AI is becoming increasingly integrated into everyday life. 

There’s been a notable amount of fake, AI-generated reviews across industries such as healthcare clinics, airlines, and even holiday shopping.

Further, there’s been a substantial increase in AI content in Google Search Results

As AI continues to impact numerous fields, we conducted a study to determine whether AI was present in health and wellness product reviews across key consumer industries — baby formula, skincare, and health supplements.

To conduct the study we analyzed a dataset of 11,263 product reviews

Objectives of the Study

  • Detect and analyze AI-generated reviews using the Originality.ai AI detection API.
  • Assess the prevalence of AI-generated reviews across product categories for baby formula, skincare, and healthcare supplements.
  • Evaluate the correlation between product popularity and consumer ratings.

Our research aims to assess the impact of AI reviews on consumer trust, and the ethical concerns surrounding their use. These are our findings.

Key Takeaways and Results (TL;DR)

  • 95.6% of health and wellness product reviews are Likely human-written.
  • 4.4% of health and wellness product reviews are Likely AI-generated.
  • AI-generated reviews are more prevalent in supplement products (6.66%) than in skincare products (5.27%) or baby formula (2.83%).
  • AI-generated reviews tend to have slightly higher star ratings compared to human reviews, although the difference is marginal.

95.6% of Health and Wellness Reviews Are Likely Human-Written

After conducting our analysis, we were pleasantly surprised.

Previous findings in our healthcare clinic review study demonstrated a substantial amount of AI reviews in healthcare clinics. 28.9% of U.S. plastic surgery clinic reviews and 20.7% of Canadian dental clinic reviews were detected as Likely AI-generated.

However, in contrast, there was a low level of AI in health and wellness product reviews.

Only 4.4% (494 reviews) of health and wellness products were Likely AI-generated.  

This means that the vast majority of health and wellness product reviews are still Likely human-written at 95.6% (10,769 reviews) — at least for now.

A Note on False Positives

The rate of AI healthcare reviews at 4.4% is so low that it falls within the typically normal range of false positives with AI detection.

False positives in AI detection occur when an AI detector identifies original, human-written content as AI-generated.

At Originality.ai, our Lite model offers an under 1% false positive rate. Then, our Turbo model has an under 3% false positive rate.

So, in this context, 4.4% of reviews being detected as Likely AI is just slightly higher than average false positive rates in AI detection.

Note: False positive rates can vary by AI detection model and company.

Supplements Have The Most AI Reviews Across Health and Wellness Products

For our study, AI-generated reviews were segmented by product category:

  • Baby Formula
  • Skincare
  • Health Supplements

The aim of dividing the reviews was to evaluate how prevalent AI-generated reviews are across key consumer products in the health and wellness industry. 

Findings across product categories

While supplements had the highest amount of reviews that were Likely AI, skincare products exhibited a higher percentage of AI-generated reviews than baby formula. 

This suggests that AI tools are more commonly used in the review process for supplement and skincare products.

The baby formula category had the lowest percentage of Likely AI reviews, which is potentially due to the sensitive nature of the product and a correlating preference for human-generated reviews.

Key Insights

  • 6.66% of supplement reviews were Likely AI.
    • As a result, the supplement category had the highest AI presence across the health and wellness categories analyzed in this study.
  • 5.27% of skincare reviews were detected as Likely AI.
    • This reflects a wider use of AI content in less critical consumer goods.
  • 2.83% of baby formula reviews were identified as Likely AI.
    • This was the lowest percentage, highlighting consumer reliance on authentic human reviews in more sensitive health-related products.

The higher percentage of AI in supplement and skincare reviews may indicate a preference for AI content due to the abundance of similar product offerings where AI could be used to generate large volumes of reviews quickly.

Overall Across Several Industries AI Reviews Are Trending Upwards

Looking at the bigger picture, beyond AI reviews in sensitive consumer health and wellness goods, the presence of AI reviews is on average trending upwards across several industries. 

