Hyaluronic Acid and Vitamin C: what the published research says
PubMed indexes 8 records that name Hyaluronic Acid and Vitamin C together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Hyaluronic Acid and Vitamin C. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
8 studies naming Hyaluronic Acid and Vitamin C.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
The Journal of dermatological treatment · 2025 · PMID 41117156
Randomized Controlled Trial
“The hyaluronate-based combination therapy effectively improved POH, demonstrating significant esthetic enhancement and quality of life improvement. This minimally invasive approach proved safe, effective, and highly satisfactory, presenting a promising treatment option for periorbital hyperpigmentation.”
Names both Hyaluronic Acid and Vitamin C in its title.
“Observation of the investigated skin parameters did not show superior effects of the addition of hyaluronic acid (HA) to collagen. Therefore, the ability of supplementation with HA to improve the effects on investigated skin parameters beyond the supplementation of collagen alone cannot be confirmed.”
Names both Hyaluronic Acid and Vitamin C in its title.
The journal of sexual medicine · 2024 · PMID 38721680
Randomized Controlled Trial
“The oral formulation of HA, chondroitin sulfate, N-acetylglucosamine, and vitamin C could be an effective therapy against urinary and sexual distress in participants with rUTI (NCT06268483; ClinicalTrials.gov).”
Names both Hyaluronic Acid and Vitamin C in its title.
“The combination of rehabilitation based on McKenzie back exercises and oral viscosupplementation with Fortigel®, Vitamin C, sodium hyaluronate, manganese and copper represents a valid option in patients with chronic LBP, as it ensures pain relief and improvement in the quality of life and in lumbar spine functionality. These therapeutic benefits are more evident and long-lasting compared to those obtained with rehabilitation alone.”
Names both Hyaluronic Acid and Vitamin C in its title.
The Journal of dermatological treatment · 2026 · PMID 41489066
Human subjects
“IPL combined with NCSH/TXA/VC mesotherapy provided safe, effective, and well-tolerated improvement in facial photoaging, representing a promising multimodal rejuvenation approach.”
Names both Hyaluronic Acid and Vitamin C in its title.
Journal of molecular histology · 2026 · PMID 42501143
Animal study
“At day 22, the combined HA + vitamin C regimen showed the highest collagen deposition and collagen type I immunopositive area among the tested groups, whereas the fibroblast-like cell-count finding was less robust. These preliminary findings are limited to late histological and immunohistochemical outcomes in a small sutured-incision model and do not establish functional benefit or an HA-vitamin C interaction.”
Names both Hyaluronic Acid and Vitamin C in its title.
“Our results demonstrated that both VC and HA had therapeutic effects on tendon healing, especially in the late phase. Level of Evidence I; High quality randomized trial with statistically significant difference.”
Names both Hyaluronic Acid and Vitamin C in its title.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Hyaluronic Acid, Vitamin C, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
