Court Judgment Reaffirms Rules on Advertising of Medical Facilities in Thailand

Subscribe to Updates

On August 5, 2026, the Consumer Case Division of Thailand’s Civil Court rendered a judgment in a case involving a beauty clinic that advertised acne scar treatments using claims that the clinic was operated by a specialist physician and that the treatment, allegedly involving stem cell technology, could permanently remove acne scars.

The plaintiff brought a claim against both the physician-owner and the clinic company, alleging that the advertisements were false and induced her to purchase the treatment. The court found that the clinic was liable for the false representations and that the physician-owner, as both the authorized director of the company and the medical practitioner who provided treatment, was jointly responsible.

Although the plaintiff could not fully prove all damages claimed, the court awarded compensation of THB 20,000, together with interest.

While the judgment arose from a consumer protection dispute, it serves as a valuable reminder that medical facility advertisements in Thailand are regulated and may expose clinics and healthcare providers not only to regulatory enforcement but also to civil liability from patients who rely on misleading promotional claims.

Regulatory Framework Governing Medical Facility Advertisements

Medical facility advertising in Thailand is governed by the Medical Facility Act B.E. 2541 (1998), as amended by the Medical Facility Act (No. 4) B.E. 2559 (2016).

The principal secondary legislation is the Department of Health Service Support (DoHSS) Notification Re: Rules, Procedures, Conditions, and Fees for an Advertisement or Publication Concerning a Medical Facility, which came into force on November 25, 2019. Under this notification, “advertising” includes any act, by any means, that causes members of the public to see, hear, or otherwise become aware of a message, sound, or image for the commercial benefit of a medical facility. This broad definition covers not only traditional media but also clinic websites, social media, and other digital marketing channels.

Prior Approval Requirement

Section 38 of the Medical Facility Act requires medical facilities to obtain approval from the DoHSS before publishing any advertisement relating to the facility.

The only statutory exception is where the communication contains solely the medical facility’s name and location exactly as stated in its license.

Section 38 also expressly prohibits advertisements containing false, exaggerated, deceptive, or misleading statements—regarding the medical facility’s name or location, the medical services offered, the qualifications of healthcare professionals, or the competence or capabilities of healthcare personnel—that are intended to induce individuals to use the facility’s services.

The recent acne scar treatment case demonstrates the risk associated with claims that promise specific results, represent a doctor as possessing special expertise without adequate substantiation, or suggest that a treatment can permanently cure a condition.

Advertisements Exempt from Prior Approval

The 2019 notification permits certain information to be displayed within the medical facility premises without obtaining prior approval, including:

  • Abbreviations, trade names, logos, and symbols
  • Qualifications of healthcare professionals
  • Service fees and pricing information
  • Patient rights information
  • Lists of medical services and operating hours
  • Medical and public health knowledge, research findings, and educational content (subject to prescribed warning statements)
  • Announcements concerning facility activities, relocation, destruction of records, or commemorative events

Advertisements That May Be Approved

Advertisements outside the exemption categories require approval before publication. The DoHSS may approve advertisements that contain the following promotional elements, provided specific conditions are met:

  • Free medical services. Advertisements promoting free services must clearly state the date and time, the location, and the scope of the services offered.
  • Gifts, exchanges, benefits, prizes, or lucky draws. These may be offered only if the service recipient is the direct beneficiary and the medical service provided is not below the general standard.
  • Discounts on non-medical services. These may be offered only if the service recipient is the direct beneficiary.
  • Discounts on medical services. These may be offered for a period of up to one year.

Application Procedures

The approval process depends on the location of the medical facility.

  • For facilities located in Bangkok, applications must be submitted to the Center of Healthcare Advertising Approval (CHAA) within the DoHSS. Applications may be filed in person or by post. According to the CHAA website, straightforward applications involving text or still images may be approved within approximately five to seven working days after complete documentation is submitted.
  • For facilities located outside Bangkok, applications must be submitted to the relevant Provincial Public Health Office.