Since the launch of GPT-2, GPT-3, and GPT-4, AI reviews have steadily increased.

The rising trendline of AI reviews is depicted in the graph below.

A Comparative Look at AI Reviews Across Industries

To provide better context as to the presence of AI reviews across industries, let’s take a comparative look at how health and wellness product reviews stack up with the other studies we’ve conducted at Originality.ai.

Healthcare Clinic Reviews

  • 7% of U.S. hospital reviews are Likely AI
  • 13.1% of U.S. dental clinic reviews are Likely AI
  • 28.9% of U.S. plastic surgery clinic reviews are Likely AI
  • 12.1% of Canadian hospital reviews are Likely AI
  • 20.7% of Canadian dental clinic reviews are Likely AI
  • 17% of Canadian plastic surgery clinic reviews are Likely AI

The notable percentages of AI in healthcare clinic reviews across hospitals, dental clinics, and plastic surgery clinics in both the U.S. and Canada raise a number of ethical concerns. Read the full study on AI healthcare reviews here.

Holiday Shopping Reviews

  • 31.5% of holiday shopping reviews are Likely AI

We found that there is a notable seasonal increase in shopping reviews that were Likely AI over the holiday season. Read the full study on AI holiday shopping reviews here.

Airline Reviews

  • 10.7% of Air Canada reviews in 2024 are Likely AI
  •  7.1% of  American Airlines reviews in 2024 are Likely AI
  • 4.3% of British Airways reviews in 2024 are Likely AI

Some of the top airlines demonstrate high percentages of AI reviews, for comparative purposes, we are highlighting a few of the most popular airlines here. Read the full analysis of AI in airline reviews here.

Do Product Reviews Correlate to a High Star Rating?

Next, we investigated how AI-generated reviews impacted the average star ratings of products and their popularity (number of reviews). 

We compared AI-generated reviews to human-written reviews in terms of their influence on product ratings.

Key Insights

AI-generated reviews often had slightly higher star ratings compared to human-written reviews, but the difference was marginal.

How Do These Findings Impact Consumers?

Trust and Transparency

AI-generated reviews pose significant ethical concerns, especially in sensitive product categories like healthcare products

The lack of transparency around AI-generated content can mislead consumers, erode trust, and potentially manipulate consumer purchasing decisions.

  • Transparency: AI-generated reviews should be labelled clearly to ensure consumers know the content is generated by an AI and not a human.
  • Consumer Trust: The rise of AI-generated reviews can reduce consumer trust in product reviews, and numerous studies have shown that humans struggle to identify AI.

Potential for Manipulation

AI-generated reviews can potentially inflate product ratings, especially if used by companies to manipulate consumer perceptions, particularly for expensive and critical healthcare products. 

  • Supplements with higher AI review percentages may mislead consumers about the product’s efficacy.
  • Baby formula, a highly regulated category, requires transparency to avoid misleading parents seeking trustworthy information.

Final Thoughts

This report has highlighted the growing role of AI-generated reviews in health and wellness consumer goods

The analysis shows that while AI-generated reviews are prevalent, for the present, key health and wellness products are still primarily human-written across supplements, skin care, and baby formulas.

Although this study found that AI health and wellness product reviews fell within the range of false positives in AI detection, the presence of any AI-generated reviews for products like supplements or baby formula is a cause of concern both ethically and for establishing consumer trust in brands.

Methodology

This study analyzed supplement, skincare, and baby formula reviews for AI-generated content. 11,263 product reviews were collected across these industries. 

Reviews were classified based on the AI_Likelihood score, where reviews with a likelihood above 50% were categorized as AI-generated, and those below were considered human-generated.

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

What Are the Benefits of Using a Text Compare Tool?

Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.

What Files Can You Inspect with This Text Compare Tool?

We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.

Will My Data Be Shared?

There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
