Hyaluronic acid is best known as a skincare ingredient, but in Japan it is just as familiar in capsules and beauty drinks. It is often paired with collagen, and brands abroad ask for the combination by name.
This guide is for brand owners planning an oral hyaluronic acid product made in Japan. It covers what the human studies show, who paid for them, how the ingredient is usually formulated, and what to fix before asking for a quotation.
Health supplements are foods, not medicines, and are not a substitute for medical treatment. Nothing here is a claim that any product prevents, treats or cures a disease.

What the research shows
A 2025 meta-analysis of seven randomised trials reported improvements in skin hydration, elasticity and wrinkle depth with oral hyaluronic acid, but the trials were small and varied in design.
| Study | Design | Reported result |
|---|---|---|
| Meta-analysis, Journal of Drugs in Dermatology 2025, 24(9):910–919 | 7 randomised controlled trials of oral hyaluronic acid | Significant improvements in skin hydration, elasticity and wrinkle depth; changes in firmness and water loss through the skin did not reach significance |
| Randomised, double-blind trial, Scientific Reports 2025 (PMC12827323) | 150 healthy Caucasian adults; 60 mg or 120 mg sodium hyaluronate a day, or placebo, for 12 weeks | The 120 mg group showed better skin hydration and elasticity and lower water loss through the skin than placebo |
| Double-blind, placebo-controlled trial, Nutrients 2021 (PMC8308347) | 40 healthy Asian adults aged 35–64; 120 mg hyaluronic acid a day or placebo for 12 weeks | Wrinkles, skin moisture, water loss through the skin and elasticity improved against placebo |
Three points to keep in view:
- Size. Seven trials is a small evidence base, and the meta-analysis authors called for larger, more robust trials.
- Population. Trials have been run in different populations, such as healthy Asian adults in the 2021 trial and healthy Caucasian adults in the 2025 trial. Check that a study’s participants resemble your market.
- Funding. The 2025 Scientific Reports trial was funded by an ingredient manufacturer, and its lead authors were employees of that company. It is common in this field. Read the funding line of any study you plan to cite.

What this means for your claims
“Studied for skin moisture” is accurate; “fills wrinkles” or “works like an injection” is not.
| Safer wording | Wording to avoid |
|---|---|
| ”Studied for skin moisture and elasticity" | "Fills wrinkles”, “replaces fillers" |
| "Contains 120 mg hyaluronic acid per daily serving” | Promises of visible results by a set date |
| Naming the study you cite, with its limits | ”Clinically proven” on its own |
In Japan, hyaluronic acid appears in Foods with Function Claims notified for helping to keep skin moist — a function of healthy skin, not a treatment. That tone is a useful model. Your own market’s rules govern your label abroad.

How hyaluronic acid is formulated
Daily amounts in trials are measured in tens of milligrams, so hyaluronic acid fits a capsule or tablet as easily as a drink.
| Dosage form | Why brands choose it | What to weigh up |
|---|---|---|
| Hard capsule or tablet | Small daily serving, low cost per day | Pairs easily with other beauty ingredients |
| Soft capsule | Combines with oil-based ingredients such as astaxanthin | Shell material and dietary suitability |
| Drink or jelly with collagen | The classic Japanese beauty combination | Collagen’s gram-level dose sets the format |
| Powder stick | Mixes into drinks | Taste and dissolving |
Decisions that shape the specification:
- Source and molecular size. Hyaluronic acid for foods is commonly made by microbial fermentation or extracted from chicken comb. The source affects dietary suitability. Molecular weight differs between materials; ask the supplier for its specification.
- Daily amount. Match the amount to any study you intend to cite — for example 120 mg a day in the 2025 trial above.
- Companion ingredients. Collagen peptide, ceramides, vitamin C and astaxanthin are common partners. Each needs its own check against Japanese food law and your market’s rules.
The check that comes first
Every ingredient must be permitted in foods in Japan, or a Japanese factory cannot make the product.
Hyaluronic acid itself is widely used in Japanese foods. Beauty formulas sometimes include botanical extracts that Japan treats as medicines, and one such ingredient stops the whole product. See the Japan-made supplement OEM page, and the collagen peptide and astaxanthin guides if you plan a combined product.
Before you ask for a quotation
A factory can quote accurately once the material, the daily amount, the form and the packaging are fixed.
- Hyaluronic acid source and specification
- Daily amount and servings per pack
- Dosage form
- Companion ingredients and their amounts
- Packaging
- Countries you will sell in, and first order and annual volume

Frequently asked questions
1. Does oral hyaluronic acid work for skin?
A 2025 meta-analysis of seven randomised trials reported improvements in skin hydration, elasticity and wrinkle depth. The trials were small, so describe it as studied for skin moisture and elasticity.
2. How much hyaluronic acid do studies use?
Tens of milligrams a day. A 2025 trial in 150 adults used 60 mg or 120 mg a day for 12 weeks, with the clearer results at 120 mg.
3. Is hyaluronic acid from fermentation or from chicken comb?
Both are used in foods. The source matters for dietary suitability and for how you describe the product.
4. Can I combine hyaluronic acid with collagen?
Yes. It is a common beauty combination in Japan. Collagen’s gram-level dose usually makes it a drink, jelly or powder.
5. Who funds hyaluronic acid research?
Often ingredient manufacturers. The 2025 Scientific Reports trial was funded by one. Check the funding statement of any study you cite.
