Very dry, hard, or brittle nails often occur due to external factors (harsh chemicals, frequent contact with water, or overexposure to the sun...), but also due to internal factors (age, diet, heredity...). Mava-Flex is a well-balanced concentrate with urea, saccharides, hyaluronic acid, calcium, lemon essential oil and vitamin B5. Its goal is to maintain a good balance in hydration, to restore and maintain the flexibility of the nail plate. It also helps to reinforce the structure of brittle nails. Ideal for toenails, which are usually very hard.
