Im 19 and i've always suffered from hand and feet excessive sweating which can be annoying when hand shaking. how can i prevent it? thank you.

Iontophoresis/BOTOX: It is unlikely that you can prevent this. So you can try to treat it with clinical strength antiperspirants. If this doesn't work you can try prescription strength antiperspirants that can be very irritating. Your other options are iontophoresis or Botox injections. Iontophoresis has a high success rate...Over 80%. See your dermatologist for further evaluation and treatment.
