WHAT WAS TESTED

To evaluate the effect of ZINDEO Anti-Odorant Cream on the underarm skin microbiome following 28 days of daily application.

Primary endpoints:

• Change in microbial diversity (Shannon Diversity Index)
  
• Presence of pathogenic bacteria
  
• Relative abundance of odor-associated bacterial strains

Skin swabs from 10 human subjects (underarm area) were collected at baseline (Day 0) and after 28 days of use.

Bacterial identification performed using standardized rapid biochemical testing methods.

Results reflect laboratory-evaluated study conditions.

Microbial diversity evaluated via Shannon Diversity Index.

Testing conducted January–February 2026.

90% — of subjects (9 out of 10) showed increased skin microbiome diversity after 28 days of daily use.

70% — of subjects showed a reduction in total bacterial count while microbiome diversity increased.

28 days — independent human testing conducted under EU cosmetic regulations.

WHO TESTED IT:
J.S. Hamilton Poland — accredited laboratory, Gdynia, Poland.
Testing conducted under EU Cosmetic Regulation (EC No 1223/2009) and Cosmetics Europe guidelines.

Under laboratory-evaluated study conditions, 28 days of daily application of ZINDEO Anti-Odorant Cream demonstrated:

• Increased skin microbiome diversity in 90% of subjects (9/10)
• Reduction in odor-associated bacterial strains (Corynebacterium, S. epidermidis)
• Reduction in total bacterial count in 70% of subjects while microbiome diversity increased
• Preservation of all resident skin bacteria — no natural strain was eliminated

Increased microbial diversity is widely associated with improved ecosystem stability and resilience. Fewer bacteria with better distribution indicates optimization, not disinfection.

These findings support ZINDEO's positioning as a microbiome-tested anti-odorant designed to work in harmony with the skin's natural microbial balance.

WHAT WAS TESTED

To evaluate whether ZINDEO controls underarm body odor for up to 72 hours after application.

Split-body design: one underarm used ZINDEO, the other served as an untreated control. Odor was assessed at 24, 48 and 72 hours by trained assessors under blind conditions, without knowing which side was treated.

Each subject served as their own control, removing differences between individuals — the only variable was the product.

Testing conducted 2026.

72 hours — the treated underarm stayed significantly fresher than the untreated control, three days after application.

Significant at every interval — odor reduction held at 24h, 48h and 72h.

p = 0.0109 at 72h — the result was strong enough to rule out chance (p < 0.05).

WHO TESTED IT:

J.S. Hamilton Poland — accredited laboratory, Gdynia, Poland.

Report No. 968271-1/25/GDA/PK (2026).

Conducted under EU Cosmetic Regulation (EC No 1223/2009) and Cosmetics Europe guidelines.

Under laboratory-evaluated study conditions, ZINDEO Anti-Odorant demonstrated:

Significant odor reduction vs. untreated control at 24h, 48h and 72h

Effect maintained three full days after a single application

Odor control achieved without blocking sweat — by keeping odor-causing bacteria in check, not by masking

These findings support ZINDEO's positioning as an anti-odorant clinically tested for 72-hour odor control.
