Chest wrinkle filler put to the test — will it interfere with breast cancer screening?
NCT ID NCT04717934
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study tests a hyaluronic acid filler called GAL1906 to smooth wrinkles on the décolletage (upper chest). It also checks whether the filler affects how mammograms are read, which is important for breast cancer detection. Participants are women over 21 seeking treatment for chest wrinkles. The main study compares the filler to no treatment, and a sub-study looks at mammogram images from treated participants.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hyaluronic acid dermal filler gel
- What this could lead to
- If successful, this could offer a safe, non-surgical option for reducing wrinkles on the chest without affecting breast cancer screening.
- What could go wrong
- This is a small, early-stage study. Results may not apply to everyone, and there is a risk the filler could interfere with mammogram interpretation.
