What is Collagen Stimulator?
Collagen stimulator injections are a type of aesthetic treatment that encourages your skin to produce more of its own natural collagen. Rather than creating immediate filling effects, these treatments work gradually to improve the skin’s underlying structure.
Restore firmness & elasticity
Improve smoothness & texture
Lift sagging areas for a more youthful contour
💡Collagen acts like scaffolding beneath your skin — when it weakens, the skin can lose firmness. Collagen stimulators encourage the body to rebuild this structure naturally over time.
The Importance of Collagen for Healthy Skin
As we age, our body naturally produces less collagen, the protein that keeps our skin smooth, lifted, and resilient.
Collagen is like the scaffolding beneath our skin. When there’s plenty of it, the skin looks plump and youthful. But over time, that structure starts to weaken — and that’s when we begin to see fine lines, sagging, or a tired appearance that doesn’t reflect how we feel inside.
Collagen-stimulating treatments work by reactivating that natural process, helping your skin gradually restore its strength, volume, and glow. It’s not about changing how you look, but about helping your skin feel healthier, firmer, and more like you again.
Types of Collagen Booster Injections
There are 4 types available at Zion Aesthetic Clinic, each with unique benefits:

- Improve skin firmness and structural support
- Address areas affected by skin laxity
- Improve Deep smile lines or marionette lines
2. Poly-D,L-Lactic Acid (PDLLA)
PDLLA injections refer to injectable treatments that contain Poly-D,L-Lactic Acid, a biocompatible and biodegradable substance that stimulates natural collagen production in the skin over time.
- Improve skin firmness and elasticity

4. Calcium Hydroxylapatite (CAHA)
CaHA injections refer to injectable treatments that contain Calcium Hydroxylapatite, a biocompatible substance that provides both immediate volume and long-term collagen stimulation.

3. Polycaprolactone (PCL)

What is the treatment process like?
01.
Consultation and Assessment
Before the treatment, you will undergo a consultation whereby your doctor will assess your skin condition, and discuss your goals. Thereafter, your doctor will recommend the most suitable type of collagen biostimulator based on your facial anatomy and areas of concerns.
02.
Customised Treatment Plan
A customised treatment plan will be created including:
- Type of Collagen Stimulator Injection
- Treatment areas
- Number of sessions
03.
Treatment Process
Numbing cream will be applied for 30 minutes to enhance comfort. After the numbing cream is effective, your doctor will inject the collagen stimulating injection. The treatment will be around 30 to 45 minutes, depending on the area.
04.
Recovery and Aftercare
You may notice mild swelling, redness, or bruising at the injection sites. However, these side effects are temporary and usually resolve within a few days.
How Much Does The Collagen Treatment Cost?
The cost of treatment typically ranges between $650 and $1,080, depending on the amount of product used and your individual skin needs.
During your consultation, the doctor will take a closer look at your skin and recommend a treatment plan that suits your goals. The final cost will be discussed before proceeding so you have a clear understanding of the treatment approach.
Which Collagen Biostimulator suits me best?
Every collagen biostimulator has its unique strengths, and the most suitable option for you depends on your skin condition, aesthetic goals, and treatment areas. During your consultation, your doctor will assess your needs and recommend the most appropriate collagen biostimulator for natural-looking, long-lasting results.
