Introduction
Toenail fungus is a common yet frustrating condition that affects millions of people. It can cause discoloration, thickening, and brittleness, leading to embarrassment and discomfort. Treating fungal nails can be challenging, and many turn to over-the-counter solutions for help.
Users seeking to improve the cosmetic appearance of nails affected by fungus often consider Kerasal Fungal Nail Renewal. While not a cure, it serves as a cosmetic aid designed to restore a healthier look to nails affected by fungus.

This guide explores how Kerasal works, its benefits, limitations, and how it compares to other treatments.
Understanding Kerasal Fungal Nail Renewal
What is Kerasal Nail Renewal? Kerasal Fungal Nail Renewal is an over-the-counter topical treatment aimed at improving the appearance of nails affected by fungal infections. It is available without a prescription and is commonly found in pharmacies and online stores under names like Kerasal Nail and Kerasal Fungal Treatment.
Key Ingredients and Their Role:
- Propylene Glycol: Helps the formula penetrate the nail for deeper hydration and enhances the absorption of other active ingredients.
- Urea: Softens and thins the nail, allowing exfoliation of damaged keratin layers and making it easier for other ingredients to work effectively.
- Lactic Acid: Aids in breaking down thickened nail tissue and improving nail texture while reducing discoloration.
How Does Kerasal Work? Kerasal interacts with the nail structure by softening the outer keratin layer and allowing hydration to penetrate deeper. This process helps improve nail flexibility and reduces the appearance of damage. However, it does not eliminate the fungal infection itself.
Benefits of Using Kerasal
- Improved Nail Appearance: Users may see up to a 70% reduction in discoloration within 2-4 weeks, according to some reports.
- Softens and Hydrates: Helps brittle, damaged nails regain flexibility, reducing cracking and breaking.
- Easy Application: Comes in a simple tube with an applicator, requiring just a thin layer on affected nails.
- Readily Available: No prescription needed; available online and in most pharmacies.
- Compatible with Other Treatments: Can be used as an additive treatment alongside antifungal medications but should not be the sole treatment in most cases.
Limitations and Potential Drawbacks
- Not a Cure: Kerasal does not eliminate fungal infections, only improves nail appearance.
- Time for Results: While some see changes within weeks, full improvement may take months.
- Not for Severe Cases: Deep infections may require oral antifungals or prescription treatments.
- Possible Side Effects: Some users report mild irritation, such as redness, itching, or slight burning at the application site.
- Does Not Stop the Spread: Kerasal will not prevent the fungal infection from spreading to other nails.
- Limited Nail Penetration: The product does not reach the nail bed where fungal infections reside.
How to Use Kerasal Nail Renewal
Step-by-Step Application Guide:
- Prepare the Nail: Trim and file the affected nail using a fine-grit nail file or emery board to remove excess thickness.
- Apply the Product: Use a thin layer of Kerasal across the entire nail surface and underneath the tip if possible.
- Let It Absorb: Allow the product to dry for a few minutes before putting on socks or shoes.
- Use Consistently: Apply once daily, preferably before bedtime.
- Maintain Hygiene: Keep feet dry and wear breathable footwear to support nail health.
