Private Label Hyaluronic Acid Serum
Multi-weight HA hydration serums that feel plumping, not sticky — the safest first SKU for any new brand.
Hyaluronic acid serums are the lowest-risk entry SKU in skincare: universally tolerated, season-proof and easy to claim. The formulation craft is in the molecular-weight blend — high-weight HA sits on the surface for immediate smoothing, low-weight fractions travel deeper for lasting comfort.
We cap watery builds around 1% total HA because above that the serum pills under makeup and dries tacky, which shows up in reviews. Cross-linked HA and HA powder grades are available for premium cushion textures.
What you can change on this build
- Weight-blend tuning: surface-plumping vs deep-comfort profiles
- Formats: dropper, pump, airless or ampoule course
- Add-on actives: B5, ceramides, beta-glucan, ectoin
- Fragrance-free base for sensitive positioning
- Sample plan: 5–7 days for stock-adjacent builds

Before you brief a supplier on this category, these are the guides that answer the questions buyers ask next — timelines, order quantities, cost structure and compliance.
What sits behind this fluid's claim
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Sodium Hyaluronate (high MW) | 0.1–0.3% | Surface film, instant smoothing |
| Sodium Hyaluronate (low MW) | 0.1–0.5% | Deeper hydration comfort |
| Hydrolyzed Hyaluronic Acid | 0.05–0.2% | Penetrating fraction |
| Panthenol (B5) | 1–2% | Soothing humectant pairing |
How a fluid goes from brief to released batch
- 1
Adjust and hold the pH
pH is set with the buffer system and then held, rather than corrected repeatedly at the end of the batch.
- 2
Clarify by filtration
Filtration is matched to the viscosity so the product stays clear without stripping out what gives it body.
- 3
Set the pH window
The range is defined by the most sensitive active in the system, with a tolerance production can actually hold.
- 4
Verify dosage across the pack
Where the pack meters a dose, the delivered volume is checked across the life of the pack rather than only when it is full.
Stability and shelf-life questions
Why do some HA serums feel sticky?
Usually total HA above 1% or a single low-weight fraction. We balance molecular weights so the serum dries to a soft finish under makeup.
What is the difference between HA and sodium hyaluronate?
Sodium hyaluronate is the water-soluble salt used in virtually all serums — it is the standard INCI on the label. We can declare either per your market's labeling preference.
Can HA be combined with retinol in one SKU?
Yes, commonly as a buffer claim. We also build twin-pump packaging that keeps the two phases separate until application.
Why a fluid is checked against a sample, not a number
Assay and pH tell you whether the chemistry is right; they do not tell you whether the product looks the way the buyer approved. Colour and clarity are read against the retained Golden Sample.
Production runs on GMPC and ISO 22716 certified lines under manufacturing licence 粤妆20250206, traceable from raw material to carton on every batch.
Solubilisation has a ceiling
An oil-soluble active can be carried in a water-based fluid with a solubiliser, but only up to a point. Past that point the system turns hazy and then separates, and the point moves with temperature and with everything else in the formula.
The haze is not a cosmetic problem — it is the first visible sign of a system that has run out of capacity. Where clarity is part of the brief, the loading is set below the ceiling with a margin for the coldest shelf it will sit on.
The fluid systems we build
In a fluid, protection and texture are set by different parts of the system — the route decides which one leads.
| Route | Barrier it needs | Where it fits |
|---|---|---|
| Concentrated serum gel | Airless pump to handle the viscosity | High-load actives sold on a small dose |
| Low-water fluid | Airless or aluminium-barrier pack | Actives sensitive to oxygen and light |
| Biphasic | Two phases, shaken before use | Formats that need an activation step |
| Two-chamber or mix-at-use | Separated phases until activation | Actives that cannot hold a shelf life in solution |
What holds this fluid together over its shelf life
Water quality is an ingredient
Purified water has its own specification, and it matters more here than in any other format because it is most of the formula.
A buffer has a capacity
A buffer holds pH only across a limited range of incoming acid or base. Beyond that it gives way, so the capacity is checked against what the formula will actually meet rather than assumed.
Preservation in a water-rich base
High water activity calls for a preservation study against the finished matrix, not a calculation from the raw material list.
Chelation is dosed, not added
Too little chelator leaves trace metals free to catalyse oxidation; too much can undercut the preservation system or shift the pH. The level is set against the water and the raw materials.
Every format this base can be filled in
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Multi-weight HA 0.5%, 30 ml dropper | 1,000 pcs | 10–15 days |
| HA 1% + B5 essence, 30 ml pump | 1,000 pcs | 10–15 days |
| Cross-linked HA cushion gel, 50 ml jar | 1,000 pcs | 10–15 days |
| HA + ceramide milk-serum, 30 ml airless | 1,000 pcs | 10–15 days |
MOQ and lead time above are the standard liquid, cream and gel route. The real minimum is set by the manufacturing system rather than the category: surfactant systems (shampoo, body wash) start at 2,000 pcs, stick formats at 3,000, and powders and sheet masks at 5,000 — with longer production runs to match.
