About this study

The chromophore of the 1927 nm diode laser is mainly water, which can be used for skin rejuvenation. This study intends to use the Solta CLEAR+BRILLIANT Laser System, featuring a 1927 nm diode laser with 5 mJ energy, a treatment spot of 140 μm, a treatment depth of 170 μm, and a treatment coverage of approximately 5% per energy level after four rounds of treatment using the patented Intelligent Optical Tracking® System (IOTs). The purpose of this research project is to investigate the treatment design, therapeutic effects and safety of the 1927 nm laser for the rejuvenation of the skin around the eyes. This is an open-label, single-center clinical trial. Participants will be randomized into treatment groups, including Group A (treatment interval of 2 weeks) or Group B (treatment interval of 4 weeks).

Primary outcomes

  1. Change From Baseline in Texture Score at Visit 4 (End-of-study Session)

    Time frame: Group A: baseline and week 8; Group B: baseline and week 12

    The texture score is a parameter measured by the Antera 3D system, calculated based on average roughness (Ra [μm]). Ra roughness, or average roughness, is a standard metric used to describe surface smoothness. It represents the average height of microscopic peaks and valleys on the skin surface. The Ra [μm] values range from 0 to infinity.

    To interpret the texture score, skin surface roughness is categorized into five intervals: Mild: 0-25, Moderate: 25-50, Advanced: 50-75, Severe: 75-100, Very Severe: >100. Higher scores indicate poorer skin texture. The overall texture score ranges from 0 to infinity.

    Change from baseline in texture score at Visit 4 = texture score at Visit 4 - texture score at baseline

Secondary outcomes

  1. Change From Baseline in Color Measurements (L*) at Visit 4 (End-of-study Session)

    Time frame: Group A: baseline and week 8; Group B: baseline and week 12

    In the CIELAB color space, the L* value represents the lightness of a color, indicating how light or dark it appears. The scale ranges from 0 (black) to 100 (white), providing a standardized measure of brightness that aligns with human visual perception. This metric is particularly useful in assessing skin tone. The average L* value within a region of interest was calculated at each visit.

    Change from baseline in L* at Visit 4 = L* at Visit 4 - L* at baseline

  2. Change From Baseline in Pigmentation Score at Visit 4 (End-of-study Session)

    Time frame: Group A: baseline and week 8; Group B: baseline and week 12

    The pigmentation score is a parameter measured by the Antera 3D system, calculated based on the variation (arbitrary units) and average level (arbitrary units). Variation (arbitrary units) indicates mean value within the region of interest of all deviations from the pigmentation average level in absolute value. Average level (arbitrary units) indicates the average concentration of pigmentation in the region of interest. To interpret the pigmentation score, skin pigmentation is categorized into five intervals: Mild: 0-25, Moderate: 25-50, Advanced: 50-75, Severe: 75-100, Very Severe: >100. Higher scores indicate poorer pigmentation conditions. The overall pigmentation score ranges from 0 to infinity.

    Change from baseline in pigmentation score at Visit 4 = pigmentation score at Visit 4 - pigmentation score at baseline

  3. Change From Baseline in Pores' Index at Visit 4 (End-of-study Session)

    Time frame: Group A: baseline and week 8; Group B: baseline and week 12

    The pores' index is an overall score representing skin porosity within the selected region of interest. It incorporates pore depth, size, and density-condensed into a single parameter. This index is particularly useful for the global evaluation of porosity reduction in before-and-after comparisons.

    Formula: Index = (V / S) × 1000 V = total volume of pores in the selected area (mm³) S = selected area (mm²)

    Change from baseline in pores' index at Visit 4 = pores' index at Visit 4-pores' indexe at baseline

  4. Change From Baseline in Wrinkles' Score at Visit 4 (End-of-study Session)

    Time frame: Group A: baseline and week 8; Group B: baseline and week 12

    The wrinkle score is a parameter measured by the Antera 3D system, calculated based on the indentation index (μm). The indentation index (μm) represents the average depth of all points or dents below the surface level. The indentation index (μm) values range from 0 to infinity.

    To interpret the wrinkle score, skin damage is categorized into five intervals: Mild: 0-25, Moderate: 25-50, Advanced: 50-75, Severe: 75-100, Very Severe: >100. Higher scores indicate more severe wrinkle conditions. The overall wrinkle score ranges from 0 to infinity.

  5. Change From Baseline in Physician Assessment of Global Aesthetic Improvement Score (GAIS), at Visit 4 (End-of-study Session)

    Time frame: Group A: baseline and week 8; Group B: baseline and week 12

It ranges as follows: 5 - Very Much Improved, 4 - Much Improved, 3 - Improved, 2 - No Change, 1 - Worse Physician Assessment of GAIS refers to the GAIS score evaluated by the physician.
