As the years go by, it's natural for the buttocks to lose firmness, volume or symmetry — whether due to genetic factors, aging, or after weight loss. The Bumbum UP® method, developed by Dra. Chris Marchetti, combines hyaluronic acid filler, collagen biostimulators and complementary techniques to reshape, add volume and harmonize the buttock area, with same-day results, no surgery and no complicated post-surgical recovery.

The protocol is recommended for those who want to increase buttock volume, correct asymmetries, fill in depressions (including the so-called trochanteric depression, on the "lateral hip"), treat cellulite and improve signs of sagging skin, restoring contour, support and a "lifted booty" effect with a natural result.

The technique combines different complementary approaches: hyaluronic acid filler, which provides immediate volume and contour; collagen biostimulators, which work progressively, stimulating the body to produce new collagen over 60 to 120 days, promoting firmness and a natural look; and subcision, a technique indicated for treating cellulite, which releases the fibrous bands responsible for skin depressions, improving their appearance and evenness. In addition, the method can include other complementary techniques within an exclusive, personalized protocol, defined according to each patient's individual needs and characteristics.

The procedure is minimally invasive, performed in-office under local anesthesia, and allows a return to normal activities the same day. Generally, 1 to 3 sessions are needed, spaced 30 to 60 days apart, depending on the goal and Dra. Chris's personalized consultation for each patient. Visible results appear right after the first session, and the full effect of the biostimulators is established from 8 weeks onward.

Bumbum UP® is not recommended for pregnant or breastfeeding women, people with active infections in the area, uncontrolled autoimmune conditions, or allergies to any of the components used — which is why every patient undergoes a personalized consultation before the procedure, ensuring safety and the most suitable plan for their body type.
