Restylane® is one of the most established families of hyaluronic acid (HA) dermal fillers used in aesthetic medicine. The portfolio includes multiple formulations designed for different treatment areas and aesthetic objectives, ranging from facial wrinkles and folds to lip enhancement, cheek augmentation, chin contouring, and under-eye hollowing.
For aesthetic professionals, understanding the differences between Restylane products is essential. Restylane is not a single universal filler; individual formulations differ in gel technology, firmness, flexibility, approved indications, injection characteristics, and expected duration.
This professional guide explains how Restylane works, reviews the major technologies and product families, and outlines important considerations for product selection, patient counseling, treatment expectations, and professional procurement.
What Is Restylane?
Restylane is a family of injectable dermal fillers manufactured by Galderma. The products are made with stabilized hyaluronic acid, a naturally occurring substance found throughout connective tissue.
Hyaluronic acid attracts and binds water, helping support tissue hydration and volume. In dermal fillers, manufactured HA is stabilized and cross-linked to create an injectable gel that persists in tissue longer than naturally occurring, unmodified HA.
Depending on the specific Restylane formulation and applicable labeling, products may be used for treatment objectives involving:
- Moderate to severe facial wrinkles and folds
- Lip augmentation and lip lines
- Cheek augmentation
- Chin augmentation
- Under-eye hollowing
- Midface contouring
- Selected hand volume loss
Practitioners can also browse professional dermal fillers available through Health Supplies Plus.
How Does Restylane Work?
Restylane fillers temporarily add HA gel volume to selected facial tissues. The physical gel can support tissue, soften selected wrinkles and folds, restore contour, or enhance facial features according to the product being used.
The result is generally visible immediately after injection because the product physically occupies space within the treatment area. However, swelling, bruising, tenderness, and other temporary injection-site reactions can affect the early appearance.
Over time, the HA gel is gradually broken down and absorbed by the body.
It is more accurate to describe Restylane as providing temporary HA-based structural support and volume rather than claiming that every Restylane product substantially stimulates new collagen production.
Restylane Technologies: NASHA vs. XpresHAn
Galderma uses two principal HA gel technologies within the Restylane portfolio: NASHA® Technology and XpresHAn Technology™, also known as OBT™ in some markets.
NASHA Technology
NASHA stands for Non-Animal Stabilized Hyaluronic Acid. Galderma describes NASHA products as having a firmer gel texture designed for precision, structure, targeted projection, and lift.
Current NASHA products include formulations such as:
- Restylane / Restylane-L
- Restylane Lyft
- Restylane Silk
- Restylane Eyelight
XpresHAn Technology
XpresHAn products are designed with greater flexibility to support facial movement and expression.
Current formulations using XpresHAn Technology include:
- Restylane Kysse
- Restylane Refyne
- Restylane Defyne
- Restylane Contour
The existence of these two technologies allows practitioners to select different gel characteristics depending on the anatomy and treatment objective.
Popular Restylane Products and Their Uses
Restylane / Restylane-L
Restylane 1 mL with Lidocaine is one of the classic formulations in the portfolio and uses NASHA technology.
It is used for correction of moderate to severe facial wrinkles and folds, including nasolabial folds, and for lip augmentation according to applicable labeling.
Restylane Lyft
Restylane Lyft is a firmer NASHA filler designed for structural support and deeper correction.
Depending on current labeling, applications can include cheek augmentation, facial wrinkles and folds, selected chin augmentation, and correction of age-related volume loss in the backs of the hands.
Restylane Kysse
Restylane Kysse uses XpresHAn Technology and is formulated specifically for the dynamic lip region.
It is indicated for lip augmentation and correction of upper perioral lines in appropriate adult patients.
Restylane Refyne
Restylane Refyne uses XpresHAn Technology to provide flexible support in dynamic facial areas.
It is used for moderate facial wrinkles and folds, including nasolabial folds and marionette lines.
Restylane Defyne
Restylane Defyne is designed for deeper wrinkles and folds and also has selected chin applications.
Its XpresHAn formulation is intended to provide structural support while maintaining flexibility during facial movement.
Restylane Contour
Restylane Contour is an XpresHAn filler developed specifically for cheek augmentation and correction of midface contour deficiencies.
Restylane Eyelight
Restylane Eyelight is a NASHA filler designed specifically for improvement of under-eye hollowing.
Because the infraorbital region is anatomically delicate and prone to swelling, product selection and practitioner training are especially important.
How Long Does Restylane Last?
There is no single duration that applies to all Restylane products.
