Hyaluronic acid in 30 seconds
Hyaluronic acid (HA) is a molecule the body produces naturally,it sits in skin, joints, eyes, and connective tissue, where its main job is to hold water. One gram can bind up to 1000 grams of water. As a supplement, it's used to support skin hydration, elasticity, and joint comfort from the inside. The research-backed dose is 120–240 mg per day.
Heey!'s Beauty Collagen is a 100% vegan capsule built around the patented Coll-egan® plant-based collagen-alternative plus 75 mg sodium hyaluronate, 300 mg MSM, vitamin C, biotin, B-vitamins, zinc, and selenium. 264 SEK per bottle, 90 capsules, 45-day supply at 2 capsules daily, made in Sweden.
What is hyaluronic acid?
Hyaluronic acid is a glycosaminoglycan,a long sugar-based molecule. Your body produces it on its own. About 50% of your body's hyaluronic acid is in the skin, where it pulls water into the tissue and keeps it there. The rest is in joints (as part of synovial fluid), in the eye's vitreous gel, and in connective tissue throughout the body.
Production peaks in your twenties and declines with age. By 50, most people have about half the hyaluronic acid in their skin compared to age 25. That's one of the reasons skin loses fullness and elasticity over time. Supplements aim to give the body more raw material to work with.
Supplement vs skincare,what's the difference?
Hyaluronic acid is used both topically (creams, serums) and as a supplement (capsules, powders). They work differently and complement each other rather than compete:
| Format | How it works | Best for |
|---|---|---|
| Supplement (oral) | Broken down in digestion, then absorbed building blocks support the body's own production from within | Skin moisture, elasticity, joint support,systemic effects |
| Skincare (topical) | Pulls moisture into the upper layers of skin while applied; does not penetrate deeper without modification | Immediate skin plumping and surface hydration |
The two formats target different layers,supplements work from the inside, skincare from the outside. People often use both together. Heey! Beauty Collagen is the supplement side of the equation; pair with whatever skincare routine you already have.
What does the research show?
Multiple clinical trials on oral hyaluronic acid supplementation report measurable improvements in skin moisture and elasticity within 8–12 weeks at doses of 120–240 mg per day. A 2017 randomized trial (Kawada et al., published in Nutrition Journal) found significant improvement in skin wrinkles and shine after 12 weeks of oral HA supplementation at 120 mg/day.
For joints, evidence is more mixed but consistently positive at the low end. A 2008 study in Nutrition Journal on oral hyaluronic acid for knee osteoarthritis reported reduced pain scores after 8 weeks of supplementation. EFSA has not approved a specific health claim for oral HA, but Heey! Beauty Collagen carries vitamin C and biotin claims that are EFSA-approved,for normal collagen formation (vitamin C) and maintenance of normal hair (biotin).
How to dose hyaluronic acid
- Dose: 120–240 mg per day from supplements. Heey! Beauty Collagen provides 75 mg sodium hyaluronate per 2-capsule daily dose, paired with cofactors (MSM, vitamin C, biotin, zinc) that support the body's own production.
- Timing: With or without food, daily. Hyaluronic acid is gentle and doesn't compete with other supplements for absorption.
- Consistency: Effects build over 8–12 weeks. Don't judge it on the first week.
- Pair with: Adequate hydration. Hyaluronic acid binds water,give it water to bind.
- Combine with: Vitamin C (for collagen synthesis), zinc, biotin (for skin/hair/nail support). Heey! Beauty Collagen includes all three at 50–100% NRV.

Frequently asked questions
Q: What is hyaluronic acid?
A: Hyaluronic acid is a molecule the body produces naturally. It sits in skin, joints, and connective tissue, where it binds water and helps maintain hydration, elasticity, and joint cushioning. One gram of hyaluronic acid can bind up to 1000 grams of water.
Q: Does oral hyaluronic acid actually work?
A: Clinical studies at 120–240 mg per day show measurable improvements in skin moisture and elasticity within 8–12 weeks. Effects are more modest than topical hyaluronic acid in the short term, but systemic,supporting the whole body, not just the area where cream is applied.
Q: How much hyaluronic acid should I take per day?
A: 120–240 mg per day is the dose range used in most clinical studies. Heey! Beauty Collagen provides 75 mg sodium hyaluronate per daily dose alongside cofactors (MSM, vitamin C, biotin, zinc) that support the body's own hyaluronic acid and collagen production.
Q: How long before hyaluronic acid supplements show effects?
A: Most studies measure visible skin effects at 8–12 weeks of daily use. Joint comfort effects, where studied, appear in similar timeframes. Don't expect overnight results,this is a building-block approach, not a topical quick-fix.
Q: Is hyaluronic acid vegan?
A: It depends on the source. Hyaluronic acid can be extracted from rooster combs (animal source) or produced by bacterial fermentation of plant carbohydrates (vegan source). Heey! Beauty Collagen uses 100% vegan-sourced sodium hyaluronate.
Q: Can I take hyaluronic acid every day?
A: Yes. Hyaluronic acid supplements are safe for long-term daily use at recommended doses. No tolerance build-up, no fade in effect.
Q: Hyaluronic acid supplement vs serum,which is better?
A: They serve different purposes and are complementary. Supplements support the body's own hyaluronic acid production from the inside. Serums hydrate the upper layers of skin from the outside. Most studies on visible skin improvement show benefits from either alone and additive benefits from combining them.
Q: Can I take hyaluronic acid with collagen?
A: Yes,they're often combined. Vegan collagen alternatives like Coll-egan® supply the amino acid building blocks for the body's own collagen production, while hyaluronic acid supports the matrix that collagen forms. Heey! Beauty Collagen combines both in one formula.
Q: Are there side effects of hyaluronic acid?
A: Side effects are uncommon at recommended doses. Some people report mild digestive issues if starting at a high dose; building up gradually solves this. Speak to a doctor before supplementing if pregnant, nursing, or on blood thinners.
Q: How long does one bottle of Heey! Beauty Collagen last?
A: 90 capsules per bottle, 2 capsules per day = 45-day supply. Approximately 5.87 SEK per daily dose.
