He said the store was on the brink of closing down before the frenzy, which he thinks will last a long time.
Meanwhile, online stores that sell Pehchaolin cream are also enjoying an unprecedented boom.
Figures from the official Pehchaolin online store showed that more than 2,500 tins of the cream have been sold in the past 30 days.
While the Shanghai-based company was unavailable for comment on Friday, the online customer service representative, who responded half an hour after the inquiry from China Daily because "there are too many customers waiting to be answered", said nine out of 10 customers asked about the same gift package given by Peng.
The owner of a store that specializes in selling made-in-Shanghai skin-care products on Taobao, China's largest online bazaar, who refused to be named, said she has enjoyed an "at least a 10 percent increase" in the past month.
"I cannot prove the increase is related to the visit of the first lady, but I believe the attention has pushed many people to be at least willing to try domestic beauty products," the store owner said.
Other made-in-Shanghai products are also benefiting from the interest, especially skin care brands such as Gongdeng almond cream.
