Polylactic acid (PLA) is an FDA-approved, biocompatible and biodegradable substance that acts as a biostimulant, triggering the body’s own collagen production when injected under the skin.
When applied for buttock augmentation:
• It adds volume to the buttock area,
• Strengthens its shape,
• Creates a firming and lifting effect.
Lanluma® and Sculptra® are the two best-known brands that contain polylactic acid and work based on collagen stimulation.
This application, unlike classic fillers, “does not inject volume but enables the skin to produce its own volume.” This makes the result more natural, gradually developing but long-lasting.
How does it work?
Polylactic acid-based fillers (Lanluma and Sculptra) add volume to the buttock area, tighten and shape the skin by stimulating the collagen production naturally found in the body.
• When the filler substance is injected under the skin, it stimulates fibroblasts and encourages the body to produce its own collagen.
• Unlike hyaluronic acid fillers, it does not give instant volume but provides natural fullness and tightening over time.
• It offers a non-surgical solution especially for flat or sagging buttocks.
What are the benefits?
• Provides a fuller, firmer and lifted buttock appearance.
• Increases skin elasticity and prevents sagging.
• Reduces cellulite (orange-peel appearance) and provides smoother skin.
• Stimulates natural collagen production and creates long-lasting effects.
• A safe and minimally invasive procedure that does not require surgery.
• A very safe alternative to fat injection or silicone implants.
Does it provide a natural appearance?
Yes, polylactic acid fillers do not create sudden or artificial fullness. Instead, they increase collagen production over time, allowing the buttocks to shape naturally.
Who is it suitable for?
• Individuals experiencing volume loss in the buttock area.
• Those who want to improve flat or undefined buttock contours.
• Those who want round and shaped buttocks without surgery
• Individuals with cellulite or dimpling in the buttocks.
• Those seeking non-surgical and natural buttock enhancement.
• Patients who do not have enough fat tissue for fat transfer.
• Those with early signs of skin laxity or sagging.
Which areas can it be applied to?
• Upper and lower parts of the buttocks.
• Depressions along the buttock contour.
• The gluteal region (above the gluteal muscles).
When are the results seen?
In polylactic acid fillers, results appear later compared to classic fillers but are more natural and long-lasting. Because these products do not directly add volume but stimulate the body to produce its own collagen.
The effect timeline is as follows:
• First 24–48 hours: Temporary fullness may be seen due to swelling and water retention after the injection. This is not the permanent effect.
• 3–4 weeks: The body begins producing collagen. The first real increase in volume becomes noticeable.
• 6–12 weeks: Collagen production increases, the buttock contours become fuller and shaping becomes visible.
• At 3 months: Results reach their maximum. Subcutaneous volume increases, firmness and contour become defined.
Remember: The effect develops slowly, requiring patience, but this makes the result more natural and long-lasting.
How long does it last?
• It lasts between 2 and 3 years.
• It may vary depending on age, skin structure, and lifestyle.
Is one session enough or is repetition needed?
Polylactic acid fillers (Sculptra & Lanluma) may be effective in a single session, but for ideal and long-lasting results, more than one session is usually recommended.
Why is repetition needed?
These fillers do not “give volume”; they stimulate the body to produce collagen. Since collagen production varies between individuals, the body may require multiple stimulations for optimal shaping and tightening.
Session planning:
• For slim individuals or those wanting minimal volume:
1–2 sessions may be sufficient.
• For those seeking noticeable contour enhancement, lifting or shaping:
2–3 sessions are recommended.
Sessions are typically spaced 4–6 weeks apart.
Each application creates a cumulative effect, allowing the results to settle gradually.
Polylactic acid fillers do not promise a “one-session miracle.”
But with a few sessions and patience, they provide non-surgical, natural and long-lasting body contouring.
How long does the procedure take?
• It is a procedure that takes approximately 45–60 minutes.
Is it a painful procedure?
• There may be mild stinging during needle injection.
• Anesthetic cream is used to minimize pain.
Is anesthesia required?
• Yes, local anesthetic cream is applied.
• For some patients, an injectable local anesthetic is also added.
Can you return to social life immediately after the procedure?
• Yes, social life can generally be resumed immediately after polylactic acid buttock fillers.
Since the procedure is not surgical, the recovery period is very short.
However, resting for the first 24 hours is recommended.
• Swelling and slight bruising may occur but do not hinder daily activities.
What should be considered after the procedure?
