This line is a little more expensive but worth every penny for the results. You see better results faster than other less expensive products. I am on my second year of using this product and this will be a staple for the rest of my life. I’d rather pay a little bit more than purchase products that aren’t effective and don’t give maximum results. I’ve tried many Korean skin care brands and this tops them all the serum gives you so much so you don’t have to buy multiple products.
