What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if Radiesse, a treatment for reducing chest wrinkles, affects breast tissue appearance in medical imaging tests such as mammograms and ultrasounds. Participants will receive three Radiesse injections over several weeks. Individuals with moderate to severe chest wrinkles who are willing to undergo multiple imaging tests may be suitable for this trial. Participants should not have any serious breast conditions or a history of breast cancer. As an unphased trial, this study provides a unique opportunity to contribute to understanding the cosmetic and medical imaging effects of Radiesse.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that Radiesse is safe for use in the décolleté area?

Research has shown that Radiesse, a type of skin filler, is generally safe when used correctly. Used for nearly 20 years, it is approved in some countries, such as Canada, for reducing wrinkles in the chest area, indicating its likely safety.

However, some reports of side effects exist. Between 2018 and 2025, the manufacturer received 44 reports of possible side effects, including serious issues in the chest area. Despite this, experts like dermatologists and plastic surgeons reviewed Radiesse in 2019 and confirmed its general safety when used properly.

Overall, while some risks exist, most people tolerate Radiesse well. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard of care for chest area rejuvenation, which often involves topical creams or laser treatments, Radiesse is unique because it is an injectable filler that provides immediate volume and stimulates natural collagen production over time. This dual action not only smoothens the skin but also promotes long-term improvement in skin texture and firmness. Researchers are excited about Radiesse because it offers both instant results and sustained benefits, potentially reducing the need for frequent maintenance treatments.

What evidence suggests that Radiesse is effective for chest area imaging?

Research has shown that Radiesse effectively thickens and firms skin while reducing wrinkles. It improves skin in 95% of people aged 30–40, 80% of those aged 40–60, and 70% of those over 60. Radiesse acts as a regenerative biostimulator, helping to rebuild skin components and resulting in healthier-looking skin. In this trial, participants will receive three injections of Radiesse in the décolleté area to study its effects on breast tissue imaging. Although this study focuses on Radiesse's potential impact on breast tissue imaging, strong evidence supports its benefits for skin improvement. ^{2 6 7 8 9}
