Often, dry, too hard and brittle nails are damaged due to external agents (harsh chemicals, constant contact with water, excessive exposure to the sun, ...) but also by internal factors (age, diet, heredity, ...). MAVA-FLEX is a balanced concentrate based on urea, saccharides and hyaluronic acid, calcium, lemon essential oil and vitamin B5. It aims to maintain a good moisture balance in order to restore and maintain its flexibility to the nail plate. It also helps to strengthen the structure of nails that are brittle due to drying products or altered by external factors. Also ideal for toenails, which are generally quite hard.
