BioStackr helps premium skincare brands measure what real customers experienced over 30 days, then turns those findings into a public proof page, private brand report, and claim-ready marketing direction.
Each BioStackr skincare cohort follows your customers daily for 30 days, with every result measured against their own pre-product baseline. Findings are framed as customer-reported outcomes, not clinical claims, so your team has a defensible basis for every claim that lands in market.
Illustrative of the kind of outcomes a BioStackr skincare cohort produces. Real cohort findings are calculated against each participant's own pre-product baseline, across approximately 30 days of daily check-ins per participant, with confound days (sun exposure, hormonal flare, new products, stress, heavy makeup) filtered from the primary analysis.
A hosted, beautifully presented results page showing the headline findings, the methodology, and what your customers noticed in their own words. Use it anywhere a buyer needs to see proof.
The deeper read for your marketing, product, and compliance teams: what your customers had tried before, what almost stopped them buying again, the words they used when they saw results, and which claims will land hardest in market.
The proof page shows the market your product works. The report shows your team why, and what to do with it.
The headline result tells you whether your product worked. The commercial layer tells you how to sell that proof: what skin concerns your customers tried to solve before, what almost stopped them buying again, what proof formats they trust, and the exact language they use when their skin improves.
BioStackr translates cohort findings into clear claim language your marketing and compliance teams can review, sized for the channels skincare brands actually use.
Final wording always goes through your own compliance review. We frame findings as customer-reported outcomes, never as clinical or treatment claims.
Your team does not run the study. We handle the setup, screening, customer flow, daily tracking, reminders, analysis, and reporting. You approve the design, invite your customers, ship the product, and review the output.
You invite your customers. We provide the study page and the application flow.
Customers apply. We screen for the right skin concern, routine stability, and outcome fit for your product.
Participants complete pre-product check-ins so every result is measured against their own starting point.
Customers track daily skin outcomes matched to your product claims, with confound tagging for sun, makeup, hormonal flare, stress, sleep, and any other product changes.
We run the statistical analysis using Cohen's d, bootstrap confidence intervals, and baseline-adjusted effect sizes, then code the customer voice layer.
You receive the public proof page, the private report, and the full marketing kit.
Skincare cohorts work beautifully when customers can notice a meaningful difference within 30 days, with routines stable enough to measure cleanly.
If your customers can see or feel it within 30 days, BioStackr can usually measure it.
Findings are framed as customer-reported outcomes from a real-world study, never as clinical or treatment claims. That gives your compliance team a defensible basis for every claim that goes to market, and keeps your brand clear of the FTC scrutiny that has hit hundreds of skincare brands in recent years.
Brands retain full editorial control. Every claim still passes through your own compliance review for each market. We make that review faster, not heavier.
BioStackr skincare studies are premium real-customer evidence projects, not basic product sampling.
Pricing depends on the product, cohort size, study design and reporting depth. Request a study overview and we'll show you the recommended structure for your brand.
We also run a small number of reduced-rate partner studies for brands that are a strong fit for a public BioStackr case study. If your product is a fit, we'll include that option in the overview.
Tell us the product and the outcome you care about. We will show you what a BioStackr cohort could measure for your brand, and what kind of evidence it could create.
