At-home beauty devices: to buy or not to buy

At-home beauty devices: to buy or not to buy:

If you are thinking of buying a skin rejuvenation device as a holiday gift, think again.

Newswise — If you are thinking of buying a skin rejuvenation device as a holiday gift, think again.
“Most of them won’t do any harm, but they usually don’t do much good either,” said Amy McMichael, M.D., chair of the dermatology department at Wake Forest Baptist Health.

Before buying, McMichael advises people to try to verify the claims made in advertising by checking the manufacturer’s website for clinical trials’ data – not case studies – and FDA approval to ensure a product’s safety. If you can’t find information on the company’s website, check ClinicalTrials.gov.
“For example, microdermabrasion can be very helpful if done by professionals who are trained in the proper way to use the device,” McMichael said. “But at-home microdermabrasion products can be more damaging than helpful depending on the amount of pressure used. They can also spread bacterial infections or viruses that cause warts, so best to avoid.”

Overall, McMichael thinks people are better off using over-the-counter products, such as glycolic acid, serums and retin A creams, which are more effective, safer and less expensive than devices and tools. But check with a board-certified dermatologist for advice on what at-home products are best for your skin.

“Do your homework before you buy and look for products with some science to back up the marketing claims,” she said.

Higher weight increases risk of psoriasis | Newswise: News for Journalists

Higher weight increases risk of psoriasis | Newswise: News for Journalists:

 Studies have linked psoriasis and higher weight, but the causal relationship between the two has been unclear. What triggers what?

Newswise — Studies have linked psoriasis and higher weight, but the causal relationship between the two has been unclear. What triggers what?
Or could other underlying reasons explain the connection?
"Higher BMI may contribute to increased inflammation of the skin, which can exacerbate psoriasis, but it could also be that psoriasis leads to a person being less physically active and thus gaining weight," explains Mari Løset.
She is a medical doctor at the Department of Dermatology at St. Olavs Hospital and a postdoctoral fellow at the Norwegian University of Science and Technology's (NTNU) K.G. Jebsen Center for Genetic Epidemiology.
Løset is part of a team that been involved in a study of the causal relationship between BMI and psoriasis.
BMI stands for body mass index and is a measure of body fat content. It is calculated from a person's height and weight.
The observational study is a large collaboration among researchers from NTNU, England and North America. Some of the data being used is from the Health Survey in Nord-Trøndelag (HUNT) and the UK Biobank. Together, the analyses include data from 750 000 individuals.
Psoriasis is a chronic inflammatory condition of the skin, which causes a red, scaly rash. The cause of the disorder is probably multifactorial, involving both heredity and the environment.
Worldwide, two to four per cent of the population is affected by psoriasis. The incidence is particularly high in Norway.
"Self-reported data from two large population surveys in Norway indicate that six to eleven per cent of the population may be affected in this country," says Løset.
A study in the city of Tromsø has shown that the incidence of psoriasis was 4.8 per cent in 1980, but had increased to 11.4 per cent in 2008.
"Similar studies from other parts of the world substantiate the fact that the condition is increasing," says the postdoctoral fellow.
To investigate the causal relationship between BMI and psoriasis, the researchers used a method called Mendelian randomization. It is named after Gregor Mendel, who is known as the father of genetics.
According to Mendel's principles of inheritance, whether we inherit a certain variant of genes from our mother or our father is random. Genetic variants are randomly distributed, or randomized, between individuals.
"Mendelian randomization means that nature itself distributes individuals randomly into groups based on genes. This way, we can avoid the results being influenced by external factors," says Løset.
"Our understanding of how genes are related to disease is increasing at record speed, and in this study we used known genetic variants as markers for BMI and psoriasis," she adds.
By using Mendelian randomization, the researchers found that higher weight is a contributing factor to psoriasis. They observed that greater BMI increased the chance of getting the disease.
"We calculated that the risk increased by nine per cent for each higher whole number on the BMI scale," Løset says.
But the researchers are still uncertain about just how higher weight can lead to psoriasis.
"We still don't know enough about the mechanisms behind this connection. Fatty tissue is an organ that produces hormones and inflammatory signalling molecules, which could be a contributing factor," says Løset.
So far, not much research has been done on whether weight loss can cause psoriasis to disappear, although a few clinical studies suggest the possibility.
"Psoriasis is a very complex disease and we hope to study subgroups, especially individuals with severe psoriasis. The hypothesis is that we will be able to observe even greater links with higher weight," says Mari Løset.

Microneedling: Experienced Hands Can Improve the Face

Microneedling: Experienced Hands Can Improve the Face:

 This could be the answer to facelifts.


Microneedling treatments can improve the appearance of large pores, fine lines and wrinkles, scars, and stretch marks, but at-home devices won’t provide the same effects as an in-office treatment from a board-certified dermatologist.

 Interesting findings about Melanoma.  Take great care when out in the sun.


Newswise — ORLANDO, Fla. (March 3, 2017) — On average, one person dies of melanoma, the deadliest form of skin cancer, every hour. Because this disease can affect anyone, everyone should take steps to reduce their risk and catch melanoma in its earliest stages, when it’s most treatable.

New research presented at the American Academy of Dermatology’s 2017 Annual Meeting in Orlando, Fla., emphasizes the importance of skin cancer prevention and detection. Researchers examined data collected from 118,085 individuals who received a free skin cancer screening through the AAD’s SPOTme® program in 2009 and 2010, and approximately one-third of those surveyed indicated that they had recently observed a change in the size, shape or color of a mole — one of the major warning signs of melanoma.

Childhood Eczema



Trials are going on in the UK to ascertain whether silk underwear for children with eczema actually helps with this condition.  For this reason children with moderate or severe eczema are sought.   Professor Kim Thomas at the University of Nottingham, Centre of Evidence Based Dermatology will lead this trial.   This work is being funded by the National Institute for Health Research and involves NHS Trusts in Nottingham, London, Cambridge, Portsmouth and the Isle of Wight .  
Children enrolled on this scheme will participate for eight months.  If you have a child and would like to enrol it in this sceme you can email: clothes@nottingham.ac.uk

Teledermatology App System Offers Efficiencies and Can Reliably Prioritize Inpatient Consults

 This article about an App System will be so helpful in consulting people with skin conditions where they are without a personal consultation.  This would hopefully go a long way to cutting down waiting times in Surgeries.  So many consultations are now done via Skype anyway and it saves travel to the centre as well.
