About this study

The scope of this clinical trial is to evaluate and confirm thereshaping effect of the face with Definisse Threads double needle and Definisse threads free floating insertion, at day 30. 6 clinical follow up visit will be performed to evaluate the modification of skin surface characteristics, the reshaping effect of the face, the subject's satisfaction at each visit, the presence/absence of the threads after the implantation and the global pain perception during the implant procedure..

Treatment and study plan

Definisse threads free floating and definisse threads double needle

Device

Definisse threads are two class III medical devices, for evaluate the performance of the reshaping effect of the face at day 30

Primary outcomes

  1. Volume of midface and lower face with Definisse threads double needle and Definisse threads free floating insertion at day 30

    Time frame: up to 30 days of treatment

    The primary objective of this clinical investigation is to evaluate the reshaping effect of the face with Definisse™ thread double needle and Definisse™ thread free floating insertion, at Day 30, through 3D photos and 2D photos, through VECTRA®H2

Secondary outcomes

  1. reshaping effect between baseline and T15d, T4m, T8m, T12m.

    Time frame: up to 15 days, 4 months, 8 months and 12 monts of tratment

    To evaluate the reshaping effect of the face with Definisse™ threads between baseline and day 15, 4 months, 8 months, 12 months with GAIS (Global Aesthetic Improvement Scale; 5-item scale, where 1 = exceptional improvement, 2 = very improved, 3 = improved, 4 = unaltered, 5 = worsened.))

  2. To evaluate the modification of skin surface characteristics at 30 days, 4 months, 8 months and 12 monts from baseline

    Time frame: up to 30 days, 4 months, 8 months and 12 monts of tratment

    Modification of skin surface characteristics in terms of wrinkles, pores and texture, that will be evaluated and quantified at day 30d, 4 months, 8 months, 12 months from baseline through ANTERA 3D.

  3. to evaluate the subject's satisfaction at each visit (1 day, 15 days, 30 days, 4 months, 8 months and 12 monts)

    Time frame: up to 1 day, 15 days, 30 days, 4 months, 8 monts and 12 months of treatment

    Subject's satisfaction self-assessment on the reshaping effect according to the Global Aesthetic Improvement Scale (GAIS: 5-item scale, where 1 = exceptional improvement, 2 = very improved, 3 = improved, 4 = unaltered, 5 = worsened.) at each visit (1 day, 15 days, 30 days, 4 months, 8 months and 12 monts).

  4. To assess the clinical evaluation of reshaping effect of the total, middle and lower face comparing baseline to T15d, T30d, T4m, T8m, T12m by the non-treating investigators

    Time frame: up to 15 days, 30 days, 4 months,8 months, 12 months of treatment

    Aesthetic changes of the total, middle and lower face according to the Global Aesthetic Improvement Scale (GAIS: 5-item scale, where 1 = exceptional improvement, 2 = very improved, 3 = improved, 4 = unaltered, 5 = worsened) by the non-treating investigators (one plastic surgeon and one dermatologist) as clinical evaluation of reshaping effect, comparing baseline to T15d, T30d, T4m, T8m, T12m, by evaluating the 2D photos collected by VECTRA®H2

  5. To evaluate the presence/absence of the threads after the implantation at T30d, T4m, T8m, T12m

    Time frame: up to 30 days, 4 months, 8 months, 12 months of treatment

    Presence/absence of the thread in the implant area after 30 days, 4 months, 8 months and 12 monts from the treatment with an ultrasound evaluation.

  6. To evaluate the global pain perception during the implant procedure at T1d and T15d.

    Time frame: up to 1 and 15 days of treatment

    Global pain perception during the implant procedure at 1 day and at the first follow-up visit (15 days) by a numeric pain scale (NRS: from "0" (No pain) to "10" (worst possible pain)).

  7. To evaluate the subject's self-esteem at each visit (1 day, 15 days, 30 days, 4 months, 8 months and 12 monts) T30d, T4m, T8m, T12m).

    Time frame: up to 1 day, 15 ddays, 30 days, 4 months, 8 month, 12 months of treatment

    Subject's self-esteem by the Rosenberg Self-Esteem Scale at each visit ( This scale is a widely used self-report instrument for evaluating individual self-esteem. The scale ranges from 0 to 30. Scores between 15 and 25 are within normal range; scores below 15 suggest low self-esteem.)(1 day, 15 days, 30 days, 4 months, 8 months and 12 monts)
