Answers below state what is known (label facts, vendor-stated policy) and flag what is vendor-reported or unverified. Where a question has a whole page, we link it rather than compressing the nuance.

The five questions behind most searches
What is Kerassentials, in one sentence? A topical oil blend of eight named ingredients, marketed for healthy skin and nails, applied daily to the nail and surrounding skin — not a pill.
Does it work? There is no published clinical trial of the finished formula; individual ingredients carry laboratory and small-clinical evidence, and the closest analogous nail-oil study was encouraging but limited. The honest summary lives in how it works.
How much does it cost? $158 / $207 / $294 for the 2-, 3- and 6-bottle packages — $79, $69 and $49 per bottle — with free shipping on the larger two. The price page adds per-day math.
Where do I buy it? Only via the vendor's official website and ClickBank checkout; there is no verified Amazon, Walmart or store presence. The buying guide shows the genuine checkout tells.
What if it is not for me? A vendor-stated 60-day money-back guarantee covers every package; the guarantee page explains the process and its two timing traps.

Frequently Asked Questions
What exactly is Kerassentials?
A topical oil blend for skin and nails in a 15 ml bottle, marketed as a doctor-formulated blend of plant oils, vitamin E and undecylenic acid.
Is Kerassentials a pill or a supplement I swallow?
No. Despite the word “supplement” appearing in some searches, it is an external oil applied to nails and surrounding skin.
Does Kerassentials have a published clinical trial?
No. We found no published clinical trial of the finished formula. The vendor cites ingredient-level studies, which we analyze separately on our ingredients and how-it-works pages.
How long does one bottle last?
Based on the vendor’s package framing (2 bottles = 60-day supply), one 15 ml bottle is positioned as roughly a 30-day supply with daily use.
When might I notice changes?
Nails grow slowly — a full toenail replaces itself over many months. The vendor suggests early cosmetic changes within weeks; structural change depends on the nail growth cycle.
Can I wear nail polish while using it?
The vendor’s guidance is to let the oil absorb; avoiding polish during use is the sensible reading so the oil can reach the nail surface.
Who should not use Kerassentials without asking a professional?
People who are pregnant or nursing, treating a diagnosed nail or skin condition, taking relevant medications, or who have sensitive skin or essential-oil allergies should check with a clinician first.
Is Kerassentials FDA approved?
No. It is sold as a topical cosmetic-style blend, not an approved drug. The vendor states manufacturing follows GMP practices in an FDA-registered facility, which is not the same as product approval.
How much does it cost?
$158 for 2 bottles (+$9.99 shipping), $207 for 3 bottles (free shipping), $294 for 6 bottles (free shipping) — i.e., $79/$69/$49 per bottle at current vendor pricing.
Where is it sold?
Through the vendor’s official website and its ClickBank checkout. We found no verified official retail presence on Amazon, Walmart or in stores.
What if it does not work for me?
The vendor offers a 60-day money-back guarantee via its support team; our guarantee page walks through the process.
Does it ship internationally?
The vendor checkout we reviewed defaults to the United States; international availability, if any, is determined at checkout.
