Dear All,
Spa system is using Microcurrent, 1 fountain gives out '-' charge, 2 fountain gives out '+' charge. All pre-treatment gel, body shaping gel, and nutriol hair treatment are with '-' charge, but treatment gel and line corrector are with '+'. As '-' '-' , '+' '+'rebel, now you know why need to use 1 or 2 fountain. However, if you use other gel or cream if they dont carry charge, or you dont know what charge it carries, how can you select 1 or 2 fountain. Better not take the risk to try on other gel la.
