Why My Hyaluronic Acid Filler Swells Months After Injection?
Why my hyaluronic acid filler swells months after injection?
Is it normal for fillers to swell months later? Advice from Beauty Bar in Ware Hertfordshire
Cross linked hyaluronic acid (HA) fillers can cause swelling even years after injection due to several reasons
Hygroscopic nature and water retention
- Hyaluronic acid is very hygroscopic, meaning it attracts and binds water from surrounding tissue.
- Even years after being injected, cross linked HA remains in the skin as a gel, dynamically responding to body fluid balance.
- High temperature or inflammation increases vascular permeability, which leads to fluid accumulation in HA and localised swelling.
Metabolic changes and inflammatory response
- HA undergoes slow degradation by hyaluronidase enzymes and oxidative process.
- During fever, infections, or autoimmune reactions, the body releases pro-inflammatory cytokines (IL-6, TNF-α).
They activate HA degrading enzymes, altering its structure and causing swelling, and increase vascular permeability, leading to fluid retention in areas with dermal filler.
Interaction with the extracellular matrix
- HA exists in dynamic balance with proteins, collagen, and water in the skin.
- Over time, skin aging, collagen loss, and tissue changes can affect placement of HA, this leads to localised swelling or shifting of the filler.
Late-onset immune reactions
- Some people may develop delayed immune responses to HA, especially after infections, vaccinations, or immune system fluctuations.
- This can trigger formation of granulomas or chronic inflammation, which could lead to temporary swelling years after your treatment.
This phenomenon is documented in scientific literature and is not uncommon!
