Study Summary

The goal of this clinical trial is to learn if a novel barrier topical product works to treat barrier dysfunction in adults. It will also learn about the safety of the novel barrier topical product. The main questions it aims to answer are:

Does the novel barrier topical product improve skin hydration, skin sebum, redness, and pigmentation? Does it improve subjective dryness and itch? Researchers will compare the novel barrier topical product to petrolatum (a gold standard occlusive barrier repair agent) to see how they are comparable in treating skin barrier dysfunction.

Participants will:

Apply the novel barrier topical product or petrolatum twice a day for 28 days Visit the clinic once a week for checkups and tests Keep a diary of their application of the assigned product

Study Description

The goal of this randomized controlled trial is to determine the efficacy of a new barrier product (containing ceramide, virgin coconut oil, cholesterol) versus petrolatum in adults with skin barrier dysfunction (including mild to moderate psoriasis, atopic dermatitis, contact dermatitis, seasonal xerosis or clinically evident skin dryness).

The main questions it aims to answer are:

Primary Objective: In a pilot study, to compare the preliminary effectiveness of the test product (containing ceramides, cholesterol, coconut oil and monolaurin) versus petrolatum in improving skin barrier function, as measured by transepidermal water loss (using a Tewameter), skin hydration (using a Corneometer), skin lipids (using a Sebumeter) as well as skin erythema and pigmentation (using a Mexameter) over a four-week period.

Secondary Objectives:

To assess improvement in subjective symptoms (dryness, pruritus). To assess patient-reported outcomes, including comfort, ease of application, and overall satisfaction.

To monitor and compare any adverse events or skin reactions associated with both treatments.

Researchers will compare versus petrolatum to see if effects are comparable. Participants will upon enrollment to the study, be asked to accomplish the Personal Information Sheet and Patient Satisfaction Questionnaire. They will be taught how to mark the Visual Analogue Scale according to the degree of dryness and itch felt. They will accomplish this at Baseline, weeks 1, 2 and 4.

Non-invasive measurements will be done of: skin hydration (using Tewameter and Corneometer), skin sebum (using Sebumeter) and skin redness/pigmentation (using Mexameter) at baseline, weeks 1, 2, and 4. Pictures will also be taken of the test area at each visit.

All participants will be given a 1 or 3-week supply of either the test medication or the placebo in identical jars, color, and smell to maintain blinding. Refills will be given at each follow-up. Written instructions on how to use them will also be provided. The product will be applied twice daily on the right forearm for 28 days. The amount applied will be ⅛ teaspoon per application, with a plastic measuring spoon given for their use. They will be instructed not to apply the product to any other location. They will also be advised on the possible adverse effects and will be instructed to contact the investigator in case an adverse reaction happens. They will then be instructed to follow up after 1, 2, and 4 weeks.
