Ingredients
The formula includes cationic hyaluronic acid, known for its strong adhesive properties and ability to retain hydration in nails, skin, and hair. Mastic oil derived from Pistacia lentiscus enhances the synthesis of hard keratin and related proteins, which results in thicker, more resilient nails. Organic silicon easily penetrates the nail bed, encouraging healthier nail growth and reinforcing nail structure.
