Provided is a multi-component regimen for the treatment of a skin condition, comprising administering at least two components selected from the group consisting of administering at least one galenic microbial composition, applying at least one acidic composition, applying at least one mineral salt composition, illuminating an area of the skin and heating an area of the skin, wherein the regimen comprises at least one of administering at least one galenic microbial composition and illuminating an area of the skin. Also provided is a galenic microbial composition comprising bacteria of the phylum Actinobacterium and a dermatologically compatible carrier. Further provided is a wearable cutaneous -treatment device for the therapeutic illumination of mammalian skin, comprising a support component having an inner surface, said support component dimensioned to cover an area of skin of a subject; at least one light source arranged on said inner surface, the light source or light sources constituting an illumination panel; and at least one attachment component for reversibly securing the device to a mammalian subject so that said inner surface faces an area of skin of the subject, said light source or sources configured, when activated, to project light outwards from said inner surface to illuminate at least a portion said area of skin.L'invention concerne un régime à composants multiples pour le traitement d'une affection cutanée, comprenant l'administration d'au moins deux composants choisis dans le groupe constitué par l'administration d'au moins une composition microbienne galénique, l'application d'au moins une composition acide, l'application d'au moins une composition de sel minéral, l'exposition d'une zone de la peau à éclairage et chauffage, où le régime comprend au moins l'une parmi l'administration d'au moins une composition microbienne galénique et l'exposition d'une zone de la peau à éclairage. L'invention concerne également une composition microbienne galénique
