Kerasal Nail Renewal Clear & Defend Nail Repair 0.13 fl oz — Urea & Spirulina, Polish-Compatible

Kerasal Advanced Clear & Defend Nail Renewal is a twice-weekly, polish-compatible nail repair treatment that helps improve the look of damaged nails using urea and spirulina extract.

If you want a low-effort product to help restore the appearance and surface of nails without stopping regular polish, this clear treatment is formulated to create a light protective barrier while conditioning with urea and spirulina algae. Designed to work with a simple twice-a-week routine and including prep files, it aims to improve texture and shine so nails look healthier over time.

How quickly will I notice a difference in nail appearance?

Results vary by nail condition and consistency of use, but many people see improvements in surface texture and shine within a few weeks. The formula creates a protective layer to reduce friction and uses conditioning ingredients to soften and smooth the nail plate.

• Apply only twice weekly for a low-maintenance routine.
• Includes nail files to create a better surface for absorption.
• Visible smoothing and added natural sheen often reported within weeks.

Can I use this while wearing nail polish?

Yes — the product is specifically designed to be polish-compatible so you can keep wearing color. When applied over clean nails, it acts as a discreet treatment layer and also enhances the appearance of bare nails with a subtle shine.

• Works with regular nail polish without requiring removal.
• Provides a clear finish if you prefer polish-free nails.
• Twice-weekly applications fit easily into polish cycles.

What active ingredients are included and what do they do?

The key actives are urea and spirulina algae extract. Urea helps condition and hydrate the nail surface, improving flexibility and smoothness, while spirulina provides nourishing plant-derived nutrients that support overall nail appearance.

• Urea: conditions and helps reduce roughness.
• Spirulina extract: contributes plant-based nourishment.
• Barrier-forming formulation extends contact time for better performance.

How do I use the product for best results?

Prep nails with the included files, then apply the clear treatment twice each week to clean, dry nails. Regular, minimal applications maintain the barrier and conditioning benefits without interrupting polish use.

• File nails gently before application to improve adhesion.
• Apply to clean, dry nails twice weekly as directed.
• Allow to dry; continue polish use as desired.

Who is this for: Kerasal Advanced Clear & Defend Nail Renewal is aimed at people with discolored, rough, or damaged-looking nails who want a straightforward, non-disruptive treatment. It suits anyone seeking a low-frequency regimen that works with nail polish and doesn’t require daily application. If you want to improve nail surface texture and add natural shine while keeping your usual manicure routine, this compact, barrier-forming formula and included prep files offer a practical option.
