Chemistry & Electricity第 86 / 100 题
An esthetician plans a galvanic desincrustation treatment. Which statement is correct?
a.Desincrustation uses the positive pole to force product into the skin
b.Desincrustation uses the negative pole with an alkaline solution to soften sebum and debris, making extractions easier
c.Galvanic current is safe for all clients, including those with a pacemaker
d.Desincrustation and iontophoresis are the same procedure
解析
Galvanic desincrustation uses the negative pole and an alkaline solution to saponify sebum and soften follicular debris before extraction, while iontophoresis uses matched polarity to drive water-soluble products into the skin. Galvanic current is contraindicated for clients with a pacemaker, metal implants in the treatment area, epilepsy, pregnancy, open lesions, or a lack of skin sensation.
