What You Can & Can't Say
The Golden Rule of Claims
Learn how to write cosmetic appearance claims that sound vivid, stay precise, and keep the product promise inside the evidence it earned.
card 01
You have amazing true things to say. This is how you say them.

for the marketer
Start with the result a client wants to see. Then write one precise line that earns her trust.
for the professional
Draft in this order:
- DESIRE
- name the look, feel, or performance she wants
- RESULT
- choose a visible or sensory outcome
- SCOPE
- attach the exact product and qualification
- PROOF
- add only the evidence that belongs to that claim
This sequence keeps the benefit in front and the support close behind.
for the skintellectual
This lesson is the writing bench: choosing verbs, building sentences, and editing the total claim. The science-communication foundation lives in [Cosmetic vs Drug Claims in Beauty](/learn/ingredients-clinicals/how-we-talk-about-our-science), including intended use and the distinction among ingredient, finished-product, and regimen evidence.
Here, turn that foundation into copy a distributor can say naturally: visible result first, exact scope second, substantiation ready when the statement needs it.

The safe-structure formula: [visual verb] + "appearance of" + [cosmetic noun]
![The safe-structure formula: [visual verb] + "appearance of" + [cosmetic noun]](/learning-hub/assets/img/photography/card_resilience.jpg)
for the marketer
Use visibly smooths the look of fine lines: a strong verb, a visible result, and no promise to change the body.
for the professional
Build the sentence from three parts:
- VERB
- visibly smooths, helps soften, supports, enhances
- FRAME
- the look of, the appearance of, visibly
- NOUN
- lines, texture, radiance, fullness, firmness
The frame should sound natural, not pasted on. "Leaves skin looking smoother" can be just as precise as "improves the appearance of texture."
for the skintellectual
Grammar carries the scope. A visual verb tells the reader what can be observed. The appearance frame limits the statement to a cosmetic result. The noun names the exact feature being judged.
Qualifiers belong beside the word they limit: "helps reduce the appearance of fine lines over time" does not become "reduces fine lines" in a headline. Preserve the qualifying words wherever the claim travels.
card 03
The red-flag words: test the verb and its object

for the marketer
Read the action and its target together. Smooths texture is cosmetic; rebuilds tissue promises biological change.
for the professional
Circle the verb, then underline its object.
- REFINE
- stimulates collagen → supports firmer-looking skin
- REFINE
- regenerates cells → helps skin look renewed
- REFINE
- treats acne → helps skin look clearer
The risky pattern is not drama alone. It is a product promising to change tissue, a body process, or a condition.
for the skintellectual
A claim is read as a complete thought. "Supports" can still overreach when its object is a disease or an unproven biological process; "improves" can be appropriate when its object is a documented appearance endpoint.
Check subject, verb, object, and context together. Disease names paired with diagnosis, prevention, mitigation, or treatment stay outside cosmetic selling. Translate the desired benefit into what the client can see or feel without implying medical care.
card 04
"Penetrates" needs an object and a boundary
for the marketer
Name the cosmetic boundary: absorbs quickly, spreads evenly, works across the outer surface. Depth is not the benefit.
for the professional
Delivery language becomes risky when it promises biological action at an unearned depth. Replace "penetrates deep to repair" with the result the client wants: "absorbs quickly and leaves skin feeling smooth."
If surface delivery matters, name the boundary accurately. Ingredient research may describe its own laboratory method; finished-product copy still needs evidence for the complete formula.
for the skintellectual
Depth, mechanism, and finished-product performance are separate claims. A supplier may study how a named ingredient behaves under a defined method. That does not prove that every finished formula reaches the same location or produces the same biological action in living skin.
Write the customer claim at the level earned by the finished product: surface application, absorption, feel, spread, or visible outcome. Keep ingredient science attributed to the ingredient and method.
card 05
Numbers are welcome when the complete claim travels

for the marketer
A strong result keeps the tested product, endpoint, timing, qualifier, and source together.
for the professional
Before publishing a result, check five fields:
Never lend a neighboring formula's result, round the value, or turn one participant's experience into a study conclusion. Practice the edits in [Say This, Not That](/learn/legal-claims/say-this-not-that).
for the skintellectual
FTC substantiation follows the objective meaning a reasonable reader takes from the whole claim. The support must exist before publication and match that meaning.
A short customer sentence can remain elegant when its scope is complete and the deeper method sits at the evidence destination. Keep article, endpoint, timing, and qualification in the sentence; keep method, sample, comparator, and source available without turning them into sales decoration.
