How Should the Right Biostimulant Be Selected for Facial Rejuvenation?

In facial rejuvenation, the choice of a biostimulator should not be based solely on the patient’s age or skin quality. The essential step is to determine which tissue layer is affected by aging and the specific mechanism through which this aging occurs.

The “right” biostimulator is not necessarily the one that provides the most potent collagen stimulation, but rather the one that elicits the biological response best suited to the patient’s specific needs.

Facial aging can be categorized into four primary areas:

  1. Dermal aging: Disruption of collagen and elastin organization, and dermal thinning.
  2. Volume loss: Changes in volume within deep and superficial fat compartments.
  3. Tissue laxity: A reduction in connective tissue support and elasticity.
  4. Loss of surface quality: Fine lines, enlarged pores, uneven texture, and a dull appearance.

It is not appropriate to address all four of these mechanisms using a single type of biostimulator.

Which biostimulator for which patient?

*CaHA – Calcium Hydroxylapatite

Suitable patient profile:
✔️Medium to thick dermis
✔️Loss of tissue support and firmness
✔️Mild to moderate laxity
✔️Need for structural support along facial contours

Key advantage: In addition to stimulating collagen, it provides immediate volumetric support through its carrier gel.

*PLLA – Poly-L-Lactic Acid

Suitable patient profile:
✔️Widespread volume loss
✔️Reduced tissue support in the face
✔️Diffuse structural loss in the dermis and subcutaneous layers
✔️Patients seeking gradual, long-term biological rejuvenation

Key advantage: Promotes progressive collagen formation and long-term tissue restoration.
