Clinical Trial Summary

This research seeks to evaluate the short (i.e., after single application) and long-term (i.e., after periodic application) hydrating effect of a topical preparation containing CBD and hemp oil on facial skin as well as the effect on erythema, appearance, instrumentally measured sebum production and quality of life.

Description:

In this research effort, hypothesis is that application of the topical product improves skin hydration as measured instrumentally by its electric properties as well as other variables associated with skin hydration, sebum production and appearance. Therefore, this research effort seeks to evaluate the short (i.e., after single application) and long-term (i.e., after periodic application) hydrating effect of a topical preparation containing CBD, rosemary extract and hemp oil on facial skin. For this purpose, objective measures aimed at stablishing the change of parameters related to skin water content will be measured. Additionally, other measurements will be obtained to establish the change of different parameters related to the effect on appearance, instrumentally measured sebum production and quality of life. These include: instrumental and subjective measurement of oily skin and standardized photography for assessment of imperfections as well as, a validated assessment of the impact of acne-prone skin on quality of life.

Healthy adults will be invited to participate and the general characteristics of the product will be explained, as well as the amount of time that will be required. The individuals that agree to participate will have to read and sign the informed consent, register contact information, and will be scheduled for visit 0 at the research center within 2 to 7 days. During this period (i.e., washout period), the subject will be told not to use abrasive cleansing products or topical medicines on the facial skin, not to take more than one shower per day, and not to consume caffeine or alcohol 24 hours before attending the research center.

During the washout period the subject will receive a call to confirm compliance with washout requirements as well as visit 0 schedule. If washout conditions are not met, subject will be reminded to comply and visit will be re-scheduled within 2 to 7 days.

In visit 0 at the research center, contact information, demographic variables and standard anthropometric variables will be recorded. Subsequently, the subject will be given detailed information about the research product and protocol, accompanied by an information leaflet with indications regarding the use of the investigational product as well as recommendations on preferred hygiene regimens.

The subject will be able to review the material in a room under controlled ventilation, temperature, humidity and lighting conditions, where he or she will have to stay for a minimum of 30 minutes. After that, in an adjacent room under the same conditions, the basal characteristics of the facial skin will be measured through electrical and photometric variables as well as self-assessment of oily skin, a standardized photograph with visual assessment and self-image questionnaire (i.e., hour 0). The bioengineering measurements will be made on the cheeks (i.e., between the base of the ear lobe and the apex of the chin) and forehead (i.e., exact center of the forehead) and no marking of the measurement area will be performed.

Once this process is done, the subject goes back to the waiting room, where a research assistant explains how to apply the investigational product on the face and evaluate the product characteristics. The subject applies the product and evaluates its characteristics. 10 minutes after application, the subject will complete a perception survey about the product characteristics sensation produced on the skin. Afterwards, the subject may leave the room under controlled conditions; however, he or she must return 30 minutes prior to the next measurements.

One hour after the application of the topical product (including 30 minutes of acclimatization in the room under controlled conditions), a new measurement of the electrical, photometric and colorimetric variables as well as self-assessment of oily skin and a standardized photograph with visual assessment is made. This procedure is repeated after 3 hours (including 30 minutes of acclimatization in the room under controlled conditions). Once the last measurement is made the subject completes the last part of the survey and is given a vessel containing the investigational product and instructions regarding its usage will be reinforced. Additionally, schedule for next visit will be determined at this time.

The subject must apply the product according to the indications and keep a journal of the applications. Additionally, the subject must refrain from using other topical products on the volar forearm or systemic products that may alter the skin conditions. Furthermore, there will be a follow-up call to remind the participant to comply with the requirements and confirm schedule next visit.

Two weeks after visit 0, the subject will return to the research center, where a new measurement of the electrical, photometric and colorimetric variables as well as self-assessment of oily skin, a standardized photograph with visual assessment and self-image questionnaire is made. This procedure is repeated by the 4th week, additionally, the subject will answer the last part of the perception survey in this visit. Once this is completed the product application phase will be terminated and the amount of remaining product as well as any significant journal entries will be registered at this point.

Throughout the study there will be tolerance and safety monitoring in every visit and follow-up call, as follows: Upon first application of the investigational product there will be an observation of the subject during a 15-minute period done by the research staff, a physician will be available to assess any possible allergic reaction or significant irritation.

The research staff will examine the application site of the research product to find potential local reactions and will ask about any systemic symptom. If no adverse reactions occur, the information will be recorded. Similarly, if any adverse reaction, systemic reaction or adverse event occurs it will be recorded and the physician will take the necessary measures to ensure subject safety according to his expert judgement and initiate event reporting according to applicable regulation. Finally, in every phone call made by the call center, adherence and tolerance questions will be made and recorded.

At the 5th week, the subject will receive a final follow-up call to record any events that might have appeared after removing the product, thus ending follow-up phase

In previously published studies researchers used the skinfeel spectrum descriptive analysis method to characterize skin care products. They used strict protocols for manipulation and precisely defined terms to describe the qualitative properties and their relative intensities in each product. The evaluation process was divided into four categories: pick-up (i.e., firmness, stickiness, cohesiveness, peaking); rub-out (i.e., wetness, spreadability, thickness, absorbency); residual feel; and appearance, immediate and after 20 minutes (i.e., glossy, sticky, slippery, oily, waxy, greasy	0 hours, 1 hour, and 4 weeks
