Brief Summary:
Subjects will be assigned to a retinoid cream or bakuchiol to compare the cosmetic effects. This will take place over a 12 week period.

Condition or disease Intervention/treatment Phase
Wrinkle Photoaging Drug: Bakuchiol Drug: Retinol Early Phase 1

Detailed Description:

Bakuchiol is a phytochemical that has demonstrated cutaneous antiageing effects when applied topically. Early studies have suggested that bakuchiol is a functional analogue of topical retinoids, as both compounds have been shown to induce similar gene expression in the skin and lead to improvement of cutaneous photodamage. No in vivo studies have compared the two compounds for efficacy and side-effects.

The aim of this study is to compare the cosmetic effects of Bakuchiol to Retinol over a 12-week period.

Primary Outcome Measures :
  1. Change in Wrinkle Appearance [ Time Frame: 12 week ]

    Assessed using image analysis based assessment of wrinkle severity (depth and length).

    The primary outcome measure was image-analysis-based assessment of wrinkle severity and pigmentation at 12 weeks.


  2. Percentage of Participants With Change in Appearance of Skin Pigmentation [ Time Frame: 12 week ]
    Assessed using image analysis based assessment of facial pigment


Secondary Outcome Measures :
  1. Number of Reports of Stinging, Burning, Itching [ Time Frame: Assessed at Week 4, 8, and 12. ]
    Subjective tolerability assessment of stinging, burning, itching. Secondary outcome measures included redness, participant-reported tolerability (itching, burning and stinging) and in-person clinical assessments (pigmentation, scaling and erythema) throughout the study.

  2. Number of Reports of Facial Erythema Assessment [ Time Frame: week 4, week 8 and week 12 ]
    Image analysis based assessment of facial erythema
