Study Overview
=================
Brief Summary
-----------------
The objective of the study is to investigate the effects of different skincare regimens on infants (0-6 months old at the start of the study), specifically focusing on moisturization effect. Outcome measures include moisturization, skin pH, skin barrier, physiological parameters, reactivity and skin microbiome.

Detailed Description
-----------------
This is a single-center, single-blind, parallel study in healthy, full-term, male or female infants aged 0-6 months at the start of the study.

Test wash should be used no more than once in the same day. The participating parent/legal guardian must be willing to apply the provided test lotion at least once per day, in the morning.

Parent/legal guardian must agree not to expose his/her newborn participating in the study to excessive sun exposure. Parent/legal guardian must agree for the newborn to avoid extended sun exposure during the peak periods of 11 AM to 4 PM. If newborn is briefly exposed to the sun, parent/legal guardian will make every attempt to use protective clothing. No use of sunscreen is allowed throughout study participation. Parent/legal guardian must agree not to permit their newborn from participating in another study for the duration of the study. Parent/legal guardian must agree for the newborn to avoid the beach during the course of the study, and any activities at or in a swimming pool should be documented in the daily diary. Evidence of a personally signed and dated Informed Consent document indicating that the Parent/legal guardian has been informed of all pertinent aspects of the trial. Parent/legal guardian who is willing and able to comply with scheduled visits, study procedures, and other trial procedures. Exclusion Criteria: Any disease or condition of the skin (i.e. dermatitis, eczema, psoriasis, rosacea) that the Investigator deems inappropriate for participation. Any newborn with clinically determined moderate to severe dryness (>2.0) or clinically determined erythema (>0.5), rash (>0.5), or an overall skin condition which, in the Investigator's judgment, makes the subject ineligible or places the subject at risk will not be enrolled in the study. Any condition requiring use of a topical or oral OTC or prescription medication, which, in the investigator's judgment, makes the subject ineligible or places the subject at risk (e.g. antibiotics or any other medications that may cause gastrointestinal distress/diarrhea that will affect skin condition/cause irritation/rash of genital/buttocks area). Child vitamins are allowed and should be listed on the Medical Information sheet under the Concurrent Medications section. Individuals currently involved in another clinical study of any type, or planning to participate in another clinical study of any type during this study. Newborn participant who exhibits or is known to have atopic dermatitis, eczema, or other inflammatory disease, or mild to severe diaper rash or skin diseases/conditions that in the opinion of the investigator may affect the evaluation of study product or place the newborn at undue risk. Newborn participant or parent/legal guardian who has experienced unusual hypersensitivity or allergic reactivity to fragrances and/or reaction/irritation to skin care toiletry products, or who has known allergies/sensitivities to ingredients in the provided test products. Newborn participant or parent/legal guardian with a known condition of asthma or any related breathing problems and/or for whom there is a family history of asthma. Newborn participant with chronic medical conditions or treatments that could interfere with the study or pose a risk to the newborn (including known immunodeficiency or lung related conditions). Newborn participant with active localized or general infections including upper respiratory infections (ear, nose, throat, fever, cough, etc.). Conditions that may interfere with the evaluation of the trial results, e.g., medical characteristics, diseases, or therapy that may interfere with the effect of the investigational product or with the evaluation of efficacy or safety variables. The conditions may also include concurrent use of another investigational product or prior use of an investigational product or approved medication or other drug within a defined period prior to trial enrollment. Conditions for which subjects should be excluded for safety reasons, e.g., medical characteristics, disease, or therapy that may constitute contraindications or risks in connection with the use of the investigational product or the specified methods of evaluation. Participation in other clinical trials within 30 days before the current trial begins and/or during trial participation Other medical conditions that may increase the risk associated with trial participation or may interfere with the interpretation of trial results and, in the judgment of the investigator, would make the subject inappropriate for entry into this trial. Parent/Legal guardian of the newborn is an employee of the investigator or study center or is a family member of the employees or the investigator.
