Are you always hiding your feet?
Many adults feel embarrassed about their toenails, but few talk about it.
Dull, yellowish toenails
About a minute, 4 times a day
Nails you are happy to showIllustrative images of different people. Results vary.
Avoiding sandals
At the pool, at the beach or at a barbecue, you keep your socks and closed shoes on.
Nails you don't want people to see
One or more toenails look thick, dull or yellowish. When someone looks at your feet, you curl your toes.
Trying and giving up
You buy a cream or polish at the pharmacy, use it for two weeks, see no change and give up.
Toenails grow slowly, so any nail routine takes time, and many people stop too early. A routine you can keep has to be easy to repeat every day, and that is how Kerassentials was designed.
If a nail hurts or is spreading, or if you have diabetes or poor circulation, see a doctor or podiatrist first.
You want to wear sandals again without thinking about your toenails.
Kerassentials is a simple routine for your toenails and cuticles: about a minute at home, 4 times a day. Every order has a 60-day money-back guarantee.
How Kerassentials works
According to the manufacturer, the formula works in three parts: one main ingredient, a blend of oils and vitamins, and a routine you repeat every day.
5% undecylenic acid
The main ingredient. A fatty acid made from castor oil and used in many foot care products.
Oils and vitamins
Almond, flaxseed and jojoba oils, aloe vera and vitamin E help soften and moisturize the nail and the skin around it.
A daily habit
Nails grow slowly, so the formula is made for daily use, not for a single application.
This is how the manufacturer explains it. Kerassentials is a topical care product, not a medical treatment.

What studies say about Kerassentials' main ingredients
The brand lists many scientific references. The three studies below looked at ingredients that are in the bottle.
A study in Skin Appendage Disorders tested a nail oil made with vitamin E and essential oils on adults with mild to moderate nail fungus. The oil was well tolerated.
Alessandrini A, et al. (PubMed)A study in Scientifica tested lavender oil against the yeast Candida albicans and compared it with the drug clotrimazole. It was done in the lab, not in people.
Behmanesh F, et al. (PubMed)A review in the Journal of Essential Oil Research summarized the studies on tea tree oil and its antimicrobial and antifungal properties.
Yadav E, et al. (Google Scholar)These studies looked at single ingredients or at a different oil, not at Kerassentials itself. The official website shows a rating based on 14,576 reviews; this number is published by the brand. Results vary from person to person.
How to use Kerassentials
According to the label, use it 4 times a day: twice in the morning and twice in the afternoon.
File
Lightly file the surface of the nail with a nail file, so the oil can absorb better.
Apply
Brush the oil onto the nail with the applicator. Then use a cotton swab to rub it into the cuticle.
Repeat
The brand suggests using it after your shower, when it is easy to remember.

A good choice if you…
- are an adult with dull or brittle-looking toenails, or dry and rough cuticles
- are tired of hiding your feet in closed shoes
- prefer something you apply to the skin instead of a pill

Talk to your doctor first if you…

For external use only. Keep it away from your eyes, do not swallow it, and test a small amount on your skin first.
Choose your Kerassentials package
Toenails grow slowly. According to the American Academy of Dermatology, a toenail can take a year or longer to grow out completely. That is why a package for several months makes sense. The 3- and 6-bottle packages cost less per bottle and ship free in the US.
