What is cryomodulation and nanosecond pulsed electric field treatment?


October 14th, 2020 | General Info

Cryomodulation and nanosecond pulsed electric field treatment are two new technologies for the treatment of benign lesions like seborrheic keratoses. Cryomodulation is a technique using cooling technology to treat sunspots and seborrheic keratoses. The first to market device is Glacial RX by R2 Technologies.

Another new technology is nanosecond pulsed electric field treatment, which is a nonthermal, energy based technology used to treat seborrheic keratoses and other conditions. It will be interesting to see how effective these two new technologies will be.

Needle Size May Affect Soft Tissue Filler Properties


October 14th, 2020 | General Info

A recent article in Dermatologic Surgery suggests that injectors (and patients) should be aware of the effects of needle size on the properties of fillers. Various types of fillers (monophasic and biphasic) were injected through 30G needles and the size and properties of the fillers were analyzed after they had been injected through the needles.  

Both monophasic (e.g. Juvederm products) and biphasic (e.g. Restylane) fillers were affected by the smaller needle size. They were affected in terms of the size of the extruded particles and in the properties (G’) of the extruded particles. Interestingly, biphasic fillers seemed to be affected more than monophasic fillers. In addition, larger particles seemed to be affected more than smaller particles as we would intuitively expect. 

Injectors should consider the size of the needle being used to inject fillers (especially biphasic fillers and fillers of larger particle size) as this might affect the performance and durability of the filler.

Nuceiva–the Newest Botulinum Toxin on the Market


October 4th, 2020 | General Info

Nuceiva Edmonton

Nuceiva is the newest neuromodulator on the market for the treatment of glabellar frown lines. Whereas Botox is referred to as abobotulinumtoxin A, Nuceiva is referred to as prabotulinumtoxin A.

Similar to other brands such as Botox, Xeomin, and Dysport, Nuceiva™ works to smooth out creases in the face by decreasing muscle contraction.

It has been approved by Health Canada and the FDA.

Marketed as Jeuveau by a company called Evolus in the United States, it originated with a South Korean company called Daewoong. Nuceiva™ was authorized for sale by Health Canada in August of 2019 and was subsequently officially brought to the Canadian market by Clarion Medical Technologies in October 2019. It is also available in the European Union.

Nuceiva™ usually lasts about 3 to 4 months although this varies from person to person. A study published in Dermatologic Surgery in 2019 showed similar efficacy to Botox.
