Primary Outcome Measures :
  1. Number of Participants Reporting Product Tolerability Based on Evaluator Global Assessment Scores [ Time Frame: 14 days after completion of the facial peel procedure ]
    The dermatologist assessed the local tolerance of the post-procedure skin care regimen in context of the expected effects of the procedure for each participant using the scale as below: 0 - Product regimen was well tolerated, 1 - product regimen was not well tolerated. The dermatologist observed on the total set of clinical and participant self-assessment data for each participant. Lower scale value implies that no clinically significant worsening of the expected signs/symptoms of the procedure, no new signs/symptoms manifest during product use. Whereas, higher scale value implies clear, clinically relevant worsening of the severity or frequency of expected signs/symptoms of the procedure and/or any occurrence of new, unexpected signs/symptoms during product use.


Secondary Outcome Measures :
  1. Change From Baseline in Total Score of Dermatologist Assessments [ Time Frame: 14 days after completion of the facial peel procedure ]
    The assessments of Erythema, Dryness, Desquamation and Edema were conducted by a dermatologist on the participant's skin condition at the 5 x 5 cm square area on the volar surface of forearm. The signs were scored on a scale. Erythema on 0-3 where, 0=none-no redness, 1=mild-slight redness, 2=moderate-definite redness, 3=severe-marked redness. Dryness on 0-3 where, 0=none-no dryness, 1=mild-barely perceptible, fine scales to limited areas of test site, 2=moderate-fine scales generalized to all areas of test site, 3=severe-scaling and peeling of skin over all areas of test site. Desquamation on 0-3 where, 0=none-no sign of peeling, 1=mild-barely perceptible scaling, 2=moderate-minimal scaling, 3=severe-moderate scaling. Edema on 0-3 where, 0=none-no edema, 1=mild-barely perceptible edema, 2=moderate-definite edema, 3=severe-pronounced edema. The measure is sum of participant scores, so a total score scale ranges from 0-12, with higher scores indicating increased signs of irritation.

  2. Number of Participants Reporting no/Mild/Moderate/Severe Change From Baseline in Individual Dermatologist Scores for Erythema, Edema, Desquamation and Dryness [ Time Frame: 14 days after completion of the facial peel procedure ]
    The signs/symptoms of participants were scored on a scale of 0 to 3 as below: Erythema: Score from 0=None-No evidence of erythema present, 1=Mild-Slight red coloration, 2=Moderate-Definite redness, 3=Severe-Marked erythema, bright red to dusky dark red in color. Dryness: Score from 0=None-No dryness, 1=Mild-Barely perceptible, fine scales or flakes present to limited areas of the test site, 2=Moderate-Fine scales or flakes generalized to all areas of the test site, 3=Severe -Scaling and peeling of skin over all areas of the test site. Desquamation score from 0=None-No evidence of desquamation/peeling, 1=Mild-Barely perceptible scaling; evident only on scratching, 2=Moderate-Minimal scaling, adherent to the skin, 3=Severe -Moderate scaling, loosely adherent to the skin and easily removable. Edema score from 0=None-No edema present, 1=Mild-Barely perceptible edema present, 2=Moderate-Definite edema present, 3=Severe-Marked/pronounced edema present.

  3. Change From Baseline in Sum of Participant Self-assessment Scores for Redness, Pain, Stinging/Burning, Itching, Tightness and Dryness [ Time Frame: 14 days after completion of the facial peel procedure ]
    The assessments of Pain, Stinging/ Burning, Itching, Tightness, Redness and Dryness were conducted by participants reflective of their skin condition at the 5 x 5 cm square area on the volar surface of the forearm at the time of evaluation. Participants were scored as per signs/symptom: pain, stinging/burning, itching, tightness, redness and dryness on scale of 0 to 3, where 0= none; no sign or symptoms, 1= mild; barely perceptible, 2= moderate; definite signs and symptoms, and 3= severe- marked or pronounced signs or symptoms. This outcome measure is the sum of participant scores, so a total score, i.e. the range is 0-15, with higher scores indicating increased signs or symptoms of irritation.

  4. Change From Baseline in Participant Self-assessment Scores for Redness [ Time Frame: 14 days after completion of the facial peel procedure ]
    The following assessments were conducted by participants reflective of their skin condition at the time of evaluation for redness. Participants were score on a scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Lower scores indicate better results.

  5. Change From Baseline in Participant Self-assessment Scores for Pain [ Time Frame: 14 days after completion of the facial peel procedure ]
    The following assessments were conducted by participants reflective of their skin condition at the time of evaluation for pain. Participants were scored on a scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Lower scores indicate better results.

  6. Change From Baseline in Participant Self-assessment Scores for Itching [ Time Frame: 14 days after completion of the facial peel procedure ]
    The following assessments were conducted by participants reflective of their skin condition at the time of evaluation for itching. Participants were scored on a scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Lower scores indicate better results.

  7. Change From Baseline in Participant Self-assessment Scores for Stinging/Burning [ Time Frame: 14 days after completion of the facial peel procedure ]
    The following assessments were conducted by participants reflective of their skin condition at the time of evaluation for stinging/burning. Participants were scored on a scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Lower scores indicate better results.

  8. Change From Baseline in Participant Self-assessment Scores for Tightness [ Time Frame: 14 days after completion of the facial peel procedure ]
    The following assessments were conducted by participants reflective of their skin condition at the time of evaluation for tightness. Participants were scored on a scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Lower scores indicate better results.

  9. Change From Baseline in Participant Self-assessment Scores for Dryness [ Time Frame: 14 days after completion of the facial peel procedure ]
    The following assessments were conducted by participants reflective of their skin condition at the time of evaluation for dryness. Participants were scored on a scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Lower scores indicate better results.

  10. Change From Baseline in Instrumental Measurement of Barrier Function Using Tewameter [ Time Frame: 14 days after completion of the facial peel procedure ]
    Trans-epidermal water loss (TEWL) measurement was performed by evaporimetry with a Tewameter. Measurements were taken in triplicates on the left cheek (below the cheekbone between the nose and ear). TEWL measurements were taken with the participant lying horizontally, on their back, so that the chimney of the Tewameter probe is aligned vertically. An increase in TEWL values shows damage to the skin barrier function.

  11. Change From Baseline in Instrumental Measurement of Moisturisation Using Corneometer [ Time Frame: 14 days after completion of the facial peel procedure ]
    Measurement of stratum corneum hydration was performed by the electrical capacitance method with a Corneometer. Corneometer measurements were taken in triplicates at the left cheek (below the cheekbone, between the nose and ear) with the participant lying horizontally, on their back. An increase in corneometry values indicates an increase in the hydration status of the skin and vice versa.

  12. Global Self-assessment of Participants [ Time Frame: 14 days after completion of the facial peel procedure ]
    Participants has rated the level of satisfaction with the post-procedure skin care regimen to which they were randomized on a scale of 0 to 3 as follows: 0 (Very satisfied), 1 (Satisfied), 2 (Poorly satisfied), 3 (Not at all satisfied). Lower scores indicate better results.
