Hyaluronic acid facial fillers are the world’s most popular dermal fillers. But what exactly are they, how do they work, and are they really safe? Dr. Tatiana Leal answers all the questions.
What is hyaluronic acid?
Hyaluronic acid is a molecule that naturally exists in our bodies, especially in the skin, joints, and eyes. Its main function is water retention: it can hold up to 1,000 times its weight in water, making it an unparalleled hydrating agent.
With age (beginning around 25-30 years), natural hyaluronic acid production decreases, contributing to volume loss, wrinkle formation, and reduced skin luminosity.
How does hyaluronic acid work as a dermal filler?
When used as an injectable dermal filler in aesthetic medicine, hyaluronic acid acts in several ways:
- Physical filling: occupies the space where volume has been lost, softening folds and wrinkles
- Deep hydration: attracts and retains water in the treated area, improving skin quality
- Collagen stimulation: the injection process and the presence of hyaluronic acid stimulate natural collagen production

Which facial areas can be treated with hyaluronic acid?
Hyaluronic acid dermal fillers can be applied to: lips (volume and definition), under-eye hollows and tear troughs, nasolabial folds, cheeks (volume restoration), chin (harmonization), marionette lines, temples, and forehead wrinkles.
Is hyaluronic acid reversible with hyaluronidase?
Yes — and this is one of hyaluronic acid’s greatest advantages over other fillers. Hyaluronidase is an enzyme that can dissolve hyaluronic acid in a controlled and rapid manner.
If you’re not satisfied with the result, if there’s a complication, or if you simply want to reverse the treatment, hyaluronidase can undo the effect within hours. At our clinic, we always have hyaluronidase available for any adjustment or correction needed.
This reversibility is one of the main reasons hyaluronic acid dermal fillers are the most widely used globally.
What brands are used? Are they FDA-equivalent approved?
We exclusively use premium brands with FDA-equivalent approval: Restylane, Juvederm (Allergan), and Belotero. All undergo rigorous international clinical testing and have been used safely in millions of procedures worldwide.

How long do hyaluronic acid filler results last?
Duration varies by area: lips metabolize faster (6-12 months); under-eye and cheek fillers typically last 18-24 months. Most areas show results lasting 12-18 months.

Cost savings: hyaluronic acid fillers in Bogotá vs the US
International patients consistently save 60-70% on hyaluronic acid dermal filler treatments in Bogotá compared to US prices, using the same premium brands (Restylane, Juvederm, Belotero). This makes Bogotá one of the most popular medical tourism destinations for aesthetic treatments.
Conclusion
Hyaluronic acid facial fillers offer the best safety profile of any dermal filler: natural, internationally approved, reversible with hyaluronidase, and with immediate natural-looking results.
