01HYAcorp injections: shaping your buttocks without surgery
There are two main ways to enhance the buttocks: the surgical route — buttock implants or buttock lipofilling (Brazilian Butt Lift) — and the non-surgical route, through HYAcorp hyaluronic acid injection, which has replaced Macrolane. Hyaluronic acid is a molecule naturally present in the body, biodegradable and biocompatible: a safe, reversible way to increase buttock volume.
HYAcorp is a cross-linked hyaluronic acid specifically formulated for the body: a cohesive gel that holds well in the tissues and makes it possible to reshape the buttocks with precision — increasing volume, correcting a concavity — for a supple, natural feel, with no incision.
02HYAcorp: applications and benefits
Buttock augmentation with HYAcorp answers several needs: buttocks felt to be too flat, not full enough (a profile with no curve), hollow on the sides, or showing volume irregularities that need evening out. It also reshapes and firms buttocks that have lost their tone, without necessarily enlarging them.
Its advantages over surgery: the result is immediate and adjustable during the session (the shape is checked and the volume fine-tuned), it is performed under simple local anaesthesia in the office, with no hospital stay and no recovery. HYAcorp can also improve the silhouette from behind by working on the upper part of the buttocks and the lower-back arch for more defined curves.
03HYAcorp: a safe procedure, provided the right product and the right plan
Safety rests on two things: a CE-certified product designed for the body (HYAcorp Body) and a trained doctor who injects with a cannula, in the correct plane (subcutaneous, never into the muscle). Like any hyaluronic acid, HYAcorp is absorbable and reversible (dissolvable with hyaluronidase) — a safety net that no surgery offers. By contrast, injections of low-cost « biopolymers » or industrial silicone offered abroad (fake « BBL ») are permanent and dangerous (granulomas, infections): absolutely to be avoided. HYAcorp also avoids the fat-embolism risk of the Colombian butt lift (surgical BBL).
04Before / after results
05How the procedure works
Before the procedure
Everything begins with a consultation: clinical examination, assessment of the shape of the buttocks and the quality of the skin. The doctor checks the indication — marked buttock ptosis (sagging) is a contraindication, as injections are ineffective in that case. HYAcorp is also not advised during pregnancy or breastfeeding, with an autoimmune disease, or with a skin infection in the area. The number of syringes and the volume are decided together, with pre-injection photographs and markings.
During the procedure
Lying comfortably on your stomach, after disinfection and local anaesthesia, you receive the HYAcorp hyaluronic acid injections through a fine cannula (atraumatic). The procedure is almost painless and lasts 45 minutes to 1h30 depending on the volume and the number of areas. The session ends with a massage that spreads and harmonises the gel. Depending on the goal, a second session can complete the result, at least 3 months later.
After the procedure
The result — shapely, lifted buttocks — is immediate, with the final appearance settling at 3–4 weeks, the time it takes for the swelling to subside and the product to integrate with the tissues. Recovery is mild (swelling, a few bruises at the injection points). You resume your activities, including sitting, as soon as the session ends; relative rest for 6 hours, then sport and swimming after one week; avoid UV, hammam and sauna for the first few days. A follow-up visit is scheduled at 15 days. The result lasts 12 to 24 months.

07Your questions
What is the price of a HYAcorp buttock injection in Paris?+
The price depends on the number of syringes needed (often 15 to 25 depending on the desired volume), starting from around €1,800 and up to €3,800 for a full augmentation. A precise quote is drawn up during the consultation.
Are HYAcorp injections painful?+
No, they are almost painless: the area is numbed with local anaesthesia and the product is placed with a fine, atraumatic cannula.
Is HYAcorp dangerous?+
Performed with a CE-certified product designed for the body (HYAcorp Body) by a trained doctor, it is a safe procedure: recovery is limited to swelling and a few bruises. Hyaluronic acid is also reversible (dissolvable with hyaluronidase). What is dangerous are the illegal injections of low-cost « biopolymers » or silicone offered abroad — to be avoided.
HYAcorp, lipofilling (BBL) or buttock implants: which to choose?+
HYAcorp is suited to a moderate, non-surgical augmentation, immediate but temporary (12–24 months). Buttock lipofilling (BBL) uses your own fat for a larger, longer-lasting gain, but requires liposuction and a surgical procedure. Buttock implants provide permanent volume with a prosthesis. The choice depends on the volume you want and on your anatomy.
When are the results visible and how long do they last?+
The result is visible immediately, final at 3–4 weeks, and lasts 12 to 24 months depending on the individual before gradually being absorbed.
Can touch-ups be done?+
Yes: as the effect is immediate and hyaluronic acid is adjustable, touch-ups are easy to perform with your doctor to reach exactly the result you want.
I only want to rejuvenate my buttocks, not enlarge them: is HYAcorp suitable?+
Absolutely: HYAcorp is indicated to reshape and firm buttocks that have lost their tone, without necessarily increasing their size.
Are HYAcorp and Macrolane the same thing?+
Macrolane is no longer marketed. HYAcorp replaces it advantageously, being specifically formulated and certified for this area of the body.
How many sessions and syringes are needed?+
A single session is usually enough; a second one can complete the result 3 months later. Generally 15 to 25 syringes are used depending on build and the desired volume — the doctor specifies this during the assessment.
Is there any recovery time?+
No: you leave walking and can sit down. Relative rest for 6 hours is advised, then sport and swimming can resume after one week.
