What are Hyaluronic Acid Fillers ?

Hyaluronic acid (HA) fillers are a type of cosmetic injection used to reduce wrinkles, add volume to areas of the face, and enhance facial contours. HA fillers are typically synthesized from bacteria or produced through biotechnology. They are typically soft and gel-like. The effects of hyaluronic acid fillers are temporary, lasting 6 to 12 months or longer before the body gradually and naturally absorbs the particles.

There are several types of hyaluronic acid fillers used for cosmetic injections, each designed to address specific concerns and achieve different aesthetic outcomes. Some of the common FDA-approved HA fillers include:

  • Revanesse: Revanesse HA fillers are designed to provide natural-looking results and are used for facial contouring, lip augmentation, and smoothing moderate to severe wrinkles and folds.

Indications of Hyaluronic Acid Fillers ?

Hyaluronic acid fillers are commonly used to address signs of aging, such as fine lines, wrinkles, and loss of volume in the face. They can also be used for lip augmentation, cheek enhancement, and reshaping facial features.

How Do Hyaluronic Acid Fillers Work?

Hyaluronic acid is a naturally occurring substance in the body that helps maintain moisture and elasticity in the skin. As we age, the production of HA in the skin decreases, leading to a loss of volume, elasticity, and hydration. This process contributes to the formation of wrinkles, fine lines, and sagging skin. The injected HA filler adds volume to the targeted areas, effectively filling in wrinkles, creases, and hollow areas. This can result in smoother skin, reduced lines, and a more youthful appearance.

Preparation for Hyaluronic Acid Fillers

Preparation for hyaluronic acid fillers may involve the following steps:

  • A review of your medical history, allergies, and the medications or supplements you are taking.
  • You may be asked to avoid medications and supplements that can thin the blood, such as aspirin and vitamin E as these substances can increase the risk of bruising and bleeding at the injection sites.
  • You are advised to refrain from smoking or alcohol as these can affect the healing process and increase the risk of complications.
  • A signed informed consent will be obtained from you after explaining the procedure, potential risks, and expected outcomes.

Procedure for Hyaluronic Acid Fillers

Before the procedure, the treatment area is cleansed, and a topical numbing cream may be applied to minimize the discomfort of the injections. Once the skin is numb, the healthcare provider carefully injects the HA filler into specific areas of the face using a fine needle or cannula. They may use a series of injections to achieve the desired results, targeting wrinkles, folds, or areas that require volume enhancement (e.g., lips, cheeks, chin). After injecting the filler, the provider may gently massage the treated areas to ensure even distribution and smooth out any lumps or irregularities. They will evaluate the results to determine if additional filler is needed or if any adjustments are required.

Post-Procedure Care Instructions

After the injections, you may experience temporary swelling, redness, or bruising at the injection sites. Cold packs or ice packs may be applied to reduce swelling. Your provider will provide post-procedure care instructions, including skincare recommendations and activities to avoid. Stay well-hydrated and maintain a healthy diet before and after the procedure. Proper hydration supports skin health and can contribute to optimal healing. Follow-up appointments may be scheduled to monitor your progress, address any concerns, and assess the longevity of the results.
