Quick Answer
Hyaluronic Acid Hair Nails Randomized Trial has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: Its decline is directly associated with cutaneous dehydration, underscoring its vital function in maintaining skin hydration.
Key Takeaways

- 02Such supplementation has been associated with multiple benefits, including the prevention of sagging and stretch marks, improved skin elasticity and hydration, stimulation of collagen synthesis, strengthening of connective tissues, cartilage, bones, and muscles, reduction in visible signs of aging, and promotion of cellular regeneration ().

The current Migaku evidence database contains 2 reusable source documents for Hyaluronic Acid Hair Nails Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove.
- Its decline is directly associated with cutaneous dehydration, underscoring its vital function in maintaining skin hydration. [González-Rodríguez Yaiza (2026); evidence level 2]
- Such supplementation has been associated with multiple benefits, including the prevention of sagging and stretch marks, improved skin elasticity and hydration, stimulation of collagen synthesis, strengthening of connective tissues, cartilage, bones, and muscles, reduction in visible signs of aging, and promotion of cellular regeneration (). [González-Rodríguez Yaiza (2026); evidence level 2]
- 64.60 ± 2.89; < 0.01) was found in the MKARE® group after 28 days compared to the baseline measurements. [González-Rodríguez Yaiza (2026); evidence level 2]
- in vivo 1 The skin, serving as the first protective barrier of the body, possesses a complex mechanical structure. [González-Rodríguez Yaiza (2026); evidence level 2]
- The aim of this narrative review is to evaluate the evidence for several of the most common supplements for hair, skin, and nails, as well as potential concerns. [Shing Vivian (2025); evidence level 3]
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.
