## Description

For nail care focused on fungal concerns, UAUKO’s brush-on treatment is formulated for both fingernails and toenails, including the areas around and under the nails.

The formula combines 25% undecylenic acid with tea tree oil and six other botanical oils. That gives your routine a targeted topical step, rather than an appearance-only product such as decorative nail polish.

Each pack contains two 0.5 fl oz bottles. A built-in brush makes it straightforward to apply the treatment along nail edges and around the cuticle.

## What stands out

This treatment is designed for use on both fingernails and toenails, so the same product can serve a broader nail-care routine. Its 25% undecylenic acid formula is paired with tea tree, jojoba, lavender, peppermint, apricot kernel, camphor, and bergamot oils. The combination brings a targeted nail treatment and a blend of botanical oils together in one brush-on product.

The formula also aims to improve the appearance of damaged, brittle, or discolored nails while addressing fungal concerns. That makes it a practical fit for someone who wants nail care to include both a targeted treatment step and attention to how the nails look. For a routine centered only on covering discoloration, a cosmetic polish takes a different approach, this product is designed to be applied around the nail and cuticle instead.

## Highlights

The brush applicator supports controlled placement along nail edges and around the cuticle, without requiring a separate applicator. The two-bottle pack provides the same treatment in both containers, making it easy to keep the product available as part of a regular routine. Its intended use on both toes and fingers offers flexibility when more than one nail area needs attention.

Buyers describe the treatment as easy to apply and mention improvements in nail appearance and a pleasant scent. Those comments reflect individual experiences, while the product’s stated use and application directions provide a clear basis for incorporating it into nail care.

## How to take care of it

Apply the treatment with the brush around the cuticle area and along the edges of the nail twice daily. Allow approximately five minutes for absorption after application. Following the same steps each time helps keep the application focused on the areas identified for use. The brush-on format suits a simple routine at home, whether you are caring for toenails, fingernails, or both.

## Should you buy it?

UAUKO is a suitable choice for shoppers looking for a brush-on nail treatment that combines 25% undecylenic acid with tea tree oil and a seven-oil botanical blend. Its use on both fingernails and toenails, straightforward twice-daily application, and two-bottle format make it easy to add a focused step to regular nail care. Choose it when you want a product designed for fungal nail concerns as well as the appearance of brittle or discolored nails.
