As we age, the natural collagen in our skin gradually declines, leading to visible signs such as volume loss, fine lines, and a loss of skin firmness. While there are many dermal filler options available, some people seek a more natural-looking, long-term improvement in skin texture and facial volume. A biostimulatory injectable offers a gradual approach to facial rejuvenation by encouraging your skin to rebuild its own collagen over time.

In this blog, we explore how a biostimulator works, who it may be suitable for, and what to expect from the treatment process.

What Is a Biostimulator and How Does It Work?

A biostimulatory injectable made from poly-L-lactic acid (PLLA), a synthetic material safely used in medical treatments for decades, offers a different approach from traditional fillers.
Unlike fillers that add immediate volume, a biostimulator works by stimulating your body’s own collagen production over time.

After injection, the PLLA microparticles are gradually absorbed by the body, triggering fibroblast activity in the cells responsible for collagen production. This process results in firmer, plumper skin with improved texture, developing gradually over several weeks to months.

The effects build progressively, making a biostimulator a subtle yet highly effective option for patients seeking natural-looking results.

What Areas Can a Biostimulator Treat?

Biostimulators are commonly used to treat areas of volume loss and skin laxity in the face. They are particularly effective for:

• Cheeks and mid-face hollowness
• Temples
• Jawline and lower face
• Chin
• Deep facial folds such as nasolabial lines (smile lines)
  

In some cases, biostimulators may be used off-label in areas such as the buttocks or thighs. These uses are not approved by the TGA and should only be performed by experienced clinicians within an appropriate clinical framework.

At Medical Aesthetic, we tailor your treatment plan to your specific facial anatomy and skin concerns.

How Is a Biostimulator Different from Dermal Fillers?

Traditional dermal fillers, such as hyaluronic acid-based injectables, provide immediate volume by physically filling areas beneath the skin. These results are visible straight away and typically last between 6 to 12 months.

A biostimulator, on the other hand, provides gradual results that appear as your body produces new collagen. It doesn’t deliver instant volume but instead improves skin density and structure over time. This makes it a preferred choice for those seeking a progressive, natural outcome.

For those interested in combining treatments, Sculptra may be integrated into a broader skin rejuvenation plan alongside premium dermal fillers or collagen-stimulating treatments.

What Does the Treatment Process Involve?

A typical biostimulator treatment begins with a detailed consultation to assess your skin condition and suitability for the procedure. At your appointment, your practitioner will cleanse the treatment area and administer a series of small injections using a fine needle or cannula.

Each session takes around 30 to 45 minutes, and most people can return to normal activities shortly after. Mild swelling, tenderness, or bruising may occur in the days following treatment, usually resolving without intervention.

For optimal results, a series of treatments is usually recommended, often spaced 4 to 6 weeks apart. The number of sessions will depend on your age, skin quality, and aesthetic goals.

When Will I See Results and How Long Do They Last?

Unlike traditional fillers, biostimulators do not provide immediate results. Collagen stimulation takes time, so visible improvements generally begin to appear after 4 to 6 weeks, continuing to enhance over several months.

Clients often notice increased skin firmness, improved texture, and more youthful contours. In some cases, results may last up to two years or longer, depending on factors such as skin type, age, and lifestyle.

It’s important to note that individual results can vary, and ongoing maintenance may be required to sustain the effects.

Is a Biostimulator Suitable for Everyone?

A biostimulator is typically best suited for individuals seeking gradual facial rejuvenation without the appearance of having had “work done.” It may be ideal if you:

• Have mild to moderate volume loss
  
• Prefer long-term collagen stimulation
  
• Want subtle, natural-looking changes over time
  

However, it may not be suitable for those looking for immediate volume or correction, or individuals with certain medical conditions or autoimmune disorders. A comprehensive consultation at Medical Aesthetic will determine whether this treatment is appropriate for you.
