Case study · Health & Wellbeing
Molarclean sells teeth whitening in a market full of cheap rivals, on a modest budget. Its social was mostly Facebook, Instagram was patchy and TikTok untouched. Over seven months we rebuilt its content around real people, launched TikTok and moved into TikTok Shop and conversion ads. In the first month of conversion activity it returned £1.34 for every £1 spent.

What did Molarclean need?
Molarclean had to sell teeth whitening against cheap competitors, with a modest budget. Its community had gone flat.
- Business objective: turn social into a sales channel.
- Communication objective: grow and re-engage the community across TikTok, Instagram and Facebook, then convert it.
What was the insight?
People trust other people’s smiles more than product shots. User-generated content feels honest in a category full of claims.
The idea was people-led content, then conversion.
What did we do?
- People-led UGC. We rebuilt organic content around real people using the product.
- TikTok from scratch. We launched and scaled TikTok.
- Always-on paid social. Paid activity ran against clear objectives.
- Into sales. We moved into TikTok Shop and Meta conversion ads.

What did we learn?

- Real people sell. UGC outperformed polished product content.
- What we would do differently. set up full-funnel tracking from the start, so we can show sales from organic as well as paid activity.
