This page provides general information and does not replace an individual medical consultation. Indication, product, technique and treatment plan are decided only after assessment; not every treatment is suitable for every person.
What it is
Hyaluronic acid fillers are injectable, absorbable gels. Different gels have different physical properties and are selected according to the anatomical area, tissue support and clinical objective.
What is assessed
The whole face is assessed: bone structure, tissue support, volume distribution and skin quality. The area that appears most noticeable is not always the area that would be treated.
How treatment is carried out
After assessment, medical history and informed consent, the area is cleaned and the gel is placed with a needle or blunt-tipped microcannula. Product and technique are medical decisions based on anatomy and risk.
Limits and alternatives
Fillers do not replace surgery and do not address skin quality in the same way as skin treatments. Duration varies with product, area and individual factors, and results cannot be guaranteed.
What the literature says
Hyaluronic acid is widely used and can be degraded with hyaluronidase when clinically necessary. Clinical guidance nevertheless emphasises that rare vascular occlusion requires immediate recognition and a prepared management protocol.
Risks and unwanted effects
Swelling, bruising, tenderness, lumps, irregularity and asymmetry can occur. Rare vascular occlusion may damage the skin and, very rarely, vision. Sudden severe pain, pallor, skin-colour changes or visual symptoms require urgent medical attention.
Contraindications and medical assessment
Treatment is generally avoided during pregnancy and breastfeeding and in active skin infection or inflammation. Allergy, autoimmune conditions, previous filler and medicines affecting bleeding require careful discussion.
Aftercare and follow-up
Swelling can temporarily alter the appearance. Following aftercare instructions and attending review allows the result to be assessed once the tissues have settled.
Frequently asked questions
Can hyaluronic acid filler be dissolved?
A doctor may use hyaluronidase when clinically necessary, although this is itself a medical treatment with risks.
How long does it last?
Duration depends on the product, area and person; an individual estimate is discussed during consultation.
