Another top from Korea!! I received this sample when ordering online. Again I notice the difference between skincare from Korea and the rest... On my face I applied this Collagen cream and on my neck the retinol cream from Paula's Choice. On my face I really felt something happening, it was really a powerful contraction and ultimately that resulted in glowy skin. I didn't feel anything happening on my neck... I am really impressed with this Collagen cream after first use and I am sure planning to buy the full-size variant. This is going to be a steady staple in my skincare routine.
