Isdin Si-nails Strengthener 2.5 Ml

ISDIN Si-nails Strengthener is a specialized nail treatment designed to improve nail strength and appearance. This 2.5ml click-pen applicator contains cationic hyaluronic acid to increase nail thickness, density and durability while protecting and hydrating both nails and cuticles. The product should be applied directly to clean, bare nails and not over nail polish or gel. Results can be visible in as little as 14 days, though optimal results depend on initial nail condition and improve with continued use. When using for the first time, the click-pen needs to be activated by pressing the button approximately 25 times until the applicator is moistened. After initial activation, the product will flow normally with regular use.
