Hyaluronic acid is a nonsulfated glycosaminoglycan synthesized in the human body, mainly organs and tissues. Over 50% of the HA in our bodies is located in the dermis. Hyaluronic acid is responsible for the smoothness and thickness of the skin because it can absorb large volumes of water molecules. This particular feature of HA is positively exploited by dermatologists to correct aesthetic impairments.
The US Food and Drug Agency has approved the use of dermal fillers in the following situations:
- improving the skin hydro balance
- filling up facial and neck wrinkles
- cheekbones and chin contouring
- lip shaping
- evening the facial oval
Dermal filler advantages:
- dermal fillers are completely natural, which ultimately reduces the risks of allergies and other side effects
- they are easy to apply and cause no pain (some dermal fillers even have anesthetic ingredients)
- the effect is visible on the spot and the recovery process is very short
- might have long-lasting effects depending on the fillers used and each patient's natural ability to metabolize HA
Are there any side effects? How long does the effect last?
Make sure you do not have bacterial or virus infections prior to the intervention. Especially in the areas you want to treat. The effect duration depends on the dermal filler's physical characteristics such as viscosity, concentration, and calibration. The effect usually lasts for 4-12 months but after each next intervention, this period extends.
