Can a cream with good bacteria fix sensitive skin?
NCT ID NCT07454525
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test whether a facial cream containing postbiotics (beneficial bacteria byproducts) can improve the skin microbiome and appearance in 45 women aged 40-60 with sensitive skin. Participants will use a placebo cream for 6 weeks, then the active cream for 8 weeks. Researchers will track changes in skin bacteria and take photos to see if skin looks healthier.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Facial cream with postbiotics from Bifidobacterium and Pediococcus
- What this could lead to
- If it works, this could point toward a skincare product that improves skin health and appearance by supporting the skin microbiome.
- What could go wrong
- This is a small, early-stage study with only 45 participants and no blinding. It measures microbiome changes, not clinical outcomes, so results may not translate to real-world benefits.
