Dermal fillers are injectable materials we use to restore facial volume, smooth lines, and refine facial contours. In brief, the main categories are hyaluronic acid, calcium hydroxylapatite, poly L lactic acid, polymethylmethacrylate microspheres, and autologous fat transfer. Each option has different uses, longevity, and tradeoffs, and we choose a plan based on anatomy, goals, and medical history.

What are dermal fillers

Dermal fillers are soft tissue injectables placed beneath the skin to add volume, lift superficial depressions, and soften creases. They are not the same as neuromodulators, which temporarily reduce muscle movement. Fillers can treat areas such as the cheeks, lips, nasolabial folds, marionette lines, tear troughs, chin, jawline and temples.

We use fillers as part of cosmetic dermatology when the goal is structural support, contouring, or replacement of lost fat and collagen. The choice of material depends on how much lift is needed, how long the result should last, reversibility, and the risk profile for the patient.

Why dermal filler options matter in Newburgh and the Hudson Valley

Local access to an experienced dermatologist matters because facial anatomy varies by age, ethnic background, and prior procedures. As a Newburgh practice led by Henry A Greenblatt, MD, we combine medical evaluation with cosmetic goals so patients from the Hudson Valley get care tailored to their needs without traveling far.

Choosing the right filler minimizes complications such as lumps, migration, or unwanted contour changes. It also affects follow up planning, touch up frequency, and how fillers interact with other treatments such as laser resurfacing or scar revision.

Key concepts at a glance

  • Hyaluronic acid, or HA. A water attracting gel used for smoothing lines and adding volume. It is reversible with an enzyme if needed.
  • Calcium hydroxylapatite, or CaHA. A thicker, more supportive filler used for deeper volume and structural lift.
  • Poly L lactic acid, or PLLA. A biostimulatory product that works by stimulating gradual collagen production over months.
  • Polymethylmethacrylate, or PMMA. A semi permanent option composed of microspheres in a collagen carrier used for long term correction in select cases.
  • Autologous fat transfer. Fat is harvested and reinjected for natural long term volume, typically performed in conjunction with minor surgical procedures.
  • Reversibility and longevity. HA is reversible and typically lasts months to over a year. Biostimulatory and permanent options last longer but require careful patient selection.

How we evaluate which filler is right for you

We consider medical history, prior procedures, facial anatomy, skin quality, and realistic goals. Our assessment focuses on volume loss patterns, skeletal support, and where movement contributes to lines. For example, thin tear trough skin needs a different approach than deep cheek hollowing.

Elements of our assessment

  • Discussion of cosmetic goals and expectations
  • Review of medical history and medications that affect bleeding and healing
  • Examination of facial anatomy and skin tone
  • Photographic documentation to track results
  • Review of prior injectable products or surgeries

When a biostimulatory or longer acting product may be appropriate, we explain the timeline, expected gradual changes, and how many sessions could be required to achieve the desired look.

Common questions people ask about fillers

Who is a good candidate

Adults seeking improvement in facial volume, contour, or softening of lines are typical candidates. Active infection at the injection site, certain autoimmune conditions, or pregnancy are reasons to delay treatment. We review these during the medical history.

Are fillers safe

When placed by a clinician with detailed facial anatomy knowledge, fillers have a strong safety record. Risks include temporary bruising, swelling, asymmetry, and rarely vascular occlusion. We discuss risk factors and immediate measures in the unlikely event of a complication. The United States Food and Drug Administration provides guidance on approved injectable products and safety considerations at a federal level, which we follow.

How long before I see results

Hyaluronic acid and CaHA typically show immediate improvement with some settling over two weeks. PLLA works gradually over several months as new collagen forms. Fat grafting may require a healing period and variable survival of transferred fat.

What to expect during treatment and aftercare

We provide a clear plan during the consultation. Typical in office elements include marking the treatment areas, discussing numbing options, and controlled injection technique. We do not publish step by step injection protocols because those require professional training and individual judgment.

High level aftercare points we emphasize are:

  • Avoid strenuous exercise and excessive heat for a short period after treatment
  • Expect mild swelling and bruising that typically resolves in days to a week
  • Report severe pain, changes in skin color, or spreading numbness immediately for urgent assessment

Pro tip: Bring photos of the outcome you hope to achieve and also of your natural relaxed face. That helps us match treatment to your aesthetic goals and avoid overcorrection.

Checklist for choosing a filler approach

Before you decide

  • Confirm the injector is a qualified physician with facial anatomy experience
  • Ask which product class will be used and why it fits your goals
  • Understand the expected timeline and how many sessions are likely
  • Review common side effects and the clinic plan for managing complications
  • Ensure the plan fits any upcoming procedures such as lasers or surgery

Key takeaway

Different fillers serve different goals. Hyaluronic acid is versatile and reversible. Biostimulatory products are chosen for gradual long lasting volume. Permanent options and fat transfer can be appropriate for select patients, but they require careful selection. We tailor the choice to anatomy, goals and safety considerations at our Newburgh dermatology practice.

Frequently asked questions

How long do dermal fillers last

Longevity varies by product and treated area. Hyaluronic acid fillers often last from six months to over a year. Calcium hydroxylapatite and poly L lactic acid tend to last longer. Fat grafting and PMMA provide longer term results but have different risk and maintenance profiles.

Can filler be dissolved if I do not like the result

Hyaluronic acid fillers can be dissolved with hyaluronidase. Other filler types are not reversible and require different management strategies, so product selection is an important part of the initial consultation.

Are there side effects I should expect

Common short term effects include swelling, bruising, and tenderness. Rare but serious complications include vascular compromise and infection. We review risks and the signs that require prompt evaluation at every consultation.

Can fillers be combined with other treatments

Yes, fillers are often combined with neuromodulators, lasers, or scar revision. Timing matters. We coordinate treatment sequencing to minimize risk and optimize results.

How do you decide between fillers and fat transfer

We consider the amount of volume needed, the desire for a natural tissue option, prior surgeries, and overall health. Fat transfer is a surgical option that can provide durable volume but involves a harvesting step and variable fat retention.

Is everyone a candidate for fillers

Not everyone. Active infection, certain autoimmune diseases, and pregnancy are common reasons to defer. We review medical history and expectations to determine candidacy.
