Restore the appearance of damaged, discoloured or fungal toenails with KeryFlex toenail restoration—a professional, non-invasive cosmetic treatment applied by a podiatrist. KeryFlex creates a natural-looking, flexible artificial nail with immediate results and no surgery or downtime. Learn how the treatment works, who it may suit, what to expect at your appointment, and how to care for your restored toenail.
What is KeryFlex?
KeryFlex is a professional, in‑clinic cosmetic nail restoration system that rebuilds the appearance of damaged, fungal, or traumatised toenails using a flexible, durable resin. This non-invasive treatment, available only through podiatrists, creates a natural looking artificial nail over the existing nail or nail bed, provided at least 15% of the natural nail is present for proper adhesion. Using a clinically developed resin and polymer formulation, the procedure delivers an immediate cosmetic improvement without surgery, downtime, or discomfort. The resulting KeryFlex nail is non‑porous, resilient, and allows healthy nail growth beneath it. It remains unaffected by acetone, nail polish, and detergents, offering a long lasting, natural appearance for individuals seeking restoration of nails affected by fungus, defects, or trauma.
Who is KeryFlex for?
KeryFlex is designed for people who want to improve the cosmetic appearance of toenails that no longer look or grow the way they should. It’s ideal when the nail bed is healthy enough to support a restoration, but the nail itself is misshapen, damaged, or cosmetically compromised.
Common reasons people choose KeryFlex:
- Trauma related nail changes: Crushed, split, or partially lost nails.
- Mild to moderate fungal involvement: When the goal is cosmetic improvement rather than cure.
- Nail dystrophies: Structural defects with a healthy underlying nail bed.
- Shape abnormalities: Spoon nails, horizontal ridges, brittle or splitting nails.
- Discolouration or thickening: When the issue is primarily cosmetic.
- Avoiding surgery: Suitable for patients who prefer non‑invasive options.
Important suitability considerations:
KeryFlex is a cosmetic restoration not a medical cure. Your podiatrist will assess whether the nail and surrounding tissues are healthy enough to support the resin and whether any underlying condition needs treatment first.
When KeryFlex is NOT appropriate:
KeryFlex should not be used in individuals with:
- Peripheral vascular disease.
- Arterial insufficiency.
- Peripheral neuropathy.
- Suspicious pigmented nail lesions.
- Ingrown toenails.
It should also be avoided in patients who are pregnant, nursing, or known to be sensitive or allergic to any of the resin ingredients.
If you experience any redness, itching, or irritation around your KeryFlex nail, please contact your podiatrist or foot care provider for advice.
What happens during a KeryFlex appointment?
A KeryFlex restoration is performed entirely in clinic and takes approximately 30 minutes, depending on how many nails are being treated and how much reconstruction is required. The process is comfortable, non-invasive, and designed to give you an immediate cosmetic improvement.
Step-by-step: how your new nail is created:
- Clinical assessment: Your podiatrist examines the nail, reviews your medical history, and confirms suitability.
- Nail preparation: The damaged nail is trimmed, filed, or gently burred back using clippers or an electronic file to create a clean, stable surface.
- Bonding + resin application: A bonding agent is applied, followed by layers of specialised resin and polymer that are sculpted to recreate the shape and thickness of a natural nail.
- UV curing: The resin is hardened under ultraviolet light to form a flexible, durable artificial nail.
- Shaping + finishing: The new nail is moulded, smoothed, and polished for a natural, aesthetic appearance.
- Aftercare guidance: Your podiatrist explains how to care for the restoration and arranges follow up or maintenance if needed.
