I saw immediate results with this skin care set! My skin feels so smooth and soft after the first use! I use it every night and I am very satisfied with the results every time. Even though I am it is on the expensive side of the price, I think it was worth the money. The bottle of the first essence is glass and I think the ampoule is also. Doing the seven layer skincare with the first essence makes my skin feel like the mochi-texture. It helps prep my skin well if I use it in the morning before makeup. I highly recommend it to those who wants to put an investment in a good high-end skin care!
