The plumping effect is similar to how lips swell after eating spicy food. The ingredient 'Vanillyl Butyl Ether' creates a warming tingling sensation, which expands blood vessels, increases blood flow, and adds volume to the lips. Additionally, the menthol’s cooling effect works in cycles, promoting blood circulation and temporarily plumping the lips for added volume.

The warming tingling sensation on your lips is caused by the 'Vanillyl Butyl Ether' ingredient, which aids in plumping. This sensation may vary depending on your individual sensitivity and skin condition. If you have sensitive lips or existing lip injuries, please exercise caution when using this product.

The tingling sensation is due to the 'Vanillyl Butyl Ether' ingredient. While this ingredient is harmless if it enters your mouth, it may cause irritation. It's best to avoid getting the product in your mouth, but if this happens, the sensation should subside quickly.
