Private Label Niacinamide Serum
The workhorse active of modern retail — built with flushing-risk control and honest concentration claims.
Where the compliance file comes from
The line is GMPC and ISO 22716 certified, and each batch carries raw-material-to-carton traceability under licence 粤妆20250206.
For a fluid the file is built on the preservation and stability studies run against the finished matrix, with the certificate of analysis, stability summary, microbiology report and MoCRA / CPNP-ready documentation attached to the order. Colour and clarity are read against the retained Golden Sample at release.
From brief to released fluid, step by step
- 1
Verify the water first
Purified water is checked against its own specification before anything is added, because it is the majority of the formula.
- 2
Screen solubility at the cold end
The batch is cooled to the coldest shelf it will meet and checked for haze, which is where an overloaded solubiliser system shows itself.
- 3
Verify against the retained sample
Assay, pH and appearance are checked at release against the sample your buyer approved.
- 4
Clarify by filtration
Filtration is matched to the viscosity so the product stays clear without stripping out what gives it body.
The active system and its working levels
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Niacinamide | 4–10% | Oil balance, tone evenness, barrier support |
| Zinc PCA | 0.5–1% | Sebum regulation partner |
| Panthenol | 1–2% | Comfort buffer for higher strengths |
| Tranexamic Acid | 1–3% | Spot-tone support in duo builds |

Private Label Tranexamic Acid Serum
The dark-spot answer that pairs beautifully with niacinamide — gentle enough for daily use.
Private Label Oil-Free Gel Cream
The lightweight everyday cream for oily and combination skin — matte finishes that layer clean.
Buyer guides for this build
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.
Niacinamide earns its shelf space by doing three jobs at once — oil balance, tone evenness and barrier support — but cheap raw material with high nicotinic acid impurity causes the flushing complaints that sink reviews. We specify low-impurity grades and validate pH 5.5–6.5 windows where the vitamin stays stable.
Builds range from gentle 4% for sensitive positioning to full 10% + zinc PCA for oily-skin claims. Every lot ships with certificate of analysis, and stability is run at 45 °C to simulate summer logistics.
Pack, claim and level options
- Strength tiering: 4% / 5% / 10% with matching claim sets
- Textures: watery essence, gel or light emulsion
- Sensitive-skin variant without fragrance or drying alcohol
- Pairing SKUs: cleanser + serum + gel-cream routine set
- Supplement facts panel and INCI review for US/EU entry
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 |
|---|---|---|
| 4% niacinamide + HA, 30 ml dropper | 1,000 pcs | 10–15 days |
| 5% + zinc PCA gel, 30 ml pump | 1,000 pcs | 10–15 days |
| 10% + 1% zinc, 30 ml glass dropper | 1,000 pcs | 10–15 days |
| 10% + tranexamic duo toner-serum, 100 ml | 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.
Questions we answer on every serum brief
Is 10% niacinamide always better than 5%?
No. Below 5% most oil-balance benefits are already delivered; higher strengths add flushing risk. We help you pick the strength that matches your claim and audience.
How is flushing risk controlled?
Low-nicotinic-acid raw material specification, pH window control and optional comfort actives like panthenol. The spec is written into your product dossier.
What MOQ applies to a 10% build?
From 1,000 pcs per SKU — the same floor for stock-adjacent bases and full custom textures.
What gets decided before the preservative system
Opaque is not a downgrade
Where an active is light-sensitive, an opaque or UV-filtered pack is part of the protection. Choosing clear glass for the look usually costs shelf life.
Trace metals at parts per million
Iron and copper catalyse oxidation far below the level any incoming specification would flag. A chelator is part of the design, not an optional additive.
The dropper or the pump
Dispensing decides dose consistency and how much air the product meets in use. It is a formulation-adjacent choice, not just a packaging one.
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.
Preservation is a design decision, not an additive
A water-based product needs a preservation system chosen against its own pH, its own water activity and the way it will be used. Choosing one before the formula is fixed almost always means redoing the work later.
The study runs against the finished matrix, and for anything dispensed by hand it runs against the in-use pattern as well, because that is where contamination actually enters the product.
Fluid bases and what each one can carry
Two fluids can look identical in the bottle and behave completely differently by the end of the shelf life.
| Route | Barrier it needs | Where it fits |
|---|---|---|
| Biphasic | Two phases, shaken before use | Formats that need an activation step |
| Structured gel | Chelator with no oil phase to protect | Treatment and gel-adjacent formats |
| Concentrated serum gel | Airless pump to handle the viscosity | High-load actives sold on a small dose |
| Glycol-rich fluid | Modest barrier, higher water activity | Actives that need solubility more than protection |
Start with the pH window
If your active has a narrow one, say so first — it decides more of the formula than any other single input. We reply with the matching base within 24 hours.
