The Truth Hurts: Why Old Fillers Are Falling Out of Favour
The aesthetic world is at a turning point.
For years, hyaluronic acid (HA) dermal fillers have dominated non-surgical rejuvenation — and rightly so. They’ve helped countless patients feel better about themselves. But behind the glossy marketing and short-lived “wow” results lies a growing concern, both among practitioners and patients alike: many of the popular filler brands on the market today are no longer fit for the modern aesthetic consumer.
From high levels of BDDE (the chemical used to bind HA molecules) to the routine inclusion of lidocaine, many of these formulations were designed for mass-market use—not for long-term safety, purity, or truly natural outcomes.
Today’s patients are more informed. They demand transparency, minimal risk, and long-lasting beauty that looks like them, not like a filter. And it’s time the products we use caught up.

What’s Wrong With Traditional HA Fillers?
Here’s what most patients don’t know—and too few practitioners are willing to talk about.
- Impurity and Inflammation
Most legacy fillers contain residual BDDE, a chemical crosslinking agent that is often poorly metabolised and can linger in tissue. The more BDDE, the more modified the HA—and the more your immune system has to work to tolerate it.
Most fillers also contain lidocaine, added to reduce injection discomfort. But lidocaine can alter tissue behaviour, affect precision of injection, and trigger allergic reactions in sensitive patients. Worse, it masks bad technique, vascular occlusion and undesirable product properties.
The result? Puffiness, delayed inflammatory reactions, and poor integration, excessive bruising and swelling and worried patients post treatment. Kysense mitigates all these.
- Overcorrection Culture
The “millilitre mindset” has taken over. Many filler brands require more product to achieve lift or volume, leading to overfilled faces, distorted proportions, tissue hardness and rapid patient burnout.
This isn’t what modern beauty is about. Patients now want subtle enhancements, not unreal transformations.
- One Size Does Not Fit All
Old fillers offer limited flexibility across facial areas. Injectors often resort to mixing multiple brands and SKUs, each with slightly different tolerances, extrusion forces, and outcomes—complicating treatment and clinic logistics further.
