Enhanced Facial Rejuvenation: Biostimulatory Effects of Hylan Gel Dermal Filler DX on Collagen Synthesis and Tissue Regeneration.
Article in Aesthetic plastic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFacial rejuvenation involves addressing the breakdown of collagen and elastin that occurs with aging. Hyaluronic acid (HA)-based dermal fillers have become a key non-invasive treatment, known for their volumizing effects and potential regenerative benefits. This study characterizes the physicochemical and rheological properties of Hylan Gel Dermal Filler DX, a novel filler combining HA and dextranomer microspheres, and evaluates its capacity to enhance extracellular matrix regeneration.
methodsRheological analysis was conducted to determine viscoelastic properties, including storage modulus (G'), loss modulus (G''), and tan delta across frequencies (0.1-10 Hz). In vitro experiments with normal human dermal fibroblasts (NHDFs) and monocytes (J774A.1) assessed the effects of Hylan Gel Dermal Filler DX (HA + DX), Genefill Soft Fill (HA), HarmonyCa® (HA+CaHa), Radiesse® (CaHa), and Sculptra® (PLLA). Hydration and wound healing assays were also performed. Biomarker analysis focused on collagen types I, III, IV, VI, elastin, and cytokines (TGF-β1, IL-1β, IL-6, IL-10, TNFα).
resultsRheologically, HA + DX displayed a balanced elastic and viscous profile, supporting its structural integrity and adaptability in dynamic facial areas. HA + DX demonstrated high stimulation of collagen types I, III, IV, VI, and elastin production, with enhanced fibroblast migration and wound healing at 72 hours compared to other fillers. HA + DX also modulated cytokines, increasing TGF-β1 and IL-10 while reducing TNFα and IL-1β, suggesting anti-inflammatory and regenerative properties.
conclusionsHA + DX exhibited considerable benefits in collagen stimulation, wound healing, and cytokine modulation. Its favorable rheological characteristics and regenerative potential make it a promising option for facial rejuvenation and tissue regeneration.
