Use of a Serum With the Infinite Glow® Device Improves Signs of Facial Aging: A Split-Face Case Report Using VISIA Analysis.
Matrixyl · Cureus · 2026 · Observational · n=1
The combined use of a topical serum and a multi-technology device showed some improvements in facial aging signs, particularly in wrinkle reduction, but further research is needed to confirm these results.
TruSkin age decreased by five years on the treated side with the device + serum and by one year on the serum-only side.

Multi-omic analysis reveals that the <i>CARNS1</i>-mediated carnosine synthesis pathway modulates muscle metabolic responses to nutrient restriction in goats.
Matrixyl · Animal nutrition (Zhongguo xu mu shou yi xue hui) · 2026 · Observational · n=30
Maintaining feed intake at a minimum of 75% during seasonal feed shortages may prevent irreversible muscle damage in goats.
Average daily gain in the RF50 group decreased markedly compared with the RF0 group (P < 0.05).

Integrated transcriptomic and metabolomic analyses provide new insights into the response of black rockfish (Sebastes schlegelii) larvae to temperature fluctuations.
Matrixyl · Comparative biochemistry and physiology. Part D, Genomics & proteomics · 2026 · Observational
Black rockfish larvae show significantly reduced survival rates under constant high temperatures compared to fluctuating temperatures, indicating different physiological stress responses.
Survival rate in the HT group was 38.89%, significantly lower than that in the other three groups (P < 0.05).

Baseline gut microbiome ecology predicts long-term fat mass loss after bariatric surgery: evidence for a thrifty &lt;i&gt;Bifidobacterium&lt;/i&gt; phenotype.
Matrixyl · Gut microbes · 2026 · Observational · n=106
Higher baseline levels of Bifidobacterium spp. may be linked to less fat mass loss after bariatric surgery, suggesting a need for personalized approaches based on gut microbiome profiles.
Patients in the highest quartile of baseline Bifidobacterium spp. lost 6.6% fat mass at 24 months compared to 13.2% in the lowest quartile, p=0.010.
C
grade
A liposome-hydrogel composite ameliorates UVB-induced mouse skin photoaging through integrated antioxidant and extracellular matrix remodeling pathways.
Matrixyl · Drug delivery · 2026 · Observational · Preclinical
The study presents a liposome-hydrogel composite that may enhance the delivery of deer placenta polypeptides for skin protection against UVB-induced damage, but further research in humans is necessary.
2.7-fold enhancement in transdermal permeation.

Ethnopharmacological validation of the antinociceptive potential of Calotropis gigantea L. flowers: Phytochemical characterization, safety evaluation, and mechanistic insights from in vivo models.
Matrixyl · Journal of ethnopharmacology · 2026 · Observational · Preclinical
Calotropis gigantea shows promise for pain management based on its antinociceptive effects in rats, but further research is needed to confirm its efficacy in humans.
IC50 value of 145.77 ± 4.30 μg/mL for DPPH free radical scavenging activity.

Nanostructure and Collagen-Stimulating Activity of Cationic Pentapeptide Lipopeptides.
Matrixyl · Journal of peptide science : an official publication of the European Peptide Society · 2026 · Observational
Both C16-KTTKS and C16-RTTRS lipopeptides stimulate collagen production in Human Dermal Fibroblasts at a low concentration of 0.0062 wt%. However, the clinical relevance of these findings remains uncertain.
Collagen production stimulated at low concentration (0.0062 wt%) in Human Dermal Fibroblasts.

Synergistic Effects of Injectable Platelet-Rich Fibrin and Bioactive Peptides on Dermal Fibroblast Viability and Extracellular Matrix Gene Expression: An In Vitro Study.
Matrixyl · PubMed · 2025 · Observational · Preclinical
The study suggests that combining injectable platelet-rich fibrin with bioactive peptides may enhance dermal fibroblast viability and gene expression, but further research is needed to confirm these effects in clinical settings.
