External-use warnings
The submitted label says the oil is for external use only, should not be swallowed and should not contact the eyes. Stop if skin irritation develops; do not exceed the recommended use, and keep it out of reach of children.
A mixture of essential oils, menthol and camphor can cause tingling, redness or irritation in some people. Natural ingredient origin does not rule out adverse reactions.
Allergy and special populations
Sweet almond oil and walnut oil are on the label. Consumers with known nut or botanical sensitivities should be cautious and seek clinical advice as needed. Pregnant or nursing individuals and people with medical conditions should ask a professional about suitability.
Avoid self-treatment of open wounds, severe inflammation or an undiagnosed foot condition. People with diabetic foot risk should be especially careful about filing and rubbing affected nails.
Regulatory and marketing statements
The seller says its facility is “FDA accredited.” That is seller wording; FDA facility registration is not equivalent to product approval. We do not describe Kerassentials as FDA approved or FDA endorsed.
A legally marketed topical treatment would need an appropriate indication and evidence. A botanical skincare label does not by itself demonstrate an FDA-cleared nail-fungus cure.
Questions worth checking with the seller
Before purchasing, verify the 15 mL bottle size, four-times-daily routine, your selected number of bottles, the exact checkout total, shipping fees, eligibility for promotional extras and the published 60-day return procedure. Keep records if you order.
