Sampling for beauty and personal care
Nobody believes a before and after in a brand ad. They believe the friend who used it for a fortnight and said what actually happened to their skin.
Why this category runs on somebody else's face
Beauty and personal care is the most content-hungry category in retail and the least tolerant of content that looks staged. Shoppers have been looking at retouched skin their whole lives, and they discount it automatically. What they do not discount is a person with their own bathroom lighting saying what a product did over two weeks.
The category also has a compliance line running straight through the middle of it. A moisturiser is a cosmetic. A moisturiser that treated somebody's eczema is a therapeutic claim, and that changes what a person is allowed to say in a post no matter how sincerely they mean it.
theSalt runs the category as a purchase-first programme. Customers buy the product where it is ranged, use it for as long as the brief needs, and post the result, with content moderated before anything is licensed or amplified.
Trial that lasts longer than a sample sachet.
Skin, hair and fragrance are judged over days. The brief is written for that.

The line between cosmetic and therapeutic.
A cosmetic claim describes how a product looks, feels or smells. A therapeutic claim says it treated, prevented or cured something. New Zealand's therapeutic and health advertising code, in force from 1 July 2026, is clear that a person cannot make a therapeutic claim about a product in an advertisement, and content a brand has paid for is an advertisement.
Written properly, the brief keeps the category open, because a customer who is told clearly what the product is for tends to talk about it accurately.
- No therapeutic testimonials. A customer may not say a cream treated their eczema or a supplement fixed their sleep, however true it felt to them.
- Cosmetic language is fine. How it feels, how it applies, how it smells, what their skin looked like: all of that is fair.
- Moderation happens before licensing. Content that crosses the line is rejected rather than edited into something the customer did not say.
- The advertising label still applies. Ad, Advert or Advertisement at first interaction on every paid post.

What beauty brands ask us.
Can customers show a before and after?
They can show what their skin or hair looked like, which is a cosmetic observation. What they cannot do is present it as treatment of a condition, because that is a therapeutic claim and it is not permitted in an advertisement.
How long should a beauty trial run?
Long enough for the product to have done something. A fortnight is a common window for skincare, and the brief sets it before anyone is recruited.
Does this work for premium or prestige products?
Yes, and the purchase step matters more there, not less. A customer who spent their own money on a NZ$90 serum is a far more persuasive voice than one who was couriered a free one.
Can we specify the retailer?
Yes. If a Chemist Warehouse or Farmers result is the point of the campaign, recruitment filters for shoppers of that retailer.
