Mava-Flex is a balanced concentrate that repairs and maintains the flexibility of very dry or hard nails, or nails that have been altered by contact with aggressive chemical products, external factors (constant contact with water, long exposure to the sun...) but also internal factors (age, diet, heredity...). How to use: Apply with the brush over the entire surface of the nail after having removed any remaining nail polish or cream. Massage with your thumb and let it penetrate. If you continue with the manicure be sure to remove excess product with soft paper. Use twice a week on nails after removing make-up, ideally before going to bed to allow it to work overnight.
