Verdict: a clearly labeled nail oil with a written 60-day guarantee, best for people ready to apply it 4 times a day for months.
Check Today's Price OFFICIAL SITE · FREE SHIPPING ON 3+ BOTTLES · 60-DAY GUARANTEEKerassentials in short: a topical nail oil from Kerassentials Company (Aurora, Colorado). Its label lists 17 ingredients, including 5% undecylenic acid, tea tree and clove oil, applied 4 times a day. Bottles cost $49 to $79 depending on the package, and the 60-day guarantee starts when your order is delivered.
The four badges above are the seller's own claims, shown on its page. We did not see the certificates, and a registered facility is not FDA approval of the product. The label itself says its statements have not been evaluated by the FDA, so you will not see "FDA approved" or "clinically proven" on this page.
Is Kerassentials Worth Trying? Our Quick Verdict
We score Kerassentials on five things you can check yourself on the official site. Each one counts the same.
All 17 ingredients are printed on the bottle label, and undecylenic acid is stated at 5%. The other amounts are not published.
The label spells out how to apply it, with an applicator included. Four applications a day is more effort than a once-daily product.
$49 a bottle on the 6-bottle package, about $1.63 a day, with free US shipping on 3 and 6 bottles.
Written 60-day policy counted from delivery, with numbered steps and a 5 to 10 day refund time. You pay return postage.
Company name, Aurora, Colorado address, support email and a toll-free order line (24/7) are published on the policy pages and the label.
4.5 + 4.0 + 4.5 + 4.5 + 5.0 = 22.5, divided by 5 = 4.5. The half point we hold back is explained in "Good to Know" below.
Kerassentials Pros and What's Good to Know Before You Buy
✓ Pros
- Full ingredient list printed on the bottle label, with undecylenic acid stated at 5%
- Clear directions on the label, with an applicator and cotton swab routine
- Nothing to swallow: it goes on the nail and cuticle
- Free US shipping on the 3- and 6-bottle packages
- $49 a bottle (about $1.63 a day) on the 6-bottle package
- Written 60-day guarantee with numbered refund steps
- Seller address, email and a 24/7 toll-free order line are published
- 3 free ebooks and a surprise gift on the 6-bottle package
Good to Know Before You Buy
- No trial of the finished product. The studies we found tested single ingredients or different formulas.
- One printed dose. Undecylenic acid is 5%; the other 16 ingredients have no published amount.
- BBB rating of F. 12 complaints in three years, explained in the BBB section below.
- Returns go by mail. All bottles go back at your own postage, and the guarantee runs 60 days from delivery while the seller suggests at least 3 months of use.
These four points are the reason Kerassentials scores 4.5 and not 5. We list them here once and explain each in its own section.
What Is Kerassentials?
The official page opens with the headline "These Special Oils Fight Fungus Resistance And Support Healthy Nails And Skin." That is the seller's claim. The page and the bottle label also say that the statements have not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure or prevent any disease, so we treat the marketing as marketing and focus on what can be checked.
Orders go through the official page and a ClickBank checkout. The page names ClickBank as the retailer, which means ClickBank handles the payment and order support, and Kerassentials Company handles the product, the label and the refund address.
Kerassentials Ingredients: What the Bottle Label Says

The 17 ingredients, in the order printed
| # | As printed on the label | What it is |
|---|---|---|
| 1 | Undecylenic Acid USP (5%) | A fatty acid used in over-the-counter foot and skin antifungal products. The only amount printed on the label. |
| 2 | Mineral Oil | A light, non-plant carrier oil. |
| 3 | Sweet Almond (Prunus amygdalus dulcis) Oil | Carrier oil. Comes from a tree nut. |
| 4 | Organic Flaxseed (Linum usitatissimum) Oil | Plant carrier oil. |
| 5 | Tea Tree (Melaleuca alternifolia) Oil | Essential oil with the most nail research on this list. |
| 6 | Aloe Vera Leaf (Aloe barbadensis) Extract | Plant extract, common in skin products. |
| 7 | Canola (Brassica napus L.) Oil | Plant carrier oil. |
| 8 | Tocopheryl Acetate (Vitamin E) | A stable form of vitamin E. |
| 9 | Walnut (Juglans regia) Oil | Carrier oil. Comes from a tree nut. |
| 10 | Menthol | Cooling compound from mint oils. |
| 11 | Camphor (Cinnamomum camphora) Oil | Aromatic oil from the camphor tree. |
| 12 | Clove Bud (Eugenia caryophyllus) Oil | Essential oil. |
| 13 | Jojoba (Simmondsia chinensis) Oil | Plant carrier oil. |
| 14 | Chia (Salvia hispanica) Oil | Plant carrier oil. |
| 15 | Lemongrass (Cymbopogon citratus) Oil | Essential oil. |
| 16 | Lavender (Lavandula angustifolia) Oil | Essential oil. |
| 17 | Manuka (Leptospermum scoparium) Oil | Essential oil from a tea tree relative. |
The sales page shows eight ingredient cards: lavender, flaxseed, almond, tea tree, lemongrass, aloe vera, vitamin E and undecylenic acid. The bottle label lists 17. The extra nine (mineral oil, canola, walnut, menthol, camphor, clove, jojoba, chia and manuka) are on the label, and the page's reference list cites research on clove, manuka, menthol, camphor, walnut and chia. Reviews that list only 8, or that list a different set, are mixing the two. Go by the label on the bottle you receive.
