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.
