Killys Day night nail-strengthening polish Nail Hardener With Keratin 10 ml

The formula aims to strengthen soft and splitting nails through a nail-hardening polish that also supports nail health. The inclusion of a methionine derivative encourages production of keratin — a key structural protein in nails — contributing to increased resilience. The finishing effect is glossy, offering a polished look while also helping polish adhere longer and resist chipping. Regular use helps prevent splitting and breaking, particularly on nails weakened by external factors or cosmetic treatments.

Texture is similar to a standard transparent nail polish, which makes application simple whether used as a base coat, top coat, or standalone clear polish. Sensorially the polish dries with a smooth, glossy surface that helps nails look neat and well-maintained. Suitability covers nails that are soft, brittle or prone to splitting — ideal for those seeking stronger, healthier nails without colored polish.
