ISDIN Si-Nails Nail Strengthener Pen is an advanced, fast-absorbing serum designed to improve the appearance of weak, brittle, thin, peeling, and damaged nails. Its innovative click-pen applicator ensures precise delivery of key ingredients to the nail, cuticle, and nail edge.

Formulated with Silanediol Salicylate (Organic Silicon) to support nail strength and growth, Pistacia Lentiscus (Mastic) Gum to promote keratin production, and Cationic Hyaluronic Acid for hydration, this serum helps to reduce nail breakage and splitting. Biosaccharide Gum-2 protects nails from external aggressors.

This fragrance-free, invisible-finish formula is suitable for daily use without leaving residue. Apply once daily to clean, dry, unpolished nails for at least 14 days for optimal results, ideally in the evening to allow for absorption.
