Machine That Combines US, RF Promising for Wrinkles, Pores and skin Laxity

SAN DIEGO – Combining radiofrequency and focused ultrasound demonstrated considerably higher enhancements within the high quality of wrinkles and pores and skin laxity within the facial area in contrast with radiofrequency alone at 3 months, outcomes from a multicenter blinded trial confirmed.

“We have finished numerous work with radiofrequency, and we have finished numerous work with ultrasound,” Suneel Chilukuri, MD, mentioned in an interview prematurely of a medical summary session on the annual convention of the American Society for Laser Medication and Surgical procedure. “The query turns into, is there really a distinction if we’re combining them collectively?”

To seek out out, Chilukuri, a dermatologist who practices in Houston, Tex., and colleagues carried out an IRB-approved trial of a brand new gadget that enables for the supply of radiofrequency (RF) and focused ultrasound (TUS) in a single applicator. The gadget, which isn’t but named, has been cleared by the Meals and Drug Administration and is predicted to be obtainable within the fourth quarter of 2022.

In a single‐blinded examine, 21 adults had been randomized to obtain RF and TUS (group A), whereas 20 acquired RF alone (group B). The imply age of sufferers was 57 years and 38 had been girls. Sufferers in every group acquired 4 full‐face remedies delivered as soon as per week. Chilukuri and colleagues used the ElastiMeter to quantitatively measure pores and skin properties at baseline, 1‐month, and three‐month observe‐up visits. Additionally they took digital photographs at every follow-up go to and utilized the Fitzpatrick Wrinkle and Elastosis Scale (FWS), and the International Aesthetic Enchancment Scale (GAIS scale) to every one, along with performing 3D evaluation.

Chilukuri reported that sufferers in group A confirmed superior enchancment of pores and skin elasticity in contrast with these in group B. At 3 months, the preliminary pores and skin elasticity information confirmed an enchancment within the periorbital area by 13.6 N/m (34.7% enchancment) and eight.1 N/m (22.2% enchancment) in group A and B, respectively. (N/m is a measure of elasticity.)

3D images additionally demonstrated superior leads to group A, attaining an enchancment of 5.3 factors (27.7%) and 4.6 factors (24.4%) in wrinkles and pores and skin evenness, respectively. These in group A achieved marked enchancment in each FWS and GAIS scales, in contrast with their counterparts in group B, he mentioned.

“I feel that is going to be yet one more very helpful, versatile instrument in our toolbox,” Chilukuri mentioned of the brand new gadget, noting that for each the investigators and the sufferers, there was larger remedy satisfaction for the areas handled with mixed radiofrequency and ultrasound. “It is one thing that is efficient, painless, and the remedy time could be very brief – roughly 10 minutes per facet. It is extraordinarily tolerable and the outcomes had been much like 6-month outcomes I get with fractionated ablative resurfacing, however with out the downtime, with out the handholding, with none ache.”

Furthermore, he added, many sufferers within the trial have requested to have additional remedies “and are on a ready checklist for when the product launches.”

He and his colleagues additionally noticed enhancements in pores and skin hydration amongst sufferers in group A, primarily based on readings from a MoistureMeterSC, which measures pores and skin hydration, a discovering that he characterised as “surprising and fascinating.”

Chilukuri speculated that combining TUS and RF permits for higher warmth dispersion into the dermis. “If you happen to get to the right temperature, which is someplace between 40 and 42 levels, and should you can hold it for about 10 minutes, we all know that there shall be correct stimulation of senescent fibroblasts,” he defined.

“I can not say that seborrheic keratosis is improved or hyperpigmentation is improved, however the warmth technology results in quick vasodilation to enhance blood movement to handled areas. That leads to quick collagen contraction in addition to improved autophagy, elimination of age-related mobile particles. With the long run neovascularization, you are going to see extra change with the fibroblast exercise resulting in collagenesis and elastogenesis.”

Use of the gadget will not be indicated for sufferers with steel implants within the head and neck area, he famous. “I might even be cautious about utilizing it in individuals with melasma because the gadget’s mechanism is predicated on warmth,” since present scientific proof reveals that warmth can worsen melasma, he added. “For now, I like to recommend warning till we carry out a split-face examine or develop particular remedy parameters for these sufferers with melasma.”

“We all know that pores and skin tightening is a troublesome activity for a nonablative, nonsurgical gadget,” mentioned Murad Alam, MD, professor and vice-chair of dermatology and chief of the part of cutaneous and aesthetic surgical procedure at Northwestern College, Chicago, who was requested to touch upon the examine.

“The promise is of restricted downtime, lack of scars, and minimal discomfort, however we have not but had a house run. As a consequence, there is a fixed effort to develop new and higher gadgets. This examine is fascinating as a result of it reveals that sure, a brand new and higher gadget may be good, however let’s not overlook the concept of getting a number of gadgets on the identical time. The great factor they’ve proven is that from a security standpoint, utilizing each radiofrequency and ultrasound was tolerable when it comes to security, discomfort, and downtime.”

BTL Aesthetics, the producer, loaned the gadget used within the trial. Chilukuri reported having no different monetary conflicts for this examine. Alam reported having no disclosures.
