Have a lot of advice!! Because the old kruidvat lash booster serum was such a big hit, it's been reformulated and back on the shelves!! I'm super happy about this. The old serum worked super well and all at the price of 9.99. The new serum maintains the same price and is vegan. Now see if it works as well as the old one. Here for the interested one a photo of the ingredients list of the old serum and the new variant! (Old serum left and new formula on the right)
