Study summary

This randomized, interventional study evaluates the efficacy of Collagendep Pink Beauty, an oral nutritional supplement, in reducing vulvar dryness in women with Genital Lichen Sclerosus (VLS) who are undergoing fat grafting treatment. Lichen sclerosus is a chronic inflammatory condition that leads to tissue hardening, loss of elasticity, and significant symptoms such as itching, pain, and dryness, which severely impact functional and emotional well-being. While fat grafting is a recognized regenerative therapy for stabilizing the disease, this study investigates whether a 4-month course of bioactive collagen peptides and functional ingredients can further improve mucosal hydration and symptom relief compared to fat grafting alone.

Read the detailed description

Lichen sclerosus is a chronic inflammatory disease primarily affecting the ano-genital area, characterized by sclerosis and tissue atrophy. Current medical treatments, such as long-term corticosteroid use, may exacerbate existing tissue atrophy. In recent decades, regenerative therapies like fat grafting (lipofilling) have shown effectiveness in improving symptoms and stabilizing the condition. This study aims to evaluate the synergistic effect of an oral formulation, Collagendep Pink Beauty, which contains hydrolysed collagen peptides (VERISOL®), extracts of Astragalus and Centella asiatica (Astrion™), low molecular weight hyaluronic acid (HyaSource® Vita Mini), and nucleotides (Ribocare®). These ingredients are intended to stimulate endogenous collagen production and exert a trophic action on the vaginal mucosa

Study arms

  • Experimental
    Intervention Group (Fat Grafting + Collagendep)

    Patients in this arm will undergo the standard surgical procedure of autologous fat grafting (lipofilling) for Genital Lichen Sclerosus. Additionally, they will receive oral supplementation with Collagendep Pink Beauty (1 drink stick per day) for a total duration of 4 months (120 days), starting from the day of surgery (T0).

    Procedure: Autologous Fat Grafting (Lipofilling) · Dietary Supplement: Collagendep Pink Beauty

  • Active comparator
    Control Group (Fat Grafting Only)

    Patients in this arm will undergo the standard surgical procedure of autologous fat grafting (lipofilling) for Genital Lichen Sclerosus without any additional oral supplementation.

    Procedure: Autologous Fat Grafting (Lipofilling)

Interventions

  • ProcedureAutologous Fat Grafting (Lipofilling)

    Standard regenerative surgical procedure involving the harvesting, processing, and reinjection of autologous fat into the vulvar tissues affected by Lichen Sclerosus.

  • Dietary supplementCollagendep Pink Beauty

    Oral nutritional supplement containing bioactive collagen peptides (VERISOL®), hyaluronic acid, nucleotides, and herbal extracts (Astrion™). Dosage: 1 stick per day for 120 days.

What researchers measure

Primary outcomes

  1. Reduction in Vulvar Dryness

    Evaluation of the efficacy of Collagendep Pink Beauty in reducing vulvar dryness. This is measured using the "Vaginal Dryness" category of the Visual Analogue Scale (VAS), where 0 represents the complete absence of the symptom and 10 represents the maximum intensity

    Time frame: Baseline (T0), 2 months (T1), 4 months (T2), and 6 months (T3)

Secondary outcomes

  1. Improvement of Mucosal Hydration

    Measured through Trans-Epidermal Water Loss (TEWL) analysis to evaluate skin barrier integrity and mucosal hydration

    Time frame: Baseline (T0) and 4 months (T2)

  2. Improvement in Sexual Function

    Measured using the Female Sexual Function Index (FSFI), which assesses six domains of sexual function through 19 items (score 0-5). Higher scores indicate better sexual function.

    Time frame: Baseline (T0), 2 months (T1), 4 months (T2), and 6 months (T3).

  3. Patient Satisfaction with Treatment

    Assessed with a single question: "How satisfied are you with the effectiveness of the treatment received?", using a 5-point Likert scale (0 = very dissatisfied; 4 = very satisfied)

    Time frame: 6 months (T3)

Other outcomes

  1. Reduction of Clinical Symptoms

    Assessment of the reduction of itching, burning, and pain using the Dermatology Life Quality Index (DLQI). The questionnaire consists of 10 items, each rated on a 4-point Likert scale (0-3). Higher scores indicate a greater impairment of quality of life

    Time frame: Baseline (T0), 2 months (T1), 4 months (T2), and 6 months (T3)
