I won a giveaway from Suzykirei and received this (^^) Thank you Suzykirei and Takami! I've just finished one bottle, so I'll write a review. I've used the introductory serum many times, but this was my first time using this. It has a light texture, but it feels like it soaks into the skin quickly. I have dry skin, so I thought it might be a little lacking in the winter, but in the morning my skin felt smooth and my skin texture was refined. I think it would be good for people with dry skin to combine it with a moisturizing cream in the winter.
