What Is Kerassentials?
Kerassentials is a topical oil that brings antifungal plant oils, aloe vera, vitamin E and 5% undecylenic acid together to support healthy nails and skin. It’s made for you if toenail itching and a foul smell have stayed for months, and the gels, creams and pills you tried gave you no real results.
Each 0.5 oz (15 ml) bottle holds what the label calls a “Doctor Formulated Blend For Healthy Skin and Nails”: 5% undecylenic acid USP, seven featured oils and extracts, and nine supporting oils, including clove bud and manuka.
Kerassentials is made in a facility that is FDA accredited and that tests its products regularly for safety and quality.
How Does Kerassentials Work?
Kerassentials works by giving your nails and the skin around them a steady daily supply of antifungal plant oils and undecylenic acid.
Scientists from the U.S. Centers for Disease Control and Prevention point to a common mistake: most people stop their antifungal treatment before the infection is fully gone and before a healthy nail has grown out. Stopping halfway only makes the fungus stronger. Over time, that leads to antifungal resistance, and the same treatment becomes much harder to rely on the next time.
Kerassentials supports healthy-looking nails and skin with that daily routine. Tea tree, lemongrass and lavender oils bring antifungal properties, while almond oil, flaxseed oil and aloe vera care for the skin. You apply the blend to the nail and work it into the cuticle 4 times a day, so the support keeps going through the weeks a healthy nail needs to grow out.
Tests show that Kerassentials takes around 9 to 12 weeks to show results. Some people see results faster, and others need more time.
How to Apply Kerassentials
- File the nail first. Gently file the nail surface with an emery board, so the oil can absorb more thoroughly.
- Coat the nail. Use the enclosed applicator to cover the nail with oil.
- Work it into the cuticle. Use a cotton swab to work the oil into the cuticle of each nail.
- Repeat 4 times a day. Apply twice in the morning and twice in the afternoon, with the first coat right after your shower.
- Keep going for 9 to 12 weeks. Kerassentials takes around that long to show results, and stopping early is the mistake the CDC warns about.
Kerassentials Ingredients
Kerassentials has 17 ingredients on its label: eight key ingredients, led by 5% undecylenic acid, and nine supporting oils and botanicals.

|---|---|
| Undecylenic acid USP (5%) | Helps protect the nails |
| Lavender oil | Helps protect nail keratin |
| Organic flaxseed oil | Supports the skin’s natural defenses |
| Almond oil | Supports healthy nails |
| Tea tree oil | Helps curb fungus growth |

Eight Key Ingredients
Undecylenic Acid (5%)
Undecylenic acid USP is the only ingredient with a stated amount on the label: 5%. It’s a beneficial fatty acid that helps protect your nails and helps guard against fungus. Its research on athlete’s foot runs from a 1977 study to a 2026 review.
Lavender Oil
Lavender oil (Lavandula angustifolia) helps protect nail keratin, the tough protein your nails are made of. It supports both your nails and your skin, and it adds its own antifungal strength next to tea tree and lemongrass oil.
Organic Flaxseed Oil
Organic flaxseed oil (Linum usitatissimum) is a superfood for your skin. It supports your skin’s natural defenses and helps with inflammation, so the skin around each nail gets care while the antifungal oils do their part.
Almond Oil
Sweet almond oil (Prunus amygdalus dulcis) supports healthy nails. In Kerassentials, it also helps guard your skin against infections and helps keep fungus in check.
Tea Tree Oil
Tea tree oil (Melaleuca alternifolia) brings strong antifungal properties and helps curb fungus growth on and around the nail. Researchers have studied it in a cream for toenail fungus (1999) and for athlete’s foot (1992).
Lemongrass Oil
Lemongrass oil (Cymbopogon citratus) is an efficient antifungal that also helps with inflammation. It works next to tea tree and lavender oil, so three antifungal oils work together in each coat.
Aloe Vera
Aloe vera leaf extract (Aloe barbadensis) soothes and moisturizes the skin and brings antifungal properties of its own. It comforts skin that feels dry or itchy while the stronger oils in the formula work on the nail.
Vitamin E (Tocopheryl Acetate)
Tocopheryl acetate is a stable form of vitamin E. It helps protect your skin and supports skin that ages well. A 2023 retrospective study looked at vitamin E, together with minoxidil, for nail growth disorders.
Supporting Oils and Botanicals
Nine supporting oils and botanicals complete the label, with no stated amounts: mineral oil, canola oil, walnut oil, menthol, camphor oil, clove bud oil, jojoba oil, chia oil and manuka oil. The Kerassentials FAQ names clove bud and manuka oil when it describes the formula.
Kerassentials Label
The label lists all 17 ingredients, with undecylenic acid USP (5%) first and manuka oil last. Each bottle holds 0.5 oz (15 ml), and the studies behind the ingredients are in the scientific references.
What Makes Kerassentials Different?
Kerassentials puts antifungal oils, skin-soothing aloe and 5% undecylenic acid into one bottle, so one routine covers your nails and the skin around them.
An Oil, Not a Pill
You apply it to the nail and the cuticle, right where you need it, instead of swallowing a capsule.
A Plant-Based Formula
It’s natural, built on plant ingredients, non-GMO and free of stimulants.
Easy to Use
The enclosed applicator and a cotton swab are all you need.
