You may experience the following temporary side effects:
Irritation, skin reddening (erythema), burning sensation, small blisters (vesiculation), and itching (pruritus). Wait until symptoms disappear completely before starting your next treatment.
Tingling and stinging sensations. Muscle numbness (paresthesia) may occur. Slight pain could be felt at the beginning of the treatment or after the polarity alternating sequence. If you feel any of the above side effects, reduce intensity during next treatment.
Increased sweating: After the first few treatments, you may experience an increase in sweating. This symptom will subside after a few treatments.
Small electric shocks during treatment: In very rare cases, a harmless electric shock may occur if treatment is interrupted suddenly. To avoid this risk, remove your hands, feet or underarm electrodes slowly.
Skin dryness: Skin may become dry, small lesions or scaling may occur. To reduce these symptoms, use a moisturizing cream after treatments.
