What is Kerassentials?
Kerassentials is a topical oil formula developed by Dr. Kimberly Langdon to support nail and skin health, with particular focus on addressing the root causes of fungal nail infections. The formula combines 9 natural oils and minerals with antifungal properties that penetrate beneath the nail surface where standard topical treatments typically fail.
Nail fungus affects up to 14% of the general population and is notoriously difficult to treat. Kerassentials' oil-based delivery system allows active ingredients to penetrate the nail plate and surrounding skin, targeting the fungal biofilm directly — the protective coating that makes nail fungus resistant to standard treatments.

What's Inside Kerassentials?
Kerassentials uses a blend of 9 natural oils and mineral compounds, each selected for documented antifungal, antibacterial, or skin-supporting properties.
Lavender Oil
Essential oilContains linalool and linalyl acetate with documented antifungal activity against Candida and dermatophytes — the main fungi responsible for nail infections.
Organic Flaxseed Oil
Cold-pressedRich in alpha-linolenic acid (ALA) that supports skin barrier function and reduces inflammation associated with fungal nail infections.
Almond Oil
Sweet almond, cold-pressedA lightweight carrier oil rich in vitamin E that penetrates the nail plate effectively, softening brittle nails and delivering active antifungal compounds beneath the surface.
Tea Tree Oil
Melaleuca alternifoliaOne of the most studied natural antifungals. Terpinen-4-ol disrupts fungal cell membranes and has demonstrated efficacy against Trichophyton rubrum — the most common nail fungus pathogen.
Lemongrass Oil
Cymbopogon citratusContains citral and geraniol with proven antifungal properties. Also works as a natural preservative and supports healthy inflammatory response in nail tissue.
Clove Bud Oil
Syzygium aromaticumEugenol in clove oil has strong antifungal and antibacterial properties. Inhibits fungal biofilm formation — the protective coating that makes nail fungus so resistant to treatment.
Manuka Oil
Leptospermum scopariumAntimicrobial properties reportedly 20–30x stronger than tea tree oil against some fungal strains. Particularly effective against resistant nail fungus cases.
How to Use Kerassentials
Follow these instructions for best results. Consistency and correct timing are the most important factors in achieving desired outcomes.
- Apply 3–4 times daily using the included brush applicator
- Ensure the nail and surrounding skin are clean and dry before each application
- Apply generously to the entire nail surface, underneath the nail edge, and surrounding skin
- Best application times: morning, afternoon, evening, and before bed
- For best results, use for a minimum of 90 days — nail regrowth is gradual
Side Effects & Safety of Kerassentials
Kerassentials uses natural essential oils and is topically applied, making systemic side effects extremely unlikely. The formula does not enter the bloodstream in meaningful quantities. Most users tolerate it well with no adverse effects.
Skin sensitivity: essential oils (clove, lemongrass, tea tree) can cause irritation in those with sensitive skin. Perform a patch test on a small area before full application
Essential oil allergy (rare): if you are allergic to any botanical in the formula, discontinue use immediately
Avoid contact with eyes and mucous membranes: essential oil formulas should not contact sensitive areas

Frequently Asked Questions
How do you apply Kerassentials?
Apply the oil to affected nails and surrounding skin 3–4 times daily using the included brush applicator. Ensure the area is clean and dry before application. For best results, apply after showering and before bed. Consistency is essential.
How long does Kerassentials take to work?
Most users see initial changes within 6–8 weeks. Full clearance of severe infections typically requires 4–6 months. The 6-bottle package covers this full treatment window.
Is Kerassentials safe for diabetics?
The topical formula contains natural oils with no known systemic effects. However, diabetics at elevated risk for nail infections should consult their physician before using any treatment.
Can Kerassentials be used on fingernails?
Yes. Kerassentials is formulated for both finger and toenails. Fingernail fungus typically responds faster due to faster nail growth rate.
