What's the best way to keep the pumps from clogging? I've been thru two full-size bottles of super serum and both get clogged after the first few days and start spraying serum in all sorts of entertaining directions.

Have you ordered serums recently? SN has changed out the pumps (they're white now) and are amazing! So much easier to work with and it does not clog! I have two serums that have the new pump. I totally hear you on the old pumps....mine would get clogged (the vitamin c serum) and I would end up opening the bottle and pouring however much serum I needed.

I think it was mid-September for my last order.

Agreed the old black pumps i find clogging!! The new White pumps i find to be just ok it doesn;t clog but it pumps out alot of product!

I must use a lot of product then cause I find the white pumps to dispense the right amount of serum for me! Sometimes I go with two pumps
