Serum pump closure with 20mm neck size.
Serum Pumps are designed to handle a thicker liquid product. The nozzle has a cleaner finish and can be associated with products designed for cream-based solutions. A cream pump will also come with a cap. This keeps the contents fresh and free from bacterial or product hardening problems around the centre hole.
Also available only in white.
Please Note: We recommend that these serum pumps be used with water based serums (serums with more water than oil) instead of oil based serums (serums with more oil than water) as the latter tends to leak a little during storage.
