Introduction

Preventive aesthetics has become a rapidly growing field within aesthetic medicine, as younger patients increasingly seek subtle, non-invasive interventions to delay visible signs of aging. Among the available options, collagen-based biostimulators, such as Poly-L-lactic acid (PLLA) and Calcium Hydroxylapatite (CaHA), offer long-term dermal regeneration by stimulating neocollagenesis rather than simply filling lines or wrinkles. This case study presents the treatment of a 29-year-old female with early signs of skin aging using a collagen biostimulator as part of a preventive anti-aging approach.

 

Patient Profile and Initial Assessment

The patient, a healthy 29-year-old female with Fitzpatrick skin type II, presented with concerns about emerging fine lines on the nasolabial area, slight midface volume loss, and dullness of complexion. There was no history of cosmetic treatments or chronic skin conditions. Her main goal was to maintain youthful skin and support long-term dermal quality without altering her natural facial features.

A clinical examination revealed minimal perioral and periorbital rhytids, mild infraorbital hollowing, and decreased skin elasticity—common markers of early intrinsic aging.

 

Treatment Protocol

After evaluating treatment options, the chosen protocol involved a series of injections using a collagen biostimulator—specifically Poly-L-lactic acid (PLLA)—due to its strong neocollagenesis-inducing properties and long-term preventive effects.

Injection details:

  • Product used: Poly-L-lactic acid (reconstituted 24 hours prior)
  • Injection sites: Lateral cheeks, nasolabial fold areas, and zygomatic zone
  • Technique: Deep dermal or subdermal linear threading and fanning technique using a 25G cannula
  • Volume per session: 1 vial/session
  • Frequency: Three sessions spaced four weeks apart

Post-treatment care included facial massage instructions (five minutes, five times daily for five days) to ensure even product distribution and reduce nodule risk.

 

Clinical Outcomes

Timepoints evaluated: Baseline, 8 weeks post-final session, and 6-month follow-up.

By week 8 post-treatment, the patient exhibited:

  • Noticeable improvement in skin elasticity and radiance
  • Softening of nasolabial lines
  • Increased midface volume with no overt “filler” look
  • High patient satisfaction and confidence boost

At the 6-month evaluation, results had continued to improve subtly, indicating active collagen remodeling. No adverse events were reported other than mild swelling and bruising post-injection, which resolved within 48 hours.

 

Discussion

This case illustrates the value of using biostimulatory agents in a preventive context, particularly among younger patients seeking long-term aesthetic preservation. PLLA's gradual mechanism of action provides subtle improvements that align with patients' desire to age gracefully rather than transform dramatically.

Compared to traditional dermal fillers that add immediate volume, biostimulators offer a deeper, regenerative benefit by enhancing the skin's underlying matrix. This aligns with the shift toward skin quality optimization and prejuvenation.

The decision to treat this patient early contributed to a more natural, long-lasting improvement without the need for corrective measures in the future.

These findings are supported by literature emphasizing the preventive and regenerative role of PLLA and CaHA in youthful populations, including:

  • Recent Advances in Collagen Biostimulators for Facial Rejuvenation (Directive Publications, 2024)
  • A Multi-Layer Approach to Skin Rejuvenation (Scientific Editorial, 2023)

 

Conclusion

Collagen-based biostimulators can be effectively used for preventive aesthetic strategies in patients as young as their late twenties. Through minimally invasive treatment and gradual results, this case demonstrates that early biostimulatory interventions may play a key role in delaying visible aging, preserving facial structure, and enhancing long-term skin health.
