How Far Can Influencer Posts Go When Promoting Beauty Brand Ingredients and Effects?

There is a certain range within which facts about beauty brand ingredients and effects may be communicated, but even in influencer posts, definitive claims of effect—such as "my skin quality changed after using this"—need to be avoided. Simply adding the phrase "this is a personal opinion" does not resolve the underlying issue with the definitive claim itself. Keeping expressions within the range of usage impressions is the practical standard to follow.

How Far Can Ingredient and Effect Claims Go?

Expressions that fall within the range of effects officially recognized for cosmetics—such as providing moisture or conditioning the skin—can be shared in influencer posts. However, once the language crosses into definitive claims, such as stating that a specific symptom will improve or that results are guaranteed, it falls outside what is permitted as cosmetics advertising.

Is It Fine as Long as "This Is a Personal Opinion" Is Added?

No, it is not. Even if the content is framed as a personal experience, if the post as a whole leaves the impression that "effects are guaranteed," it becomes subject to advertising regulations regardless of the impression-based framing. It's important to understand that the phrase "this is a personal opinion" does not cancel out the problem posed by the definitive claim itself.

How Should This Be Communicated When Making a Request?

A practical approach is to phrase the request as: "Rather than making statements that guarantee changes to the skin, please describe your impressions or preferences after trying the product." Sharing a few concrete examples of preferred phrasing in advance allows the influencer to post with confidence.

What Should Be Done When It's Unclear How to Judge?

If there is any uncertainty about whether a draft post contains a definitive claim, it should be reviewed before publication, with adjustments to the wording requested if necessary. When in doubt, the general rule is to lean toward more modest phrasing.

In Closing

Ingredient and effect claims should be communicated within the range of usage impressions, avoiding definitive statements. Rather than relying on the framing of a "personal opinion," the practical standard is to refine the expression itself.
