What is Kerassentials?
The world's first doctor-formulated antifungal nail oil with proven clinical ingredients
Kerassentials isn't just another over-the-counter nail treatment - it's a scientifically-formulated oil blend developed by retired MD Dr. Kimberly Langdon specifically to address the root causes of nail fungal infections. This comprehensive formula targets the fungus while simultaneously promoting healthy nail regeneration and protecting surrounding skin.
Unlike harsh prescription medications that can cause liver damage and other serious side effects, Kerassentials uses 9 carefully selected natural ingredients with proven antifungal properties. Each ingredient is chosen not only for its individual effectiveness but also for how it works synergistically with the other components.
The oil-based delivery system ensures deep penetration into the nail bed where fungal infections typically hide and thrive, something that traditional creams and topical treatments often fail to achieve effectively.
How it works
The Science Behind Professional-Grade Natural Antifungal Treatment
Step 1
STEP 1: Deep Penetration - The oil-based formula carries active antifungal compounds deep into the nail bed where fungal infections establish their strongholds, something water-based treatments cannot achieve effectively.
Step 2
STEP 2: Multi-Target Attack - Undecylenic Acid disrupts fungal cell membranes, Tea Tree Oil provides broad-spectrum antimicrobial action, and Clove Bud Oil delivers powerful antifungal compounds for comprehensive infection elimination.
Step 3
STEP 3: Infection Prevention - Lavender Oil and Lemongrass Oil create an inhospitable environment for fungal regrowth while providing anti-inflammatory benefits to reduce redness and irritation.
Step 4
STEP 4: Nail Restoration - Organic Flaxseed Oil and Sweet Almond Oil provide essential fatty acids and nutrients needed for healthy nail keratin production and structural integrity.
Step 5
STEP 5: Skin Healing - Aloe Vera and Vitamin E repair damaged skin around the nail, preventing secondary infections and promoting complete healing of the treatment area.
