Biostimulation Overview

True skin rejuvenation begins beneath the surface, where collagen, elastin, and cellular vitality are restored from within. Biostimulation represents the next generation of aesthetic medicine, harnessing the body’s natural regenerative power to revitalise the skin without changing its unique contours. Through gentle, precision-based injections of biostimulatory agents, this advanced approach awakens fibroblast activity, enhances hydration, and rebuilds the skin’s internal architecture. The result? A gradual, authentic radiance that reflects health, balance, and timeless beauty.

Bio-stimulators vs Dermal Volumisers: The Ultimate Guide
Join Dr Maureen Allem as she explains the essential differences between bio-stimulators and dermal volumisers (fillers) in modern aesthetic medicine. Discover how injectable biostimulatory treatments such as CaHA, PLLA and PCL work to stimulate collagen, improve skin quality, and support long-term rejuvenation, compared to dermal fillers, which restore lost volume, lift sagging tissue, and enhance facial contours. Whether you’re exploring non-surgical skin rejuvenation, collagen-stimulating injections, or personalised combination treatments, this video provides clear medical insight to help you understand which approach best suits your ageing concerns and aesthetic goals.

Injectable mesotherapy with biostimulatory agents is a state-of-the-art, minimally invasive aesthetic procedure that delivers micro-injections of specialised solutions into the dermal layer of the skin. These solutions blend vitamins, minerals, amino acids, hyaluronic acid, and advanced biostimulatory compounds, such as Calcium hydroxyapatite (CaHA), poly-L-lactic acid (PLLA), or Polycaprolactone (PCL), to initiate the skin’s own regeneration processes.

Key Benefits of Biostimulation

  • Stimulates the skin’s natural regenerative processes to support long-term collagen and elastin production.
  • Improves skin texture, luminosity, elasticity and firmness.
  • Suitable for addressing early to moderate signs of ageing, skin laxity and mild volume loss.
  • Provides gradual, natural-looking rejuvenation with minimal downtime and low risk of adverse effects.

How Biostimulation Differs from Traditional Mesotherapy and Dermal Fillers

  • Traditional mesotherapy typically injects hydrating and revitalising cocktails (vitamins, amino acids, hyaluronic acid) to refresh the skin, but does not substantially stimulate collagen synthesis.
  • Biostimulatory mesotherapy, however, targets the deeper dermal layers and harnesses active compounds (CaHA, PLLA, PCL) to drive actual tissue remodelling rather than just superficial improvement.
  • Dermal fillers, by contrast, primarily add volume and structural support; biostimulation focuses on encouraging the skin to strengthen itself from within rather than just filling deficits.

Biostimulation vs Biorevitalisation vs Bioremodeling

  • Biostimulation: Treatment that activates the body’s own dermal regeneration—especially fibroblast activity, to increase collagen, elastin and hyaluronic acid production. Common active substances: CaHA, PLLA, PCL, sometimes combined with hyaluronic acid. Ideal for improving “inside-out” skin quality, rather than adding volume.
  • Biorevitalisation: Non-volumising minimally invasive injection of biologically active compounds (concentrated hyaluronic acid, vitamins, peptides, antioxidants) for deep skin hydration and tone restoration. Focused on revitalising cell metabolism rather than structural change.
  • Bioremodeling: High-concentration hyaluronic acids or specialised compounds injected at deeper dermal/subcutaneous layers to remodel the skin’s deeper architecture. Designed for sagging, loss of elasticity and deeper wrinkles, closer to structural lift than mere surface improvement. 

Who Is This For?

Individuals who may benefit include those with:

It’s also ideal as a preventive skin rejuvenation strategy for patients seeking subtle, natural results with low downtime. Extensive volume loss or advanced sagging may require bioremodeling or volumising fillers (or both) for optimal results.

questions

Are biostimulation and bio-remodelling treatments available at all Skin Renewal Clinics?
What exactly is biostimulation, and how does it differ from traditional mesotherapy?

Biostimulation is a non-surgical rejuvenation technique that utilises injectable biostimulators to stimulate your skin’s natural regeneration processes. While traditional mesotherapy focuses on hydrating and nourishing the skin’s surface, biostimulation goes deeper, awakening fibroblast activity to boost collagen, elastin, and hyaluronic acid production. Over time, this results in firmer, smoother, and more radiant skin that looks naturally refreshed rather than “filled.”

Which ingredients or compounds are used in biostimulation treatments?

Depending on your specific skin concerns, the biostimulatory solution may contain compounds such as Calcium Hydroxyapatite (CaHA), poly-L-lactic acid (PLLA), or Polycaprolactone (PCL) - all of which are scientifically proven to stimulate collagen production. These may be combined with hyaluronic acid, vitamins, peptides, and amino acids to enhance hydration and support cellular metabolism. Your Skin Renewal doctor will select the most suitable formulation for your skin type and treatment goals.

What areas can be treated during a treatment?

Injectable mesotherapy with biostimulators can be performed on the face, neck, décolletage, and hands, areas most prone to early signs of ageing and loss of elasticity. It is especially effective for improving fine lines, crepiness, dullness, and overall skin quality. Some protocols may also be applied to the upper arms or knees, where skin laxity is mild to moderate.

How many sessions will you need, and when can you expect to see results?

Results are progressive rather than instant. Most patients notice an improvement in skin tone and hydration within a few days, while visible collagen and elastin renewal becomes apparent after 4–6 weeks.

What can you expect during and after the procedure?

During the treatment, a fine needle or cannula is used to deliver micro-injections into targeted areas. The procedure is generally well-tolerated and can be performed with topical anaesthesia for added comfort. After treatment, mild redness or pinpoint swelling may appear but usually resolves within 24–48 hours. There is no significant downtime; most patients return to normal activities immediately.

Are biostimulatory injections safe?

Yes. When performed by an experienced medical professional using approved products, biostimulatory injections are considered safe and well-tolerated. The substances used (CaHA, PLLA, and PCL) are biocompatible and biodegradable, meaning the body naturally absorbs them over time. Minor side effects, such as temporary redness, bruising, or swelling, are generally short-lived.

How long do results last?

Results develop gradually and can last 12–24 months, depending on the specific product used, your age, skin condition, and lifestyle factors such as sun exposure and smoking. Because biostimulation works by stimulating your own collagen, the improvements are long-lasting and natural-looking, not dependent on the product remaining under the skin.

Can biostimulation be combined with other aesthetic treatments?

Absolutely. Biostimulation works effectively as part of a combination protocol, enhancing the results of other rejuvenating treatments, such as microneedling, laser skin resurfacing, radiofrequency tightening, carboxytherapy, or chemical peels. It can also complement bioremodeling or skin booster treatments to address different layers of the skin simultaneously, a holistic approach that delivers the “multiplier effect” for which Skin Renewal is known.

Who is the ideal candidate for biostimulation?

Ideal candidates are individuals experiencing early to moderate signs of ageing, mild skin laxity, or a dull complexion who wish to improve skin quality without surgery or excessive volume enhancement. It’s also a perfect choice for younger patients seeking preventative rejuvenation and for those who prefer gradual, natural-looking results.

Is there anyone who should avoid this treatment?

Biostimulation is not recommended for pregnant or breastfeeding women, or for individuals with active skin infections, severe inflammation, or autoimmune conditions that affect wound healing. A complete medical consultation with a Skin Renewal doctor will determine whether you’re an appropriate candidate and ensure your treatment plan is entirely safe and personalised.
