• A body surface area (BSA), as measured by Mosteller BSA Calculator, between 1.26 m^2 (e.g., 4 feet, 10 inches and 85 pounds [38.6 Kg] and 2.25 m^2 (e.g., 6 feet, 3 inches and 210 pounds [95.5 Kg]; and

• Females of childbearing potential who are willing to use adequate contraception 30 days prior to the Screening Visit and until participation in the study is complete.

  --Females of childbearing potential must agree to use an acceptable method of birth control (e.g. total abstinence, oral contraceptives, intrauterine device [IUD], barrier method with spermicide, surgical sterilization or surgically sterilized partner, Depo-Provera, Norplant, NuvaRing, or hormonal implants) for the duration of study participation.

• Male participants who are willing to use an acceptable method of contraception (e.g. barrier methods with spermicide, surgical sterilization or surgically sterilized partner) or practice abstinence until participation in the study is complete.

Exclusion Criteria:

• Inability or unwillingness of participant to give written informed consent or comply with study protocol;
• Pregnant or lactating females, or females who desire to become pregnant and/or breast feed within the duration of study participation;
• Active bacterial, viral, or fungal skin infections;
• Any noticeable breaks or cracks in the skin on the upper extremities, including severely excoriated skin or skin with open or weeping wounds suggestive of an active infection or increased susceptibility to infection;
• Sensitivity to or difficulty tolerating Dove fragrance-free bar soap, Cetaphil(R) Lotion, alcohol-based cleaners, macadamia nuts, soy, Vegetable glycerin, or palm kernels;
• Participants with prosthetic heart valves, pacemakers, intravascular catheters, or other foreign or prosthetic devices;
• Participants with Netherton's syndrome or other genodermatoses that result in a defective epidermal barrier;
• Any participant who is immunocompromised (e.g. history of lymphoma, Human Immunodeficiency Virus (HIV)/ Acquired Immune Deficiency Syndrome (AIDS), Wiskott-Aldrich Syndrome) or has a history of malignant disease (with the exception of non-melanoma skin cancer);
• Participants with a history of psychiatric disease or history of alcohol or drug abuse that would interfere with the ability to comply with the study protocol;
• Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study;
• Ongoing participation in another investigational trial or use of investigational drugs within 8 weeks, or 5 half-lives (if known), whichever is longer, of the Screening Visit;
• Treatment with biologics within 16 weeks of Screening Visit;
• Participants with close contacts (e.g. spouses, children, or members in the same household) that have severe barrier defects or are immunocompromised;
• Use of topical (including steroids and calcineurin inhibitors) Atopic Dermatitis (AD) treatments within 7 days of the Treatment Visit; Use of topical steroids on areas outside of where investigational product is to be applied may be permitted, per investigator discretion;
• Treatment of AD with prescription moisturizers classified as medical device (e.g., Atopiclair®, MimyX®, Epicerum®, Cerave®, etc.) within 7 days of the Treatment Visit;
• Use of any oral or topical antibiotics within 7 days of the Treatment Visit;
• Participants who have taken a bleach bath within 7 days of the Treatment Visit;
• Use of any oral AD therapies (antihistamines, steroids, immunosuppressive therapies) within 28 days of the Treatment Visit; or
• Any phototherapy for skin disease (such as narrow band ultraviolet B [NBUVB], ultraviolet B [UVB], ultraviolet A1 [UVA1], psoralen + UVA [PUVA]) or regular use (more than 2 visits per week) of a tanning bed within 28 days of the Treatment Visit.
