Objectives: To present the rationale, indications, and clinical experience with the use of injectable biostimulatory agents—PLLA and PDLLA—for non-surgical buttocks augmentation, focusing on regenerative volume restoration and tissue remodeling.

Introduction: Non-surgical buttocks augmentation has become increasingly popular among patients seeking enhanced contour and firmness without the downtime and risks associated with surgery. Poly-L-lactic acid (PLLA) and poly-D,L-lactic acid (PDLLA) are biocompatible, biodegradable polymers that act as collagen stimulators. When injected in a diluted form into the subdermal or deep dermal layers, they provide gradual, natural-looking volume by stimulating neocollagenesis and improving skin texture. This approach offers a regenerative, progressive enhancement rather than immediate volumization.

Materials / method: Patients underwent buttocks augmentation using reconstituted PLLA or PDLLA suspensions injected via cannula into the subcutaneous tissue in a fanning or cross-hatch pattern. Injection plans were tailored based on anatomical assessment, volume requirements, and tissue quality. Treatment sessions were spaced 4–6 weeks apart, with an average of 2–3 sessions per patient. Post-treatment massage protocols were followed to ensure even distribution. Candidates were selected based on the absence of contraindications such as autoimmune disease, infection, or prior complications with fillers.

Results: Progressive volume enhancement and improved skin elasticity were observed over a 3–6 month period, with high levels of patient satisfaction regarding shape, firmness, and natural appearance. Results were subtle yet cumulative, aligning with patient expectations for a non-surgical solution. The treatment was well tolerated, with minimal adverse effects such as temporary nodularity or bruising. Maintenance treatments were considered after 18–24 months.

Conclusion: PLLA and PDLLA offer a safe and effective option for non-surgical buttocks augmentation, combining regenerative stimulation with gradual, natural contouring. These injectables represent a valuable tool in body aesthetic medicine, particularly for patients seeking subtle enhancement with minimal downtime. Proper injection technique, dilution protocol, and patient education are essential for achieving optimal outcomes.

Objectives: The author compares his experience in injectables at the male genital area over the past 3 years.

Introduction: The author describes his technique at injection at the Penis with hialuronic acid versus biostimulators over the past 3 years

Materials / method: Over the past 3 years, the author has treated more than 25 patients with the complains of micropenis.He is using the PDLLA as biostimulator and a low G PRIME hialuronic acid .

Results: Over 25 patients treated , only 2 patients have complain about the results , one with a small nodule of biostimulator wich has been fully diluted in one session with hialuronidasis and saline solution
The other patient presented also a nodule of hialuronic acid but preferred not being treated due to the risk of loosing the volume result

Conclusion: The description of the TECHINIQUE is very simple and in the hands of skillfull doctors who are used to the injections filling techiniques , will be very well accepted
