Tips for successful treatment: to achieve faster and better results, it is recommended to carefully file the fungal nail once a week. If the treatment is interrupted, the nail fungus returns faster. It is therefore important to continue using the Health Press nail fungus solution until the nail fungus has completely disappeared.
Scientifically proven: the nail fungus solution helps in the treatment of nail fungus (onychomycosis) and has been proven to act against fungi that cause nail fungus. * It is suitable for the treatment of fungal nail infections on hands and feet in adults as well as diabetics.
PREVENTION & CARE Since humid environments are one of the causes of nail fungal infections, it is recommended to wear socks that are made only of moisture-absorbing materials such as cotton or wool. This is important as fungi are commonly found in humid environments where they can reproduce. If you have a nail fungus, it is important that you keep your feet dry. Disinfect nail scissors and files. Use a separate towel for your feet.
Made in the EU: the Health Press nail fungus is made in the Netherlands. All effect-related statements have been tested in accordance with the requirements of the EU Regulation for Medical Devices and have been proven accordingly. In addition, the nail treatment has been dermatologically tested by Dermatest GmbH and awarded the result "very good".
Effect: Thanks to a unique combination of active ingredients ISK1320, the Health Press nail fungus solution forms a protective layer on the nail, which creates a slightly acidic environment, which is unfavourable for the growth and spread of fungi.
Application information: The liquid treatment is intended for external use only. Wear the product 2 to 3 times a day (e.g. morning and evening) on the affected area until the mushroom nail has grown out completely. If necessary (if no improvement occurs), the nail fungus solution can also be combined with the intake of oral antifungal agents.
