My cousin in law had a similar encounter for milk treatment.. Her first trial was awesome so she signed for the entire package (she got the promo thru some radio promo).when she started on her package, her face starts to turn for the worse, with angry red little bumps.. It was worse than before she did the treatment.. The sales person told her every face reacts differently. At some point of her treatment she got quite angry n showed pictures of her "before" n "after" n they suggest she change treatment, which she did. The reactions died down but of cos her face cannot be spot free like before .. In between those sessions there is no fixed beautician to do her treatments n each time she go they will pressure her to upgrade.. Quite a bad encounter for her but she very chin chai so she did not publish any stories..
