I’ve used Saranghae after I purchased the first box in November. It’s February and I still have a little bit of all the products left. I’ve ordered my second set and this time added the new charcoal pore reducing mask as well. I absolutely LOVE every one of these products. So after 3 months of daily use, my skin has improved tremendously since I switched from a 25 year loyalty to Shiseido products. I am 45 years old and have always used a good system (cleanser, toner, moisturizer) so have kept pretty good skin. Or I thought! This system is so lovely I would recommend it to any of my friends. The clear masks (6 per box) honestly are my favorite!!! I used my last one last night and when I was done with my face, I used it across my neck since these are so moist. My face is so smooth as is my neck. In 3 months, my face has had a reduction of age spots , redness and uneven tone, my face is firmer, wrinkles reduced, and just a younger glow! Thanks Saranghae for helping me feel beautiful again.
