Biostimulator Injections vs. Fillers — Which Should You Choose?

What are Biostimulator Injections?

Biostimulator injections, also known as biostimulatory fillers, are a type of injectable treatment that stimulates the body’s natural collagen production. Unlike traditional fillers that provide immediate volume, biostimulators work overtime to rejuvenate the skin from within. 

Common biostimulatory substances include poly-L-lactic acid (PLLA) and calcium hydroxylapatite (CaHA).

How Biostimulators Work?

Biostimulators for face work by triggering the body’s natural healing response, which promote collagen and elastin production. This process gradually improves skin texture, firmness, and elasticity. 

The results of a biostimulation facial develop over several months, leading to a more youthful and natural-looking appearance.

What are the Benefits of Biostimulators Facial?

  • Long-Lasting Results: Since biostimulators stimulate collagen production, the results can last up to two or more years.
  • Natural Appearance: The gradual improvement in skin quality ensures a natural look.
  • Comprehensive Rejuvenation: Biostimulators improve skin texture, tone, and elasticity, addressing multiple signs of aging.
  • Versatile Treatment for Various Areas: This treatment can be used to multiple areas of the face and body, including the cheeks, temples, lower cheeks, jawline, neck, and chest.

Biostimulator Injections: Before and After

The transformation with biostimulator injections can be impressive but requires patience. Initially, you may not see significant changes, but the skin’s texture and firmness gradually improve over the following months. 

Over time, the treated areas show noticeable improvements. Wrinkles and fine lines are minimized, and the skin appears firmer. The overall quality of the skin improves, giving it a more youthful and refreshed appearance.

What are Dermal Fillers?

Dermal fillers are injectable treatments which are designed to add volume while reducing wrinkles and fine lines. They typically consist of hyaluronic acid (HA), a naturally occurring substance in the skin. 

Dermal fillers provide immediate results, making them a popular choice for quick rejuvenation.

How Dermal Fillers Work?

Fillers function by adding volume to the targeted areas, like the cheeks, lips, and nasolabial folds. They also fill in wrinkles and hollow areas, providing an instant plumping effect. 

HA fillers also attract water, which helps to maintain skin hydration and elasticity.

What are the Benefits of Dermal Fillers?

  • Natural Appearance: Provides a natural look by smoothing wrinkles and restoring volume.
  • Immediate Results: Fillers offer quick improvements in facial volume and wrinkle reduction.
  • Versatility: They can be used in various areas of the face for contouring and enhancement.
  • Minimal Downtime: Most filler treatments require minimal to no downtime, faciliating a quick return to daily activities.

Dermal Fillers: Before and After

Initially, you will see an immediate improvement in facial volume and contour. Over the next few days, the full effect becomes more apparent as any minor swelling subsides.

The treated areas appear plumper, smoother, and more youthful. Fine lines and wrinkles are diminished, facial contours are enhanced, and skin texture looks healthier and more hydrated.
