What the evidence says
Filler is a medical injection. The appropriate product, amount and anatomical plane depend on the treatment area and examination; not every filler is intended for every location.
Hyaluronic acid dermal filler
Hyaluronic-acid filler restores volume and refines contour — cheeks, chin, lips, tear trough and more — with natural, reversible results.

Quick answer
Hyaluronic-acid filler can replace selected volume or support facial structure. It is a medical injection rather than a general skin-quality treatment, so the plan must consider anatomy, product choice, reversibility and the rare but urgent risk of vascular occlusion.
Hori uses hyaluronic acid (HA) fillers — HA is a sugar molecule the skin already makes that can hold many times its weight in water. Cross-linked into a smooth gel of varying firmness, it is placed in precise planes to restore lost volume, support structure and smooth folds.
Different products are chosen for different jobs: a soft, flexible gel for lips and fine lines; a firmer, more cohesive gel to rebuild cheek or chin structure. Results are immediate, settle over a week or two, and — importantly — can be dissolved with an enzyme (hyaluronidase) if an adjustment is ever wanted.
HA gel adds immediate volume and structure where it is placed.
HA binds water, helping skin look hydrated and plump.
It is gradually broken down by the body and can be dissolved with an enzyme if desired.
After assessing facial proportions, the doctor injects hyaluronic-acid gel with a needle or cannula, often using a numbing cream or HA pre-mixed with anaesthetic for comfort. A session takes about 30 minutes.
Mild swelling or small bruises may occur and settle within days. Avoid heat, intense exercise and pressure on the area for 24–48 hours. Results are visible immediately and refine as swelling resolves.
Results are immediate and typically last 6–18 months depending on the product and area. Because HA filler can be dissolved with an enzyme, the result is adjustable and reversible.
Everyone responds differently. Before treatment, your doctor will examine the area and talk through a plan that makes sense for you.
No filler injection is risk-free. Product choice, anatomy and technique matter; rare intravascular injection can cause tissue injury, visual complications or stroke. The doctor should explain product- and area-specific risks before consent.
Hyaluronidase can break down many HA fillers, but it is a medical treatment with its own risks and may not completely reverse every complication or aesthetic result.
The aim can be a subtle, balanced change, but the visible outcome varies with anatomy, product, swelling and technique and cannot be guaranteed.

Swelling and bruising are common. Rare intravascular injection can cause tissue injury, visual complications or stroke; unusual pain, vision change or pale/blue skin needs urgent assessment.
Regulatory references describe their own jurisdictions and are used for safety context; they do not by themselves establish Thai registration or an indication for a specific product.
