The Challenge
RoC set out to launch their Hydration+ Plumping Serum Stick, a dermatologist-developed innovation designed to smooth fine lines, rejuvenate mature skin, and deeply hydrate.
The team wanted to put their latest breakthrough into the hands of real customers before launch - checking efficacy, ranking benefits, and uncovering purchase likelihood among their target demographic of women aged 45+.
The Process
1
Using Sourcerie, RoC recruited a dedicated community of 1,000 top US customers to tap into as product testers.
2
From this community, 100 participants aged 45+ were selected, all with specific skin goals around anti-aging and hydration.
3
Over a two-week period, testers trialed the Hydration+ Serum Stick at home, with targeting and opt-ins, product send-outs, instructions for protocol, and communications all managed through the Sourcerie platform.
4
Through a mix of quantitative and qualitative research, RoC gathered insights on:
Efficacy and key benefit ranking
Purchase likelihood and switching data (from existing routines/products)
Net Promoter Score (NPS)
In-depth qualitative feedback on experience and results
The Result
Customer validation to support dermatologist-led innovation
Clear rankings of the most resonant benefits, helping RoC focus on the claims and messaging that matter most.
Insights on purchase likelihood and switching behaviour, enabling the team to size the opportunity and forecast uptake more accurately.
A strong NPS and positive qualitative feedback, showing the product was delivering on its dermatologist-developed promise.
All of this insight was delivered in just two weeks - ensuring the Hydration+ Serum Stick launched with confidence.
