Commercial office: Guangzhou Yanse Cosmetics Co., Ltd. MOQ from 3,000 units per SKU for standard serums (3,000 bottles); 5,000 units per SKU for custom projects.

Azelaic serum projects,defined by the formula.
Private-label azelaic or azelaic-derivative serum development by YANSE COS. Confirm exact INCI, concentration, formula readiness, packaging, MOQ and sample schedule for your project. YANSE COS serum MOQ is 3,000 bottles per standard SKU and 5,000 bottles for custom formula projects. The bottle is the order unit; fill volume, container, closure and decoration are agreed in the quotation. Airless components, special packaging and multi-component ampoule projects may have separate minimums.
Free azelaic acid and PAD are different briefs.
Specify the exact INCI and concentration basis before comparing samples. Potassium azeloyl diglycinate (PAD) is an azelaic derivative; a PAD percentage is not a free-azelaic-acid percentage. Niacinamide and other formula partners must be identified separately.
Formula readiness, availability, use level and cosmetic positioning depend on the selected project. Request an approved formula, raw-material identity, final-pack stability and support for the claims you intend to use.
Three project briefs to discuss.
The references below describe development directions. They do not confirm inventory, a fixed active percentage or a dispatch date. Approve the selected formula and sample specification with the OEM team.
Niacinamide pairing
Discuss a serum with niacinamide and an identified azelaic ingredient. Agree the INCI, concentration basis, texture and pH.
- IdentityExact INCI agreed
