How to use
Use at the end of your morning and evening skincare routine. If you use cream, use this product afterwards. Apply an appropriate amount to areas where wrinkles are a concern, such as around the eyes and mouth. A rough guideline is to use about the size of a grain of rice around each eye.

It's not too watery, not too thick, and has just the right texture, making it very easy to use. The texture is just right, so it's easy to apply to any part of your face! I love that it doesn't smudge even when you're wearing makeup, so I can use it in the morning too! I'd like to continue using it and see the results!
It was on sale online at KOSE, so I bought it for the first time in a while (it's been a while since I've used an eye cream in general). It's been a while since I used it, but I feel like the dry wrinkles at the corners of my eyes and the laugh lines on my lower eyelids, which had been bothering me, have become a little plumper and better!! It works better on my eyes as a woman in her 40s than on my mid-30s. It seems to have been renewed, so if I buy it again, I'll try the new one. It's pretty good! ※※Previous review below※※I bought it from the KOSE online shop. I'm almost finished with one bottle, but I'll be happy if I can continue to use it and maintain the same level of effectiveness. It doesn't smudge even when applied before makeup in the morning, and it's moisturizing, so it's easy to use. I'm not sure if I'll buy it again...I have other products I'm interested in, so I'll compare it with those and see how it compares.
I noticed a reduction in wrinkles immediately after applying it, so I bought the large size. The thick, spreadable texture makes it easy to use. Although it hasn't dramatically improved my skin, I also use it to prevent wrinkles on my forehead and around my mouth.
I have bought this product more than three times. I have tried other products, but this one is the one that suits me best. It's not sticky but moisturizes, and I feel like it's effective. It's a product I will continue to use.
I was concerned about hollows and lack of firmness around my eyes, so a friend recommended this product to me. It's a rich, thick orange cream. It blends easily into the skin, and from the moment I applied it, it left my skin feeling elastic, like it had been coated with a film. The penetration-promoting capsules supposedly work deep into the stratum corneum, leaving it feeling deeply moisturized. I felt even better results when I used it after thoroughly moisturizing with lotion.
