Isdin Si-nails Strengthener 2.5ml

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. For first-time use, activate the click pen by pressing 25 times until the applicator is moistened. Results can typically be seen within 14 days, though full benefits develop with continued use over 28 days. Users report harder, more hydrated and less brittle nails after the recommended treatment period.
