Does Oral Hyaluronic Acid Skin Health Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Oral Hyaluronic Acid Skin Health Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - Multi-omics analysis showed that QYG selectively remodeled gut microbiota, enriching Lactobacillus -, Bifidobacterium -, and Akkermansia -associated taxa, regulated serum metabolites related to energy and lipid metabolism, and enriched mitochondrial energy metabolism-related pathways in photoaged skin. [Yang Z (2026); evidence level 4] - In fibroblasts, QYG-containing serum restored mitochondrial membrane potential, reduced ROS accumulation and cellular senescence, and regulated AMPK/PGC-1α-associated markers. [Yang Z (2026); evidence level 4] - These findings support QYG as a promising food-medicine homologous functional food candidate for skin health maintenance through gut microbiota-associated systemic metabolic regulation. [Yang Z (2026); evidence level 4] - Bioactive food ingredients that regulate the gut microbiota are promising dietary strategies for supporting systemic health, but their roles in skin photoaging remain insufficiently defined. [Yang Z (2026); evidence level 4] - Oral SEP administration increased skin hydration and decreased TEWL, suggesting improved barrier function. [Lee C (2025); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
