A Multi-Center, Open-label Study Evaluate the Efficacy and Tolerability of a Dual Skincare Regimen Treatment for Facial Hyperpigmentation and Photodamaged Skin in Patients Exposed to Extrinsic Factors of Aging

A Multi-Center Clinical Trial to Evaluate the Efficacy and Tolerability for Treatment of Facial Hyperpigmentation and Photodamaged Skin With a Dual Regimen Treatment Containing Vitamin C and a Tinted SPF 45 Moisturizer

This open-label, multi-center clinical trial was conducted to evaluate the dual skincare regimen of vitamin C serum and moisturizing sunscreen SPF 45 to improve facial hyperpigmentation and photodamage after 12 weeks of twice daily use in healthy female subjects between 35 - 60 years old. A total of 33 subjects completed study participation.

Study Overview

• Status: Completed
• Conditions: Hyperpigmentation; Wrinkle; Photodamaged Skin; Fine Lines
• Intervention / Treatment: Other: Gentle Cleansing Lotion, Revision Skincare

Detailed Description

This open-label, multi-center clinical trial was conducted to evaluate the dual skincare regimen of vitamin C serum and moisturizing sunscreen SPF 45 to improve facial hyperpigmentation and photodamage when used twice daily over the course of 12 weeks by healthy women with Fitzpatrick skin type I - V, moderate to severe global face hyperpigmentation and moderate global face photodamage.

Efficacy and tolerability will be assessed through clinical grading at baseline, weeks 4, 8 and 12. Efficacy evaluation for hyperpigmentation (mottled), hyperpigmentation (discrete), overall photodamage, clarity/brightness, overall appearance, skin tone evenness (redness), fine lines and wrinkles. Investigator and subject tolerability, self-assessment questionnaire and clinical VISIA photography will be completed at baseline, weeks 4, 8 and 12. Subject testimonials will be completed at week 12.

A total of 33 subjects completed study participation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Improvement in clinical efficacy of hyperpigmentation versus Baseline	The primary efficacy endpoint will be the Investigator Clinical Grading using Modified Griffith's 10-point Scale. A change in scores at week 4, week 8 and week 12 in comparison to baseline indicates an improvement for the indicated parameter. Global facial hyperpigmentation will be assessed on each subject's face using a modified Griffiths' 10-point scale according to the following numerical definitions (half-point scores may be used as necessary to more accurately describe the skin condition): 0 = none (best possible condition); 1 to 3 = mild; 4 to 6 = moderate;7 to 9 = severe (worst possible condition). The lower the score equates to the best possible outcome.	12 weeks
Lack of Significant Increase in Objective Investigator Tolerability Parameters at week 4, 8, 12 compared to Baseline	The primary tolerability endpoint will be favorable analysis of the Investigator Tolerability Assessment of Erythema, Edema and Dryness. A change in scores or lack of significant change at week 4, week 8 and week 12 in comparison to Baseline indicates tolerability/safety of the test material. Four point scale with a lower score indicating a better outcome. Example for Erythema: 0 = None No erythema of the treatment area, 1 = Mild Slight, but definite redness of the treatment area, 2 = Moderate Definite redness of the treatment area, 3 = Severe Marked redness of the treatment area	12 weeks
Incidence and severity of adverse events	The primary safety endpoint will be determined by the incidence and severity of adverse events in healthy subjects through-out the length of the study.	12 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Improvement in clinical efficacy of photodamage versus Baseline	The secondary efficacy endpoint will be the Investigator Clinical Grading using Modified Griffith's 10-point Scale. A change in scores at week 4, week 8 and week 12 in comparison to baseline indicates an improvement for the indicated parameter. Global facial photodamage will be assessed on each subject's face using a modified Griffiths' 10-point scale according to the following numerical definitions (half-point scores may be used as necessary to more accurately describe the skin condition): 0 = none (best possible condition); 1 to 3 = mild; 4 to 6 = moderate;7 to 9 = severe (worst possible condition).

Lack of Significant Increase in Objective Subject Tolerability Parameters at week 4, 8, 12	The primary tolerability endpoint will be favorable analysis of the Subject Tolerability Assessment of Erythema, Edema and Dryness. A change in scores or lack of significant change at week 4, week 8 and week 12 in comparison to Baseline indicates tolerability/safety of the test material. Four point scale with a lower score indicating a better outcome. Example for Erythema: Erythema 0=None No erythema of the treatment area,1=Mild Slight, but definite redness of the treatment area, 2=Moderate Definite redness of the treatment area, 3=Severe Marked redness of the treatment area	12 weeks
