Dermal fillers are specialized treatments designed to enhance facial appearance by smoothing out wrinkles, softening deep lines, augmenting cheeks, and refining overall facial contours. These fillers come in several types, each with unique properties and applications.

Let’s explore these in more detail:


Fat Injections

This method involves transferring fat from one part of the patient’s body (like thighs, buttocks, or abdomen) to areas of the face that have lost volume. It’s aimed at restoring fullness, smoothing out wrinkles, and correcting hollow areas. The procedure uses a blunt cannula to inject fat into target facial areas, where it integrates with existing tissues and develops its own blood supply. The success of fat grafting varies among individuals and requires careful handling to ensure the transferred tissue thrives. Once successful, fat grafts can provide long-lasting results, often making them a preferred choice over synthetic fillers.

Collagen Injections

Collagen, a protein that forms the supportive structure in the second layer of the skin, is used to diminish aging signs, add facial volume, and repair scars. Derived from either human or animal sources, collagen injections temporarily restore skin’s youthfulness, with effects lasting up to four months.

Hyaluronic Acid (HA)

Found naturally in the body, HA is a key component of over 30 different dermal fillers. It acts like a sponge, absorbing water and bringing moisture to the skin’s surface, making it appear more vibrant and youthful. Besides hydrating the skin, HA supports facial tissues that have lost elasticity or volume. The rejuvenating effects of HA fillers typically last between six to nine months.

Calcium Hydroxylapatite

This filler is used for correcting moderate to severe wrinkles and enhancing facial volume, especially in the cheeks and other facial contours. Composed of calcium particles in a gel, it not only offers immediate improvement but also encourages natural collagen production, extending the durability of its effects to about 12 months.

Poly-L-lactic Acid (PLLA)

PLLA is a synthetic, absorbable material used in dissolvable stitches and to counter deep facial lines caused by collagen loss. Injected into the dermis, it stimulates collagen production, gradually restoring the skin’s structure and volume. Treatment involves multiple sessions, and the semi-permanent results can last around two years.

Polymethyl Methacrylate (PMMA)

PMMA fillers consist of microspheres that provide structural support to the skin. Alongside collagen, PMMA creates a firming effect and encourages the body to produce new collagen, securing the microspheres in place. These fillers are particularly useful for medium to deep wrinkles, lip augmentation, and filling pitted scars, offering semi-permanent improvements.

Each type of dermal filler offers unique benefits, from temporary to long-lasting solutions, catering to various aesthetic needs and preferences.
