Which is the best Collagen Bio-Stimulator for you?

Choosing between PLLA, CaHA, or a combination depends on the patient’s goals, timeline, and skin condition:

  • For natural, slow-developing results with long-term benefits, PLLA is the best choice.

  • For immediate volume and visible lift, CaHA is preferred.

  • For those wanting both instant and long-term effects, the combination approach offers an excellent solution when administered by an experienced injector.

Each treatment has its own strengths, and a personalized consultation is key to determining the most effective plan based on age, facial structure, and desired outcome.

    • Gradual results: Stimulates the body to produce collagen over time (4–8 weeks).

    • Long-lasting: Results can last up to 2+ years.

    • Ideal for: Full-face rejuvenation, skin quality improvement, and deep tissue regeneration.

    • Requires post-treatment massage to prevent nodules.

    • Immediate results: Provides instant volume and lift with continued collagen stimulation.

    • Durable but slightly shorter duration: Lasts around 12–18 months.

    • Ideal for: Structural support in areas like the jawline, cheeks, and nasolabial folds.

    • No post-treatment massage required.The growth factors help revitalize hair follicles, leading to thicker and fuller hair. 

    • Dual benefit: Immediate lift from CaHA + long-term collagen boost from PLLA.

    • Balanced approach: Offers both short-term correction and sustained rejuvenation.

    • Ideal for: Patients seeking comprehensive, layered facial restoration.

    • Customizable but may be off-label depending on the market.
