Basic Knowledge of Hyaluronic Acid
What is Hyaluronic Acid?
Hyaluronic acid is an artificial injectable substance that provides volume.
It is highly safe and widely used globally.
It is not only used in aesthetic medicine but also in orthopedics and ophthalmology, making it a safe choice for patients.
Types of Hyaluronic Acid
Many companies create various hyaluronic acid formulations.
Major brands include Allergan’s Juvederm, Teoxane's RHA, Restylane’s Restylane Lift, Belotero, and Redensity.
Each company produces hyaluronic acid with different levels of firmness.
Effects of Hyaluronic Acid
It helps to plump tissues.
By considering where and how much volume to add, you can design and inject the appropriate amount.
By filling in specific areas, you can improve issues like hollowed cheeks, dark circles, wrinkles, and sagging.
Choosing Hyaluronic Acid for Different Areas
Hyaluronic Acid for the Eye Area
The skin around the eyes is thin, so softer hyaluronic acid is suitable.
Examples include Volbella or RHA1.
Injecting near the bone structure helps to support the orbital area and fat.
Hyaluronic Acid for Nasolabial Folds
For injections over the bone structure, firmer hyaluronic acid is ideal.
Products like Voluma, Volux, or RHA4 are commonly used.
For injections under the skin, a balance between softness and firmness is key.
Voluma, Volift, or RHA3 are commonly used for these areas.
Hyaluronic Acid for Chin and Contouring
For the chin and overall facial contouring, hyaluronic acid is injected to support the bone structure.
Firm products like Volux or Restylane Defyne are typically used.
Hyaluronic Acid Injection Methods
Needle vs. Cannula Injection
Hyaluronic acid can be injected with a needle or a cannula.
Needles allow for precise placement in specific layers and areas.
Cannulas reduce risks like bruising or blood flow issues and allow for broader coverage with fewer injection points.
Anesthesia Options during Treatment
For repeated injections, topical anesthesia works effectively.
For fewer injections, nitrous oxide (laughing gas) is often preferred.
Pain Management and Comfort
Pain is more noticeable when tense.
We encourage you to relax as much as possible.

Longevity and Maintenance of Hyaluronic Acid
Expected Duration
The longevity of hyaluronic acid depends on the product, with some lasting as short as 6 months, and others up to 3 years.
Most products last around 1-2 years.
Importance of Regular Maintenance
Hyaluronic acid gradually dissolves over time, and facial changes occur with aging.
Regular maintenance is recommended to ensure continued results.
Tips to Improve Longevity
Avoid excessive pressure on treated areas.
Difference Between Hyaluronic Acid and Collagen
Roles of Hyaluronic Acid and Collagen
Hyaluronic acid helps retain moisture, resulting in hydrated, dewy skin.
Collagen provides elasticity, leading to firmer, more youthful skin.
Both are essential components for beautiful skin.
Combining Both for Enhanced Effects
Younger skin typically has higher levels of both collagen and hyaluronic acid.
Anti-aging effects can be achieved by targeting both collagen and hyaluronic acid.
Which Should You Choose?
If you have dry skin, hyaluronic acid is ideal.
For those with thinning skin, collagen is more appropriate.
However, having both is the ideal solution.
