Brief Summary
Acne vulgaris (acne) is a chronic inflammatory pathology of the pilosebaceous unit. Its prevalence is about 85% of teenagers and is constantly increasing in adults, especially women. Acne is a multifactorial disease involving abnormalities in follicular keratinization, sebum production, skin microbiota and inflammation. The early stage of acne is characterized by the presence of primary retentional lesions: the open comedones (or blackheads) and closed comedones (or whitehead). These retentional lesions can progress to highly inflammatory lesions: superficial inflammatory lesions (papules and pustules) and in some cases in deep inflammatory lesions (nodules). Finally, acne lesions can lead to the development of superficial post inflammatory erythema or hyperpigmentation, resulting in emotional distress and a poorer quality of life. Currently, a better understanding of the switch from healthy to acne-prone skin, but also of the transition from retentional lesions to more severe inflammatory lesions, seems essential to propose adapted and specific treatments. The aim of this study is to better understand acne pathophysiology of the face by a multi-omic approaches, biometrological analysis and consumer needs collection to bring information, in the same study on the local ecosystem of non-lesional areas, retentional lesional areas and inflammatory lesional areas of adult acne prone skin, compared to acne free face.

Study Arms (2)
Control subject group
OTHERSubject group with mild to moderate acne on the face
OTHERInterventions
Measurements will be taken from the face: * For acne group: inflammatory lesional area and non-lesional area * For control group: non-lesional area
Samples will be taken from the face: * For acne group: inflammatory lesional area, non-lesional area and retentional area * For control group: non-lesional area
Only for acne group: acne scores will be evaluated on the face by the investigator
Only for acne group: consumers' perception