Recovery after polylactic acid filler is usually comfortable, but there are important points to consider to increase the effectiveness of the application and prevent unwanted effects.
1. Massage is very important!
For 5 days after the procedure, it is recommended to perform massage 5 times a day for 5 minutes.
This helps the product distribute properly under the skin and prevents unwanted nodule formation.
2. First 24–48 hours:
• Avoid heavy exercise, prolonged sitting or trauma. Use a sitting cushion.
• Hot shower, sauna, Turkish bath and tanning beds are not recommended. Warm showers are allowed.
• Choose loose clothing instead of tight or pressure-inducing garments (such as leggings or corsets).
3. Avoid touching and applying pressure to the area
Since the subcutaneous structure begins to reshape after the procedure, applying pressure to the area in the first days may negatively affect volume distribution.
4. Limit alcohol and smoking
These substances impair circulation and may slow collagen production. Therefore, consumption is not recommended for at least 3–5 days.
5. Drink plenty of water, consume protein-rich foods
Adequate fluid and building blocks must be provided to the body to support collagen production.
Result:
The most critical part of the post-procedure period is massage and attentive care during the first 5 days. Applying this simple but effective care ensures natural, homogeneous and long-lasting results.
Is the procedure safe?
• Yes, it is safe when FDA-approved polylactic acid-based fillers are used.
• Since it stimulates the body’s own collagen production, it offers long-term, natural results.
Does it have side effects?
• Temporary swelling, redness, bruising and tenderness may occur.
Can it be applied to everyone?
• Not recommended for pregnant and breastfeeding women.
• Not suitable for patients with bleeding disorders or active skin infections.
• Caution is required for individuals with immune system disorders.
Will there be redness, bruising or swelling after the procedure?
• Yes, mild redness and bruising may occur at the injection site, but it resolves within 3–7 days.
Is extra care needed after the procedure?
Yes, post-treatment care for polylactic acid fillers is critically important for the success of the procedure. Because this filler is unlike classic volumizing fillers and works by triggering collagen production, aftercare directly affects its effectiveness.
The most important step: The 5-5-5 Massage Rule
• 5 times a day,
• For 5 minutes,
• For 5 days
gently massage the treated area with circular motions.
This ensures even distribution of the product, prevents nodule formation and supports collagen production.
Other important considerations:
• Avoid excessive exercise, trauma and heat (sauna, Turkish bath, tanning beds) for the first 48 hours. Warm showers are allowed.
• Avoid tight clothing; allow the area to breathe and support circulation.
• Drinking plenty of water supports collagen production.
• High-protein nutrition benefits fibroblast activity.
• Avoid pressure on the treated area on the first day.
Result:
For polylactic acid fillers, the post-procedure care routine is at least as important as the procedure itself for an effective and natural result.
Is regular repetition necessary?
• It is not mandatory, but repeating every 2–3 years is recommended to maintain long-lasting results.
This treatment is not an “instant volume injection” but a gradual and sustainable restructuring process.
Why is repetition recommended?
• Collagen production decreases over time.
• Body shape may change over the years due to aging, weight fluctuations and lifestyle.
• Regular stimulation helps maintain firmness and shape of the buttocks.
For Those Who Say “I Want Buttock Filler But I’m Afraid”
Recently, posts on social media about unwanted outcomes from certain buttock filler procedures have created serious prejudice about these treatments.
In particular, some permanent and questionable substances used in the past could cause spreading in the body, formation of hard nodules or complications that could not be reversed.
However, the new-generation buttock fillers used today are absolutely not the same as those materials.
The product we use in our clinic is temporary, metabolizable, and contains substances that stimulate the body to produce its own collagen.
It distributes itself in the tissue in a controlled manner, is fully absorbed over time, and does not carry risks such as spreading to internal organs.
Outstanding Features of the New-Generation Buttock Filler:
• The duration of permanence is controlled; it is safely broken down by the body.
• Its content is FDA-approved and has been safely used for many years in facial and body aesthetics.
• By increasing subcutaneous collagen production, it provides not only volume but also tightening and rejuvenation.
• It does not carry risks such as spreading to organs or damaging tissue.
• After the procedure, daily routine can be resumed safely without interrupting social life.
Conclusion
Buttock filler, when performed with the right product and by expert hands, offers extremely safe and natural-looking results.
As a clinic, we use only Ministry of Health-approved, scientifically supported and ÜTS-registered products.
It is very important not to confuse this reliable method with negative examples from the past and to proceed with accurate information.
