What the seller actually says
The support FAQ says people may experience results at different speeds and mentions an approximate 9–12 week time frame, while the sales letter includes more immediate-sounding claims. Both are promotional descriptions, not independently demonstrated averages.
The seller recommends three or more bottles for an extended routine. That is a purchase recommendation, not clinical proof that a particular duration or amount will resolve an infection.
Nail growth is relatively slow
A damaged toenail may take many months to grow out, even after an effective treatment addresses the underlying issue. A nail that looks unchanged after a brief period is not necessarily informative about the exact cause.
The American Academy of Dermatology describes significant timescales for diagnosed fungal nail treatments and notes that nails grow slowly. Its treatment discussion is not a Kerassentials clinical endorsement.
How to document changes responsibly
If you choose to use an oil cosmetically, note your starting condition and any changes in comfort, irritation or appearance. Avoid attributing every change to the oil without considering hygiene, other treatment or normal nail growth.
Persistent pain, spreading inflammation, drainage or diabetes-related foot issues deserve medical evaluation rather than repeated use based on a seller timeline.
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.
