Sourcing a 30ml vitamin C serum for your own brand raises one question before all others: what does it really cost? This guide breaks down the complete OEM cost structure for a 10% pure vitamin C serum — ingredients, packaging, MOQ tiers, certification, and logistics — using the Private Label 10% Pure Vitamin C Serum from Lanthome as a working example. By the end, you will know where each part of your unit price comes from and how to protect your margin before you sign an order.
Key takeaway: A 30ml 10% vitamin C serum is priced at approximately $1.45–$2.50 per unit depending on order volume, with sensitive-active packaging and antioxidant ingredient selection representing the two largest cost drivers. Sample MOQs can start at a single unit, while custom production MOQs and volume discounts are quoted on inquiry.
Not all serums cost the same to make, and vitamin C serums sit at the more expensive end of the spectrum. The reason is the active itself. L-ascorbic acid — the pure form of vitamin C — is an effective antioxidant commonly used in skincare, but it is also one of the most challenging actives to formulate and package.
Three factors push vitamin C serum costs above a standard hydration serum:
According to a widely cited review of topical vitamin C in the Journal of Clinical and Aesthetic Dermatology, concentrations of 8–20% are the range most commonly studied in dermatological literature, with formulation pH and packaging identified as critical to maintaining activity. This is why a 10% formulation is a sensible, market-standard target — and why its cost structure deserves close attention from brand buyers.
A typical 10% vitamin C serum formula contains more than vitamin C alone. The Lanthome 10% Pure Vitamin C Serum lists pure vitamin C, salicylic acid, glycerin, and hyaluronic acid in its formula, which is a representative cost profile for this product type.
| Ingredient | Role in Formula | Relative Cost Weight |
|---|---|---|
| 10% pure vitamin C (ascorbic acid) | Primary antioxidant active | Highest |
| Hyaluronic acid | Hydration support | Low–medium |
| Glycerin | Humectant and base | Low |
| Salicylic acid | Exfoliation support | Low |
| Water, chelators, preservatives, pH adjusters | Vehicle and stability | Low |
Ascorbic acid is the dominant raw-material cost in this formula. Pricing for cosmetic-grade ascorbic acid powder fluctuates with global supply, and buyers should ask suppliers for current per-kilogram pricing when comparing quotes. A useful negotiating fact: derivatives such as ascorbyl glucoside or ascorbic acid esters are sometimes used in place of pure ascorbic acid because they are more stable, though they deliver vitamin C activity differently and change the formula's pH and feel.
The Cosmetic Ingredient Review has assessed ascorbic acid and its derivatives and concluded that these ingredients are safe in the present practices of use and concentration in cosmetics. For brand buyers, this means the active is well established — the cost question is about grade, sourcing, and stability strategy, not regulatory uncertainty.
Packaging is the second-largest cost driver for vitamin C serums, and the reason is functional, not cosmetic. Light, heat, and oxygen accelerate ascorbic acid degradation, so the container system does real preservation work.
Common packaging options for a 30ml serum and their cost implications:
For the Lanthome product, single package dimensions are 10 × 8 × 5 cm with a gross weight of 0.150 kg. That compact footprint matters for two reasons: it keeps per-unit freight low, and it makes the product efficient to warehouse and ship. When comparing supplier quotes, ask for the packed weight and dimensions, not just the bottle size — logistics is priced on the packed unit.
Real market data helps anchor expectations. The Lanthome 10% Pure Vitamin C Serum is listed at $1.96 per 30ml unit on the product page, with a note that the supplier's related vitamin C anti-aging serum set is offered at $1.45–$1.99 per piece at a 100-piece MOQ on Alibaba.com. These numbers illustrate a typical price curve: unit price falls as order volume rises.
| Order Scenario | Typical Unit Price Range | Notes |
|---|---|---|
| Single sample (1 pc) | ~$1.96 | Product-page listing price; sample MOQ is 1 pc |
| Small batch (~100 pcs) | ~$1.45–$1.99 | Comparable vitamin C serum set reference price |
| Mid volume (500–1,000 pcs) | Quote on inquiry | Volume discounts apply |
| Full production (1,000+ pcs) | Quote on inquiry | Custom MOQ negotiated with supplier |
Use these figures as a planning baseline, not a final price. Every quote depends on formula adjustments, packaging choices, label design, and destination. The Lanthome team states that discounts depend on order quantity — the more you order, the more discount is available — so it always pays to request tiered pricing before committing.
