The Effect of Almonds on Facial Aesthetics and Modulation of the Microbiome and Lipidome
A study testing Almond in people with Wrinkle, run by University of California, Davis at 1 site in United States.
Trial summary
The investigator hypothesizes that regular consumption of almonds will 1) improve the facial wrinkle severity in post-menopausal women, 2) improve the evenness of facial skin pigmentation, 3) diversify the gut microbiome and increase the short chain fatty acids in the blood, and 4) improve the skin barrier biophysical… Read more about this study

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 100 years
- Women only
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Postmenopausal women
- Fitzpatrick skin types 1 and 2
- Able to follow dietary intervention and attend all study visits
Who cannot join
- Those with a nut allergy
- Current smokers, those that have smoked within the past year, and former smokers with greater than a 20 pack-year history of smoking, as smoking is a independent risk factor and serves as a confounder for the development of facial wrinkles
- Those with an autoimmune photosensitive condition or a known genetic condition with a deficiency in collagen production (such as Ehler-Danlos), as this can be a confounder for the development of facial wrinkles
- Those that already obtain 20% of their energy intake from nut consumption
- Those with implausible reported energy intakes of <1,000 kcal/d or >3,000 kcal/d

About this study
The investigator hypothesizes that regular consumption of almonds will 1) improve the facial wrinkle severity in post-menopausal women, 2) improve the evenness of facial skin pigmentation, 3) diversify the gut microbiome and increase the short chain fatty acids in the blood, and 4) improve the skin barrier biophysical properties.
Read the detailed description
This study will be a 24 week supplementation study that utilizes two study groups: 1) control group and 2) almond supplementation: 20% energy intake. This will be a randomized, rater-blinded, and controlled study. There will be a total of 60 subjects, with 30 assigned to the control group and 30 assigned to almond supplementation.
Subjects will be recruited from the UC Davis Dermatology Clinic, UC Davis Main campus, California State University- Sacramento, and from the surrounding community physicians and the community in a 100 mile radius. The greater Sacramento area has a population of over 2 million to draw from and recruitment will be conducted through the use of Social Media and flyer based recruitment. Postmenopausal women have previous been recruited successfully in a previous study. The study visits will be performed at the UC Davis Dermatology Clinic located at 3301 C Street, Suite 1400, Sacramento, CA 95816.
Investigators will collect medical history and current medications from study participants- this is outlined in the HIPAA form. The two intervention groups will consist of those receiving almonds and those that are receiving a calorie matched snack. The almond dose will be provided as 20% of total energy (20% E) in the diet. This dose was selected based on a previous randomized trial examining lipid parameters in response to 0, 10%, and 20% E as dietary almonds and a recent meta-analysis of intervention trials of tree nuts [5, 6]. The control snack will be a typical western diet snack (see Table 1) . The calorie matched snacks are commercially available prepackaged snack items that will be purchased from Costco. Once a subject has met inclusion criteria and has signed IRB consent, anthropometric data will be obtained, 1-24 hour recall will be collected, training will be provided for recording dietary records, and estimated caloric needs will be calculated. Estimated energy needs (EER) will be determined using the Mifflin-St. Jeor equation and total daily energy needs (TDE) calculated as EER x activity factor of 1.3-1.5 for sedentary to average activity, or a higher activity level as indicated. A representative example of a 60 year old woman, 5'4", 140 pounds with typical activity level yields TDE of approximately 1,600 - 1,800 kcal/day, and 20% E of 320-360 kcal/day. The intervention and control snacks would be 56.7 g of almonds and 56.7 g pretzel + one-24 g chewy granola bar, respectively.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in wrinkle severity
Photographs will be obtained at baseline, 8 weeks, 16 weeks, and 24 weeks. The images will be obtained with the 3D Clarity Pro® Facial Modeling and Analysis System (Brigh-Tex BioPhotonics, San Jose, CA) that has standardized positioning and lighting and iPad. The investigator has already validated this measurement tool against standard clinical grading of facial wrinkles.
Measured: 24 weeks
Secondary outcomes (5)
Change in facial pigmentation
Photographs will be obtained at baseline, 8 weeks, 16 weeks, and 24 weeks. The images will be obtained with the 3D Clarity Pro® Facial Modeling and Analysis System (Brigh-Tex BioPhotonics, San Jose, CA) that has standardized positioning and lighting and iPad. This system can assess facial pigmentation evenness and average intensity. The investigator has already validated this measurement tool against standard clinical grading of facial pigmentation.
Measured: 24 weeks
Change in appearance of facial wrinkles on lateral canthi
Two blinded physician graders will grade the photographs obtained at each of the time points on the lateral canthi ("crow's feet").
Measured: 24 weeks
Change in facial sebum production
Change in facial sebum production through the use of a Sebumeter, a commonly used device that measures sebum excretion rate. Sebum excretion rate will be measured at baseline, 8 weeks, 16 weeks, and 24 weeks.
Measured: 24 weeks
Change in the serum profile
Change in the serum and sebum lipid profile for assessment of long chain/short chain fatty acid ratios and the NS ceramide content.
Measured: 24 weeks
Change in sebum lipid profile
Change in the sebum lipid profile assessment of long chain/short chain fatty acid ratios and the NS ceramide content.
Measured: 24 weeks

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in wrinkle severity (time frame: 24 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2021.
