Arms and Interventions

Arm	Intervention/treatment
Experimental: Group 1 (Test Product); Participants will apply test product (approximately 0.6-1 grams (g)) to full face topically twice daily (morning and evening) after cleansing. All participants will be instructed to continue using the facial cleanser twice-daily during the morning and evening and to apply the sunscreen in the morning (after application of test product) and at lunchtime.	Other: Cream (Test product); Moisturizing cream with SPF (Sun protecting factor) 20; Other: Cleanser (Reference Product); Moisturizing facial cleanser; Other: Sunscreen (Reference Product); SPF 50 sunscreen
Group 2 (No Treatment); Participants will wet face with water and work a small amount of facial cleanser (approximately 0.6-1 g) into lather. Participants will massage topically onto wet skin and rinse with water twice daily (morning and evening). After cleansing, participants will apply a pea-sized quantity (approximately 0.6-1 g) of the sunscreen in the morning and at lunchtime.	Other: Cleanser (Reference Product); Moisturizing facial cleanser; Other: Sunscreen (Reference Product); SPF 50 sunscreen

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Evaluator (Dermatologist) Global Assessment (EGA) Score for Well Tolerance of Product 14 Days Post-Procedure [ 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 below: 0 - Product regimen was well tolerated (No clinically significant worsening of the expected signs/symptoms of the procedure. No new signs/symptoms manifest during product use) and 1 - Product regimen was not well tolerated (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). The Dermatologist drawn assessment on the total set of clinical and participant self-assessment data for each participant.

Secondary Outcome Measures :

1. Change From Baseline in Total Score of Dermatologist Assessment Score [ Time Frame: At baseline (60 minutes post procedure but prior to any test product application), 180 minutes, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure ]
   Participants scored for all domains of Dermatologist Assessment Score using scale of 0 to 3. Erythema (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), Dryness (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 & peeling of skin over all areas of the test site), Desquamation (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 & easily removable), Edema (0=None-No edema present, 1=Mild-Barely perceptible edema present, 2=Moderate-Definite edema present, 3=Severe Marked/pronounced edema present). Total score as 0 to 12, higher scores represent less local tolerance.
2. Change From Baseline in Individual Dermatologist Assessment Scores of Erythema, Dryness, Desquamation and Edema [ Time Frame: At baseline (60 minutes. post procedure but prior to any test product application) and 180 minutes, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure ]
   Participants scored for all domains of Dermatologist Assessment Score using scale of 0 to 3. Erythema (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), Dryness (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 & peeling of skin over all areas of the test site), Desquamation (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 & easily removable), Edema (0=None-No edema present, 1=Mild-Barely perceptible edema present, 2=Moderate-Definite edema present, 3=Severe Marked/pronounced edema present). Higher scores represent less local tolerance.
3. Change From Baseline in Total Score of Participant Self-Assessment Scores [ Time Frame: At baseline (60 minutes. post procedure but prior to any test product application) and 180 minutes, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure ]
   Participant Self-Assessment was conducted by participants reflective of their skin condition at the time of evaluation. Participants scored following signs/symptom: pain, stinging/burning, itching, tightness, redness and dryness on scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Total score ranges as 0 to 18, higher score represents less tolerance to product applied.
4. Change From Baseline in Individual Participant Self-Assessment Scores for Pain, Stinging/Burning, Itching, Tightness, Redness and Dryness [ Time Frame: At baseline (60 minutes. post procedure but prior to any test product application) and 180 minutes, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure ]
   Participant Self-Assessment was conducted by participants reflective of their skin condition at the time of evaluation. Participants scored following signs/symptom: pain, stinging/burning, itching, tightness, redness and dryness on scale of 0 to 3. (0= None, 1= Mild, 2= Moderate, and 3= Severe). Higher score represents less tolerance to product applied.
5. Change From Baseline in Trans-epidermal Water Loss (TEWL) [ Time Frame: At baseline (60 mins. post procedure but prior to any test product application) and 180 mins, 360 mins, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure ]
   Trans-epidermal water loss (TEWL) measurement was performed by evaporimetry with a Tewameter to assess skin barrier function. Measurements was done in triplicate on the left cheek (below the cheekbone between the nose and ear). TEWL measurements was performed the participant lying horizontally, on their back, so that the chimney of the Tewameter probe was aligned vertically.
6. Change From Baseline in Corneometer Measurements [ Time Frame: At baseline (60 mins. post procedure but prior to any test product application) and 180 mins, 360 mins, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure ]
   Corneometry was used to measure moisture content of stratum corneum using corneometer. The corneometer probe was placed in contact with the skin of the participant's test site for 1-2 s per measurement. The corneometer measurements were performed in triplicate at the left cheek (below the cheekbone, between the nose and ear) with the participant lying horizontally, on their back. Corneometer values were measured at 180 mins, 360 mins, 1 day, 2 days, 3 days, 7 days and 14 days after completion of the facial peel procedure to evaluate the impact of twice-daily application of the investigational products on skin moisturization compared to the use of no test product. An increase in Corneometer values corresponds to skin-moisturizing effect.

Other Outcome Measures:

1. Number of Participants With Global Self-Assessment of Satisfaction Score [ Time Frame: 14 days after completion of the facial peel procedure ]
   Participants rated the level of satisfaction with the post-procedure skin care regimen to which they were randomized using scale as follows: 0 (Very satisfied), 1 (Satisfied), 2 (Poorly satisfied), 3 (Not at all satisfied).
