A good fit if you…
  • have discolored, thickened, or brittle toenails
  • have tried over-the-counter antifungal creams without lasting results
  • prefer a natural, plant-based topical over harsh chemical treatments
Ask a doctor first if you…
  • have a diagnosed fungal infection that needs prescription antifungal treatment
  • have very sensitive skin (a patch test is recommended before full use)
  • expect a fast fix; nails grow slowly and visible change takes weeks
Good to know: nails grow slowly, so most topical nail treatments, including this one, need weeks of consistent daily use before visible change shows. It is a cosmetic topical, not a substitute for medical evaluation of a diagnosed fungal infection.

This Kerassentials review covers what is inside, what the research says about the ingredients, how to use it, the price and where to buy it. Dealing with discolored, thick, or crumbly toenails can be embarrassing, especially if creams and home remedies have not given you lasting results. It is a topical oil sold in a dropper bottle, built around eight named plant oils and extracts.

What Is Kerassentials?

Kerassentials is a topical liquid formula sold in a dropper bottle, built around eight named oils and plant extracts. According to the official sales page, it is designed to support healthy-looking nails and the skin around them.

Unlike a prescription antifungal that treats an active infection, this is a cosmetic topical oil applied to the nail bed and surrounding skin as part of a daily routine. It is non-GMO and free of synthetic chemicals, according to the brand.

Kerassentials Ingredients List: What’s Inside Each Bottle

The official sales page names eight oils and extracts in the formula. Here is what it discloses about each one; the page does not list individual amounts.

The official sales page names all eight ingredients but does not disclose individual amounts or a total volume per application.

Does Kerassentials Really Work? What the Research Says

It is applied topically, directly onto the affected nails and surrounding skin. The oils are intended to sit on and around the nail bed, an area where fungus and bacteria can build up, while nourishing the surrounding skin. Several of the individual ingredients, particularly tea tree oil and undecylenic acid, have research behind their antifungal properties in general use, and the sales page cites published studies on individual ingredients like tea tree oil, lavender and vitamin E nail oils.

What to expect, and when

As with most topical nail treatments, results depend heavily on consistency: nails grow slowly, so visible improvement in nail appearance typically takes several weeks of daily use. There is no clinical trial cited on the finished formula itself, only on individual ingredients.

What this product is not

Kerassentials is a cosmetic topical oil, not a prescription antifungal or a treatment for a diagnosed fungal infection. If you have a confirmed fungal infection that has not responded to over-the-counter care, or the nail is painful, bleeding or severely damaged, see a doctor or podiatrist. For general, evidence-based information on nail fungus, see the American Academy of Dermatology.

Is It Safe? Side Effects and Who Should Avoid It

It is applied topically and is generally well tolerated. As with any product containing essential oils, a small skin patch test is recommended before full use, especially for people with sensitive skin.

Discontinue use if irritation occurs, and keep it out of reach of children. If you have a diagnosed medical condition affecting your nails or skin, consult a healthcare professional before starting any new topical product.

How to Use It (Application and Directions)

According to the official FAQ, the oil is applied daily, after showering, directly to the nail bed and surrounding skin. The sales page does not specify an exact number of drops per application.