The eight ingredients the official page highlights
Undecylenic acid (5%)
The only dose printed. A common ingredient in drugstore athlete's foot products. Studied in nails only as part of a different, multi-step product.
Tea tree oil
The best-studied oil here. A 117-person trial used 100% tea tree oil for toenail fungus. Kerassentials does not say how much it contains.
Lavender oil
Showed antifungal activity in a lab test on Candida yeast. Lab results do not tell you how it behaves on a nail.
Lemongrass oil
A fragrant essential oil. The official reference list does not cite a study on it.
Sweet almond oil
A carrier oil that helps spread the other oils. It comes from a tree nut, which matters if you have a nut allergy.
Organic flaxseed oil
A plant oil. The official references for it are a general review of flax and a lab study.
Aloe vera
Soothing and common in skin products. In one lab test it slowed one mold but not Candida yeast.
Vitamin E (tocopheryl acetate)
A skin-care staple. The study the page cites for it followed a single patient with a different nail condition.
The other nine ingredients (mineral oil, canola, walnut, jojoba and chia oils, menthol, camphor, clove and manuka) are mostly carrier oils and aromatic oils. Clove and manuka have lab studies; menthol and camphor appear in a small study of a mentholated chest rub, covered in the next section.
What the Science Says About Kerassentials Ingredients (and What It Doesn't)
| Study | What was tested | What it does and does not tell you |
|---|---|---|
| Buck 1994, J Fam Pract PMID 8195735 |
117 people with toenail fungus used 100% tea tree oil or 1% clotrimazole solution twice a day for 6 months. | Culture cure was 18% with tea tree oil and 11% with clotrimazole; partial or full improvement was about 60% in both groups. Encouraging for tea tree oil, but it was used undiluted and Kerassentials does not publish its tea tree amount. (Not cited on the official page; we added it as the best trial of this ingredient.) |
| Alessandrini 2020, Skin Appendage Disord PMID 32021856 |
20 adults with mild to moderate nail fungus applied an oil of vitamin E plus lime, oregano and tea tree essential oils once daily for 6 months. | 78.5% reported complete cure at 12 months. It was a small open study with no placebo group, and oregano and lime are not on the Kerassentials label. |
| Rehder 2008, Foot Ankle Spec PMID 19825699 |
154 patients for one year using cyanoacrylate, undecylenic acid and hydroquinone, with repeated nail debridement. | Negative cultures in 100% of mild, 65% of moderate and 35% of severe cases, so results were better in milder disease. A pilot study of a different multi-step product, not of a simple oil. |
| Derby 2011, J Am Board Fam Med PMID 21209346 |
18 people applied a mentholated chest rub (Vicks VapoRub) to toenail fungus for 48 weeks. | 5 of 18 had a mycological and clinical cure, 10 had partial clearance, 3 had no change. Menthol and camphor are on the Kerassentials label, but this was a different product in a small pilot with no control group. |
| Lab-dish studies: clove (Chee 2007), manuka (Chen 2016), lavender (Behmanesh 2015), aloe (Saniasiaya 2017) |
Oils or extracts were tested against fungi grown in a laboratory, such as the skin and nail fungus Trichophyton rubrum (clove) and Candida yeast (manuka, lavender, aloe). | They show activity under lab conditions. A nail is a hard plate that is much harder to reach than a lab dish, and in the aloe test one fungus responded while Candida did not. |
| Williams 1991, Arch Dermatol PMID 2064401 |
Topical vitamin E on the nails of one patient with yellow nail syndrome. | Nail growth and appearance improved in that patient. Yellow nail syndrome is not a fungal infection, and the authors said more study was needed. |
What this adds up to
Tea tree oil has real, if modest, human data in nail fungus, and undecylenic acid is a familiar antifungal ingredient. The rest of the list leans on lab tests, carrier oils and general skin care. That mix is what you would expect from an oil blend, and it is why we describe Kerassentials as a routine worth trying with a guarantee, not as a proven treatment.
