The liquid product is transformed into a fine foam with a high concentration of urea and lactic acid by means of a dosing system without the use of propellant. It allows you to soften the hard horn skin, quickly, accurately and exactly where needed. In only approximately 5 minutes, the softened stratum corneum removes easily, which reduces the processing time considerably. The foam sticks to the skin and does not run away. Antimicrobial. No added fragrances.
