Hip dips, also called violin hips, are the inward curve that appears between the hip and the thigh. They depend mainly on the shape of the pelvis and femur, and on how fat and muscle are distributed. They are a normal variation of the body. If they bother you, they can now be softened without surgery, using a collagen stimulator approved by INVIMA (Colombia's national health products regulator) for body use.
At the El Poblado office, Dr. Olga Gómez Montoya, physician and surgeon trained at the University of Antioquia, first assesses whether you are a candidate and what can be achieved in your case. The goal is a hip line that is more in harmony with your body, not a shape that isn't yours.

Hip dips are an inward curve on each side of the body, between the hip bone and the upper thigh. They are also known as violin hips, because of the shape they draw in the silhouette.
They are not a health problem or a sign of being overweight. They appear in slim women, in athletes and in bodies of every size.

It's not the right time if…
They appear mainly because of each person's anatomy. Three factors determine how noticeable they are, which is why two women of the same weight can have very different hips.
The width of the pelvis, the height of the hip and the angle at which the femur joins it. This is the most influential factor, and it doesn't change with creams or diets.
Especially the gluteus medius, which sits on the outer side of the hip. Exercise strengthens it and can partly improve the contour.
How fat is distributed in the area and how firm the skin is. Over the years collagen decreases, and the transition can become more noticeable.
With a collagen stimulator placed in the area of the curve. The product prompts your skin to produce its own collagen and, over the following weeks, softens the transition between the hip and the thigh. No volume foreign to your body is added: it's your own tissue that responds.
Esencial hip dip biostimulation is Dr. Olga Gómez Montoya's plan, in El Poblado, Medellín, to soften the curve between the hip and the thigh with a collagen stimulator that is INVIMA-approved for body use. One or two sessions of 45 to 90 minutes are done, under local anesthesia.
Partly. Exercise strengthens the gluteus medius and can improve the hip contour, and it always helps. What it doesn't do is change the shape of the bone. Ideally, the two are combined: the result looks better over a well-trained muscle.
Hip dips are treated on the outer side of the hip. If what you're looking for is firmness or contour in the buttocks, the treatment is non-surgical buttock contouring, with the Armonía, Contorno and Contorno Integral plans. Both areas are reviewed during your assessment.
Because hip dips depend largely on your bone structure, we explain clearly what is possible before you begin.
“In August I said I didn't offer it, and that was true. Changing your position when the facts change is also medical judgment. What doesn't change is that I assess you first.” — Dr. Olga Gómez Montoya, physician and surgeon, University of Antioquia
It is a minimally invasive procedure, using a product that is INVIMA-approved for body use. Like any medical procedure it carries risks, and these are explained before you decide:
That's why the assessment, the technique and the follow-up visits matter. At this practice we never use biopolymers or peptones, or any product without INVIMA health registration.
Why didn't we offer it before, and why do we now?
In August 2026, Dr. Olga explained publicly why she did not offer body biostimulation: she did not have a product with INVIMA approval for that use. Today that product exists, and its registration was verified before it was added. The rule hasn't changed: we only offer what we can stand behind.
Dr. Gómez reviews the anatomy of your hips, the quality of your skin and your expectations. She determines whether you're a candidate and how many sessions you need.
In the office, with local anesthesia in the area. It takes 45 to 90 minutes.
You may notice some volume the same day: that's the fluid used in the application, and it is reabsorbed within a few days. You'll receive written aftercare instructions.
The real change begins between 2 and 3 months, because it's your own collagen doing the work. If two sessions are needed, they are spaced 45 to 60 days apart. The result is evaluated at 3–4 months.

Partly. Exercise strengthens the gluteus medius and can improve the contour, but it doesn't change the shape of the bone. When the curve is mainly structural, a medical treatment can complement your training.
With a collagen stimulator that is INVIMA-approved for body use, placed in the area of the curve. It stimulates your own collagen production and gradually softens the transition. An assessment is done first to determine whether you're a candidate.
It is a medical treatment that uses a collagen stimulator to soften the curve between the hip and the thigh. At Dr. Olga Gómez Montoya's office in El Poblado, Medellín, it is offered as the Esencial plan, with one or two sessions depending on your assessment.
The volume you notice on the day is the fluid used in the application, and it is reabsorbed within a few days. The real change begins between 2 and 3 months, because it's your own collagen doing the work. A follow-up visit is done at 3 or 4 months.
One or two sessions, depending on your anatomy and the quality of your skin. If two are needed, they are spaced 45 to 60 days apart. Each session takes 45 to 90 minutes and is done with local anesthesia in the area.
Because the result comes from your own collagen, it doesn't disappear overnight. How long it lasts varies with each person's age, metabolism, weight and habits. During your assessment we'll explain what to expect in your case and when a follow-up visit is advisable.
It is minimally invasive and done with a product that is INVIMA-approved for body use. It can cause temporary swelling, bruising or tenderness and, less often, nodules or asymmetries. Biopolymers and peptones are never used.
It depends on your anatomy, the amount of product and the number of sessions. At your consultation in El Poblado, we'll clearly explain your plan and its investment.
If your hip dips bother you, the first step is understanding your case. Dr. Olga will tell you whether you're a candidate and what can and can't be achieved. If the treatment isn't right for you, she'll tell you that too.
