Restylane is a hyaluronic acid-based dermal filler designed to restore facial volume, smooth wrinkles, and enhance natural facial contours. Following the correct injection protocol helps maximize treatment results while minimizing the risk of complications.
Before the Procedure
Before beginning treatment, practitioners should:
Explain the indications, expected outcomes, possible side effects, and necessary precautions to the patient.
Assess whether pain management is required and discuss available anesthetic options.
Obtain informed consent before proceeding with the treatment.
Maintain strict aseptic technique throughout the entire procedure.
Thoroughly cleanse and disinfect the treatment area using an appropriate antiseptic solution.
Preparing the Syringe
Proper syringe preparation is essential for safe and effective injections.
Hold the glass syringe barrel and the luer-lock adapter firmly using your thumb and forefinger.
With the opposite hand, securely attach the needle shield or cannula hub by pushing and twisting until it is firmly locked in place.
Improper assembly may cause the needle or cannula to detach during injection.
Never bend or manipulate the needle or cannula before or during treatment, as this may increase the risk of breakage.
If using the Smart Click System, activate it by pressing the button on the finger grip until it locks into position.
Before injecting, slowly press the syringe plunger until a small droplet of gel appears at the needle tip. This removes trapped air and ensures smooth product delivery.
Injection Technique
Correct injection technique helps achieve optimal aesthetic outcomes.
If using a cannula, first create an entry point with a sharp needle.
Insert the cannula and inject slowly while keeping the opening facing downward, away from the skin surface, to maintain the correct tissue depth.
Restylane should be injected into the mid-dermal layer unless the specific product instructions indicate otherwise.
Avoid applying excessive force during injection.
If resistance is encountered, such as from scar tissue, partially withdraw and reposition the needle or cannula. If necessary, remove it completely to verify proper function before continuing.
Avoid injecting excessive volumes or placing the filler too superficially, as this may result in visible lumps or irregularities.
If blanching (whitening) of the skin occurs, stop the injection immediately and gently massage the area until normal skin color returns.
After the Injection
Once treatment is complete:
Gently massage the treated areas if any irregularities are observed.
Monitor the patient for any immediate adverse reactions.
Dispose of the syringe, needle, cannula, and any unused product according to local medical waste regulations.
Recommended Treatment Schedule
According to the manufacturer, optimal results are often achieved with:
Three initial Restylane treatment sessions spaced 2 to 4 weeks apart.
Maintenance treatments every 4 to 6 months to preserve results.
Individual treatment plans may vary depending on the patient’s anatomy, aesthetic goals, and clinical response.
Possible Side Effects
Patients should be informed that temporary side effects may include:
Mild swelling
Redness
Bruising
Tenderness
Temporary discomfort at the injection site
These reactions are generally mild and resolve within several days. Patients should contact their healthcare provider if they experience severe pain, persistent discoloration, signs of infection, or any unusual symptoms.
Conclusion
Successful Restylane treatment depends on careful patient assessment, proper aseptic technique, correct syringe preparation, and precise injection into the appropriate tissue plane. Adhering to the manufacturer’s recommendations and following safe injection practices helps deliver predictable, natural-looking results while reducing the likelihood of complications.
