Previously, Lao Dong Newspaper had a series of articles reflecting on the situation of weight loss pens of unknown origin being sold rampant on social networks. In the role of customers who need to buy products, reporters recorded many sellers using tricks to circumvent censorship to advertise, arrange direct transactions and distribute pens without Vietnamese sub-labels, and cannot present invoices and documents proving their origin.
Notably, some facilities still accept on-site weight loss injections in conditions that do not meet professional and hygiene requirements, posing many risks to users' health.
