Superficial MFU-V and Diluted Calcium Hydroxyapatite for the Improvement of Lower Face Skin Quality and Wrinkles
- Conditions
- Aging
- Interventions
- Device: Ulthera System [Ulthera, Inc.]Device: Merz Radiesse Injectable Implant
- Registration Number
- NCT05469516
- Lead Sponsor
- Cutis Medical Laser Clinics Pte Ltd
- Brief Summary
Aging, genetics and environmental factors contribute to multiple changes on the surface of the skin. These present with pigmentation, volume loss, loss of elasticity and loss of collagen. Altogether, areas of the face becomes "crepey", with resulting rhytids and an obvious appearance of thin and fragile skin. These are typically dermal manifestations of elastin and collagen loss resulting in a collective term of loss of "skin quality".
Current treatments to improve these changes involve the use of skincare, chemical peels, as well as more invasive repeated treatments such as microneedling and laser resurfacing. These commonly require repeated treatments and several days of downtime. More recently, treatment with a hybrid preparation of high and low-molecular weight complexes that are thermally cross-linked (Profhilo) has been suggested to stimulate collagen and elastin formation, thereby resulting in improvement in skin quality.

These commonly require repeated treatments and several days of downtime. More recently, treatment with a hybrid preparation of high and low-molecular weight complexes that are thermally cross-linked (Profhilo) has been suggested to stimulate collagen and elastin formation, thereby resulting in improvement in skin quality However, the evidence for this remains limited. Microfocused Ultrasound with Visualization (MFU-V) and Calcium hydroxylapatite (CaHA) have each been unequivocally proven to stimulate neocollagenesis and elastogenesis, leading to improvement in skin laxity. A recent study of a single-treatment single-depth of superficial MFU-V was found to result in aesthetic improvement of the accordion lines. In addition, there is recent evidence that CaHA in a hyperdiluted form can stimulate collagen and elastin formation. Indeed, this group of investigators has recently published the effectiveness of a single treatment of a combination MFU-V and diluted CaHA for improving brachial skin laxity. Arguably, there is a need to publish additional studies on these interventions for improving firmness and skin quality. In addition, there may be a theoretical cumulative benefit in using both treatments for improving skin quality, although the effectiveness of this combination has not been demonstrated.
With this background, the main rationale of performing this study is to demonstrate the safety and efficacy of a multimodality approach with a single treatment of superficial MFU-V and diluted CaHA for improvement of skin quality in Asian and Caucasian patients. The investigators selected Lower Face as the target area for the following reasons: 1) The Lower Face manifests the greatest with thinning, fine wrinkling and general fragility of the skin, 2) Volumization is not always aesthetically pleasing in this area but firmness of the skin is, 3) This area is an established treatment area for MFU-V, CaHA but not with other treatment options such as Profhilo.

Group Intervention Description Ultherapy and Radiesse Ulthera System [Ulthera, Inc.] Delivered to the lower face areas as drawn using a single transducer with a focal depth of 1.5mm (following a previously published paper (Lowe, 2021) but with extension of the lower treatment area to the two-ruler width (Ulthera marking ruler) as treatment zones. Application will be delivered through a cross-hatching technique. Immediately following MFU-V or up to a week after, diluted CaHA will be administered following the Global Consensus Guidelines published in 2018 by de Almeida et al as follows 1) 1 syringe or 1.5ml of CaHA diluted 1:1 with saline for a total of 3ml of solution or 1.5 diluted CaHA per side will be injected in the subdermal plane with a cannula using a retrograde fanning technique.

- Primary Outcome Measures
Name Time Method Change in Skin Quality 1 Month, 3 Months and 6 Months post intervention Pre and post treatment comparison of change in skin quality. These will be measured using Quantificare LifeViz Micro, an established tool to objectively measure and validate treatment results of skin quality which will allow to accurately quantify changes with specific measurement tools.
Change in Wrinkle Reduction 1 Month, 3 Months and 6 Months post intervention Pre and post treatment comparison of change in dimensions of fine lines (volume/depth/length). These will be measured using Quantificare LifeViz Micro, an established tool to objectively measure and validate treatment results of lines, which will allow to accurately quantify changes with specific measurement tools.
- Secondary Outcome Measures
Name Time Method Visual Aesthetic Improvement Score 1 Month, 3 Months and 6 Months post intervention Pre and post treatment comparison of Visual Aesthetic Improvement Score of standardized patient photographs by study investigators. Both VISIA Imaging photographs and standard photographs will be used.
