Mushroom magic? shiitake extract cream shows promise for oily, Acne-Prone skin
NCT ID NCT06338046
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a cream made from shiitake mushroom extract (SMosE) to see if it could improve skin barrier function, reduce oiliness, and soothe acne-prone skin. Researchers studied the extract in the lab and on human skin samples, then tested the cream on 40 adults with acne-prone or scarred skin. The trial was double-blind and placebo-controlled, meaning neither the participants nor the researchers knew who got the real cream.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Shiitake mushroom oil-soluble extract (SMosE) in a topical cream
- What this could lead to
- If it works, this could point toward a natural ingredient for managing oily, acne-prone skin and improving skin hydration.
- What could go wrong
- This is a small, completed early-stage trial with only 40 participants. Results may not apply to everyone, and the extract is tested as a cosmetic, not a medicine.
