Summary
The step-by-step Phi technique uses the golden ratio for safe hyaluronic acid lip augmentation, achieving natural results with minimal side effects. This method ensures precise injections for enhanced facial aesthetics.
Area of Science:
- Aesthetic medicine
- Dermatology
- Plastic surgery
Background:
- Lip augmentation is crucial for facial aesthetics.
- Hyaluronic acid (HA) is a common dermal filler.
- Safe and natural-looking lip enhancement techniques are in demand.
Purpose of the Study:
- To describe a novel, safe lip augmentation technique using hyaluronic acid.
- To apply the golden ratio (Φ) for precise injection point identification.
- To evaluate the efficacy and safety of the step-by-step Φ technique.
Main Methods:
- The step-by-step Φ technique involves precise HA injections guided by the golden ratio.
- A caliper identifies 3-4 injection points per lip half.
- Small volumes (0.01-0.05 ml) of HA are injected, with sessions spaced 15-30 days apart if needed.
Main Results:
- The technique was performed on 833 patients with high satisfaction rates.
- It effectively avoids severe complications like embolism or occlusion.
- Common side effects included mild swelling, redness, and pain.
Conclusions:
- The step-by-step Φ technique offers a safe and effective method for lip augmentation.
- The technique is easy to learn and perform.
- It consistently delivers natural-looking results.
