Isdin Si-nails Strengthener 2.5ml

ISDIN Si-nails Strengthener is a specialized nail treatment pen designed to improve nail strength and appearance. Featuring Cationic Hyaluronic Acid, this 2.5ml product helps restore natural nail health by increasing thickness, density and durability of both nails and cuticles. The product comes in a convenient click-pen applicator that requires activation before first use by clicking 25 times until the applicator is moistened. For best results, apply directly to clean, bare nails - not over nail polish or gel. Results can be visible in as little as 14 days, though improvement continues with extended use. The treatment should be applied to dry, polish-free nails for optimal absorption and effectiveness.
