Can a serum truly mimic the effects of cosmetic fillers? The latest buzz in skincare, dubbed "filler in a bottle" on social media, promises just that. Beauty journalist Sabine Wiesel, in her 40s, was among the first to put The Ordinary's new Volufiline 92% + Pal-Isoleucine 1% serum to the test over a rigorous month-long trial.
Putting the Hype to the Test
Launching on Friday 09 January 2026, the serum targets a key concern of natural ageing: volume loss. As skin matures, collagen, elastin, and facial fat pads diminish, leading to hollow under-eyes, less plump cheeks, and more pronounced smile lines. The star ingredient, volufiline (a trade name for sarsasapogenin), is a fusion of plant extracts said to stimulate lipid storage to restore volume.
The Ordinary, renowned for its accessible, science-backed formulations, has combined volufiline with pal-isoleucine. This supporting ingredient aims to boost elastin and collagen production, enhancing the plumping effect and softening lines.
"As someone who regularly struggles with dark, hollow under-eyes, I was keen to see how it performed," notes Wiesel, who has never had dermal filler. She incorporated the 15ml serum into her morning and evening routine for 30 days, applying it directly to targeted areas after moisturiser.
The Application and Initial Impressions
The serum's consistency is runny and oily, requiring a sparing hand. "Using it sparingly is key – it can feel greasy on the skin if you use too much," Wiesel advises. The packaging features a one-drop dropper, which she found practical for controlling dosage despite missing the brand's typical pipette.
A noticeable tingling sensation, particularly under the eyes, occurred upon application. The brand confirms this is normal, and Wiesel did not find it irritating enough to discontinue use.
The Results: A More Youthful Appearance?
Wiesel advises managing expectations: rejuvenation doesn't happen overnight. However, after consistent use for a month, she observed visible differences.
The most significant change was around her eyes. "My under-eyes started to look plumper, with shadows less noticeable. Before use, I looked tired and sometimes even unwell. Now, I feel I look brighter and healthier."
She also noted improvements in her cheeks and smile lines. "My cheeks also look slightly plumper, and my smile lines somewhat softer... they feel firmer and more youthful."
Despite these positive results, Wiesel offers a crucial reality check. While the serum offers a natural, topical alternative, it cannot replicate the dramatic results of injectable dermal fillers.
Is It Worth the Investment?
Priced at £20, The Ordinary's serum makes the trending volufiline ingredient accessible. Wiesel concludes it is an affordable and effective option for those seeking to target volume loss, particularly praising its impact on her under-eyes and cheeks.
However, the formula may not suit all skin types. Fellow IndyBest beauty writer Lucy Smith, who tested it on her late-twenties oily skin, experienced blemishes and sensitivity. This suggests the product might be better suited to more mature, drier complexions.
Wiesel's final verdict? For individuals in their 40s and beyond experiencing natural volume loss, this serum is a worthwhile, value-driven addition to a skincare regimen, delivering noticeable plumping effects with disciplined, long-term use.
