January 30, 2026: I'm raising my rating by one point. ★5 → ★6 Because the contents are hidden, it feels like it suddenly ran out, but it didn't get hard to get to the end and I was able to use it smoothly until the very end. Replacing the cartridge is also very simple. I wish everyone would use this method. After my dark circles disappeared and I found myself forgetting to use concealer, I decided to stop using them completely before finishing a bottle. And it even affected my under-eye bags! They didn't just disappear, but the dullness disappeared and I no longer noticed them. The results were better than I expected and I'm very happy. I was amazed that I was able to see the results after switching from Double Serum Eye. The new container makes it easier to use. I used one bottle in the old bottle, but the pump clogged up quickly, which was quite frustrating. I've finished using three of Clarins' most popular eye serums, all of which I can't throw away, so I'd like to compare them. Grand Eye Serum V: The ultimate firming product. My face gets extremely swollen during the rainy season and summer, and this product really helped. Probably a summer must-have. Double Serum Eye: A well-balanced, excellent product. It tightens the eye area, moisturizes, and has anti-aging properties, making it the easiest to use. I think I'll be buying it again in the spring and fall. Total Eye Intense: An eye serum for anti-aging care. It seems to have a tightening effect, but I didn't really notice it. However, it seems to be a high-spec item that provides moisturizing and eyelash care for the entire eye area. I haven't noticed any changes, but even though I have super dry skin, it's amazing that I can go through the dry season without feeling any dullness or dryness! It's refillable, easy to use, and cost-effective, so I feel like this is the one for the dry season!
