GET PUMPED

We’re always looking to make things better, so we’ve upgraded the packaging for our full-sized No. 1 Serum to a sealed, easy-to-use pump.
Vitamin C PreservationWe use THD, a stabilized form of Vitamin C, and limit added preservatives. This pump helps preserve the Vitamin C even longer and protect it from oxidation.
Perfect AmountThe No.1 Serum is packed with rich seed oils and hyaluronic acid—a little goes a long way. This pump dispenses the perfect amount.
Stays FresherLarger product sizes take longer to use, so reducing air exposure over time is more important. Using a pump rather than a dropper helps keep your Serum fresh.
