Lysaskin Xerolys 50 Emulsion 40 ml is a highly concentrated keratolytic and moisturizing treatment designed for extremely thickened and hardened skin areas such as heels, elbows, and knees. Containing 50% urea, this emulsion works to soften stubborn calluses and rough patches by breaking down excess keratin while deeply hydrating the skin. The addition of lactic acid promotes gentle exfoliation, and glycerin provides lasting moisture retention. Its rich yet easily absorbable texture helps restore skin softness, flexibility, and comfort with regular use.