According to current Galderma clinical information, approximate product-specific durations include:
- Restylane / Restylane-L: improvement in facial wrinkles and folds can persist up to 18 months in clinical studies involving retreatment
- Restylane Kysse: up to approximately 1 year in the lips
- Restylane Refyne: up to approximately 1 year for facial wrinkles and folds
- Restylane Defyne: up to approximately 1 year for facial wrinkles, folds, and selected chin treatment
- Restylane Lyft: up to approximately 1 year in the cheeks and approximately 6 months in facial wrinkles and folds
- Restylane Contour: up to approximately 18 months in the cheeks
- Restylane Eyelight: up to approximately 18 months with optimal treatment
Individual duration depends on the product, treatment area, volume administered, patient metabolism, anatomy, technique, and other clinical factors.
What Happens During a Restylane Treatment?
Treatment begins with a patient assessment and consultation.
The practitioner should review:
- Medical history
- Previous aesthetic treatments
- Current medications and supplements
- Allergies and hypersensitivities
- Patient anatomy
- Aesthetic concerns and expectations
- The specific Restylane product being considered
The quantity of filler used should be determined individually rather than assuming that every treatment requires one or two syringes.
Injection technique, depth, product placement, and instrument choice should follow practitioner training, patient anatomy, and the manufacturer’s current instructions for use.
How Long Does a Restylane Procedure Take?
Treatment time varies according to the area being treated, product, number of injection sites, assessment, preparation, and technique.
Some Restylane procedures may take approximately 15 to 30 minutes for the injection portion, while more extensive treatment plans can take longer.
It is better to describe Restylane as a minimally invasive outpatient treatment rather than promise that every procedure can be completed during a lunch break.
Is There Downtime After Restylane?
Restylane does not require the surgical recovery associated with a facelift or other invasive operation, but patients should not be promised “no downtime.”
Temporary injection-site reactions may include:
- Swelling
- Bruising
- Redness
- Pain
- Tenderness
- Itching
- Firmness
- Temporary lumps or bumps
The extent and duration of these effects varies by patient and treatment area.
Patients should receive product-specific aftercare instructions and understand that their appearance immediately after injection may differ from the final result once swelling has subsided.
When Are Restylane Results Visible?
Because Restylane physically adds HA gel to the treatment area, an initial change in volume or contour is generally visible immediately after treatment.
However, temporary swelling and other injection-site reactions can affect the early appearance.
The result should therefore be reassessed after the acute post-treatment response has settled.
Rather than telling patients that Restylane will continue progressively improving the skin for four months, practitioners should use product-specific clinical data and clearly distinguish immediate filler effects from later retreatment or maintenance results.
Is Restylane Reversible?
Restylane products are hyaluronic acid fillers. Hyaluronidase, an enzyme that breaks down HA, may be used to reduce injected filler when clinically appropriate.
This can be relevant in certain aesthetic corrections and in management of some HA filler complications.
However, hyaluronidase should not be presented as a guaranteed or exact reversal procedure. Response varies according to the product and clinical circumstances.
What Are the Risks of Restylane?
In addition to temporary injection-site reactions, less common complications can include infection, inflammatory reactions, hypersensitivity, persistent nodules, and other adverse events.
One of the most serious potential complications of any facial dermal filler injection is unintended injection into a blood vessel.
Vascular occlusion can interfere with tissue blood supply and may result in tissue injury or necrosis. Rare severe complications associated with filler injections can also include visual impairment, blindness, or stroke.
For this reason, Restylane should be administered only by appropriately trained professionals with detailed knowledge of anatomy, injection techniques, complication recognition, and emergency management.
Who May Not Be an Appropriate Candidate for Restylane?
Contraindications and precautions vary according to the specific Restylane formulation.
Treatment may need to be postponed or avoided in patients with issues such as:
- Active infection or inflammation in the intended treatment area
- Relevant severe allergies or hypersensitivity
- Bleeding disorders or medication-related bleeding concerns
- Other contraindications listed in the specific product labeling
Pregnancy and breastfeeding considerations should also be reviewed according to current manufacturer guidance.
Patient selection should always be based on the specific filler rather than a generic Restylane checklist.

Why the Restylane Portfolio Matters for Aesthetic Practices
The strength of the Restylane family lies in its range of formulations rather than one universal filler.
Practices can select firmer NASHA products when precision and structural support are priorities and more flexible XpresHAn formulations when movement and dynamic facial areas are important considerations.
This makes Restylane useful for clinics that want multiple HA filler options while working within an established product family.