For context, the American Academy of Dermatology says prescription topical medications are for mild (and sometimes moderate) nail fungus and are usually applied daily for 48 weeks, and that a nail takes a year or longer to grow out completely, even after the fungus clears (AAD, nail fungus treatment). Judging any product in weeks is optimistic.
How to Use Kerassentials: The Label Says 4 Times a Day
- Apply 4 times a day. Twice in the morning and twice in the afternoon, as printed on the label.
- Coat the nail with the enclosed applicator.
- Work it into the cuticle with a cotton swab.
- Gently file the nail surface with an emery board so the oil can absorb more thoroughly (the label's "for best results" tip).
- Follow the cautions. For external use only. Avoid contact with eyes and do not swallow; if swallowed, drink water and seek medical attention. Stop if irritation occurs and do not exceed the recommended dose.
- Store it safely. Keep out of reach of children, do not use if the safety seal is damaged or missing, and store in a cool, dry place.
| Package | Bottles you get | Lasts |
|---|---|---|
| 2 bottles | 2 | 60 days |
| 2 + 1 (most popular) | 3 | 90 days |
| 3 + 3 (best value) | 6 | 180 days |
Supply lengths are the ones shown on the official page (one bottle = 30 days).
Who Kerassentials Is For, Who Should Skip It and When to See a Doctor
- You want to try a topical nail oil routine and a doctor has no objection
- You are comfortable applying it 4 times a day
- You can keep going for 3 months or more
- You like a written guarantee with numbered steps
- You will take dated photos and keep your tracking number
- You have a tree nut allergy (sweet almond and walnut oils are on the label)
- You have diabetes, poor circulation or a weakened immune system
- The nail is very thick, painful, bleeding, or the skin around it is infected
- You are not sure it is fungus (nail psoriasis or an injury can look similar)
- You are pregnant or nursing, or take medication
- You expect results in days, or want drugstore pricing
Safety notes from the label and the seller
External use only. Avoid contact with eyes. If swallowed, drink water and seek medical attention. Keep out of reach of children.
Irritation. The label says to discontinue use if irritation occurs. Essential oils such as tea tree, clove and lemongrass can irritate sensitive skin in some people. If your skin is sensitive, ask a pharmacist how to test a small area first.
Tree nuts. Sweet almond oil and walnut oil are both on the label, and the seller does not say how they are processed.
Medical conditions. The seller's own site says to consult a physician before use if you are pregnant, nursing, taking medication or have a medical condition. Kerassentials is not a replacement for medical care.
When a doctor is the better first step
The American Academy of Dermatology notes that another nail condition, such as nail psoriasis or an injury, sometimes looks like nail fungus, and that a dermatologist can take a sample to confirm what you have. A doctor can also prescribe treatments with a defined course.
| Option | Typical course | Worth knowing |
|---|---|---|
| Kerassentials (oil, no prescription) | Label: 4 applications a day. Seller suggests 3+ months. | No published timeline or trial of the product. 60-day guarantee. |
| Prescription topical | Usually 48 weeks of daily application (AAD) | For mild (and sometimes moderate) cases. A doctor confirms the diagnosis first. |
| Prescription pills (terbinafine) | 12 weeks of pills for toenails (AAD) | Decided by a doctor, who can check for medication interactions. |
Course lengths for the medical options come from the AAD page linked above. This page is information, not medical advice.
Kerassentials Price and Packages
6 Bottles (3+3)
180-day supply
3 free ebooks + surprise gift · 60-day guarantee
Choose 6 Bottles| Package | Days | Per bottle | Total | US shipping | Cost per day |
|---|---|---|---|---|---|
| 2 bottles | 60 | $79 | $158 | +$9.99 | ~$2.80 |
| 3 bottles (2+1) | 90 | $69 | $207 | Free | ~$2.30 |
| 6 bottles (3+3) | 180 | $49 | $294 | Free | ~$1.63 |
Prices as shown on the official Kerassentials page on October 14, 2026, in US dollars. Cost per day is the total divided by the days supplied and includes shipping on the 2-bottle package. The seller's shipping policy table lists US shipping as free, while the order page shows $9.99 on the 2-bottle package, so always go by the final total on the checkout screen. The ebooks on the 6-bottle package are titled Skin SOS, Barefoot Ready and The Fungal Full Detox Plan. One thing to plan for: the 6-bottle package lasts 180 days but the guarantee covers 60 days from delivery, so decide inside that window.
