EXAMPLE 1
A Clinical Study to Evaluate the Benefit of a Dietary Supplement on Skin When Consumed by Adults With Facial Acne Conditions

A single-center cosmetic clinical trial was conducted to assess the efficacy of a dietary supplement when taken over the course of 12 weeks by women and men in good general health, having Fitzpatrick skin type I-VI and having facial acne at one of the following severity levels:

    • (i) Mild to moderate facial acne (score of 2-3 according to the FDA IGA of Acne Severity) with at least 3 inflammatory lesions and at least 5 non-inflammatory lesions on the face at baseline OR
    • (ii) Severe facial acne (score of 4 according to the FDA IGA of Acne Severity) with at least 5inflammatory lesions and at least 5 non-inflammatory lesions on the face at baseline (at least n=3 and maximum of n=7 subjects).


Fifty-one subjects were recruited with 39 subjects (mean age=31.5±7.7 years, range=19-48) completing the study as outlined in FIG. 1, with daily treatment with four capsules, each containing the ingredients listed in FIG. 2. Subject demographics were female (67%), White/Caucasian (41%, 6:10 M: F ratio), Black (41%, 5:11 M: F ratio), and Asian (13%, 1:3 M: F ratio).


Assessment Protocol
FDA IGA of Acne Severity

At baseline and weeks 4, 8, and 12, an expert grader evaluates each subject's global face using the FDA IGA scale, with half scores used as necessary.


Acne Lesion Counts

Acne lesion counts are performed at baseline and weeks 4, 8, and 12. A clinical evaluator counts and records the number of papules, pustules, open comedones, closed comedones, and cysts/nodules on each subject's face. Papules, pustules, and cysts/nodules are classified as inflammatory acne lesions while open and closed comedones are classified as non-inflammatory lesions.


Acne lesion and macule counts are assessed separately for each of the following facial locations/quadrants: forehead, left cheek (including left side of nose), chin (including the area above the upper lip), and right cheek (including right side of nose). Lesions under the jawline or along the hairline (including eyebrows) will not be included in the counts.


Clinical Grading of Efficacy Parameters

Clinical grading of efficacy parameters is performed at baseline and weeks 4, 8, and 12. The efficacy parameters are assessed by the expert grader at the indicated locations using a modified Griffiths 10-point scale according to the following numerical definitions. Half-point scores may be used as necessary to describe the skin condition more accurately.

    • 0=none (best possible condition)
    • 1 to 3=mild
    • 4 to 6=moderate
    • 7 to 9=severe (worst possible condition)


The following parameters are evaluated using the indicated scale anchors:

Bioinstrumentation Measurements

Corneometer Measurements: Corneometer measurements are performed at baseline and weeks 4, 8, and 12. Triplicate Corneometer measurements are taken on the center of each subject's right or left cheek (at the intersection of lines extending up from the corner of the mouth and horizontally across the bottom of the nose) according to a predetermined randomization. The Corneometer CM 825 (Courage+Khazaka electronic GmbH, Koln,


Germany), in conjunction with product treatment, is used to measure product hydration effects on the skin surface. The Corneometer measures moisture content in the stratum corneum by an electrical capacitance method. The measurement has no units but is proportional to the dielectric constant of the surface layers of the skin and increases as the skin becomes more hydrated. The readings are directly related to the skin's electrical capacitance (picofarads).


Tewameter Measurements: Tewameter measurements are performed at baseline and weeks 4, 8, and 12. Duplicate Tewameter measurements are taken on the center of each subject's right or left cheek (at the intersection of lines extending up from the corner of the mouth and horizontally across the bottom of the nose) on the opposite side from where Corneometer measurements were taken. The Tewameter TM300 or Tewameter Triple TM330T (Courage+Khazaka electronic GmbH, Koln, Germany) measures the passive transfer of water through the stratum corneum (transepidermal water loss (TEWL)). The measurement of this water evaporation is based on the diffusion principle in an open chamber and the density gradient is measured indirectly by two pairs of sensors located inside the hollow cylindrical probe. Data are analyzed by a microprocessor and reported in g/m2/h. A decrease in TEWL values reflects an improvement in the barrier properties of the skin.


Sebumeter Measurements: Sebumeter measurements are performed at baseline and weeks 4, 8, and 12. Duplicate Sebumeter measurements are taken on non-lesion, adjacent, nonoverlapping areas of each subject's forehead, with the location marked on a facial diagram. The Sebumeter SM 815 (Courage+Khazaka electronic GmbH, Koln, Germany) measures sebum quantity on the skin using a photometric method. This method is independent of moisture. The measurement is the transmission of light through sebutape, a synthetic material that becomes transparent upon contact with sebum. A microprocessor in the Sebumeter calculates the amount (μg sebum/cm2) on the skin surface based on the transparency of the sebutape.


Digital Imaging Procedures

VISIA-CR Imaging Procedures: VISIA-CR imaging procedures are performed at baseline and weeks 4, 8, and 12. Digital images are taken of each subject's face (left, front, and right views) (3 total) using the VISIA-CR photo station (Canfield Imaging Systems, Fairfield, New Jersey) with a Canon R5 digital SLR camera (Canon Incorporated, Tokyo, Japan) and LED flash illumination under the following lighting conditions:

    • Standard clinical: visible (bright)
    • Cross-polarized
    • Parallel polarized

Microbiome Sampling Procedures

Subjects participate in microbiome sampling procedures at baseline and week 12. Each subject will have 2 microbiome sampling test sites: 1 on the forehead and 1 on the left or right cheek, as determined by the grader or designee. Facial diagrams for each subject are marked for swab sites at baseline to ensure the samples are taken from the same locations at all time points. Surface skin microflora samples are collected from each subject's swab test site (approximately 4 cm2 area of the skin) using a non-invasive swab technique.


Self-Assessment Questionnaires

Subjects complete a self-assessment questionnaire at baseline and weeks 4, 8, and 12.


Results

Analysis of Self-Assessment Questionnaires. Scores range from 1-4, where 1 is most favorable and 4 is most unfavorable.

Conclusions

Hydration and sebumeter measurements using the template of FIG. 6 improved significantly compared to baseline over the 12-week treatment period (FIG. 3).


87% of participants rated their skin clearer and 67%-85% of participants rated their skin quality parameters improving during the duration of the study (FIGS. 4A, 4B and 5).


The results show improvements in acne and skin parameters in adults over the course of 12 weeks (FIGS. 7A-7F).
