ISDIN Si-Nails Nail-Strengthening Treatment – 2.5 ml

The ISDIN Si-Nails treatment is a precision nail-care serum formulated to strengthen brittle or weak nails and hydrate cuticles. With its click-pen applicator and transparent, fast-absorbing finish, it delivers visible improvement in nail appearance in about 14 days.

Key Features

• Size: 2.5 ml click-pen format.
• Advanced formula: Contains cationic hyaluronic acid for cuticle & nail hydration, mastic oil (Pistacia lentiscus) to stimulate keratin production, and organic silicon to support nail structure and growth.
• Invisible finish & easy application: Clear serum that can be applied to clean, bare nails—no need to file or coat with polish beforehand.

How to Use

Apply daily onto clean, dry nails without nail polish. Use the brush applicator to paint along the nail edges and cuticles. Move the brush in vertical strokes from the nail root to the tip, and if possible, also apply under the nail edge. For best results, avoid washing hands or exposing nails to water for at least 6 hours after application.

Benefits

• Improves nail strength and resilience, helping to reduce breakage.
• Hydrates cuticles and nail surface, promoting smoother, healthier-looking nails.
• Supports natural nail growth and structure by boosting keratin and silicon levels.

Care Instructions

Store the product upright in a cool, dry place with the brush tip facing upward. Close the cap tightly after use. Avoid contact with open wounds or damaged nail skin. For optimal effect, prolong use until nails show visible improvement.
