KeraFirm Pro Ingredients

Quick Answer

KeraFirm Pro names nine ingredients: Undecylenic Acid USP (5%), isopropyl palmitate, almond oil, flaxseed oil, tea tree oil, aloe vera, vitamin E, lemongrass oil and lavender oil.

Only the active ingredient carries a stated concentration. The other eight are named but not quantified.

What the label tells you, and what it does not

KeraFirm Pro names all nine ingredients on its brand pages, and one — the active ingredient — carries a specific, checkable concentration: 5% Undecylenic Acid USP.

The remaining eight ingredients are named but not quantified, which is common for the conditioning-oil portion of topical formulas in this category, though it does mean you cannot independently verify their individual strength.

All 9 ingredients, one by one

Contributes cleansing properties, helping maintain a fresh environment around the treated nail.

Worth knowing before you apply

People with sensitive skin are advised by the brand to patch test a small area first and discontinue use if irritation develops. Those with diabetes or circulation problems should consult a healthcare professional before treating any nail or foot concern.
