Dermal Fillers: What Happens to Your Face as the Treatment Takes Effect?

What Are Dermal Fillers?

Dermal fillers are injectable products used beneath the skin to restore volume, improve contours and soften the appearance of certain lines and folds.

Depending on the product, they may be used to:

• Restore volume lost with aging.
• Enhance the lips.
• Define the cheeks.
• Improve chin projection.
• Contour the jawline.
• Improve selected facial asymmetries.
• Smooth certain facial lines.

Many commonly used fillers are based on hyaluronic acid, although other materials are also available.

What Are Biostimulators?

Biostimulators are injectable products designed to stimulate a biological response in the skin and underlying tissues.

Rather than relying only on immediately adding volume, some biostimulatory treatments encourage collagen production and gradual tissue remodeling.

Sculptra and Radiesse are examples of injectable products used for biostimulatory treatment, although their materials, mechanisms and approved indications differ.

Hyaluronic Acid Fillers

Hyaluronic acid (HA) is a substance naturally found in the body.

HA fillers can be used to:

• Add volume to the lips.
• Enhance cheek volume.
• Improve chin definition.
• Contour the jawline.
• Restore volume loss.
• Improve selected facial lines and folds.

One advantage of many HA fillers is that some formulations can be reversed with hyaluronidase when medically appropriate.

The duration of the effect varies by product, area treated and individual factors.

Sculptra

Sculptra contains poly-L-lactic acid (PLLA) and is a collagen-stimulating injectable.

Rather than producing its full effect immediately, Sculptra is intended to stimulate the body's collagen response gradually.

It may be used to improve:

• Facial volume loss.
• Overall facial contours.
• Certain signs of aging associated with reduced tissue volume.

Treatment usually involves a series of sessions rather than relying on a single immediate-volume injection.

The exact technique and indications should be determined by a qualified medical professional.

Radiesse

Radiesse contains calcium hydroxylapatite (CaHA) microspheres in a gel carrier.

It can provide immediate structural support while also producing a biostimulatory effect that contributes to collagen and elastin production.

Depending on the formulation and indication, Radiesse may be used for:

• Facial contouring.
• Volume correction.
• Improvement of selected signs of skin aging.
• Certain hand rejuvenation treatments.

The product and injection technique should be selected according to the specific treatment goal and approved indications.

What Can These Treatments Improve?

Dermal fillers and biostimulators may be used to address:

Volume Loss

They can restore volume that has decreased with age or weight changes.

Cheeks

Treatments may enhance cheek definition and restore mid-face volume.

Lips

HA fillers are commonly used to increase lip volume and definition.

Chin and Jawline

Selected fillers can improve projection and contour.

Facial Lines and Folds

Some fillers can soften certain lines and folds associated with volume loss.

Skin Quality

Biostimulatory treatments may support gradual improvement in skin firmness and overall quality through collagen remodeling.

Who Is a Good Candidate?

Injectable treatments may be appropriate for adults who:

• Want to improve facial volume or contours.
• Have realistic expectations.
• Prefer a minimally invasive treatment.
• Are generally healthy.
• Understand that results vary between products and individuals.

A medical consultation is essential to determine the appropriate product, treatment area and technique.

How Is Treatment Performed?

A typical treatment includes:

1.      Assessment of facial anatomy and skin quality.

2.      Discussion of goals and expected outcomes.

3.      Selection of the appropriate product.

4.      Cleansing and preparation of the treatment area.

5.      Application of topical or local anesthesia when appropriate.

6.      Precise injection of the selected product.

7.      Assessment of symmetry and contours.

8.      Post-treatment instructions.

The number of injections and amount of product depend on the patient's anatomy and treatment goals.

Preparation Before Treatment

The medical professional may review:

• Medical history.
• Current medications and supplements.
• Allergies.
• Previous cosmetic injections.
• Previous reactions to fillers.
• Skin infections or inflammation.
• Pregnancy or breastfeeding when relevant.

Patients should provide complete information about medications and medical conditions before treatment.

Recovery and Aftercare

Most filler and biostimulator treatments involve minimal downtime.

Temporary effects may include:

• Swelling.
• Bruising.
• Redness.
• Tenderness.
• Mild discomfort.
• Temporary asymmetry.

After treatment, patients may be advised to avoid excessive pressure on treated areas and to follow specific recommendations regarding exercise, heat exposure and skincare.

Aftercare varies according to the product and injection technique.

When Will Results Be Visible?

The timing depends on the product.

Hyaluronic Acid Fillers

Results are generally visible immediately, although swelling may temporarily change the appearance.

Radiesse

Some immediate improvement can occur because the gel provides initial volume, while the biostimulatory effects develop gradually.

Sculptra

Results develop progressively as collagen production increases and may require a series of treatment sessions.

The final appearance varies between patients.

How Long Do Results Last?

The duration depends on:

• Product type.
• Treatment area.
• Amount used.
• Individual metabolism.
• Lifestyle.
• Number of treatment sessions.

HA fillers provide temporary results, with longevity varying by formulation and location.

Biostimulatory treatments may produce longer-lasting changes as new collagen develops, but the effects are not permanent and maintenance may eventually be needed.

Possible Risks and Complications

Common temporary effects include:

• Swelling.
• Bruising.
• Redness.
• Tenderness.
• Itching.
• Temporary lumps or unevenness.

Potential complications can include:

• Infection.
• Inflammatory reactions.
• Nodules or granulomas with certain products.
• Asymmetry.
• Vascular occlusion.

Vascular occlusion is a rare but potentially serious complication of injectable fillers and can result in tissue damage or, in rare cases, vision loss.

Some biostimulatory products also have specific risks related to the material and injection technique.

For this reason, treatment should be performed by an appropriately qualified medical professional with knowledge of facial anatomy and management of injectable complications.

Dermal Fillers vs. Biostimulators

The choice between fillers and biostimulators depends on the desired outcome and individual anatomy.
