Applications of the new Aeva-HE™ imaging system: Its link with the visual evaluation of facial wrinkles and its potential in screening tensile products

OBJECTIVES

To evaluate, in vivo, a recently developed imaging system (Aeva-HE™), based on fringe projection methodology: (i) its correlation with expert's assessments and real age of 85 French Caucasian women and (ii) its potential, as a screening tool, in rapidly selecting prototypes of tensile cosmetic products.

MATERIALS AND METHODS

First, the bare faces of 85 differently aged French/Caucasian women were photographed under standard conditions and further analyzed by the Aeva-HE™ device. An expert aesthetician graded the severity of wrinkling on a fixed scale, helped by the use of a dedicated Skin Aging Atlas. A panel of 15 judges performed the same task on full-face standard photographs. The Aeva-HE™ software yielded various wrinkle's parameters (density, volume, mean depth, etc.) on different facial locations, according to age-groups. Second, seven women, balanced in age and wrinkling severity, were recruited in a separate study. These women applied at Day 1 a prototype of the tensile product and at Day 2, they applied another prototype of the tensile product. The whole faces (before and after products application) of the seven studied women were captured and analyzed by the Aeva-HE™ system.

RESULTS

The density of wrinkles was significantly highly correlated with the aesthetician scores and, unsurprisingly, with age. Some parameters (volume, depths) of different wrinkles (glabellar, crow's feet, cheeks) were quantified, showing different absolute values and of statistically different progressions with age. The amplitudes of the rapid effects brought by the two prototypes of tensile products were clearly differentiated.

CONCLUSION

The recently developed device Aeva-HE™ is an efficient system for rapidly establishing a faithful and precise status of facial wrinkles, in vivo and seems like a precious tool in the rapid screening of tensile products, possibly performed on a rather limited number of subjects.

Analgesic electrical currents associated with carboxytherapy in women with cellulite: A randomized controlled trial

BACKGROUND

Pain is considered the main limiting factor in carboxytherapy. Electroanalgesia has gained recognition in the field of dermatology and to date, only transcutaneous electrical nerve stimulation (TENS) has proved to be effective at reducing pain associated with carboxytherapy; however, the effect of medium frequency currents has yet to be investigated.

AIMS

Compare the effects of TENS, interferential current (IFC), and Aussie current on pain intensity associated with carboxytherapy and sensory comfort in the treatment of cellulite.

PATIENTS/METHODS

Seventy-five women aged 18-49 years with moderate and/or severe gluteal cellulite were randomized into three groups: TENS (n = 25), IFC (n = 25), and Aussie current (n = 25), which underwent three sessions of carboxytherapy associated with an electrical current. Current amplitude was adjusted after each puncture, according to the maximum tolerance reported by participants, below the motor threshold. Pain intensity was measured using a numeric rating scale (0-10) and sensory comfort with the visual analogue scale (0-10).

RESULTS

There was no significant intergroup difference in pain intensity (p > 0.05) and sensory comfort (p = 0.502) during the application of carboxytherapy throughout the three treatment sessions.

CONCLUSION

TENS, IFC, and Aussie currents showed no difference in pain intensity reduction and no current was found to be more comfortable.

Changes in Skin Microcirculation Resulting from Vibration Therapy in Women with Cellulite

Background: Cellulite is a cosmetic defect that affects over 80% of post-pubertal women. One of its pathomechanisms involves microvascular dysfunction. It has been suggested that vibration is a physical stimulus that may improve circulation in the skin and muscles. The aim of this study was to evaluate the effect of local vibration on cutaneous microcirculation and on eliminating the symptoms of cellulite in women. Methods: A total of 57 healthy women with at least grade 1 cellulite were recruited and divided into four groups differing by treatment time (30′ or 60′) and position (sitting or lying) during the vibration treatments. Participants took part in 15 vibrotherapy sessions. Body composition, selected circumferences, cellulite grade, and thermographic images of buttocks and thighs were recorded. Results: Significant changes in skin temperature were observed in both studied areas after the first and last treatments in each group. A significant decrease in cellulite grade was observed after a series of treatments. The strongest effects were observed for the sitting position with a treatment time of 60 min. Conclusion: Vibration treatment improves microcirculation in cellulite-affected areas. Over time, no adaptation was observed, and subsequent treatments maintained the beneficial effects. Extending the treatment time increased its influence on the microcirculation in the skin.

Effect of combined compression-vibration therapy using non-invasive Beautylizer Therapy Cosmospheres V on the subcutaneous tissue morphology in women with gynoid lipodystrophy (pilot study)

BACKGROUND

Gynoid lipodystrophy is one of the most common cosmetical problems in women.

AIMS

The study aims to examine the pathomorphology and histology of subcutaneous tissue in women with gynoid lipodystrophy exposed to local compression/vibration therapy using a non-invasive Beautylizer Therapy Cosmospheres V medical device.

METHODS

The study enrolled 25 virtually healthy women aged 25 to 45 years with gynoid lipodystrophy grades I and II. The women included in the study completed a 10-session month-long therapeutic course with a non-invasive Beautylizer Therapy Cosmospheres V medical device. Bioptic punch-size samples were taken from the gluteal region prior to and following the 10-session therapy course with the device.

RESULTS

After completing a 10-session treatment course, a decrease in the mean adipocyte area from 123.08 ± 13.60 μm to 67.14 ± 4.20 μm was observed in punch bioptic samples of subcutaneous fat tissues of women with gynoid lipodystrophy as compared to the pre-treatment indices.

CONCLUSION

Thus, local application of 10-session therapy with a non-invasive Beautylizer Therapy Cosmospheres V medical device in women with gynoid lipodystrophy demonstrated a positive effect on the histological structure of the hypodermis.

Effect of local vibrotherapy in sitting or lying position in two time protocols on the cellulite grade and change of body circumferences in women with cellulite

BACKGROUND

Vibrotherapy is becoming a new tool which can help to improve aesthetic appearance. One of its basic uses in cosmetology is eliminating cellulite changes.

AIM

The aim of the study was to analyze the effect of a 3-week series of local vibrotherapy in two positions and in two time protocols on selected body circumferences, WHR, WHtR and BAI, and the grade of cellulite.

PATIENTS AND METHODS

Volunteers underwent vibration treatments in a lying or sitting position for 30 or 60 minutes a day, for 3 weeks. Waist, hip, thigh and calf circumferences were measured before and after the first, and before and after the last treatment. The WHR, WHtR and BAI indicators were calculated. The grade of cellulite was assessed with use of the Nürnberger-Müller scale. A multivariate analysis of variance was performed to assess the impact of individual parameters.

RESULTS

After a series of treatments, a significant decrease in the grade of cellulite was noted, regardless of the treatment time or position. The circumferences of the thighs and hips didn't change. Both, the first and the last treatment allowed for change the calf circumference. The applied series of treatments allowed for lower the waist circumference also for change the WHR and WHtR indicators.

CONCLUSION

A series of vibration interventions reduced cellulite symptoms without affecting the hip and thigh circumferences. The treatment positions can be adjusted to the individual needs of the client and time of single treatment can be minimized to 30 min a day.
