The 40% medical-grade urea penetrates the nail surface to soften hardened areas so filing and trimming become easier, while hydration and conditioning encourage smoother, clearer nails over time. Regular application helps newly forming nails grow in with improved texture and tone.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will I see changes after I start using the gel?\u003c\/h3\u003e\n\u003cp\u003eResults follow a steady timeline: softening begins within the first 1–2 weeks, visible improvement in color and thickness appears around weeks 3–4, and continued strengthening is typically evident by 4–6 weeks.
