for acne scars, but a new study finds that microneedling is significantly more effective for patients with dark skin.
Published Those with facial scars rate their own appearance more critically than surgeons and strangers (via sciencedaily.com) Original source
Patients who undergo facial surgery think their surgical scars look worse than surgeons and independent observers do, according to a new study.
Published New hair dyes avoid allergic reactions (via sciencedaily.com) Original source
Researchers have developed a range of permanent hair dyes that avoid the allergenic properties of traditional formulations.
Published Can we go from scarface to scarless? (via sciencedaily.com) Original source
Researchers examined skin regeneration over two years in various body parts of the adult newt, Cynops pyrrhogaster. Their wounds were very quickly healed over several days without prolonged inflammation. Because of this rapid healing, granulation/dermal fibrosis, and therefore scarring, did not occur. The skin was able to fully regenerate. These findings provide evidence that this newt species may be an ideal model system to study and prevent scar formation in human skin.
Published New drug molecules could prevent skin aging caused by sun exposure (via sciencedaily.com)
Two new molecules that generate minute amounts of the gas hydrogen sulfide have been found to prevent skin from aging after being exposed to ultraviolet light found in sunlight. Sunburn is a major cause of premature aging in skin, and a primary risk factor for skin cancer, and other skin problems associated with aging. Now, an international research team has made inroads towards being able to reverse or delay this damage for the first time.
Published Internal compression stocking helps against varicose veins (via sciencedaily.com) Original source
A new study finds that rather than destroying or removing defective veins, it is possible to repair them by using a sheath. They are thus saved for later use as a bypass.
Published 3D 'bioprinting' used to create nose cartilage (via sciencedaily.com) Original source
A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.
Published 90% of young women report using a filter or editing their photos before posting (via sciencedaily.com)
Ninety per cent of women report using a filter or editing their photos before posting to even out their skin tone, reshape their jaw or nose, shave off weight, brighten or bronze their skin or whiten their teeth. Young women in the study also described regularly seeing advertisements or push notifications for cosmetic procedures -- particularly for teeth whitening, lip fillers, and surgery to enhance face and body features.
Published Hair aging differs by race, ethnicity (via sciencedaily.com) Original source
While aging is an unavoidable biological process with many influencing factors that results in visible changes to the hair, there is limited literature examining the characteristics of hair aging across the races. Now a new study describes the unique characteristics of hair aging among different ethnicities that the authors hope will aid in a culturally sensitive approach when making recommendations to prevent hair damage during one's life-time.
Published A new way to create a spectrum of natural-looking hair colors (via sciencedaily.com) Original source
Northwestern University researchers have developed a new way to create a spectrum of natural-looking hair colors, ranging from blond to black, by using enzymes to catalyze synthetic melanin.
Published Planaria flatworms can be alternative screening tool to avoid rabbit skin testing (via sciencedaily.com)
A new, accurate screening tool for clinical skin products has been developed which uses flatworms rather than rabbits.