What Happens After You Click: Checkout, Shipping and Support
- Choose a package. Our buttons open the official Kerassentials page at the packages section, so you can pick 2, 3 or 6 bottles.
- Pay on the ClickBank checkout. Order self-service is at clkbank.com, and the toll-free order line is 1-800-390-6035 (24/7).
- Read each screen. We did not place an order, so we cannot tell you what appears after you press buy. The official page shows no subscription. One BBB complaint from September 2024 describes being pushed to add more products, so read each button before you click.
- Look for the tracking email. The shipping policy says it arrives within 60 hours of ordering, with a link to follow your package. Save it: you will want the delivery date for the guarantee.
- Delivery. 5 to 7 working days in the United States, according to the shipping policy.
- Support. Product questions go to contact@kerassentials-product.com. International callers use +1 208-345-4245.
The Kerassentials 60-Day Refund, Step by Step
This is the seller's refund policy page (kerassentials.com/help/refunds.php), put in plain steps:
- Check your 60 days. The clock starts the day the order is delivered to you. Use the tracking number on the carrier's website to confirm that date.
- Email support at contact@kerassentials-product.com. Say you are not fully convinced by the benefits and put "Refund Request" in the subject line so it gets priority.
- Mail back all the bottles and the packing slip to Kerassentials, 19655 E 35th Dr #100, Aurora, CO 80011, USA. Opened or empty does not matter. Add a note with your full name, email and order ID.
- Pay the return postage. The policy says the company does not support return shipping costs.
- Wait 5 to 10 days. The refund is processed shortly after they receive your package, they email you when it is done, and your bank decides how fast it appears on your statement.
Why the 60-day window matters
The seller itself recommends at least 3 months of use before judging results, yet the money-back window is 60 days from delivery. That gap is the number one thing to plan around. If you want the guarantee to protect you, decide by roughly week 8 using your dated photos, not after the last bottle of a 6-bottle package.
Kerassentials BBB Rating Explained: What the Complaints Actually Say
We read the complaints and sorted them by theme. A complaint can fit more than one theme, so the counts are approximate, and the BBB shows the full text of each.
| What customers reported | About how many of 12 | What it tells you |
|---|---|---|
| "It did not work" after months of use (6 to 18 bottles) | ~7 | Results are not guaranteed, and long use without photos leaves nothing to compare. |
| Refund refused or late because the 60 days had passed | ~5 | The most avoidable problem: the window runs from delivery. |
| An unintended or extra order, or pressure to buy more | 3 | Read every checkout and upsell screen before clicking. |
| Slow or scripted customer service | ~3 | Keep emails and tracking numbers for every step. |
| Wrong product received | 1 | Check the label when the bottle arrives. |
| Skin irritation | 1 | Resolved with a refund after the bottles were returned. |
Of the customer reviews we read (16 of the 26), 15 were one star and one was five stars. No complaint or review we read mentions double billing or a subscription. These are customer statements that the BBB does not verify.
What this means for you. The pattern points to two things you control: expectations and timing. Several people used the oil for many months and asked for money back after the window closed. Buy from the official page, use the guarantee window on purpose, and you avoid the most common complaint. You can read the profile yourself on the BBB page for Kerassentials Company; the numbers may have changed since October 14, 2026.
Official Kerassentials vs Amazon, Walmart and Look-Alike Sites
Search results for Kerassentials include many look-alike sites with near-identical names, such as extra or swapped letters, and several review pages run by affiliates. A few checks tell you where you are:
| Check | Official Kerassentials | Be careful if you see |
|---|---|---|
| Address bar | kerassentials.com, then a ClickBank checkout | A similar domain with extra letters, hyphens or "official" in the name |
| Seller | Kerassentials Company, 19655 E 35th Dr #100, Aurora, CO 80011 | A different company or no address at all |
| Label | 17 ingredients, including undecylenic acid USP (5%) | A different ingredient list, or no label shown |
| Price | $79 / $69 / $49 a bottle for 2 / 3 / 6 bottles | Prices far from these, or packages you cannot match to the official page |
| Guarantee | 60 days from delivery, steps on the seller's refund page | A different guarantee, or none in writing |
Amazon and Walmart: third-party listings named Kerassentials appear on both. Their pages blocked our automated check, so we could not confirm who makes them or what is on their labels, and we cannot say they are the same product. We do not link to look-alike sites.
