Kerassentials is a brush-on oil for nails and skin. The brand calls it a doctor-formulated blend and says its oils support healthy nails and skin. The routine is simple: brush it over the nail and work it into the cuticle. The label prints every ingredient, which makes it easy to see what you're using. Packs start at two bottles for $79 each, and the 6-bottle pack brings the price to $49 a bottle with free US shipping and three bonus e-books. It's a one-time payment, and the 60-day guarantee lets you send the bottles back even if you've opened them. Order from the official website, the only place the brand sells it.

What is Kerassentials, and who makes it?
Kerassentials is a liquid oil for nails and skin, sold in a 0.5 oz (15 ml) glass bottle with a brush applicator. The label describes it as a "doctor formulated blend for healthy skin and nails", and the brand says its special oils fight fungus resistance and support healthy nails and skin.
The formula brings together 17 ingredients, all printed on the label. Undecylenic acid comes first at 5%, followed by a long list of oils: sweet almond, organic flaxseed, tea tree, lavender, lemongrass, clove bud, manuka, jojoba, chia and walnut, plus aloe vera, vitamin E, menthol and camphor. The brand describes the formula as natural, plant-based, non-GMO and easy to use.
You apply it with the enclosed brush after a shower and as part of your day: coat the nail, then work the oil into the cuticle. Kerassentials is sold only through its official website, in packs of 2, 3 or 6 bottles, as a one-time purchase.
It's sold by BuyGoods (Wilmington, Delaware, United States). The official site names BuyGoods, a Delaware corporation at 1201 N Orange Street Suite #7223, Wilmington, DE 19801, as the retailer of Kerassentials, and your card statement shows "BuyGoods". The bottle label reads "Distributed by: Kerassentials, 19655 E 35th Dr #100, Aurora, CO 80011, USA", which is also the address for returns. Product questions and refund requests go to contact@kerassentials-product.com; order support runs through BuyGoods.
Who Kerassentials suits, and who should skip it
A good fit for
- Adults who want their toenails or fingernails to look clearer, smoother and healthier
- Anyone who prefers an oil with a fully printed ingredient list built around plant oils
- People who can keep a daily brush-on routine for about three months, the time the brand suggests
- Buyers who want to try it with a safety net: the 60-day guarantee accepts opened and even empty bottles
Skip it or ask a doctor first
- Children. The label says to keep the bottle out of their reach.
- Anyone allergic to tree nuts or to an oil on the label, since the formula includes sweet almond and walnut oils
- People who are pregnant, nursing, taking medication or managing a medical condition and haven't checked with their doctor first, as the brand advises
- Use near the eyes or by mouth. The label says it is for external use only.

Tea tree oil
Bottle label and sales pageA well-known essential oil from the Melaleuca alternifolia tree. The brand highlights it for its antifungal properties.
What research says: A 2022 systematic review of natural options for nail fungus found tea tree oil was the most studied of them, with 5 of the 17 clinical reports it gathered, and called the evidence so far preliminary. Source
Lavender oil
Bottle label and sales pageA fragrant essential oil. The brand says it protects nail keratin and supports the nails and skin.
Organic flaxseed oil
Bottle label and sales pageA seed oil the brand calls a superfood for the skin and says supports the skin's natural defenses.
Sweet almond oil
Bottle label and sales pageA light conditioning oil. The brand says it supports healthy nails.
Lemongrass oil
Bottle label and sales pageA citrus-scented essential oil that the brand includes to help keep nails and skin fresh and calm.

Nine more oils and extracts
Bottle labelThe label completes the list with mineral oil, canola oil, walnut oil, menthol, camphor oil, clove bud oil, jojoba oil, chia oil and manuka oil. These carry the formula, condition the nail and cuticle, and add a cooling feel.
Does Kerassentials work?
Kerassentials works on contact. The brush lays a thin coat of oil over the nail, and a cotton swab carries it into the cuticle and the skin at the edges. The brand says the oils and vitamins give the nail bed and the surrounding skin the support they need to rebuild and stay healthy, and it calls Kerassentials a complete formula that maintains nail health in more than one way.
The label leads with undecylenic acid at 5%, a fatty acid the brand says helps protect the nails. Tea tree oil is the natural option researchers have looked at most for nails: a 2022 systematic review of natural approaches to nail fungus counted five clinical reports on tea tree oil, more than for any other, and described the evidence as preliminary. Lavender, lemongrass, clove bud and manuka oils round out the essential oils, while almond, flaxseed, jojoba and aloe vera keep the nail and cuticle conditioned.
On timing, the brand says you may notice nails that look more alive and skin that feels soothed early on, with new growth showing within the first weeks. Its own help page gives a fuller picture: around 9 to 12 weeks to see results, with some people faster and some slower. Nails grow slowly, so plan for a routine of about three months.
To get the most from it, follow the label. Apply four times a day, twice in the morning and twice in the afternoon. Coat the nail with the brush, then use a cotton swab to work the oil into the cuticle. The brand also suggests gently filing the nail surface with an emery board first, so the oil absorbs more thoroughly. Clean, dry feet and fresh socks help the routine along.

How the refund really works
Every order is covered by a 60-day, 100% money-back guarantee, counted from the day your package is delivered. The written refund policy sets out four steps: check that you're inside the 60 days, email contact@kerassentials-product.com with "Refund Request" in the subject line, and send all the bottles back to 19655 E 35th Dr #100, Aurora, CO 80011, with the packing slip and a note with your name, email and order ID. The policy says it doesn't matter whether the bottles are opened or empty, as long as all of them come back. You pay the return shipping. The refund is processed within a few days of the package arriving, you get an email when it's done, and the policy gives 5 to 10 days for it to reach your statement.
Is Kerassentials legit or a scam?
Kerassentials is sold through its own website, and the order is handled by BuyGoods, a Delaware-based online retailer that processes the payment and provides order support by phone and online. The site publishes its shipping policy, refund policy and terms, and the bottle label carries a distributor address in Aurora, Colorado.
The store is clear about the things buyers ask first. Its help page says the purchase is a one-time payment with no recurring shipments or charges. US orders ship with tracking, and the shipping policy says you get the tracking email within 60 hours and delivery in 5 to 7 working days. The 60-day money-back guarantee starts at delivery and accepts opened bottles.
Three practical tips make the order smooth. Choose your pack first: the 6-bottle pack is the one highlighted on the page, and the 2-bottle pack adds $9.99 shipping. The SMS alerts box at checkout is optional and comes unchecked. And after you pay, the store may show optional extra offers; take only what you want and keep your confirmation email and packing slip, which the refund policy asks for.
