Estrogen Study

This study is being done to see whether applying a cream with estradiol (a form of estrogen) to the face can improve overall skin quality and help reduce fine lines and wrinkles in peri- and post-menopausal women, and how this relates to epigenetic changes in the skin. A part of the study will also include applying an extra rapamycin analog cream to the face, which is also believed to improve overall skin quality and help reduce fine lines and wrinkles.

WHY THIS MATTERS

Skin aging in peri- and post-menopausal women is deeply tied to hormonal shifts. This study explores whether topical estradiol can turn back the clock – cellularly.

Eligibility

You MAY qualify if you can answer YES to all:

I am a healthy female (peri or menopausal) between the ages of 40 and 65.

I have not had any cosmetic facial treatments in the last 1-3 months.

I have not had any GLP-1 treatments in the last 6 months.

Study Design and Duration

The study includes daily evening application of study cream for 12 weeks, followed by 4 weeks with no test product use. In total, the study will last 16 weeks or approximately 4 months.
