Is Your Ad Copy Illegal? How to Check Advertising Claims for Food, Cosmetics and Medical Devices

"Take this supplement and your blood sugar stays steady." "This serum even removes acne scars." The person writing the copy only wants the product to sound appealing, but the same sentence can be fine marketing on one product and cross the line on another.

That is what makes advertising rules confusing. It is not just a question of whether a line is exaggerated. First look at what you are selling, then decide which set of rules applies. The same ad line is treated differently for food, cosmetics, medical devices and drugs.

This article covers what to check for six product categories, the most common misjudgments, and how to review your copy with AI before it is published.

First, identify the product category

How an ad may be written, which words to avoid and whether prior approval is needed all depend on the product category. Lawboss's ad compliance review covers six:

• General food
• Health food
• Cosmetics
• Medical devices
• Drugs
• Medical services (clinics and hospitals)

If the category is wrong, everything that follows is wrong too. So the first step in reviewing copy is always to confirm which category the product belongs to.

Four of the most common misjudgments

1. Picking the wrong product category

Some categories are not intuitive. Energy blankets, colored contact lenses and breathing-assistance devices are medical devices, not ordinary goods or drugs. Once the category is off, every judgment after it is off too.

2. Assuming a different word makes it safe

You cannot say "treat," but is "improve" or "regulate" fine? Not necessarily. What matters is the overall impression on the consumer. If it leads people to think the product can treat or prevent disease, changing the word may not help. Judge the whole sentence and the overall presentation, not just one word.

3. Assuming no promotional tone means it is not an ad

Merely listing indications, or placing content dressed up as an "interview" or "report," can still be treated as advertising. Whether something is an ad depends on its actual purpose, not on whether the text reads like a promotion.

4. Checking the copy but not who is publishing

Whether the content complies and whether the publisher is allowed to publish are two separate questions. For medical devices, drugs and medical services in particular, the publisher's own status is part of the check. However conservative the copy, a publisher who does not qualify still has a problem.

If a KOL or media outlet publishes the ad, does the responsibility move to them?

We would not assume so. The copy, talking points and approval process a brand gives to a KOL or media outlet should be checked in the first place. KOLs and media should also confirm the content is compliant. Risk goes down when both sides do their own checking.

After writing the copy: how to check it yourself

Work through these in order:

1. Confirm the product category. General food, health food, cosmetic, medical device, drug or medical service?
2. Confirm the approval or permit status. Is there a permit or number, and does it match the product named in the ad?
3. Check each sentence. Does it imply a cure, guarantee results, or contain false or exaggerated claims? Does it go beyond what is approved?
4. Confirm the publisher's qualifications. Does the publisher have the status required for this kind of product or service?
5. Confirm the format. Does it appear as a report, interview or testimonial while actually promoting?
6. Keep a review record. Save the reviewed version, the date and the reason for each edit, so you have something to refer to later.

Reviewing ad copy with AI in practice

Lawboss's ad compliance review turns the process above into a tool you can use directly:

1. Paste your ad copy. The system first identifies the product category, since each category has different rules.
2. Compare sentence by sentence. It checks whether the copy implies a cure, is exaggerated or false, or goes beyond what is approved.
3. See the flagged results. Clearly problematic phrases are marked, and items that need manual verification, such as ingredient content or qualifications, are noted separately.
4. Get a compliant rewrite. For problematic copy it can produce a rewritten version, with the original sentence, the rewritten text and the basis side by side.
5. Ask follow-up questions. Each result cites its basis, and you can keep asking about anything unclear.

One caveat: for things that require checking documents, such as ingredient content, whether a permit number is genuine, and the publisher's qualifications, the AI can only remind you to verify them. It cannot confirm them for you.

When you should still ask a lawyer

• The product is a medical device, drug or medical service, where regulation is relatively strict
• The ad budget is large and the reach is wide, so a takedown would be costly
• You have received an inquiry or notice from the authority
• The product category itself is disputed and you are unsure which one it belongs to

FAQ

Can I write "helps with" or "supports" in the copy?

It depends on the product category and what the whole sentence means. Different categories tolerate different wording, so judge by the whole sentence and the overall presentation, not a single word. You can paste the copy into the review tool and check it sentence by sentence.

Do posts on my own social media account count as ads?

If they promote a product or service to an unspecified audience, they can generally be treated as advertising, and being your own account does not exclude them.

Does the review cost anything?

A new account receives 50 AI conversation credits on activation, usable within 7 days, with no credit card required. You can try it on a real piece of ad copy first.

Closing

The point of advertising compliance is not memorizing every rule. It is forming a habit: after writing the copy, confirm the product category, check it sentence by sentence, and confirm the publisher's qualifications. Once that process is fixed, most of the risk gets caught before the ad runs.

To check the copy you have on hand, go to ad compliance review and paste it in to begin.
