How ActiFresh works: ActiFresh is unlike any other foot odour product. It works dynamically with your body to eliminate the cause of foot odour - the bacteria. The acids created by the bacteria catalyse the ActiFresh formulation, creating an instantaneous and dynamic action that quickly and effectively stops the odour-causing bacteria. This dynamic action only occurs when bacteria are present. The more bacteria that develop, the harder ActiFresh works. This ensures it is effective for even the most severe cases of foot odour. How do I use ActiFresh? For best results, follow the directions carefully. ActiFresh can be used at any time, but for best results apply after washing or showering. Always apply to dry feet, spraying on both sides of the feet and between the toes. STEP 1 - treat foot odour Spray PediTech ActiFresh on to your feet once a day for a period of 7 days. STEP 2 - prevent odour returning Once STEP 1 is complete, apply ActiFresh about once a week to continue to protect against foot odour from returning. Spraying each foot 4 times per weekly treatment will allow a 100ml bottle of PediTech ActiFresh to last for up to 8 months.
