What Is Personalized PRP Injection?
Personalized PRP injections area treatment that injects a formulation combining PRP (platelet-rich plasma) with added FGF (fibroblast growth factor)..
PRP: An ingredient extracted from your own blood, rich in growth factors
FGF: Fibroblast growth factor. An ingredient that powerfully promotes skin regeneration
By combining these two, PRPF injection is designed to deliver more powerful results than conventional PRP therapy.
Furthermore, at Smart Skin Clinic, we maximize the results by doing the following:
✔️ Precise diagnosis of each individual’s condition
✔️ Tailor-made dosage design
✔️ Precise injection by a skilled doctor

Three Features of Personalized PRP Injection
1. Long-term results and cost performance
The effecttypically lasts 5 years or more. Because the results of a single treatment last for an extended period, it offers excellent cost performance.
2. Natural rejuvenation effect
Because it uses ingredients derived from your own body, the results look natural. It enhances the skin's own regenerative power, so there is no unnatural appearance.
3. Customized treatment
At our clinic, we adjust the concentration and injection volume and design the injection placement to suit each patient’s skin condition and goals.
The Mechanism of Personalized PRP Injection: Why Does It Work on Dark Circles?
The main reasons personalized PRP injections are effective for dark circles under the eyes are as follows:Four Mechanismsis due to
1. Promoting Collagen Production
The platelet-derived growth factor (PDGF) and FGF contained in personalized PRP injections stimulate fibroblasts. As a result, collagen production is promoted, improving skin firmness and elasticity. This helps improve the thin, sagging skin that causes dark circles.
2. Promoting Angiogenesis
Vascular endothelial growth factor (VEGF) promotes the formation of new blood vessels. This improves circulation and helps relieve the blood pooling that is one cause of blue-toned dark circles.
3. Improving Pigmentation
Transforming growth factor beta (TGF-β) helps regulate melanocyte activity, which in turn suppresses the excess melanin production that causes brown dark circles.
4. Tissue Repair and Regeneration
Insulin-like growth factor (IGF) promotes cell proliferation and differentiation, accelerating the repair and regeneration of damaged skin tissue and improving overall skin quality.
Together, these mechanisms work in combination to help improve various types of dark circles.

Comparison with Other Treatments
1. Comparison with Hyaluronic Acid Injection
・Personalized PRP injection: a low allergy risk thanks to autologous components, and long-term skin regeneration effects
・Hyaluronic acid: Provides an immediate volumizing effect, but is absorbed within 6 to 12 months. It also carries a risk of vascular occlusion, requiring caution when injected near blood vessels such as under the eyes or between the brows
2. Comparison with Laser Treatment
・Personalized PRP injection: works deep into the skin for long-lasting results
・Laser: Mainly addresses surface-level concerns and requires multiple sessions
3. Comparison with Surgical Procedures
・Personalized PRP injection: non-invasive, with quick recovery and natural-looking results
・Surgical procedures: Can achieve dramatic change, but carry greater risk and downtime
Personalized PRP Injection Procedure
- Blood draw: A small amount of blood is drawn from the patient's arm
- PRP extraction: PRP is extracted using a specialized centrifuge
- FGF addition: FGF is added to the extracted PRP
- Injection design: Individually designed to address the specific concerns you want to resolve
- Injection: A fine needle is used to inject into the skin under the eyes
The needles used are extremely fine, minimizing pain. Anesthetic cream can also be used if needed.
