Quick answer: The Kerassentials label says to apply it 4 times a day (twice in the morning and twice in the afternoon). Use the brush to coat the nail, then a cotton swab to work the oil into the cuticle. For better absorption, gently file the nail surface with an emery board first. Avoid your eyes, never swallow it, and stop if your skin gets irritated.

Tips to Get the Most From Any Nail-Care Routine
- Keep feet clean and dry; change damp socks
- Wear breathable shoes and rotate pairs so they dry out
- Wear shower shoes in gyms, pools and locker rooms
- Don't share nail clippers or files
- Treat athlete's foot on the skin, since it can spread to nails
- Disinfect or replace files and clippers you use on affected nails
These are standard foot-hygiene steps recommended by dermatologists. See the American Academy of Dermatology: Nail fungus treatment page for treatment options.
How Long Should You Use Kerassentials?
The seller recommends using Kerassentials for at least 3 months, and the 6-bottle package covers 180 days. Be realistic: toenails grow slowly, and the AAD notes that even after successful prescription treatment, a toenail can take a year or more to grow out fully.
Watch the refund window: refunds are only available within 60 days of delivery — shorter than the 3 months the seller recommends. Take photos on day 1 and around day 50 so you can decide in time.
Common Mistakes to Avoid
- Applying it to broken, bleeding or infected skin
- Getting it near your eyes, or swallowing it
- Using it on children without a doctor's advice
- Skipping a doctor visit when a toe is red, swollen or painful
- Expecting a thick, discolored nail to look clear within weeks
See a doctor or podiatrist promptly if…
the skin around a nail is red, warm, swollen, painful or draining pus; a nail is bleeding or lifting quickly; you have diabetes, poor circulation or a weakened immune system; or the problem is spreading. These need professional care, not a home oil.
