What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Skin clinical scores

    Dermatologists use a 10-point scale (0-9) and Volume 2 of the Atlas of Skin Aging for visual/tactile assessment. (includes elasticity, firmness, crow's feet, under-eye wrinkles, facial sagging, skin tone radiance, moisturization)

    Measured: Day0、Day28、Day56、Day84

Secondary outcomes (8)
  1. Self-assessment by subjects

    Subjects self-rated using a 10-point scale (0-9). (includes skin beauty, visibility of wrinkles, skin tone evenness, radiance, firmness)

    Measured: Day0、Day28、Day56、Day84

  2. Dermal echo parameters

    Using Dermcup® high-frequency B-mode ultrasound scanning (25 MHz probe) to obtain dermal echo parameters

    Measured: Day0、Day28、Day56、Day84

  3. Color and clarity of spots

    Dermatologists use Pantone color cards to score the color and clarity of spots

    Measured: Day0、Day28、Day56、Day84

  4. Wrinkles, skin tone uniformity, and spots

    COSderma Photobench photography + Newtone software analysis to obtain information on wrinkles, skin tone uniformity, and spots

    Measured: Day0、Day28、Day56、Day84

  5. Stratum corneum moisture index

    Corneometer® CM825 capacitance measurement method to obtain Stratum corneum moisture index

    Measured: Day0、Day28、Day56、Day84

  6. Biomechanical properties of the skin

    DTM310 Diastron® torque meter obtains information on skin biomechanical properties

    Measured: Day0、Day28、Day56、Day84

  7. Freckle removal effect

    Siascope V® spectrophotometric intradermal analysis obtains information on freckle removal effects

    Measured: Day0、Day28、Day56、Day84

  8. Self-assessment of cosmetic quality and efficacy

    By distributing 12 questionnaires to the subjects, self-assessment information on the quality and effectiveness of cosmetics was obtained. A four-point Likert scale was used (Agree, Somewhat Agree, Somewhat Disagree, Disagree), and the questionnaire content included: 1. Skin feels better; 2. Skin becomes fairer; 3. Pigmentation on the skin lightens or decreases; 4. Skin becomes radiant; 5. Skin becomes more elastic; 6. Skin is firmer than before; 7. Skin wrinkles and fine lines improve; 8. Skin becomes moisturized/hydrated; 9. Skin's oil-water balance is better; 10. Skin looks rejuvenated, full of energy; 11. Sleep improves after consumption; 12. Memory improves after consumption.

What are the possible benefits and risks?

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Skin clinical scores (time frame: Day0、Day28、Day56、Day84). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
