Private Label Serum Capsules: How to Spec a Single-Dose Skincare Line

How to scope a private label serum capsule line: the six fields that make quotes comparable, count and dose formats, and how capsules differ from bottled serum.

What should a buyer confirm before ordering private label serum capsules?

Six facts carry the whole specification: the count per box, the dose volume, the carrier formula, the listed skin types, the listed functions, and the labelling language. Get those six in writing and a capsule line is scoped. Skip them and every quote you receive will describe a different product.
A capsule is not a smaller bottle. It is a dose format, and that changes what you are buying.

Why the capsule format changes the sourcing conversation

Most skincare sourcing conversations start with the formula. Capsules move the conversation one step earlier, to the dose.

Dose size is the specification

A capsule line is defined by how much product each unit holds and how many units sit in a box. Those two numbers set your cost per use, your shelf presence, and your reorder cadence. When a supplier quotes a capsule product, the count and the volume are the two fields that determine whether two quotes are even comparable.
ZONO's current capsule range spans four counts and two dose volumes:
| Format | Count per box | Dose |
|---|---|---|
| L-Ascorbic Vitamin C essence capsules | 50 | single-dose capsule |
| Vitamin E serum capsules | 60 | single-dose capsule |
| Rose concentrated essence oil capsules | 60 | single-dose capsule |
| Fullerene anti-aging essence capsules | 30 | single-dose capsule |
| Vitamin hair care essence capsules | 40 per bottle | 1 ml standard; a 0.5 ml variant is also available |

The count sets the price ladder

Two boxes that hold the same formula but a different count are two different products to a buyer's customer. A 30-count box and a 60-count box can sit at two price points without reformulating anything. That is the cheapest line extension available to a capsule brand, and it is decided at the spec stage rather than the formula stage.
The L-Ascorbic range makes the point concretely: a 50-count box is the standard pack, and a 40-count box is also supplied. Same capsule, two entry points.

How to compare capsule suppliers on facts, not adjectives

The four fields that carry a capsule listing

When you compare capsule options, compare these four — not the product name.
1. Count and dose. How many capsules per box, and how much each holds.
2. Listed skin or hair types. Which conditions the supplier's documentation actually names.
3. Listed functions. What the label claims, in the supplier's own wording.
4. Labelling language. Which market the printed packaging is prepared for.
For example, the Vitamin E capsules are listed for neutral, general, oily and dry skin with moisturizing and anti-wrinkle as the listed functions, under English labelling. The Rose oil capsules are listed for oily and dry skin and name four botanicals on the label — rose flower extract, olive fruit oil, centella asiatica root extract and ginseng root extract. Those are specific, checkable facts. "Premium quality capsules" is not.

Ask for the ingredient list before you commit

An ingredient list is available on request for ZONO's L-Ascorbic capsules, and that pattern is worth applying across any capsule line. If your market needs a documented formula, request the list before ordering rather than after. A capsule that photographs well tells you nothing about what is inside it.

What is actually in ZONO's capsule range today

ZONO coordinates private label and OEM/ODM cosmetic projects from Shantou, Guangdong, and our current capsule range covers four skincare counts and one hair care format:
- L-Ascorbic Vitamin C — 50-count (40-count also supplied), listed for neutral, oily, dry, sensitive and combination skin, with moisturizing, hydrating and brightening as the listed functions. English labelling, 3-year shelf life.
- Vitamin E — 60-count, with vitamin E and panax ginseng named on the label. Listed for neutral, general, oily and dry skin, functions moisturizing and anti-wrinkle. English packaging, 3-year shelf life.
- Rose concentrated essence oil — 60-count, listing rose flower extract, olive fruit oil, centella asiatica root extract and ginseng root extract. Listed for oily and dry skin, functions moisturizing and anti-wrinkle.
- Fullerene anti-aging — 30-count.
- Vitamin hair care — 40 capsules of 1 ml per bottle, with a 0.5 ml variant available. Plant oils listed include olive fruit, jojoba seed, sweet almond and camellia japonica seed, alongside panax ginseng extract, vitamins A, C and E, and pro-vitamin B5. Listed for dry and damaged hair, with a light non-greasy feel. English labelling.
Our ready-stock path starts from 12 pcs with dispatch in 48 hours for in-stock items, and we run three routes depending on how much of the product you want to control: ready stock, semi-custom, and full OEM/ODM.

Serum capsules or bottled serum — which does your line need?

These are two formats with two different SERPs and two different buying behaviours, and it is worth deciding deliberately rather than by default.
Choose capsules when: you want a fixed dose your customer cannot over-apply, a travel-friendly unit, or a count-based price ladder you can extend without reformulating. Capsules also suit single-use hygiene stories and gift or trial formats.
Choose a bottled serum when: your positioning depends on a texture the user dispenses themselves, a pump or dropper presentation, or a volume-led value message (30 ml, 100 ml). A bottle gives you a larger visible fill for the same shelf slot.
ZONO supplies both: the capsule range above, plus bottled essences including a 30 ml arbutin and vitamin C essence and a 100 ml ginseng gold serum available in glass or plastic. The two formats are separate sourcing decisions, and we scope them separately so your capsule line does not compete with your bottle line.

Frequently Asked Questions

Can I order a capsule line in a small first run?

Our ready-stock path starts from 12 pcs, with dispatch in 48 hours for in-stock items. For custom configuration, tell us the count, the dose and the packaging direction that still need confirmation and we will come back with the route that fits your first run.

Can the count per box be changed?

Count is the field that defines a capsule product, so it is the first thing worth discussing. Our current range covers 30, 40, 50 and 60 counts, and the L-Ascorbic line already ships in both a 50-count and a 40-count box.

Is the ingredient list available before ordering?

Yes — for the L-Ascorbic capsules the ingredient list is available on request before ordering. If your market requires a documented formula, ask at the quoting stage so the information arrives before you commit.

Which skin types can a capsule line be listed for?

It depends on the formula. Our current capsules name conditions on the label rather than implying universal suitability: the L-Ascorbic range lists neutral, oily, dry, sensitive and combination; the Vitamin E range lists neutral, general, oily and dry; the Rose oil range lists oily and dry. Confirm the conditions your target market needs and we will match the formula direction to them.

How long does a capsule product last?

Shelf life is documented per product — our L-Ascorbic, Vitamin E and Rose oil capsules each carry a 3-year shelf life. Confirm shelf life for the specific formula and storage conditions you are planning.

Do you provide certifications?

Certification scope depends on the product and the destination market, and documentation is available upon request for the specific project. Final compliance and labelling responsibility stays with the brand owner or your appointed responsible person in the target market.

Can capsules be private labelled with our branding?

Yes. ZONO is a private-label and OEM/ODM cosmetics partner, and packaging, logo and outer-box directions can be reviewed for the selected configuration. Share your artwork and the packaging direction you want and we will confirm what is workable for the format.

Conclusion

A capsule line is scoped by six fields: count, dose, formula direction, listed skin types, listed functions and labelling language. Confirm those and quotes become comparable. Decide capsules versus bottles deliberately, because they are two different products to your customer.
