A number of Vietnamese artists have appeared in ads promoting feng shui eyebrow services, including People’s Artist Lan Huong, People’s Artist Thu Ha, Meritorious Artist Viet Anh, Meritorious Artist Nguyet Hang, Actors Doan Quoc Dam, Luong Thanh, Singer Duy Manh, and MC Thanh Bach.

Many artists advertise these services with unsubstantiated claims. For instance, Doan Quoc Dam stated that eyebrow tattooing can "change one's appearance and fate, attracting wealth and good fortune." Viet Anh claimed that after getting his eyebrows done, his "love life became smoother, always feeling happy, and no longer arguing with his girlfriend."

Lawyer Le Kim Xuyen from Tran Ba Hoc Law Firm told VietNamNet that the advertisements show signs of violating the 2012 Advertising Law, specifically Clauses 9 and 11 of Article 8.

Current law prohibits advertisements that are inaccurate or cause confusion about business capabilities, product or service provision, quantity, quality, price, utility, design, packaging, trademark, origin, type, service method, or warranty period of registered or announced products, goods, or services.

Using terms like “best,” “unique,” “top,” or similar phrases (e.g., "Top 1 in Vietnam," "exclusive," "advised in detail by the most knowledgeable feng shui master") without lawful supporting documents as required by the Ministry of Culture, Sports, and Tourism is banned.

"Advertising related to aesthetic services can easily lead to false or misleading claims for consumers. Whether intentional or not, and whether paid or unpaid, artists are still responsible for their actions," she said.

Video advertisements also show signs of promoting superstitious practices by containing claims like: "Feng shui eyebrow tattooing helps change fate, attract wealth, and bring good fortune"; "After getting eyebrows done, work and projects have been going smoothly"; "Eyebrows help improve love life, always feeling happy, and no arguments with the girlfriend".

According to Xuyen, current laws do not specifically address ‘superstition’, but Clause 1, Article 2 of the 2016 Law on Beliefs and Religions regarding the concept of "belief," says superstition can be understood as “believing in vague, unnatural things that lead to consequences for individuals, families, or communities in terms of health, time, property, or life”.

Thus, artists advertising aesthetic services as helping to "change fate, attract wealth, and bring prosperity" include unverified, vague claims that do not align with natural reasoning and can easily lead to financial loss or harm.

To avoid legal violations and protect their reputation, the lawyer advises celebrities to carefully review documents related to the advertising conditions of organizations, individuals, products, goods, or services; and to thoroughly research or consult lawyers to understand advertising regulations, especially prohibited acts.
