Isdin Si-Nails Nail Strenghthener

ISDIN Si-Nails is a professional nail strengthening treatment that uses cationic hyaluronic acid to improve nail thickness, density and durability. This 2.5ml click-pen applicator helps restore natural nail appearance, making them harder, more hydrated and less brittle with visible results in 14-28 days of regular use. The product should be applied directly to clean, bare nails and not over nail polish or gel. For first-time use, activate the click pen by pressing the button 25 times until the applicator is moistened. Results vary based on initial nail condition but improvement continues with extended use. The unique formula contains cationic hyaluronic acid to strengthen brittle nails and protect nail health.
