12.5+12.5ml / 15+15ml / 25+25ml Dual Wall Dual Chamber Double Pump Serum Bottle 0.25ml Fixed Dosage for Day & Night Skincare Packaging (Retinol & Vitamin C)(MC-1605)

Product Description

The Dual Wall Dual Chamber Double Pump Serum Bottle is an advanced cosmetic packaging system designed for modern skincare brands that require ingredient separation, dosage precision, and premium packaging aesthetics.

Unlike traditional single-chamber bottles, this structure integrates three functional systems:

· Dual Wall Structure (outer luxury protective shell) 

· Dual Chamber System (independent formula storage) 

· Double Pump System (separate dispensing control) 

Each pump delivers a fixed 0.25ml dosage, ensuring consistent application across users and improving formulation efficiency for brands.

This packaging is specifically engineered for day & night skincare systems, especially for active ingredients such as Retinol, Vitamin C, peptides, and brightening serums, which require separation due to oxidation sensitivity and instability.

It is widely adopted by premium skincare brands, OEM/ODM manufacturers, and Clean Beauty companies targeting US and European markets.
