Why I stopped recommending filler to my clients.
Most women think of filler as an anti-aging treatment. It isn't and after years of dissolving it, I want to explain what it actually does, what it can't, and what to reach for instead.

Volume is not the same as skin quality. Filler changes shape. It does nothing for the collagen and elasticity that actually make skin look young.
Half of my week is now spent dissolving filler, not injecting it. The clients in my chair aren't chasing a new look — they're trying to undo one. And almost all of them arrive believing the same thing: that filler was going to make their face look younger.
It was never going to. Filler only changes volume and contour. It has no effect on how your skin ages — the collagen, the elasticity, the texture and glow that actually read as “youthful.” Fill a face that's lost skin quality and you don't turn back the clock. Over time, volume alone can make features look heavier and less natural.
I'm not anti-filler. Used sparingly and well, it has a place. But three myths keep sending women down a road they later regret, so let me correct them the way I do across the desk.
The 3 myths I correct every week
1
The myth
“More filler looks more lifted.”
The “pillow face” effect — swollen, not lifted.
The reality
Past a certain point, filler doesn't lift — it weighs down. This is the “pillow face” effect: the face looks swollen and distorted rather than lifted. A genuinely youthful face is defined and elastic, not overfilled.
2
The myth
“It stays exactly where it's injected.”
Migration shows up as puffiness & loss of definition.
The reality
Filler migrates. It can travel beyond the injection site over time, causing puffiness, heaviness and loss of definition — most visibly under the eyes and around the mouth. And once it migrates, it's difficult to fully reverse.
3
The myth
“It all dissolves in 6–12 months.”
The reality
Not always. Imaging studies show filler can linger for years — long after you assume it's gone. That lingering product is linked to chronic swelling, fibrosis and gradually distorted facial anatomy.
“Filler answers a question about shape. Aging skin is a question about biology. They are not the same fix.”
— Felicia K.
So what actually makes skin look younger?
Young skin isn't about volume — it's about function. It makes collagen readily, holds moisture, turns over and repairs itself. That's what gives skin bounce, evenness and glow. When we “look tired,” it's usually skin quality talking, not a lack of volume. So the fix isn't to inflate the face. It's to get the skin repairing itself again.
That's where a different category comes in: regenerative skincare, rather than cosmetic. The one with the strongest science behind it right now is PDRN. But almost nobody actually knows what it is.
So — what on earth is Salmon DNA, aka PDRN?
Let's get the weird part out of the way. PDRN stands for polydeoxyribonucleotide. In plain English, it's a fragment of DNA and yes, the most bio-compatible source happens to be salmon. That's where the nickname comes from.
◆ PDRN, explained
The 20-second version
Your skin repairs itself using signals from cells called fibroblasts. The same cells that make collagen and elastin. As you age, those cells slow down. PDRN acts like a wake-up call for them. Instead of sitting on top of your skin like most creams or propping it up like filler, it prompts your skin to rebuild its own structure from within.
Salmon DNA is used because, at the molecular level, it's remarkably similar to human DNA, which means skin recognizes it and puts it to work rather than rejecting it.
Unretouched, 2.5 months of daily use. Firmer, brighter, more even skin — from the skin repairing itself, not from added volume. Individual results vary.
If you're going to try it, get two things right
The moment an ingredient trends, the market floods with underdosed versions. If you try PDRN, two things decide whether it's worth your money:
Dose. Many products list PDRN and include a trace. For a topical you use daily, you want a serious concentration — atleast 30,000 PPM is the meaningful benchmark for at-home use.
Source and formula. Insist on real salmon-derived PDRN rather than a synthetic imitation, in a short, fragrance-free formula gentle enough for daily use on sensitive skin.
When clients ask which one fits that description, the one I point them to is a Korean-made ampoule called YURSLF — 50,000 PPM, real salmon-derived PDRN, fragrance-free and formulated for sensitive skin. It's the rare case where the product that trends online and the one I'd actually recommend are the same thing.

Who this is really for
If you've been considering filler or already have filler and want to protect your skin underneath it, or you're looking for a needle-free way to actually improve how your skin ages, this is squarely for you.
“The women who regret filler almost never regret it for the volume. They regret it because they thought it would fix their skin and it was never going to.”

To think about all the money I spent on filler… smh. Since using this my skin looks naturally plump and smooth — like it did before I ever started injecting.

This is exactly the shift I hope for, Menna — treating the skin instead of inflating the face. Glad it's working for you.

I still get filler occasionally, but my skin doesn't hit that “flat” phase between appointments anymore. It stays fresh and bouncy longer, so I'm not rushing to rebook. Wish I'd understood the difference years ago.