Kerassentials FAQ
Is Kerassentials legit or a scam?
It is a real, shipping product sold by Kerassentials Company of Aurora, Colorado, with a printed label, published contact details and a written 60-day refund policy, all checked October 14, 2026. It also has an F rating at the BBB and no clinical trial of the finished oil, so keep your expectations realistic and use the guarantee window.
Does Kerassentials work?
Nobody can say for sure, because no trial of Kerassentials itself exists. Tea tree oil, one of its ingredients, has small studies in nail fungus, and the American Academy of Dermatology says prescription topical treatments are for mild to moderate cases and are usually applied for 48 weeks. Take photos on day one and at day 60.
What are the ingredients in Kerassentials?
The bottle label lists 17 ingredients: undecylenic acid (5%), mineral oil, sweet almond oil, organic flaxseed oil, tea tree oil, aloe vera leaf extract, canola oil, vitamin E (tocopheryl acetate), walnut oil, menthol, camphor oil, clove bud oil, jojoba oil, chia oil, lemongrass oil, lavender oil and manuka oil. Only the 5% has a stated amount.
How do you use Kerassentials?
Apply it 4 times a day, twice in the morning and twice in the afternoon, according to the bottle label. Coat the nail with the enclosed applicator and work it into the cuticle with a cotton swab. The label also suggests gently filing the nail surface with an emery board. For external use only; avoid your eyes.
How long does Kerassentials take to work?
There is no published timeline for Kerassentials. The seller's refund page suggests at least 3 months of use, and the American Academy of Dermatology says a toenail can take a year or longer to grow out completely. The 60-day guarantee is shorter than that, so decide early using dated photos.
Does Kerassentials have side effects?
No side effect data has been published for Kerassentials. The label says to stop use if irritation occurs, for external use only and to avoid contact with eyes. Essential oils like tea tree and clove can irritate sensitive skin in some people. One BBB complaint described red, sore skin around three nails, resolved with a refund.
Can I use Kerassentials if I have a tree nut allergy?
The label lists sweet almond oil and walnut oil, both made from tree nuts, and the seller does not say how they are processed. If you have a tree nut allergy, ask your doctor or allergist before using Kerassentials. This is not a product to try first and ask later.
Can diabetics use Kerassentials?
Ask your doctor first. People with diabetes are generally advised to have any nail or foot problem examined by a doctor rather than treat it alone, and the seller's own site says to consult a physician if you take medication or have a medical condition. Kerassentials is not a replacement for medical care.
How much does Kerassentials cost?
On the official page, checked October 14, 2026: 2 bottles for $158 plus $9.99 shipping, 3 bottles (2+1) for $207 with free shipping, and 6 bottles (3+3) for $294 with free shipping. That is $79, $69 and $49 a bottle. The final total appears at checkout.
How does the Kerassentials refund work? Do I have to send the bottles back?
Yes. Within 60 days of delivery, email support with Refund Request in the subject, then mail back all bottles, opened or empty, with a note listing your name, email and order ID to the Aurora, Colorado address. Return postage is yours. The refund posts 5 to 10 days after they receive the package.
Does Kerassentials really have an F rating at the BBB?
Yes, the BBB profile showed an F rating on October 14, 2026, with 12 complaints in three years, the latest in November 2024, and 26 reviews averaging 1.15 of 5. Most complaints say the oil did not work or that the refund window had passed. They are unverified customer statements.
Is Kerassentials sold on Amazon or Walmart?
Third-party listings named Kerassentials appear on Amazon and Walmart, but we could not verify who sells them or what is on their labels. The 60-day refund policy we describe is written for orders placed on the official page, so that is the safer place to buy.
Is Kerassentials FDA approved?
No. The label itself says its statements have not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure or prevent any disease. The official page shows a badge for an FDA-registered facility, which is not approval of the product. Be cautious with any review that says clinically proven.
What do people say about Kerassentials on Reddit?
When we checked on October 14, 2026, we found no Reddit thread with customer reports about Kerassentials. The most detailed public customer accounts we found are on the BBB profile, which we summarize on this page. If you find a thread, treat it as one person's experience, not proof either way.
