Hip dips, can they be

filled with exercise?

Don't believe that claim

Hello,

Q. Don't hip dips go away if you do a lot of squats?

A. Hip dips aren't caused by a lack of muscle—

they come from the structure of the pelvic bones.

Exercise alone can't fill them in.

Q. Is hip dip filler a procedure that makes the butt bigger?

A. No, it isn't.

It fills the hollow space beside the pelvis,

making the leg line look longer and more natural.

💡 Dr. Wi Young-jin's key insight

Hip dips—the hollow space beside the pelvis—

are hard to fill even with exercise,

but filling them in can make your legs look longer.

Let me walk you through it.

Why do hip dips happen?

The real reason exercise doesn't work

Stand in front of a mirror and look at the side of your pelvis—

do you see a slight hollow just above where

the thigh begins?

That's a hip dip.

A lot of people assume, "I guess I just don't work out enough,"

but honestly, that's a misunderstanding.

Hip dips aren't a matter of muscle mass or body fat—

they happen because of the position of the greater trochanter,

a part of the pelvic bone.

The greater trochanter is the bony bump that protrudes

on the upper outer side of the thigh.

The more this bone juts outward,

the deeper the hollow space

that forms above it on the side of the pelvis.

No matter how developed your muscles are,

you simply can't fill in the concave area above that bone structure.

Here's where it gets tricky: sometimes, the harder you work out,

the more pronounced the hip dips actually look.

When the glute muscles develop,

the volume below them goes up,

but the hollow stays the same—so the contrast becomes more obvious.

Now, here's one important point.

Why do hip dips make your legs look shorter?

The side line running from the waist to the thigh

needs to flow smoothly

so the eye travels naturally from top to bottom—

that's what makes legs look long.

But when the side of the pelvis is hollowed out, that line breaks,

creating a 'disconnect' between waist – hip dip – thigh.

The moment that disconnect appears, the eye stops there,

and your legs are perceived as shorter than they actually are.

On the other hand, if you gently fill that hollow with filler,

the line reconnects,

and the eye flows downward without interruption.

The 'longer legs' effect doesn't come from being taller—

it comes from the continuity of that line.

👨‍⚕️ Dr. Wi Young-jin's key takeaway

Hip dips are a structural issue of the pelvic bones,

so they can't be filled in with exercise.

When this hollow space is filled with filler,

the side line from waist to thigh becomes smoother,

and the moment that line becomes continuous,

a visual effect kicks in that makes your legs look longer than they really are.

It's not about 'adding' volume—

it's about creating 'continuity' in the line.

Hip dip filler—

how you approach it

determines the result

Each case is different,

but here's how I usually approach it.

First, with the patient standing,

I look at the entire pelvic line.

When you check while sitting,

the depth and position of the hollow shift.

I also check the depth and width of the hip dip,

and whether its position is symmetrical on both sides.

More people than you'd expect have asymmetry between left and right.

Next, I decide on the type of filler.

For filling a relatively wide and deep area like a hip dip,

a high-G-prime filler is the standard choice.

G-prime refers to the filler's elasticity—

simply put, its 'ability to hold its shape.'

If this value is too low,

the filler can spread or sag over time.

Here's a common misconception:

more filler is not always better.

It's important to find the minimum volume that creates natural-looking volume,

while accounting for the thickness and elasticity of the tissue around the hip dip.

Overfilling can actually make the area

bulge out unnaturally.

Compared to other filler procedures, hip dip filler tends to require a larger volume,

so the cost can be higher,

and for about 2–4 weeks after injection,

you'll need to avoid postures that put pressure on the area

or tight bottoms.

Duration varies from person to person,

but it usually lasts about 1 to 1.5 years.

That said, for those who've struggled with hip dips that exercise couldn't fix,

or who've felt self-conscious because their leg line looked broken,

it's an option that delivers noticeable results.

At our clinic, many patients who came in saying,

"I was told elsewhere that exercise wouldn't work,"

have walked away satisfied after 2–3 sessions.

Frequently asked questions

Q1. After hip dip filler,

does sitting feel strange?

A. For about a week after the injection,

you may feel a bit of soreness.

If pressure is placed on the area while sitting for long periods,

it can feel uncomfortable,

but this naturally fades as the filler settles.

After 2 weeks, most people can resume daily life

without any discomfort.

Q2. Is one session of hip dip filler enough,

or do you need multiple?

A. It depends on the depth of the hollow.

For some, a single session is enough

to smooth out the line.

But if the hollow is deep or there's significant left-right asymmetry,

splitting it into two sessions

tends to give a more natural result.

It's more accurate to assess in person during a consultation,

so rather than deciding based on online info alone,

come in with an open mind.

Q3. Can hip dips be filled with fat grafting

instead of filler?

A. Yes, they can.

However, fat grafting comes with variability in graft survival,

and it requires surgical recovery.

For filling a relatively localized space like a hip dip,

high-G-prime filler tends to give more predictable results,

so I usually suggest filler first.

Of course, if you have enough fat

and want a more overall change in your body line,

there are cases where fat grafting is the better fit.

Don't give up on hip dips just because exercise doesn't work.

I recommend a thorough consultation before the procedure

before making your decision.
