Hello,
We are interested in a brightening vitamin C serum for our beauty brand. Can you provide a breakdown of the vitamin C concentration and any additional brightening agents in your serum?
The quantity will be directly shared to the reliable supplier.
How do you ensure the stability of these ingredients? Regarding quantity, what is the MOQ, and are there any volume-based discounts? We are also interested in learning about the available sizes and any customization options for packaging and design.
Best regards,
Sandra Martins
