Dermal Fillers

Dermal fillers are injectable gels, most commonly composed of hyaluronic acid (HA) or other safe, biocompatible materials, that add volume and smoothness beneath the skin. They fill in wrinkles, restore lost volume, and enhance facial contours, giving you a rejuvenated, more youthful appearance. 

Dermal fillers can address a wide range of aesthetic concerns, including:

• Loss of volume in cheeks, temples or under-eyes
• Nasolabial folds (smile lines) or marionette lines
• Lip filler for thin or asymmetrical lips
• Sunken cheeks / hollow facial areas
• Chin contouring and jawline definition
• Softening scars or improving facial symmetry

The injection session usually takes about 30–60 minutes. Most fillers include lidocaine or use a numbing cream, so discomfort is minimal. After treatment, you can typically return to daily activities immediately (or after a short rest). Mild swelling or redness may occur, but serious downtime is rare. 

Results: Usually clients see immediate improvement. For some fillers (especially ones that stimulate collagen, such as HarmonyCA), full effects will be observable in a few months.

Duration: Depending on the type of filler, treatment area, and individual factors, results typically last between 6-18 months. Some fillers may last up to 2 years or more.

Most clients describe filler injections as comfortable or only mildly uncomfortable. With numbing (topical or via lidocaine in the filler), any discomfort is minimal. 

Common short-term side effects may include: redness, swelling, bruising, tenderness, or slight lumpiness at injection sites. These usually subside within a few days to a week. 

Less common but more serious risks, especially if filler is injected improperly or by unqualified personnel, may include infection, vascular occlusion (if filler accidentally enters a blood vessel), nodules or lumps under the skin, skin discoloration, or asymmetry. 

That’s why it’s very important to choose a reputable aesthetic clinic and experienced injector, like The Metro Clinic.

Yes, when properly administered by a skilled, experienced injector, fillers enhance your natural features subtly without giving an “over-filled” or “fake” look. The key is a conservative, individualized approach tailored to your facial anatomy. Our goal is always for you to look rested and refreshed, not “overdone.”

Because fillers are gradually absorbed by the body, you’ll need maintenance treatments every 6-18 months, depending on the type of filler used and the treated area. During your consultation at The Metro Clinic, our doctors will recommend an ideal maintenance schedule based on your individual needs. 

Dermal fillers are generally safe for healthy adults, but not everyone is a suitable candidate. You should avoid fillers if you have:

• Certain medical conditions (such as blood disorders, active infections at the injection site)
• Known allergy to filler components
• Unrealistic expectations.

A full medical consultation and assessment help ensure safe, effective treatment.

Before treatment: 

Avoid anti-inflammatory medications (if medically allowed), alcohol, and certain supplements 24–48 hours before injection to reduce bruising risk.

Arrive with clean skin, no makeup.

After treatment:

• Avoid pressing or massaging treated areas for at least 4–6 hours.
• Avoid heavy exercise for the next 24 hours, saunas, extreme heat or intense skincare for 2 weeks.
• Drink plenty of water and follow after-care instructions given by your injector.

These simple steps help minimize risk and ensure optimal, natural-looking results.
