Private Label Dark Circle Serum
The 8-hours-of-sleep illusion — targeted tone care for the under-eye.
Dark circle serum targets the most complained-about inch of skin: under-eye tone from visible vasculature and pigment look. The formulation stack pairs microcirculation support (vitamin K family, caffeine) with tone actives (niacinamide, peptides) — and the applicator does half the selling.
We keep fragrance out entirely for the eye zone, screen every active for ophthalmologist-reviewed safety, and offer ceramic-tip or cooling-metal applicators because the sensory cue of 'de-puffing cool' drives the demo video that sells this SKU.
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.
The route an aqueous base takes through production
- 1
Run preservation and stability together
Both studies run against the finished matrix, across the temperature range of the destination market.
- 2
Flush the headspace
Where oxygen-sensitive actives are present, the headspace is displaced before the pack is sealed.
- 3
Choose the barrier pair
Oxygen and light barriers are selected together with the pack, since either one alone leaves an oxidation route open.
- 4
Fix the active system
Routes and levels are set against the claim, then checked for compatibility with each other before the base is built.
What gets decided before the preservative system
Both ends of the pack's life
An airless pack keeps the product away from air, but it also changes how the last few grams are dispensed. The end of the pack's life belongs in the design as much as the first.
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.
Light is a reagent
UV accelerates the same reactions that heat does. Clear glass looks premium on a shelf and is usually the worst choice for a sensitive active.
Colour shift is the early warning
Long before an assay moves, a sensitive active usually shows a colour change. It is checked against the retained sample at release.
Formats and order quantities
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Vitamin K + caffeine brightening serum, 15 ml | 1,000 pcs | 10–15 days |
| Peptide + niacinamide tone build, 15 ml | 1,000 pcs | 10–15 days |
| Eye duo set (dark circle + depuffing roller) | 1,000 sets | 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.
A fluid has nowhere to hide a mistake
In a cream a small inconsistency can read as texture. In a clear fluid every undissolved particle, every trace of haze and every shift in colour is on display, and the customer sees it before they use a single drop.
That is why filtration, water quality and raw-material checks carry more weight here than in any other format. Nothing in a transparent product stays invisible.
Which fluid route fits which active
Each route below carries a different balance of preservative load, barrier requirement and sensory weight.
| Route | Barrier it needs | Where it fits |
|---|---|---|
| Concentrated serum gel | Airless pump to handle the viscosity | High-load actives sold on a small dose |
| Micellar system | Surfactant-stabilised, clear pack | Cleansing waters and no-rinse formats |
| Emulsion-fluid hybrid | A light oil phase suspended in water | Slip and comfort without the weight of a cream |
| Two-chamber or mix-at-use | Separated phases until activation | Actives that cannot hold a shelf life in solution |

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.
Questions we answer on every serum brief
Can you really fade dark circles?
Honesty converts: pigment-look and vascular-look respond to actives; structural shadowing does not. We word claims inside that envelope and reviews reward it.
Is it safe for contact lens wearers?
Yes with our fragrance-free base; ophthalmologist review is part of the standard documentation.
Morning or night?
Both work — morning pairs with the cooling applicator demo; we supply routine graphics for either position.
What you can change on this build
- Ceramic-tip or metal-roller applicators
- Ophthalmologist-reviewed ingredient screening
- Claims wording review for eye-zone compliance
- Before/after protocol under D65 lighting
