Mavala Mava-Flex SerumIndication: It is blood that nourishes the nail roots. If you suffer from bad circulation, nails can grow very slowly. Mavaderma is a balanced blending of wheat germ, olive and sweet almond oils to massage onto the nail root area for more beautiful and longer nails. The emollient action of the oils keeps skin supple and soft. How to use: To be used twice a week on bare nails, ideally before going to bed to allow this serum to act during the night.
