Our verdict in short
Kerassentials is one of the easiest nail and skin care habits we have reviewed: a plant-oil formula you apply after your shower, built around oils such as tea tree and lavender that have been studied for their effect on the microbes that live on skin and nails. It is simple to stick with, the bigger packages are good value, and the 60-day money-back guarantee means there is very little risk in trying it. We are happy to recommend it as part of a regular foot and nail care routine.

What is Kerassentials and how is it meant to work?
Kerassentials is a topical oil blend that you apply to the nail bed once a day, after your shower, when nails and skin are clean and soft. It is designed as a daily care step rather than a quick fix, and the manufacturer suggests using it consistently.
The formula brings together plant oils with a long history of use in skin care, plus aloe vera, a stable form of vitamin E and undecylenic acid, a fatty acid found in many over-the-counter foot products. Several of these ingredients, including tea tree oil and undecylenic acid, have been looked at in published studies on skin and nail microbes.
Because it is a topical product, there is nothing to swallow and no pill routine to remember. If you like simple habits, this is an easy one to add.
Kerassentials ingredients: what each one does
Kerassentials lists eight named ingredients. The page describes them as high-quality oils and minerals; amounts are not published. Here is what each is there for and what we found.
| Ingredient | Why it's included | What the research shows | Evidence |
|---|---|---|---|
| Tea tree oil | Traditional skin-care oil with antifungal properties | In a double-blind trial of 117 people, 100% tea tree oil applied twice daily for six months performed comparably to a clotrimazole solution on toenails.[2] A separate trial tested 25% and 50% solutions for foot skin.[3] | Promising |
| Undecylenic acid | Fatty acid used in over-the-counter foot products | A double-blind trial of 103 people found undecylenic acid and tolnaftate had indistinguishable effects on athlete's foot, and both beat placebo.[4] | Promising |
| Lavender oil | Aromatic oil studied for activity against yeast and fungi | Laboratory work shows lavender oil has fungistatic and fungicidal activity against Candida albicans; this is lab research, not a trial in people.[5] | Emerging |
| Lemongrass oil | Plant oil traditionally used for its fresh aroma and cleansing feel | Included for its aromatic and cleansing qualities; we did not review a human trial of the oil on nails. | Supporting |
| Flaxseed oil (organic) | Skin-friendly plant oil rich in omega-3 fats | A moisturising carrier oil; used here to nourish skin around the nail. | Supporting |
| Almond oil | Gentle emollient oil | Softens and conditions skin and cuticles; a well-known carrier oil. | Supporting |
| Aloe vera | Soothing, moisturising plant gel | Widely used to soothe and hydrate skin. | Supporting |
| Tocopheryl acetate | Stable form of vitamin E | Commonly used in skin care to protect and condition skin. | Supporting |
Does Kerassentials work? What the research says
Kerassentials has not been put through its own clinical trial, so the research below is about its key ingredients. It is encouraging, and the picture is consistent:
- In a randomized, double-blind trial of 117 people with toenail problems, tea tree oil applied twice daily for six months gave results comparable to a standard clotrimazole solution, with about 60% of both groups showing clinical improvement.[2]
- Undecylenic acid performed on a par with tolnaftate, a well-known antifungal, in a 103-person double-blind trial, and both beat placebo.[4]
- Lavender oil showed antifungal activity in laboratory tests, which fits its traditional use in skin care.[5]
What this means for you: Kerassentials combines ingredients that each have a reasonable research story, in an easy daily format. The finished formula has not had its own clinical trial, and nails grow slowly, so plan on using it consistently for several months and keep up good foot hygiene alongside it.
Kerassentials price: which package is the best value?
These are the per-bottle prices shown on the official order page when we checked on October 29, 2026. The page does not state how many days each bottle lasts, so we compare cost per bottle.
| Package | Total | Shipping (US) | Supply | Per bottle |
|---|---|---|---|---|
| 2 bottles | $158 | $9.99 | 2 bottles | $79 |
| 2 + 1 bottles (most popular) | $207 | Free | 3 bottles | $69 |
| 3 + 3 bottles (best value) | $294 | Free | 6 bottles | $49 |
Which should you choose? The 6-bottle package is the best value at $49 a bottle, and it matches the manufacturer's advice to use the product consistently over several months. If you want to start smaller, the 3-bottle package also ships free in the US. Every package is a one-time purchase.
How the 60-day money-back guarantee works
Every order is covered by a 60-day money-back guarantee. The refund policy asks you to use the product for a few months where possible, but you can request a refund at any point in the 60 days:
- The 60 days start from the day your package is delivered.
- Email support with “Refund Request” in the subject line, with your full name and order details.
- Send back all bottles, used or unused, with the packing slip. Return postage is paid by you; a trackable method is recommended.
- Refunds are processed within a few days of the package arriving and usually appear on your statement within 5–10 days.
Helpful tip: put a reminder in your calendar for around day 50. That leaves time to review how you are getting on and still use the guarantee comfortably.
Orders are handled by ClickBank. ClickBank is the retailer, and its order support line (1-800-390-6035 at the time of writing) can help with any order question.

How to get the most out of Kerassentials
- Apply it after your shower, when nails and skin are clean and dry, as the official directions suggest.
- Be consistent. Nails grow slowly, so judge the routine over months, not days.
- Keep feet clean and dry, change socks daily and let shoes air out between wears.
- Wear breathable shoes and flip-flops in shared showers or pool areas.
- Take a photo of your nails now and again each month so you can see gradual changes.
Is Kerassentials safe? Side effects
Kerassentials is a topical plant-oil product with no stimulants, and it is applied to the nail bed rather than swallowed. As with any essential-oil product, skin sensitivity is the main thing to watch for.
- Do a small patch test first if you have sensitive or allergy-prone skin; stop using it if you notice irritation.
- If you have diabetes or poor circulation, are pregnant or nursing, or take prescription medicine, check with your doctor before starting.
- See a doctor or podiatrist for nails that are painful, swollen, discharging or spreading.
- Dietary supplements aren't reviewed by the FDA for effectiveness before sale, which is true of every supplement.[1]
How Kerassentials compares with other options
- Over-the-counter antifungal products: products with a single active ingredient, such as undecylenic acid or clotrimazole, have more published trials of the individual ingredient. Kerassentials' advantages are its plant-oil formula and the daily-care format.
- Prescription treatments: a doctor or podiatrist can offer stronger options for established infections, and a good daily routine can sit alongside professional advice.
- Home remedies: vinegar soaks and similar habits are cheap but unstructured. Kerassentials gives you one consistent product to use.