Penalties for Noncompliance

Failure to obtain prior approval may result in a fine of up to THB 20,000 and an additional daily fine of up to THB 10,000 for failure to comply with an order requiring the advertisement to be removed.

Advertisements that are false, exaggerated, deceptive, or misleading carry more severe penalties: imprisonment of up to one year, a fine of up to THB 20,000, or both. Additional daily fines of up to THB 10,000 may also be imposed until the offending advertisement is withdrawn.

Increased Enforcement Against Repeat Offenders

According to recent statements from the DoHSS, enforcement against repeat offenders is becoming increasingly stringent. The department reportedly applies an escalating penalty approach:

  • First violation: approximately 25 percent of the maximum fine
  • Second violation: approximately 50 percent
  • Third violation: approximately 75 percent
  • Fourth violation: referral for criminal prosecution

Importantly, the authority currently considers each advertising platform separately. In other words, violations are generally assessed by channel rather than by the number of individual posts. However, authorities have indicated that future enforcement may consider each prohibited claim separately, potentially increasing exposure significantly, including the risk that serious or repeated violations may give rise not only to civil claims but also to criminal complaints or prosecution.

The DoHSS is also reportedly considering introducing informer reward mechanisms for advertising violations, although the proposal remains under review. If adopted, such mechanisms could further increase the likelihood of complaints being filed, including potential criminal complaints in cases involving false, exaggerated, deceptive, or misleading advertising.

As enforcement activity continues to increase, the distinction between aggressive marketing and unlawful advertising is becoming increasingly important. A misleading claim may not only result in regulatory penalties but may also expose the clinic, its directors, and treating healthcare professionals to civil claims from dissatisfied patients and, where the facts support it, to criminal complaints or prosecution under the applicable statutory framework.

On June 17, 2026, Indonesia’s National Agency of Drug and Food Control (BPOM) issued BPOM Regulation No. 10 of 2026 on Nutritional Information on Processed Food Labels. The new regulation, which revokes three previous nutrition labeling regulations, introduces several notable changes affecting food and beverage manufacturers, importers, and distributors. These changes range from updated nutrient reference values and serving-size requirements to the introduction of the Nutri-Level front-of-pack labeling system for certain beverage products. Businesses operating in Indonesia should carefully review these developments and assess their products’ compliance with the new requirements during the transition period. Implementation of the Nutri-Level Labeling System To implement the recently issued decree on Nutri-Level labeling, BPOM Regulation No. 10 of 2026 stipulates the requirements to implement the Nutri-Level labeling system on the front-of-pack. Under the new framework, ready-to-drink beverages, powdered beverages, and liquid or solid concentrates are required to display Nutri-Level labeling on the front label of their packaging. The Nutri-Level labeling system classifies products into color-coded levels A through D based on their sugar, sodium, and total fat content. The applicable Nutri-Level is determined based on the lowest level measured in the assessment of sugar, sodium, and total fat content. For products classified as level C or D, the Nutri-Level label must be accompanied by information on the relevant sugar, sodium, and total fat content per 100 ml of the ready-to-consume product. Products classified as level A or B may either display only the Nutri-Level designation or display the Nutri-Level together with the relevant nutritional information per 100 ml. Minimum Vitamin and Mineral Content Required for Declaration BPOM Regulation No. 10 of 2026 introduces a stricter threshold for the declaration of vitamins and minerals in the nutritional value information section (ING). Vitamins or minerals may only be declared if they are present at a

