No to Fungus Nail treatment has been specially formulated for Nutrismartworld right here in the UK. We wanted something that adhered to the nail and did not need to be reapplied twice a day. Our formulation contains two tea tree oils that condition the nail and are known for their anti-viral, anti-fungal properties. The nail shellac is applied using a cotton wool bud - rather than dipping the same applicator back into the bottle each time, which may only lead to contamination and spread of more fungus over time. Made in the UK by one of the leading formulation houses.
