The present invention relates to selected strains of lactic bacteria for use in the treatment of infections caused by pathogenic bacteria belonging to the species Propionibacterium acnes, in particular for use in the preventive and/or curative treatment of dermatitis in general, seborrheic dermatitis, rosacea, eczema and acne. In addition, the present invention relates to a composition which comprises a mixture comprising or, alternatively, consisting of selected strains of lactic bacteria for use in the treatment of infections caused by pathogenic bacteria belonging to the species Propionibacterium acnes, in particular for use in the preventive and/or curative treatment of dermatitis in general, seborrheic dermatitis, rosacea, eczema and acne. The composition comprising said mixture of selected strains of lactic bacteria is formulated in a pharmaceutical form for oral use (novel food, supplement product or medical device or pharmaceutical composition) in the form of powder, dispersible powder, granulate, packets or stick, solution, spray solution, syrup, tablet, capsule, pill or lozenge; or for topical use (composition for medical device or pharmaceutical composition) in the form of cream, ointment, pomade, gel, hydrogel, dispersion, emulsion or spray to be used as such for skin applications, or for transdermal use even in the form of a band aid.

The present invention generally relates to the field of skin care. More particularly, the invention relates to a cosmetic or therapeutic skin care composition comprising live bacteria of at least one Cutibacterium acnes (C. acnes) strain in combination with an excipient that specifically supports their viability during storage and/or their ability to replicate after application to the skin. Preferably, the cosmetic or therapeutic skin care composition comprises bacteria of at least one C. acnes strain selected from the group consisting of D1, A5, C1, C3, H1, H2, H3, K1, K2, K4, K6, K8, K9, L1, and F4. The invention also provides a method for treating or preventing acne by applying the skin care composition of the invention to a skin area in need of treatment. The invention also relates to the use of a skin care composition of the invention for treating or preventing acne.