The drug registration process in Vietnam will be simplified, particularly for foreign applicants, following the recent issuance by Vietnam’s Ministry of Health (MOH) of a new circular that is expected to reduce administrative hurdles. Circular No. 32/2026/TT-BYT on the registration of drugs and medicinal ingredients (Circular 32) was issued on July 29, 2026, and will take effect on October 1, 2026, replacing Circular No. 12/2025/TT-BYT. Key provisions of the new circular are discussed below. Five-Year Data Exclusivity and Five-Month Public Disclosure Framework Circular 32 updates data protection guidelines by explicitly referencing Article 128 of the amended Intellectual Property Law, which sets out that new drugs supported by clinical trial data submitted for the first time will be granted a five-year data exclusivity period from the date of the initial marketing authorization (MA) approval. Subsequent applications that rely on the originator’s protected data will not be eligible for approval from the date of submission of the originator’s registration dossier until five years after the first MA is granted. Furthermore, in accordance with the new regulations, the regulatory authority must publicly disclose information on subsequent applications five months before the granting of MA, providing originator companies with an opportunity to exercise and enforce their intellectual property rights. Simplified Requirements for Foreign Legal Documents Circular 32 expands the circumstances under which legal documents issued by foreign authorities are exempt from consular legalization and authenticity verification requirements. Specifically, such documents may be exempt if the Drug Administration of Vietnam (DAV) is able to verify their authenticity directly through official electronic means, including written confirmation or email correspondence sent directly to the MOH by the competent foreign authority, or publicly accessible English-language databases maintained by recognized foreign regulatory authorities. In addition, the new circular permits the submission of electronic notarized copies of legal documents

As food innovation continues to accelerate, manufacturers are increasingly introducing ingredients derived from new sources, produced using novel technologies, or lacking a significant history of human consumption. While these innovations create new opportunities for the food industry, they also raise important questions regarding consumer safety. For this reason, many jurisdictions, including Thailand, the European Union, Australia and New Zealand, Canada, and Singapore, require a premarket safety assessment for novel food ingredients before they can be placed on the market. The objective of this assessment is to ensure that each ingredient is safe for its intended use and level of consumption, does not present toxicological, allergenic, microbiological, or nutritional concerns, and will not mislead consumers. Scientific authorities typically evaluate the ingredient’s identity, manufacturing process, composition, specifications, anticipated dietary exposure, toxicological information, nutritional impact, and history of use before determining whether it can be marketed. Against this background, the Thai Food and Drug Administration (FDA) recently took an important step toward improving regulatory transparency by publishing, for the first time, a consolidated public list of substances that have successfully completed the Thai FDA’s safety assessment process, including substances determined to be novel foods and those determined not to fall within the novel food category. The list identifies the approved substances, the corresponding manufacturers or importers, approval dates, and the approved conditions of use. Although the publication does not change the existing legal framework governing novel food approvals, it provides businesses with greater visibility into the Thai FDA’s regulatory precedents and the types of substances that have previously been accepted through the safety assessment process. The full announcement is available on the Thai FDA’s website. As the list is now publicly available, it also provides useful insight into the types of substances that have successfully completed the Thai FDA’s safety assessment process.

For businesses in Thailand’s regulated industries, the problem of “too many licenses” is one of the most familiar hurdles to getting a product to market. Take a simple example: importing the materials necessary to sell teriyaki chicken skewers. To legally do this, a business may need approvals from several different agencies—separate permits for the chicken (Department of Livestock Development), the dipping sauce (Thai FDA), the wooden skewers (Department of Forestry), and other ingredients, each under a different authority. This kind of overlap is often cited to argue for a “regulatory guillotine”—a systematic review to cut outdated or duplicative rules that slow investment and business activity. The Facilitation of Licensing and Public Service Consideration Act B.E. 2569 (2026) (Licensing Facilitation Act 2026) is Thailand’s most significant response yet to that concern. This article looks at the Facilitation Act 2026 through a life sciences and regulatory affairs lens—what it may mean for the manufacturers, importers, and distributors of food, drugs, medical devices, cosmetics, and similar products who routinely deal with several regulators to bring a single product to market. The Super License: One Approval Standing in for Many The reform with the clearest potential for regulated-product businesses is the law’s “super license” mechanism, referred to as a “main license” in the statute. Once a business obtains the main license for a regulated activity, it is automatically deemed to hold all related sublicenses issued by other agencies for that same activity, provided the activity has been designated as eligible in the Government Gazette. The Licensing Facilitation Act 2026 also creates a central application center, allowing applicants to submit a single application and pay all relevant fees at one point of contact, with the center routing the application to each agency through a shared information system. The potential benefits of this for businesses