Minimum order quantities determine your cash outlay and your unit economics. The product page is explicit about the options:
The pricing logic behind tiers is straightforward: fixed costs — formula development, tooling, label plates, quality documentation — are spread across more units as volume grows. A 1,000-unit order will carry a meaningfully lower per-unit price than a 100-unit order because those fixed costs are amortized. Ask your supplier for a three-tier quote (small, medium, large) so you can see the discount curve explicitly and plan your first production run accordingly.
Private label and OEM projects rarely order a straight stock product. The Lanthome service menu includes one-stop OEM/ODM/OBM service, free design support, rapid proofing, and marketing support such as product materials and model resources. Each customization choice moves the unit price:
| Customization | Cost Impact | Notes |
|---|---|---|
| Label and logo design | Low | Free design service typically included |
| Formula adjustment (active %, texture) | Medium | Requires formulation and stability re-testing |
| Packaging swap (airless pump, custom bottle) | Medium–high | Component costs change significantly |
| Fragrance or color adjustment | Low–medium | Small-batch compounding cost |
| Carton and insert printing | Low–medium | Custom printing scales with volume |
A practical rule: freeze your formula and packaging specifications before requesting final quotes. Every revision during production adds cost and lead time. Confirm what is included in the quote — label design, stability testing, COA — so there are no surprises in the final invoice.
Certification is often assumed to be free, but it is a real line item that suppliers price into the unit. The Lanthome factory holds ISO22716 (cosmetic GMP) and GMP certifications, and offers BSCI, SGS, Intertek, CE, COA, and MSDS documentation services according to buyer needs. For a vitamin C serum, the two most relevant technical documents are:
Because ascorbic acid is oxidation-prone, stability data is more important for vitamin C products than for most other serums. Ask your supplier who covers the cost of stability testing at your MOQ level, and whether certificates are included in the unit price or billed separately. The same question applies to destination-market labeling: for example, the FDA's cosmetics labeling guidance requires an identity statement, net quantity, ingredient declaration, and manufacturer information on cosmetic labels sold in the US — confirm your supplier can produce compliant labels for your target markets.
Two practical details complete the cost picture: delivery time and payment terms.
The Lanthome product page states that in-stock items ship within 7 days, while production orders take 9–21 working days after payment. That range matters for cash flow planning — if you need inventory for a seasonal launch, book production time accordingly.
Payment terms offered include T/T, PayPal, Western Union, bank transfer, and Ali Trade Assurance. Trade Assurance adds buyer protection on eligible orders, which can be worth more than a small price difference when working with a new supplier. The company also transacts in RMB, USD, HKD, EUR, and GBP, removing currency friction for buyers in most regions.
Freight is the final variable. At 0.150 kg and 10 × 8 × 5 cm per unit, a 1,000-unit order weighs roughly 150 kg — well suited to air freight for speed or sea freight for cost at larger volumes. Get a delivered-duty estimate (not just an FOB price) before finalizing your margin model.
With an OEM unit price baseline in hand, you can model retail margins. The figures below are illustrative planning scenarios based on the price data on the product page — your actual landed cost depends on freight, duties, and customization.
| Scenario | OEM Unit Cost | Landed Cost (est.) | Retail Price | Gross Margin |
|---|---|---|---|---|
| Value positioning | $1.60 | $2.60 | $9.90 | ~74% |
| Mid-market | $1.80 | $2.90 | $19.90 | ~85% |
| Premium (airless pump) | $2.40 | $3.60 | $29.90 | ~88% |
Even at value pricing, a 30ml vitamin C serum can support healthy gross margins after marketing and fulfillment costs. The margin math works best when you lock in a volume tier, standardize packaging, and plan freight in advance — the levers covered in the next section.
The sample MOQ is a single unit, so evaluation is inexpensive. Production investment depends on your chosen MOQ, packaging, and customization; request tiered quotes to size the minimum order for your budget.
Generally yes. Ascorbic acid sourcing, low-pH formulation, and protective packaging all cost more than a standard hydration or niacinamide formula. The premium is modest at scale but visible in unit price.
The active degrades with light and oxygen exposure, so amber or opaque containers and airtight closures are functionally necessary, not just cosmetic. Component costs for these systems are higher than for clear bottles.
It depends on the supplier and MOQ. Lanthome offers certification services such as BSCI, SGS, Intertek, CE, COA, and MSDS according to your needs — confirm in writing whether certificates are bundled or billed separately.
In-stock items ship within about 7 days; production orders take 9–21 working days after payment, depending on volume and season.
Yes. Per the supplier's stated policy, larger orders receive larger discounts — request a three-tier quote to see the curve before committing.
