Do You Really Know About Hyaluronic Acid (HA) Fillers?

Hyaluronic Acid, abbreviated as HA, is essentially a type of glycosaminoglycan widely found in the dermis layer of our skin and in connective tissues. It is one of the major components of the extracellular matrix.It is a transparent, viscous gel-like substance that can absorb multiple times its own volume in water, thereby having a strong moisturizing function. This keeps the skin hydrated, delicate, soft, and elastic. Single-chain HA molecules are quickly degraded by hyaluronidase in the human body, with a half-life of 1 to 2 days. Due to the short retention time, it cannot achieve long-term filling effects. Therefore, to extend the retention time of HA in the body, the single-chain HA molecules need to be cross-linked to form a block. This cross-linked HA is metabolized more slowly in the body and can last for months or even years, thereby achieving a lasting filling effect.

Functions of Hyaluronic Acid (HA) Filler

Wrinkle Removal

Hyaluronic acid filler can effectively remove static wrinkles on the face, which exist even without any facial expressions. Through filling, these wrinkles can be significantly improved, making the face smoother.

Improving Facial Sagging and Laxity

As we age, various parts of the face, such as the temples, cheeks, eye sockets, and the area around the lips, may show signs of volume deficiency, leading to the disappearance of the apple cheeks and the appearance of nasolabial folds and mouth corner bags. Hyaluronic acid filler can effectively address tissue deficiencies in these areas, making the face fuller and tighter, thereby restoring a youthful appearance and improving facial contours.

Lip Augmentation

With aging, the lips usually shrink and develop wrinkles, and the corners of the mouth may droop. Hyaluronic acid filler can effectively plump the lips, improve lip shape, and restore youthful lip contours.

Nose and Chin Augmentation

For individuals with insufficient volume in the nose or chin, hyaluronic acid filler can be used to enhance the shape of these areas, making them more defined and harmonious.

Filling Depressions

Hyaluronic acid filler can also be used to fill facial depressions caused by acne scars, injuries, surgery, or congenital defects, helping to restore the smoothness and three-dimensional appearance of the skin. Common areas for filling include the temples, nose, apple cheeks, tear troughs, cheeks, jawline, and lips, with HA filler under eye being more commonly used.

Duration

Generally, the effects of hyaluronic acid filler can last for about 0.5 to 1 year. However, it is important to note that the duration varies from person to person and is influenced by factors such as daily care methods, injection sites, expression activities, and the type of HA used.

Advantages of Hyaluronic acid (HA) Filler

No blood tests required with easy operation

Hyaluronic acid fillers typically do not require blood tests, making the procedure simple and quick, allowing you to resume normal activities immediately after the injection.

Quick treatment process

The treatment process for hyaluronic acid filler is relatively fast, usually taking between just a few minutes to 15 minutes.

Short recovery time

The recovery period for hyaluronic acid filler is relatively short, usually allowing you to return to normal activities within a short time.

Injection Methods for Hyaluronic acid (HA) Filler

During the HA filling process, the injection is usually performed in a semi-reclining position. This position closely mimics the natural state during social interactions, helping doctors assess the injection site for ideal results and allowing the patient to relax and receive the injection calmly. Other positional changes that could lead to displacement and affect the filling effect should be avoided. In some cases, a supine position may also be used for HA filler under eye. Patients should follow the doctor's instructions to adjust their position and direction to ensure the best injection outcome.
