ZINDEO CLINICAL TESTING: SKIN MICROBIOME AND BODY ODOUR

STUDY 1

ZINDEO AND THE SKIN MICROBIOME

What changed after 28 days of daily Anti-odorant Cream use?

• 10 participants
• underarm swab on day 0 and after 28 days
• daily application of ZINDEO Anti-odorant Cream
• microbial diversity, pathogenic bacteria, and odour-associated bacteria monitored
• diversity assessed using the Shannon index

testing conducted January–February 2026 

9 out of 10 participants showed higher microbiome diversity

After 28 days of daily use, 9 out of 10 participants had higher skin microbiome diversity. In 70% of participants, the total bacterial count also decreased while diversity increased.

Odour-associated bacterial strains, including Corynebacterium and S. epidermidis, decreased.

No naturally resident bacterial strain was eliminated.

Higher microbial diversity is generally associated with greater ecosystem stability and resilience. A lower bacterial count combined with better distribution suggests optimisation rather than disinfection.

The results reflect the conditions of the laboratory-evaluated study. Bacterial identification was performed using standardised rapid biochemical testing methods.

STUDY 2

BODY ODOUR CONTROL AFTER A SINGLE APPLICATION

Treated and untreated underarms were compared over 24, 48, and 72 hours.

• split-body design: one underarm was treated with ZINDEO
• the other remained untreated as the control
• each participant served as their own control — the product was the only variable
• odour was assessed blindly by trained evaluators who did not know which side had been treated
• assessments after 24 h, 48 h, and 72 h
• testing conducted in 2026

32% lower body odour intensity after 24 hours

After 24 hours, body odour intensity in the treated underarm was 32% lower than in the untreated underarm.

The difference remained statistically significant after both 48 and 72 hours. At 72 hours, the difference was statistically significant at p = 0.0109.
