Unlike most of the products covered on this site, Kerassentials isn't something you swallow — it's a topical oil blend applied directly to nails and skin. It's aimed at people dealing with nail discoloration, brittleness, or general nail and skin concerns, and it leans entirely on essential oils rather than lab-formulated actives.

What is Kerassentials?

Kerassentials is a liquid oil formula applied topically, typically with the small brush applicator included in the bottle. According to the manufacturer, it's made in an FDA-approved, GMP-certified facility, is plant-based, and is free from GMOs, harsh chemicals, and stimulants. One bottle is generally described as enough for about a month of regular use.

Key Ingredients

What It's Meant to Support

Kerassentials is positioned around three main claims: helping address the appearance of fungal-affected nails, strengthening and nourishing nails and cuticles, and soothing surrounding skin. It's marketed as a long-term, gentle-use product rather than a one-time fix.

Good to Know

Tea tree oil and lavender oil both have general research behind their antifungal and antimicrobial properties, and undecylenic acid is a recognized over-the-counter antifungal ingredient — but the specific Kerassentials blend hasn't been independently clinically tested as a finished product. Topical essential oil blends can occasionally cause skin irritation in some people, so it's worth doing a small patch test before regular use. Kerassentials isn't a substitute for medical treatment of a diagnosed or persistent fungal infection — anyone with a severe, spreading, or long-standing infection should see a doctor or podiatrist.
