i've used many product but no obvious result untill i use CNI product. i use their cleanser and skin balance essense. It works! the first week already feel the difference. after 3 months, hardly c pimple anymore. i used it for around 3 yrs then i stop coz no more pimple. But after 1 yr my pimple comes again,then i go see doctor in General Hospital. the doctor gives antibiotics and benzoyl to apply at nite time. it's a lot better now. The doctor said if your father or mother are not suffer from pimple when they r young, then u can try to use skin product. However, if ur mother or father is having similar problem when they r young,then all of the product effect doesnt remain long. Once u stop, it comes again. so, find out the reason of ur pimple then choose the rite way to cure.
