Your Own Biology, Elevated

At Grossman Dermatology, Dr. Karyn Grossman, MD, has spent decades mastering the art of natural-looking rejuvenation. As a board-certified cosmetic dermatologist with a fellowship at Harvard University and over 138,000 patients treated, Dr. Grossman is uniquely positioned to combine innovative fat transfer techniques with her unparalleled arsenal of advanced technologies. Her philosophy has always centered on results that look genuinely refreshed, never overdone. Fat-based injectables align perfectly with that vision, using your own tissue to restore, regenerate, and renew.

What Are Fat Transfer, Micro Fat & Nano Fat Injections?

Fat transfer, also called lipotransfer or fat grafting, is a procedure in which fat is harvested from one area of your body and strategically injected into the face or other areas to restore volume or improve skin quality. There are three distinct types used in cosmetic dermatology: macrofat for larger volume areas, microfat for precise structural support in delicate zones, and nanofat for regenerative skin rejuvenation at the intradermal level.

Here's how each differs:

Macrofat restores significant volume loss in broader areas using larger fat particles.
Microfat uses smaller particles harvested with a fine cannula, ideal for the forehead, eyelids, brows, nose, and hands, where injecting larger particles would risk complications.
Nano Fat consists of a regenerative matrix rich in adipose-derived stem cells. Its primary benefit is regeneration, not volumization, making it ideal for improving skin texture, stimulating collagen production, and enhancing overall skin quality.

Microfat and nano fat are typically performed together: microfat provides soft tissue structural support and a filling effect, while nanofat enhances skin quality and promotes tissue regeneration.
