I got my slin about two months ago and I've been using it on/off....
The expiry date on the bottle is AL 2006. I've been keeping it in the fridge the whole time. Lately I've noticed a lot of air bubbles in the vial. Why do most people say to throw it out after 1 month, when the exp. date on my bottle is 2006? Should I keep using it or get a new bottle?
