Brief Summary:

The study consists in the application of 2 investigational products (one group per investigational product) under normal conditions of use, in adult participants with Atopic Dermatitis.

It is carried out on cosmetic products, with the aim to further confirm safety of these products

Condition or disease Intervention/treatment Phase
Atopic Dermatitis Other: Topical Ointment with L. reuteri Other: Topical Ointment without L. reuteri Not Applicable

Detailed Description:

Probiotics are live micro-organisms which when administered in adequate amounts can exert a health benefit on the host. This health-promoting effects of Lactobacillus reuteri have been extensively studied in the gastrointestinal tract but it is clear that other areas are also interesting for the use of probiotics.

Atopic Dermatitis is a relapsing inflammatory skin disease appearing on persons with a genetic predisposition of allergic pathology. AD generally starts in childhood, however in some cases can continue into adult hood, in at least 10% of cases. AD can effect a persons quality of life and in the chronic stage it can present with dry skin and lichenification.

Research has shown that probiotics have an antimicrobial, anti-inflammatory and barrier function effect, and could therefore be used on subjects with Atopic Dermatitis to relieve and protect.

Primary Outcome Measures :
  1. Appraisal of Cutaneous acceptability of the investigational products by dermatologist investigator [ Time Frame: 4 weeks ]
    Cutaneous acceptability is assessed on the basis of clinical examination of the skin for physical signs (erythema, oedema, dryness) linked to the use of the investigational product and also evaluation the functional signs (prickling, tightness, heating)

Secondary Outcome Measures :
  1. Change in SCORAD index over 8 week period [ Time Frame: baseline, at 4 and 8 weeks ]
    Clinical evaluation by the dermatologist investigator to assess change in skin conditions to each parameter of "SCORing Atopic Dermatitis" (SCORAD) (erythema, edema, xerosis) and participant symptoms: pruritus and sleep quality

  2. Change in Local SCORAD index [ Time Frame: baseline, at 4, and 8 weeks ]
    Change evaluated by the dermatologist investigator at each visit, on the recurrent lesion (defined area) and control area selected at baseline

Other Outcome Measures:
  1. Appraisal of cosmetic acceptability of the investigational products by participant questionnaire [ Time Frame: 4 weeks ]

    Cosmetic acceptability of the products through participant filling in questionnaire adapted to the products, elaborated in collaboration with the study monitor.

    The questionnaire will address functional and physical signs of a reaction (application frequency, nature, location, intensity, duration)

    Conclusion on cutaneous acceptability: Very good/ Good / Moderately Good / Bad
