## Description

For a regular nail-care routine focused on the look of affected fingernails or toenails, Lakeim’s brush-on treatment offers a targeted way to apply care around the nail. Its formula contains 25% undecylenic acid and is designed for use along nail edges, around the cuticles and beneath the nail tip, as well as on nearby skin such as between the toes.

The set includes three 4 ml treatments and five nail files, giving you a ready-to-use format for ongoing care. Tea tree, jojoba, lavender and peppermint oils add a botanical element to the formula.

## Practical tips
The treatment is intended for consistent daily application as part of an ongoing nail-care routine. Brush it around the nail edges and cuticle, and under the nail tip, where buildup may appear. It can also be applied to nearby skin, including between the toes. The product is suitable for both fingernails and toenails, so the same approach can be used wherever nail care is needed.

A brush-on format helps direct the treatment to specific areas rather than spreading it broadly across the nail. Would this targeted application fit more easily into your routine than a product that needs to be rubbed in? The formula is described as lightweight and quick to absorb, while the included files offer a practical tool for nail care alongside application.

Buyers commonly describe the treatment as easy to apply and appreciate that it dries quickly. Some also report changes in the appearance of their nails with continued use, these are individual experiences, not a guaranteed timeline or result. Opinions on value are mixed, so the most relevant factors are the brush-on format, the 25% undecylenic acid formula and the three-treatment set.

## Tips for day-to-day use
Make regular application part of your nail-care routine and direct the brush to the nail margins, cuticle area and underside of the tip. Keep the application focused on the areas you intend to treat, including nearby skin if needed. Changes in nail appearance can take time as new nail growth gradually replaces damaged-looking areas, so the product is designed for steady, ongoing use rather than a one-off application.

The formula’s combination of undecylenic acid and botanical oils gives this treatment a distinct role in a routine centred on nail appearance and surrounding-skin care. The three 4 ml units also provide a multi-pack format for continued daily use.

## Before you decide
**Can it be used on fingernails as well as toenails?** Yes. The treatment is described for both, and can also be applied to nearby skin such as between the toes.

**Where should the brush-on formula be applied?** Apply around the nail edges and cuticle, and under the nail tip. The treatment may also be used on nearby skin.

**What is the active ingredient and concentration?** The formula contains 25% undecylenic acid, along with tea tree, jojoba, lavender and peppermint oils and a blend of seven natural oils.

## Should you buy it?
It makes sense if you want a brush-on nail treatment for both fingers and toes, with a clearly stated 25% undecylenic acid concentration and a formula that can be applied precisely around the nail. The three 4 ml treatments and five nail files suit a routine built around steady, targeted nail care.
