A Study to Assess the Effects of an Oral Dietary Supplement on Overall Facial Appearance Among Healthy Adult Women With Existing Skin Damage From Sun Exposure

IGA of overall facial appearance was measured using a numerical severity rating scale of 0 to 9 using 1/2 points, where 0 to less than or equal to (<=) 3 signifies Mild; greater than (>) 3 to <=6 signifies Moderate and >6 to <=9 signifies Severe.

IPRC assessment was performed in accordance with the Canfield procedures and rated the improvement relative to Baseline. The investigators used an improvement scale that ranged from -3 to 3 (where -3 = Definite worsening, -2 = Moderate worsening, -1 = Slight worsening, 0 = No change, 1 = Slight improvement, 2 = Moderate improvement, 3 = Definite improvement).

IGA of overall facial appearance was measured using a numerical severity rating scale of 0 to 9 using 1/2 points, where 0 to less than or equal to (<=) 3 signifies Mild; greater than (>) 3 to <=6 signifies Moderate and >6 to <=9 signifies Severe.

Investigator performed the assessment of face (Fine lines/wrinkles (L/W) of the periocular area (A), Fine lines/wrinkles of the perioral area, dark circles (dc) or "bags" under the eye, mottled hyperpigmentation (MH), sallowness/yellowing, roughness/texture) using a numerical severity rating scale of 0 to 9, where 0 to less than or equal to (<=) 3 signifies Mild; greater than (>) 3 to <=6 signifies Moderate and >6 to <=9 signifies Severe.

Investigator performed the assessment of decolletage and back of hands (crepyness, mottled hyperpigmentation [MH]) using a numerical severity rating scale of 0 to 9 using 1/2 points, where 0 to less than or equal to (<=) 3 signifies Mild; greater than (>) 3 to <=6 signifies Moderate and >6 to <=9 signifies Severe.

Participants performed the assessment of face (overall facial (OA) appearance, fine lines and wrinkles (L/W) present in the eye area, upper lip, or cheek areas, under eye dark circles (dc) or bags, discoloration [uneven, patchy, blotchy areas of light and dark, age spots, liver spots], complexion/glow [bright radiant appearance] and smoothness) at Baseline using a 10-point numerical scale, and at Week 12, 24 using a 7-point improvement scale. At Baseline, participants rated the facial parameters using a 10-point scale ranging from 1 (Not noticeable) to 10 (Very noticeable). At Week 12 and 24, assessment was performed relative to Baseline using an improvement scale that ranged from -3 to 3 (where -3 = Definite worsening, -2 = Moderate worsening, -1 = Slight worsening, 0 = No change, 1 = Slight improvement, 2 = Moderate improvement, 3 = Definite improvement).

Participants performed the assessment of decolletage (decolletage overall, decolletage-wrinkling/crinkling (W/C), decolletage-discoloration (DD) and back of hands (back of hands overall, back of hands (BOH) - Fine lines/wrinkles (L/W), back of hands - discoloration) and Body - Dryness (BD) Overall at baseline using a 10-point numerical scale, and at Week 12, 24 using a 7-point improvement scale. At Baseline, participants rated the Decolletage, Back of Hands and Body parameters using a 10-point scale ranging from 1 (Not noticeable) to 10 (Very noticeable). At Week 12 and 24, assessment was performed relative to Baseline using an improvement scale that ranged from -3 to 3 (where -3 = Definite worsening, -2 = Moderate worsening, -1 = Slight worsening, 0 = No change, 1 = Slight improvement, 2 = Moderate improvement, 3 = Definite improvement).

DermaLab Combo Skin Lab with an 8-pin probe was used to measure hydration (corneometry). Hydration measurements of the left cheek, left inner arm, and left outer arm were taken (up to 3 measurement).

Trans-epidermal water loss (TEWL) measurements were done using DermaLab Combo SkinLab with a cylindrical diffusion chamber (10 mm [millimeter] diameter) containing 2 combined humidity/temperature sensors to determine the amount of water vapor that moves across the stratum corneum. TEWL measurements were taken on the left cheek and the left inner and outer arm (up to 3 measurement).

Skin thickness was measured using the DUB Cutis (taberna pro medicum), a high frequency and high resolution diagnostic ultrasound system. Measurements were taken on the left cheek, and the left inner and outer arm (up to 3 measurement).

Skin density was measured using the DUB Cutis (taberna pro medicum), a high frequency and high resolution diagnostic ultrasound system with 100 percent (%) calibration mode. Measurements were taken on the left cheek, and the left inner and outer arm (up to 3 measurement).
