What is Hyaluronic Acid?
Hyaluronic acid is a natural substance that can rejuvenate the skin and enhance the volume of subcutaneous tissues when injected into the dermal layer of skin. Hyaluronic acid injections typically last 6 to 12 months. Results may vary based on the product and individual metabolism. Maintenance treatments may be necessary for sustained effects.
Injection Outcomes
Doctors’ experience and technique: Proper injection depth, dosage, and technique are crucial. Improper injection can lead to uneven distribution of the material. Shallow injections or excessive quantity at a single point can cause subcutaneous nodules, known as granulomas.
Individual Factors: The absorption and reaction within the body can vary based on individual constitution, immune response, metabolic rate, and initial skin condition.
Item | Advantages | Disadvantages |
Hyaluronic Acid | Immediate effect; can be dissolved if unsatisfactory; higher safety | Shorter duration, generally 6-12 months |
Side Effects and Precautions
Post-Injection Filler Side Effects
Common side effects include redness, itch, discomfort, bruise (temporary side effects) at the injection site, usually temporary and subsiding within a few days to two weeks.
Why Does Redness Occur After Injection?
Immune Response: The immune system may treat the injected material as a foreign substance, causing an immune response. As the body adapts to the material, the redness will gradually subside.
Improper Injection: Damage to blood vessels or nerves during injection, shallow injection depth, or excessive injection volume can cause local tissue compression or damage, leading to redness and requiring medical attention.
Infection: There is a risk of infection during the injection process. If symptoms like redness, pain, fever, or pus appear post-injection, seek medical attention promptly.
Other Potential Side Effects
Any filler can potentially cause:
Obstruction of blood supply by the injected material, leading to local tissue necrosis and permanent scarring.
Vascular embolism by the injected material, resulting in blindness and stroke.
Post-Injection Guidelines
Within 48 hours post-injection, apply cold compresses moderately to the injection site; avoid alcohol, strenuous exercise, and spicy foods.
Can Unsatisfactory Results Be Reversed?
Hyaluronic acid can be dissolved with hyaluronidase if results are unsatisfactory.
Pregnant and breastfeeding women.
Individuals with allergies.
Those with inflammatory infections at the injection site.
Patients with coagulation disorders.
Individuals with immune system abnormalities.
