ProRenew Complex CLR by CLR Berlin acts as a regenerating agent, restructuring, anti-aging agent and anti-stress agent. It is obtained from a lysate of the gram positive bacterial species lactococcus lactis, which is fermented under special conditions of catabolic repression. The biotechnologically obtained suspension contains fragments such as DNA, metabolites, cytoplasmic compounds and cell wall materials in a moderate acidic, aqueous medium. ProRenew Complex CLR is non-irritant, stimulates skin's renewal processes and accelerates the recovery of skins barrier function, regardless of type of impairment (environmental stress, aging). It is miscible with water and water-alcohol mixtures containing a maximum alcohol concentration of 50% w/w, but yields no clear solutions. Used in skin care emulsions but also in gel-type type formulations or serums, which are stabilized with suitable hydrocolloids or polymers.
