Kerassentials Review: Does This Nail Fungus Oil Work? Our 4-Person Test

What is Kerassentials and what does it promise?

Nail fungus is one of those problems people hide instead of talking about. The nail turns whitish or yellow, sometimes dark at the edges, the cuticle looks dull, and suddenly sandals and the beach feel off-limits.

Kerassentials is a brush-on oil made for exactly that. It’s a small bottle with a brush in the cap, and you paint it onto the nail, the cuticle and the skin around them. The formula combines plant oils, aloe vera, vitamin E and undecylenic acid, a fatty acid used against fungus.

The promise: fight the fungus where it lives, protect the nail and the skin around it, and bring back clear, healthy-looking nails you’re comfortable showing.

To see if it delivers, we had four volunteers, each at a different stage of nail fungus, use it every day. Here’s how it went.

How does Kerassentials work on nail fungus?

Fungus settles into the nail and the skin around it, where it’s warm and often damp. That’s why a pill-free approach makes sense here: the oil goes straight to the spot.

The formula works on two fronts. Several of its oils, such as tea tree, lemongrass and lavender, are known for their antifungal properties and go after the fungus itself. The others, like flaxseed oil, almond oil, aloe vera and vitamin E, care for the nail and the skin so they can recover and stay protected.

Oil also has a practical advantage: it spreads into the edges of the nail and the cuticle, the places a cream can miss.

What’s in Kerassentials oil?

Kerassentials blends eight ingredients. Here’s what each one brings, in plain words.

• Lavender oil: protects the keratin that nails are made of and supports healthy nails and skin, while helping fight stubborn fungus.
• Organic flaxseed oil: a “superfood” for the skin that strengthens its natural defenses and helps calm inflammation.
• Almond oil: nourishes the nails and helps protect them against fungus and infection.
• Tea tree oil: one of the best-known natural antifungals, included to help curb fungus growth.
• Lemongrass oil: an efficient antifungal that also helps soothe inflammation and protect against new infection.
• Aloe vera: soothes and moisturizes the skin, with antifungal properties of its own.
• Tocopheryl acetate: a stable form of vitamin E that protects the skin and helps keep it looking younger.
• Undecylenic acid: a beneficial fatty acid that helps prevent fungus and protects the nails.

The formula is plant-based, non-GMO and free of stimulants.

Our experience: four volunteers, four applications a day

We ordered Kerassentials from the official website, and the box reached us two days later. The bottles came sealed, with nothing unusual in the packaging.

The oil has a mild herbal smell, nothing medicinal. The brush makes it very easy to apply, and a single stroke covers a nail, so the bottle lasts a good while.

Instead of testing it on one person, we asked four volunteers to use it, each with a different degree of nail fungus. Everyone followed the label’s directions: four applications a day.

Change came quickly. By day five, the whitish look around the cuticles was gone, and the whitish, darkened discoloration on the nails was clearly better. It took a bit longer for the nails themselves to clear: about two weeks of use until the discoloration was no longer visible.

None of the four had irritation, burning or redness. We didn’t need customer support. If we had wanted a refund, BuyGoods handles them, and in our experience their refund process is quick and free of red tape.

Who would we recommend it to? Anyone dealing with fungus on their nails or cuticles, especially people who’ve started avoiding open shoes because of it.

Did it live up to its promise?

Yes. It promises clearer, healthier-looking nails, and that’s what our volunteers got: a visible difference in five days and discoloration gone in about two weeks, with no skin reactions.

Keep in mind this was four people, not a guarantee. A deeper or older infection can take longer, and a nail only fully renews as it grows out, so staying consistent matters even after it looks good.

What are buyers saying about Kerassentials?

The stories shared on the official website describe nails that look clearer and healthier and people who feel confident going barefoot again. The site itself notes that those results aren’t typical for everyone.

When we looked for independent feedback, we mostly found copycat pages built around the Kerassentials name, along with “reviews” on those same sites. That doesn’t help a buyer much, and it’s one more reason to order only from the official page. As always, results differ from one person to the next.

Does Kerassentials have side effects?

Kerassentials goes on the skin rather than being swallowed, and it’s made from plant oils, aloe vera and vitamin E. Our four volunteers used it four times a day with no irritation, burning or redness.

A few common-sense precautions:

• If your skin tends to react to essential oils, test it on a small patch first.
• Use it on intact skin only, and keep it away from your eyes.
• If you’re pregnant, nursing, take medication or have a health condition, ask your doctor before starting.
• If you have diabetes or poor circulation, have any nail or foot change looked at by your doctor too.

How much does Kerassentials cost, and where can you buy it?

Kerassentials comes in three packages on its official website:

Package	Price per bottle	Total	Shipping
2 bottles	$79	$158	$9.99
3 bottles (2 + 1 free)	$69	$207	Free (US)
6 bottles (3 + 3 free)	$49	$294	Free (US)

The 6-bottle package costs the least per bottle and also comes with three free e-books, on skin comfort, nail regrowth and a full-body “fungal detox” plan, plus a surprise gift. The 3-bottle package includes the surprise gift too. Outside the US, shipping fees apply.

Every package is covered by a 60-day money-back guarantee. Payment and refunds are handled by BuyGoods.

Buy only from the official website. Kerassentials is a popular name, and lookalike sites and marketplace listings use it to sell copies whose contents nobody can vouch for. The real oil comes only from the official page, and only those orders are covered by the 60-day guarantee.
