Hyaluronic acid

Hyaluronic-acid fillers can be considered for selected volume and contour concerns. Placement follows the anatomy, proportions and a discussion of the change you are looking for.

Your care, step by step.

  1. Assess balance

    Consider proportions, existing volume and previous treatments.

  2. Choose & place

    Agree the product and areas, then perform the planned treatment.

  3. Settle & care

    Follow aftercare and know which symptoms need prompt contact.

  4. Reassess

    Review once the initial tissue response has settled.

What to plan for

Swelling can affect the early appearance. Product choice, injection risks, aftercare and the review interval are discussed before deciding; this is not a fixed full-face package.

The sequence, session count and intervals are agreed individually. This is a pathway, not a fixed calendar.

An informed choice.

What the evidence can tell you — and where its limits matter.

Evidence & expectations

Hyaluronic-acid fillers add volume in selected tissue planes. They can address particular contour concerns, but are not a treatment for every wrinkle or for skin disease. Results and duration depend on the actual product and site.[1]

Preparation & recovery

Discuss previous fillers, allergies, infections and medicines before deciding. Early swelling can obscure the eventual contour. Ask when to review the settled result and which contact to use if a problem appears. Do not change prescribed medicines yourself.[2]

Risks & limitations

Besides bruising, swelling, infection and delayed nodules, an injection can rarely block a blood vessel and injure skin or vision. Sudden visual symptoms, unusual severe pain or skin colour change after injection require immediate medical assessment.[1][2]

Compare your options

Compare an immediate volume goal with gradual collagen stimulation, muscle-related lines and surface texture. The relevant alternative depends on anatomy and cause, rather than choosing a product from a photograph.[1]

How we use evidence

A controlled trial compares interventions in defined groups; an uncontrolled cohort cannot, alone, establish causality. A review depends on the quality of its included studies. We distinguish these sources from manufacturer information and identify when findings do not directly apply to the platform or protocol.

The date records when sources were checked for this guide. It is not a statement of individual clinical review, product authorisation or confirmation of the clinic’s available configuration.

This guide supports a conversation with your clinician. It does not determine your suitability or replace individual aftercare instructions.

Regulatory sources describe their own jurisdictions; a US authorisation or warning does not determine a product’s legal status in Portugal.

Start with your priorities.
