This section is about nails and the skin around them. It covers products aimed at fungal nail infections and at brittle, splitting or discoloured nails, along with related skin products such as foot creams and balms. You will see oral capsules, topical serums and drops applied with a brush or dropper, nail oils, creams and soaks. Oral supplements for general skin concerns such as dryness or ageing are covered separately under Skin Health.
Thick, yellowed or crumbly nails are often blamed on fungus, but other problems can look very similar, including psoriasis and damage from injury. A doctor or podiatrist can confirm what is going on, sometimes by testing a nail clipping. That matters, because a product aimed at fungus will do nothing for a nail problem that is not fungal.
If you have diabetes, poor circulation or a weakened immune system, foot and nail problems deserve prompt medical attention rather than home experiments. The same applies to redness, swelling, pain or pus around a nail.
Nails grow slowly, and toenails grow more slowly than fingernails. Even when a treatment is working, the damaged part of the nail has to grow out, so visible change usually takes many weeks and a fully clear nail can take months. Fungal nail infections are known for being stubborn and for coming back. Any product that promises quick results deserves suspicion.
It helps to know the difference between approaches. Topical products have to reach the infection through or around a hard nail plate. Prescription oral antifungal medicines work differently and need a doctor’s supervision. Supplements marketed for nail health are something else again: in the US they follow the FDA’s rules for supplements, not the approval process for medicines, and they should not be confused with medicines.
Patch test any topical product on a small area of skin first, and stop if irritation develops. Oral products can interact with medicines, so speak to a doctor or pharmacist if you take regular medication, are pregnant or breastfeeding, or have liver, kidney or other long-term conditions.
When we review a nail product, we look at what it contains, how it is meant to be used, what the evidence says about those ingredients, and whether its timeline promises are realistic. The full process is set out in our methodology.
