Frequently Asked Questions
What is Hyaluronic Acid?
Hyaluronic acid is a gel-like substance naturally found in the skin, joints, and eyes (vitreous body). Known for its remarkable moisture retention ability.
In the skin, it is primarily located in the dermis, where it plays a crucial role in maintaining hydration, elasticity, and firmness. However, the amount of hyaluronic acid decreases with age, leading to wrinkles and sagging.
Hyaluronic acid injections restore lost moisture and volume, smooth out wrinkles, and give the face a natural, younger look.
Recommended for concerns such as
- Nasolabial folds or marionette lines
- Sunken cheeks or temples
- Defining the shape of the nose or chin
- Adding volume to the lips
- Achieving a youthful look without surgery
- Avoiding noticeable changes or visible scars
- Seeking subtle, natural enhancements

Why Hyaluronic Acid Injections Are Popular
✓ Safe and biocompatible
Hyaluronic acid is a naturally occurring substance in the body, making it low-risk for allergic reactions and highly safe.
✓ Immediate results with minimal downtime
The effects—such as added volume and wrinkle reduction—are noticeable immediately after the injection. Since downtime is minimal, it won’t interfere with daily activities.
✓ Natural and beautiful finish
With various product types and advanced injection techniques, treatments can be tailored to achieve your desired look—whether it’s fuller cheeks, a more defined jawline, or plump, hydrated lips.
✓ Long-lasting yet reversible
Depending on the product, results can last approximately 12 to 24 months. If necessary, adjustments can be made using an enzyme called hyaluronidase, which safely dissolves the filler.
