AI-Generated Faces Are Reshaping Advertising-But at What Cost?

For decades, celebrity endorsements operated on a simple premise: if a famous face appeared in an advertisement, there was likely a contract behind it. Artificial intelligence is rapidly disrupting that assumption. We’re in the age of AI-generated faces!

Advertising has always relied on audiences believing what they see. AI-generated faces are challenging that assumption for the first time at scale. AI is transforming celebrity culture through hyper-realistic clones, synthetic endorsements, and deepfake-powered advertising. What began as a creative experiment is evolving into a larger industry question around disclosure, ownership, and consumer trust.

This conversation is no longer theoretical. Advertisers are facing a challenge that extends beyond innovation: preserving credibility in an environment where seeing is no longer believing. It is already unfolding across social media, advertising, and entertainment worldwide. 

The question is, where does one draw the line between creativity and deception?

The rise of synthetic celebrities

AI-powered face cloning is becoming alarmingly easy. Low-cost consumer AI tools can now duplicate what once needed costly Hollywood CGI teams and weeks of post-production in a matter of minutes.  

With just a few publicly available photos or videos, AI can now replicate a celebrity’s face, voice, expressions, and even create fake endorsements or realistic lip-synced content. This has created a new category of synthetic fame: AI-generated celebrities.

Using publicly available photos and videos, these digital replicas can appear online within minutes. 

When advertising becomes indistinguishable from impersonation

Traditional celebrity endorsements rely on consent, compensation, and clear agreements between brands and talent. AI-generated likenesses challenge that framework by making it possible to create convincing promotional content without direct participation from the individual being depicted.

Anyone can now create and distribute an advertisement that uses a celebrity’s image or likeness without their consent, licensing, or direct engagement. 

The result is a new gray area where audiences may struggle to distinguish between an authentic endorsement and a synthetic recreation. This is where the term AI in Advertising begins to intersect with deepfake advertising. 

As deepfake technology becomes more sophisticated, the challenge is maintaining trust in advertising itself. And brands, creators, and even some actors are already experimenting with them, showing just how rapidly the technology is evolving.

For consumers, the issue is straightforward: if a celebrity appears to recommend a product, should that endorsement be assumed to be genuine? Increasingly, the answer may not be clear.

Some recent examples: 

In 2025, Scarlett Johansson publicly criticized a viral AI-generated video that used her likeness without permission, reigniting debates around AI consent and digital identity. 

Around the same time, Tom Hanks warned followers about fake AI-generated health ads using his face and voice to promote questionable diabetes “cures” online.

Who owns a digital likeness?

AI-generated likenesses have intensified longstanding questions around ownership, consent, and identity.

Celebrities became memes, GIFs, and the foundation of a viral internet culture long ago. However, with the advancement of artificial intelligence (AI), the scale of everything has changed dramatically. 

Why is it important for the ad industry?

Copyright, ethical, and commercial reasons all factor into it. More and more public figures are claiming that their faces, voices, and digital personas should be treated as intellectual property and protected accordingly. Courts around the country are beginning to listen. 

It’s worth noting that this issue goes far beyond a particular industry. More and more politicians, influencers, journalists, and content creators. And even private citizens can be impersonated using AI.  

Research has already indicated that thousands of publicly available deepfake models have been produced using identifiable people without their consent, raising alarm about issues such as privacy, exploitation, and digital identity. 

That’s what the trust issue associated with AI advertising is all about. 

The incidents shaping the conversation around AI likenesses

These are some of the most notable cases that have contributed to the current debate on the ethics of AI face cloners: 

Deepfake ads and the consent problem

CBS News reported that many social media companies began allowing deepfake “nudifying” advertisements to be posted on their platforms. Many of these ads promote tools for creating explicit fake images based on photos of real people. 

This has raised serious concerns around privacy, exploitation, and the ethical use of AI-generated content in advertising. 

Unauthorized AI performances raise new questions

There have been reports of many actors finding out about AI-created advertisements that put them in created sexualized situations that never occurred outside of their imagination. 

This is an illustration of how quickly the effects of AI manipulation are becoming apparent in the entertainment marketing world. 

Why marketers find synthetic celebrities appealing

AI-generated faces are unlikely to disappear from advertising. The economic incentives are simply too strong. Marketers are finding AI-generated celebrities to be an attractive option for their advertising efforts, such as: 

• cost savings compared to real endorsements 

• infinite variety/customization options 

• available 24 hours per day, 7 days per week 

• multilingual capability (allows worldwide audience reach) 

• scalability across various campaigns. 

Brands can find the “perfect” spokesperson without scheduling conflicts, scandals, or negotiations with talented individuals.

Yet those efficiencies come with a potential trade-off.

As consumers become more aware of synthetic content, brands risk creating the perception that convenience has been prioritized over authenticity.

The brand trust risks are harder to ignore

Authenticity has become one of the most valuable currencies in modern marketing. Consumers already distrust overly polished advertising.

Given Gen Z’s hyper-awareness of manipulation tactics, the use of synthetic advertising is likely to elicit more backlash than engagement. If audiences begin questioning whether endorsements are real at all, the emotional foundation of influencer and celebrity marketing weakens. 

For marketers, the question is no longer whether synthetic media will become part of advertising. It already has. The real challenge is determining how to use it without compromising the credibility that effective marketing ultimately depends on.

The industry’s real challenge: Balancing creativity and credibility

AI-generated faces can be used to experiment with creative processes. Filmmakers, advertisers, and artists will continue discovering new ways to incorporate synthetic media into their work. Some uses of this media will become commonplace. 

At the same time, though, the same technology can be exposed without proper disclosure, consent, or regulation. There is no doubt that AI-generated celebrities will go mainstream; they already have. 

The advertising industry has to focus on establishing ethical boundaries before people completely lose trust. When reality can be changed, marketing is not simply competing for attention but for credibility.

Cut to the chase

AI-generated celebrity content may be opening new creative doors for brands, but it is also pushing advertising into one of its most dangerous grey areas yet. As synthetic media becomes harder to detect, the industry’s biggest challenge will not be creating realistic campaigns; it will be preserving audience trust. 

What remains uncertain is whether the industry can establish meaningful standards around disclosure, consent, and accountability before consumer trust erodes.
