Achieve salon-quality results at home with the RefectoCil Lash and Brow Tint. This professional-grade tint is smudge-proof and waterproof, providing even color and enhanced definition that lasts for 4-6 weeks. Each 15ml tube offers approximately 30 applications. For optimal results, apply regularly; the color penetrates deeply into lashes or brows with each use, resulting in more intense and lasting color.
