1. Maintains Product Integrity

• Prevents Oxidation: For products containing active ingredients like vitamins (A, C, E), retinoids, or certain essential oils, exposure to air can degrade their potency. A locked pump creates a better seal, minimizing air from entering the container and prolonging the product's shelf life and effectiveness.

2. Improves User Experience and Confidence

• Peace of Mind: Users can throw the bottle into a bag without a second thought. This confidence is a huge plus for products designed for on-the-go use (e.g., hand sanitizer, travel-sized toiletries, sunscreen).

• Clear User Feedback: The audible "click" and physical resistance when locking/unlocking provide clear tactile feedback that the pump is secure.
