Eligibility | Inclusion Criteria: - Post-menopausal women of Fitzpatrick skin types 1 and 2 Exclusion Criteria: - Those with a nut allergy - Smoking is an independent risk factor and serves as a confounder for the development of facial wrinkles and photoaging [14]. Therefore, current smokers, those that have smoked within the past year, and former smokers with greater than a 20-pack year history of smoking will be excluded. - Those with an autoimmune photosensitive condition or a known genetic condition with a deficiency in collagen production (such as Ehlers-Danlos syndromes) will be excluded as this can be a confounder for facial wrinkles. - Those who have undergone any cosmetic procedures to the face in the 4 months prior to enrollment in the opinion of the investigator. People that have undergone deeper chemical peels (TCA based peels) within 1 year prior to enrollment will also not be eligible. - Individuals who are unwilling to discontinue vitamin E food sources during the washout and intervention. This includes - Vitamin E containing supplements. - Sunflower seeds or sunflower oil. - All nuts. - Individual who are unwilling to discontinue topical cosmetic products during the duration of the study or unwilling to undergo a 2-week washout of topicals that are known to modulate collagen and pigment: - Retinoids such as tretinoin, adapalene, retinol, except as provided by the study. - Antioxidant ingredients such as vitamin C or vitamin E. - Pigment reducing agents such as hydroquinone, a retinoid, azelaic acid, kojic acid, pomegranate seed oil, and other similar agents per the discretion of the investigator, except for the retinol that is provided in this study. - Topicals that contain a nut oil or nut extract as part of their ingredient list. |

Primary | Appearance of wrinkle severity | Facial wrinkles will be assessed with the use of a validated high resolution facial modeling system. The high-resolution facial modeling system will be performed with the 3D Clarity Pro® Facial Modeling and Analysis System (Brigh-Tex BioPhotonics, San Jose, CA) and will specifically assess for wrinkle severity and wrinkle length as was performed in the previous pilot study. | 12-weeks | |
Secondary | Appearance of facial color tone and evenness | The facial color tone and evenness will be measured with a SkinColor Catch from Delfin Technologies. This device shows the RGB Colors, CIE L*a*b* and L*c*h* color space coordinates when the devivce is applied to the skin. Included is the link to the device (http://www.truesystem.co.kr/product/pdf/SkinColorCatch%20Brochure%202016.pdf). | 12-weeks | |
Secondary | Appearance of facial redness | We will quantify the presence of facial redness with a SkinColor Catch from Delfin Technologies. We will measure the RGB colors and average them from each participant for each of the visits. Skin pigment, including the presence of redness, will be measured using a SkinColorCatch from Delfin Technologies . This device shows the RGB Colors, CIE L*a*b* and L*c*h* color space coordinates when the devivce is applied to the skin. Included is the link to the device (http://www.truesystem.co.kr/product/pdf/SkinColorCatch%20Brochure%202016.pdf). | 12-weeks | |
Secondary | Subjective tolerability | To assess tolerability, we are going to use a Tolerability Assessment Questionnaire. The patient fills out the questionnaire on whether they currently have or had any itching, burning, stining, scaling, erythema, hypopigmentation or hyperpigmentation during application of the product. They measure any of the symptoms on a scale of 0-3, 0 being none, 3 being severe. They can also hand write any other effects that they noticed from the study. | 12-weeks |
