Does Dissolving Filler Affect Your Natural Hyaluronic Acid?
one of the most frequently asked questions when considering filler . Fortunately, the answer is largely and in science.
How Hyaluronidase Works
is the enzyme used to break down acid (HA) fillers. Whilst it does affect both the injected filler and your body’s HA temporarily, the impact on your HA is and . this is key to alleviating about long-term tissue damage.
Hyaluronic Acid in Human Tissue
The human body contains 15 grammes of hyaluronic acid in total, distributed throughout various tissues:
Skin: Approximately 50% of the body’s total HA resides in the skin, where it maintains hydration, plumpness, and structural integrity
Eyes: The vitreous humour contains significant HA concentrations, to its gel-like consistency
Joints: fluid relies on HA for and shock absorption
tissues: HA is throughout the extracellular matrix, providing tissue support and facilitating cell migration
The amount of HA in dermal fillers is modest compared to your body’s total HA content — typically 0.5–2ml of containing 20–25mg of HA per . This contextualises why the local depletion caused by impact tissue health.
How Much HA is in the Face?
The face 7–8 grammes of hyaluronic acid, half of the body’s total HA . This is distributed throughout:
Dermis: The deeper layers of facial skin the majority of HA, providing support and hydration
Epidermis: The outer skin layer smaller amounts but plays a role in surface hydration and function
Subcutaneous tissue: HA is present in the fat pads and connective tissue that give the face its three-dimensional contours
This natural facial HA is being renewed, with approximately one-third being synthesised and degraded daily normal . This is a sign of healthy, tissue maintenance.
What Happens During and After Dissolution
Hyaluronidase breaks down both filler and some natural HA in the area. This is why some people notice flatness or slight hollowing immediately after dissolution — it’s a localised, effect, not permanent tissue loss.
24–48 hours: Most activity occurs within the first two days. The enzyme is rapidly metabolised and cleared from the tissue
2–4 weeks: Your body begins actively regenerating natural HA. Fibroblasts in the skin ramp up production of new acid as part of normal tissue repair and maintenance
1–3 months: HA levels return to . Given that your body naturally and breaks down about one-third of its total HA every day, is a constant, ongoing biological process
Will You Look Worse Than Before You Had Fillers?
In most cases, no. Here’s why this fear is unfounded:
Natural regeneration: Your body continuously new HA through fibroblast activity, so any is restored through normal processes
No permanent damage: doesn’t harm or the fibroblasts that HA, so your fully intact
Localised effect: The enzyme works in the injection site, not systemically throughout your entire body or even your entire face
Return to baseline: Most people return to their pre-filler appearance, not a worse state. You’re your face, not a version of it
However, there are some factors to bear in mind:
post-dissolution, the treated area may appear slightly due to both filler removal and temporary HA depletion
If you’ve had fillers for many years, you may have become to the enhanced volume, making your features seem less full by (though objectively from your baseline)
Any swelling from the original filler that was masking volume loss or structural changes will now be revealed
Oedema and inflammation from the procedure itself can alter your before settling
The Ageing Process Doesn’t Stop with Fillers
This is perhaps the most point that’s often overlooked: whilst you have fillers, the natural ageing continues . This is not something people are warned about, and it can lead to significant when fillers are .
When someone has had fillers for several years and then dissolves them, they may be shocked by their appearance — but this is typically due to biological ageing, not tissue damage from hyaluronidase. Here’s what’s been occurring all along:
Bone resorption: Facial bones recede with age, particularly around the eyes, cheeks, and . This process continues whether you have fillers or not, creating a less robust foundation
Fat pad descent and atrophy: Facial fat pads shift and in volume over time, hollows and sagging that may have been entirely
and loss: Your skin loses approximately 1% of its per year after age 20, leading to thinner, less supported, and less skin
Natural HA decline: Even without dissolving fillers, your body produces progressively less HA as you age — by age 50, you may have half the HA you had at 20
Muscle changes: Facial weaken, thin, and change position with age, affecting overall facial structure and contours
Skin laxity: Loss of elasticity means the skin doesn’t « snap back » as it once did, to sagging and jowling
Consider this scenario: if you had placed at age 30 and them at age 40, you’re your current 40-year-old face (without fillers) to your 30-year-old face (before fillers). That’s a decade of biological ageing that occurred whilst the fillers were volume and these progressive changes.
During those ten years:
Your bone structure has changed
Your fat has shifted
Your skin has thinned and lost elasticity
Your collagen and HA production has declined
The fillers were « freezing » your appearance at a certain point, whilst your underlying facial continued to age. When you remove the fillers, you’re not seeing damage — you’re seeing .
Because the fillers were a more youthful appearance, them reveals the accumulated of ageing all at once. This can feel and alarming, some people to believe that the hyaluronidase « dissolved their face » or caused permanent tissue damage.
In reality, they’re simply seeing what their face looks like at their current age without — something they would have gradually if they’d never had fillers at all. The shock comes from the sudden revelation, not from actual harm.
This is critical: the removed the filler and affected local HA (which regenerates within weeks), but it did not cause the bone loss, fat atrophy, collagen degradation, or skin laxity that naturally over the years you had .
Your baseline has changed because you’ve aged, not because the harmed your tissues. The enzyme simply what was already there — your true, current face.
Supporting Natural HA Production During Healing
Whilst your body will naturally regenerate HA, you can this process:
Hydration: Drink plenty of water to support HA synthesis and overall skin health
Nutrition: Ensure adequate intake of C, zinc, and magnesium, which are cofactors in and HA production
Skincare: Use topical HA serums to provide surface whilst your skin regenerates its deeper HA layers. Look for different molecular for multi-level hydration
Avoid trauma: Give the area time to heal before considering any further procedures
Sun protection: UV damage HA and accelerates collagen breakdown, so use SPF 30+ diligently
Gentle skincare: Avoid harsh exfoliants or treatments immediately post-dissolution
Consider supplements: Some evidence suggests that oral HA supplements may support skin hydration, though topical application and natural remain primary
Conclusion: Understanding the Real Picture
The fear that will leave you looking worse than before is but largely unfounded when you understand the science. Yes, hyaluronidase temporarily affects natural HA levels in the treatment area, but your body’s regenerative normal levels within weeks to a few months. The fibroblasts that HA remain undamaged, and the enzyme’s effect is and transient.
You won’t look worse than before you had — you’ll return to your natural . However, it’s to that if you’ve had fillers for several years, your has shifted due to the march of time. The bone resorption, fat redistribution, loss, and skin changes that occurred during that period are not caused by filler dissolution — they’re the result of biological ageing that was happening all along, merely masked by the volumising effect of the filler.
When someone feels they look « worse » after dissolution, they’re usually one of two things:
The revelation of accumulated ageing that occurred whilst fillers were in place
Adjustment to their natural appearance after becoming accustomed to features
Neither of these tissue damage or permanent HA depletion.
The key to a successful dissolution experience is threefold:
Realistic expectations: Understand that you’re to your current state, not your state from years ago
Adequate time: Allow 2–3 months for full HA regeneration and tissue settling before making further decisions
Supportive aftercare: Nourish your skin through proper hydration, nutrition, sun protection, and gentle skincare to optimise natural regeneration
If you’re considering filler dissolution, discuss your concerns openly with a practitioner who can assess your situation, manage expectations realistically, and support you through the healing process. Remember: hyaluronidase is a tool for correction, not . Your face will heal, your HA will regenerate, and you’ll return to your authentic self — which, whilst it may show the natural effects of time, is not damaged or diminished by the itself.
