LANGEVIAX PROCEDURE GUIDE

Injectables / LANGEVIAX

Choosing a filler begins with the volume or contour concern and the risk you are willing to accept. Material, treatment site and complication management matter more than promotional labels.

Compare the major filler materials

HA fillers are water-binding gels, sometimes cross-linked for greater persistence. CaHA contains mineral particles in a gel carrier; PLLA is a biodegradable polymer with more gradual effects. Both can stimulate a tissue response, but their onset, suitable sites and behaviour differ from HA. PMMA contains persistent particles. Autologous fat requires a separate harvesting and transfer procedure.

HA offers early volume change and, in selected circumstances, clinician-administered hyaluronidase to reduce material. This does not guarantee reversal of vascular injury or every unwanted effect. Longer persistence with CaHA, PLLA or permanent materials can be attractive, but unwanted results may be harder to manage. No material is best for every facial region.

Match the effect to the concern

Filler may improve selected hollows or contours; excess skin, pigmentation and movement lines are different targets. Early swelling can misrepresent size and symmetry. Record the desired change with standardized photographs and a specific goal before treatment. Discuss the point at which adding volume would no longer help and what an acceptable partial improvement would look like.

History that changes the decision

Identify previous fillers or implants and their sites, even years later. Discuss severe allergies, local-anaesthetic reactions, bleeding disorders, cold sores and skin disease or infection. Pregnancy and breastfeeding require review. If earlier material is unknown, photographs alone are insufficient for repeat treatment; the clinician may need additional assessment before deciding whether or where another injection is appropriate.

Questions before committing

Ask for the exact product, material, Canadian licence and indicated treatment site; US approval is not Canadian authorization. Record the injector’s identity, an after-hours contact and the complication-response plan. Disclose medicines without stopping prescribed treatment yourself. Clarify costs for follow-up or managing an unwanted result, and request a copy of the product record for future care.

Separate swelling from the result

Early swelling, tenderness and bruising can occur, while nodules or inflammation may appear later. Set a review date appropriate to the particular material and site. Do not press on a lump or improvise massage: instructions for some materials differ from HA. Tell the clinician about recent infection, dental work and planned procedures when arranging your care.

Supportive care and product choices

If the clinic recommends cooling for routine swelling, ask how to apply it safely without pressure. On intact skin, discuss gentle cleansing, fragrance-free moisturizer and sun protection; creams do not treat a blocked vessel or infection. Makeup and active ingredients over open or irritated sites require individualized advice. Adding several new products can obscure the cause of a reaction.

Immediate warnings and delayed problems

Unusual or increasing pain, white, grey or blue skin, or visual changes after filler require immediate medical care. Call 911 for visual loss, stroke symptoms or breathing difficulty and state that you recently received filler. Nodules, drainage, warmth or increasing redness also need assessment; do not wait for a cream or massage to resolve them.

Frequently asked questions

Is permanent filler better value?

Long persistence does not remove the cost or difficulty of complications. Compare correction options, changing goals with age and long-term follow-up before deciding.

Section sources: FDA — FDA-Approved Dermal Fillers: materials · FDA — Dermal Fillers (Soft Tissue Fillers)

Filler or botulinum toxin?

Filler changes volume or contour; botulinum toxin reduces muscle activity. The cause of a line guides the choice. Combining them is not necessary for everyone.

Section sources: Health Canada — Cosmetic injections

Are lip and under-eye fillers interchangeable?

Product properties, anatomy, risk and authorized uses differ. The HA label alone does not establish suitability or authorization for every site.

Canadian sources take priority for regulatory context. FDA or other foreign information does not establish Canadian authorization for a product or use. A source-check date is distinct from publication date or independent clinical approval.
