On April 17, the Drug Administration, under the Ministry of Health, transferred a citizen's complaint dated March 25 regarding Chu Thanh Huyen's business activities to the local authorities for handling within their jurisdiction.

According to the complaint filed by a citizen identified as H., Chu Thanh Huyen allegedly sold OHUI PRIME cosmetics imported from South Korea without Vietnamese-language labeling, failed to issue sales invoices, and may have engaged in tax evasion. The sales were reportedly conducted primarily through her personal fanpage.

The Drug Administration determined that the matter falls outside its scope of responsibility and has therefore forwarded the complete dossier to the relevant local enforcement agency for further investigation and action.

In March, Chu Thanh Huyen also faced criticism for misleading advertising of a children’s product. The online personality repeatedly described the product as "milk," although it was actually a probiotic drink from South Korea. The beverage contains a combination of vitamins, minerals, fermented lactic acid bacteria, and extracts intended to support child growth and digestion.

Chu Thanh Huyen later issued a public apology, stating that her video lacked clarity and failed to emphasize that the opinions expressed were personal, which may have caused confusion.
