After its large-scale recall announcement of flagship skin-whitening products Thursday, Kanebo Cosmetics Inc. has been inundated with phone calls from customers while retailers were busy removing the products from their shelves.

The cosmetics maker said it received 15,000 calls to a special toll-free service as of Thursday night after it was activated earlier in the day. The flood started after the firm announced in the morning it was recalling 54 products, including face lotions and emulsions, after it confirmed that some users' skin was marked with white patches.

Many of the customers who called the Kanebo hotline wanted to confirm whether the products they were using are subject to the recall. Others wanted to know whether any refunds would be forthcoming.
