CLC 20-410 Smooth PP Treatment Pump, 0.25cc Dosage with External Spring Design

What this packaging is

An external spring design sets this treatment pump apart — the spring sits in a dry chamber, completely outside the liquid flow path, eliminating corrosion and contamination risks from reactive formulas like vitamin C serums and AHAs. The 20-410 Smooth PP Treatment Pump delivers a precise 0.25cc dose per actuation, built from durable polypropylene with a multi-layer construction engineered for leak prevention. With a 20mm neck diameter and 410 finish, it integrates cleanly with standard serum and moisturizer bottles. For brands formulating active skincare, this pump protects formula integrity while delivering a consistent, controlled application experience.

Why brands choose this

• Formula-safe engineering for active ingredients: The external spring sits in a dry chamber with zero contact with the formula inside — a critical design feature for brands working with vitamin C, AHAs, or other reactive actives that corrode standard metal springs and compromise formula integrity over time.
• Precision dosing that supports consistent skincare rituals: A fixed 0.25cc output per actuation removes guesswork at the point of use, helping consumers apply the right amount every time — a meaningful brand advantage in the serum and treatment moisturizer space where clinical efficacy and dose accuracy are increasingly front-of-mind for consumers.
• Multi-layer leak prevention for supply chain confidence: The multi-layer construction is engineered specifically to prevent leakage, reducing the risk of product loss or contamination during shipping, warehousing, and retail — a practical win for brands managing fulfillment at scale or working with higher-cost active formulations.
