Before choosing a treatment

Hyaluronic acid fillers

Before adding volume, consider balance and safety

Hyaluronic acid

What do dermal fillers do?

Fillers place material beneath the skin to supplement volume or contour. This guide focuses on HA fillers. Authorized sites and purposes differ by product.

Define the goal before the amount.

Discuss your goals from the front, side and in expression. Report any previous injections, their products, sites and dates. Ask separately about brand, amount, sites and total fees.

Official product information ↗

Hollowness and sagging may need different approaches.

Adding volume does not address every case of sagging or asymmetry. Discuss alternatives, including no procedure, and realistic expectations.

What to discuss

Your goals and current condition

Describe your concern, goals and important dates. Bring your treatment history so the clinician can assess suitability and alternatives.

Health and allergies

Disclose medicines, bleeding conditions, ingredient or anesthetic allergies, pregnancy or breastfeeding, and local inflammation or infection. Do not stop prescribed medicines on your own.

Product and follow-up contact

Confirm the exact product, expiry, sites and costs. Before treatment, obtain contact details and instructions for concerns at night or on holidays.

Process and recovery planning

01
Assessment and goals
Review skin and medical history; discuss expected changes, limits and alternatives.
02
Product check and consent
Decide after understanding ingredients, sites, pain management, risks and costs.
03
Procedure and assessment
The clinician follows the agreed plan and checks your condition afterward.
04
Aftercare and follow-up
Obtain product-specific guidance on washing, makeup, exercise, alcohol and massage. Do not rub the area or arrange additional treatment without checking with your clinician.

There is no universal duration, session count or longevity. Confirm an individual plan based on the product, area and condition.

Reactions to watch

Injection procedures can cause swelling, bruising, redness and pain. Lumps, nodules, infection or allergic reactions may need assessment. Contact the treating clinic if symptoms persist or worsen.

Follow the exact product instructions. This is not a complete list of risks or contraindications.

Common questions

Can HA fillers always be fully reversed?

Removal or reduction may require treatment with its own risks and limits. Being potentially dissolvable does not make a procedure risk-free.

Will one session work the same for everyone?

No. Response and further treatment depend on the product, site, skin and goals. Ask how progress will be assessed rather than relying on a fixed-session promise.
