This is the most targeted formula for people whose fungus has caused nail separation from the nail bed. The 25% undecylenic acid is delivered in an organic olive oil base that is thin enough to seep under the nail, and the grapefruit seed extract adds a secondary antimicrobial punch. Users with chronic, recurring infections consistently report that this is the only OTC product that reattached their nail and cleared yellow discoloration.

The oily base serves a dual purpose: it moisturizes brittle, thinning nails while carrying the active ingredient deep into the subungual space. You apply it sparingly with the brush—one drop massaged into the cuticle and lateral folds is enough. Multiple long-term users report using it for years as both treatment and maintenance prevention, which speaks to its tolerability.

The main drawback is the oily texture, which can feel messy if you apply too much. A few units have shipped with loose lids, so check the seal on arrival. The olive oil scent is mild and natural, not chemical.

Silka takes a dual-format approach that covers both the nail and the surrounding skin. The liquid comes with a precision brush applicator for delivering the antifungal directly under the nail, while the separate cream formula targets athlete’s foot and ringworm on the skin itself. This is the best choice when your infection has spread beyond the nail to the surrounding cuticles and toe web spaces.

The cream is formulated for fast-acting relief from the itching, burning, and cracking that often accompany fungal infections. Users report feeling relief on day one because the cream soothes irritated skin immediately while the liquid works on the nail plate. The “clinical-grade” description is supported by consistent high ratings from buyers who had failed with single-format treatments.

One limitation: because it’s a set, you have two products to manage daily, which may complicate the routine for some users. The cream is thick, so it doesn’t penetrate the nail—that’s the liquid’s job. Some Spanish-language reviews indicate mixed results, likely from inconsistent application.

VTROUY combines 25% undecylenic acid with tea tree oil in a formula that dries quickly and has a mild, natural scent rather than a strong chemical odor. The two-bottle package gives you enough product for the full treatment cycle, and users consistently report visible reduction in discoloration within the first week. One reviewer with a large stripe on their big toe saw half the fungus gone after one application.

The absorption speed is a major advantage—the liquid dries in around ten minutes, so you can apply it right before bed without worrying about residue on sheets. Users who had avoided oral antifungals due to liver and kidney concerns found this to be a safe, effective alternative. The dermatologist-tested claim is backed by real-world results from people who had tried other OTC products with no success.

The main caveat: consistency is everything. The users who saw rapid improvement applied it strictly twice daily without missing a day. If you skip applications, results will slow dramatically. The bottle size is 0.5 fl oz each, which still lasts months with sparing use.

OSIMOON offers a straightforward liquid solution with undecylenic acid for people who want a no-nonsense treatment. The brush applicator makes targeted application easy, and the formula is designed to penetrate beneath thick, brittle nails where standard creams fail. Users with severe, long-standing infections appreciate that the liquid actually reaches the subungual area.

The 30ml bottle is a practical size for a multi-month regimen, and the thyme-like scent is far more pleasant than typical antifungal odors. Multiple reviews confirm it works on nail fungus caused by trauma (like stubbing a toe or dropping something on the foot), which often creates an environment where fungus thrives inside dried blood pockets.

Some users note that the liquid can feel slightly sticky before it fully dries, so you need to give it a minute or two before putting on socks. The effect is gradual—don’t expect dramatic changes in the first few days, but consistent use over several weeks produces noticeable improvement in nail clarity and thickness.

V20 Vite 20 is a traditional antifungal cream recommended by nail salons for mild to moderate cases. If you’ve just noticed a small white or yellow spot on your nail and want a first-line topical, this is a reasonable starting point. It works well for fungal infections caused by trauma—one reviewer with dried blood under the nail saw new, healthy growth after consistent use.

The cream format is less targeted than liquid treatments because it has limited ability to penetrate under the nail plate. However, for superficial fungal infections or for use as a maintenance product after a more aggressive treatment, it serves its purpose. The 0.56-ounce tube is compact and easy to travel with.

This is not the right choice for thick, discolored nails that have been infected for years. Multiple users note that while it helps, the cream simply cannot reach deep enough to eradicate an established subungual infection. For those cases, you need a liquid film-former like the Baar or VTROUY options above.
