Hipfullen uses PCL injections to add volume to flatter buttocks and gently lift the lower contour. The treatment is planned individually and involves no incisions. Collagen develops over time to restore fullness.
I look at more than volume. Balance between the two sides and the curve from the waist matter too.

with your own collagen
Hipfullen is our individualized buttock volume and lifting program, planned around position, contour, shape and skin texture. Your doctor assesses the pelvic structure and buttock shape, adds volume only where needed, and gently raises the lower buttock contour.
PCL, or polycaprolactone, is a medical material that supports the production of your own collagen as it gradually breaks down and is absorbed. The resulting support within the skin improves buttock volume, firmness and texture together.
Restores fullness to flatter buttocks. Small amounts of PCL are placed only where needed. The injection gives an immediate feeling of fullness, then collagen develops and the volume settles into place.
Refines the lower contour so the buttocks appear lifted. Collagen support develops around the lower border to hold the shape from beneath.
Improves balance in size and shape. Your doctor assesses the pelvic structure and buttock contours, then plans the injection sites and amounts separately for each side.
A higher buttock contour can make the legs appear longer and improve overall proportions. Volume is positioned to support and raise the lower contour.
Skin texture becomes smoother, even up close. Collagen produced as PCL gradually breaks down increases skin density from within.
Volume remains natural-looking over time. Your own collagen replaces the absorbed PCL, creating a structure that supports fullness.
Results depend on how treatment is planned and performed. We take time with every patient. A doctor handles your consultation and performs your treatment personally.

Dr. Chang-Hwan Cho was first author of a 2026 review in the Journal of Cosmetic Dermatology comparing the mechanisms of six collagen boosters, including PCL.
ZELTIQ recognized our clinic for Korea's highest CoolSculpting treatment volume in 2019. Hipfullen draws on that body contouring experience to plan buttock volume for each individual.
The curve at my sides looks smoother
The hollows at the sides of my hips looked uneven even in pants. When I was considering volume treatment, I cared more about a smooth, natural curve than making my buttocks much bigger. Afterward, the contours along my sides looked smoother and moving around was comfortable. I was happy with that.
My side contours flow more smoothly
My hips and buttocks looked flat, which made my figure feel very straight. At the consultation, we looked at the whole curve from my waist. After treatment, my side contours looked smoother than before. The difference in close-fitting clothes was what I liked most.
It feels more natural than I expected
I worried that adding buttock volume might look excessive. Once some of the swelling settled, the shape looked more natural than it had immediately afterward. To the touch, it felt less strange than I'd expected. I was happy with that, and I'm now watching how the shape holds up.
The outline under my clothes has changed
I like fitted clothes, but the hollows at the sides of my hips always bothered me. I wanted a natural amount of volume rather than a large change from the start, and the result was close to what I'd hoped for. More than the overall size, I liked how my side profile looked in clothes.
How does PCL restore buttock volume? An experienced doctor plans the injection sites and amount. PCL then develops volume in three stages.
The injected product gives an initial feeling of fullness and outlines the intended contours.
As PCL gradually breaks down in the body, your own collagen forms.
Collagen creates a structure that supports volume, giving a firmer silhouette.
Our approach
Your doctor first assesses pelvic structure, buttock shape, volume and skin condition, then selects the areas and injection amounts for a natural-looking result.

The hourglass figure is often described by a waist-to-hip ratio of about 0.7; studies of attractiveness frequently cite a range of 0.65–0.70.

Hipfullen focuses on gradually developing volume through collagen, rather than simply adding bulk. As PCL breaks down, it stimulates collagen to support the buttock contours planned for you.
Your doctor assesses pelvic structure and buttock shape, then uses Hipfullen to add volume only where needed. Refining and raising the lower buttock contour can make the legs appear longer and improve overall body proportions.
The injected product gives immediate fullness. As PCL breaks down, collagen develops over around 4–8 weeks, allowing the volume to become firmer and more natural-looking.
Yes. You can return to your usual routine immediately. For about 2 weeks, avoid pressure or massage on the buttocks and avoid saunas.
