To be precise, it's 3.5 stars. This wrinkle-reducing serum contains niacinamide. It can be used on the eyes, mouth, and forehead, and its thick texture creates a film like plastic wrap when applied. It spreads easily and provides strong moisturizing. One pearl-sized amount per area is a lot, so for the size of my face, one pearl-sized amount would be enough for all areas. It improves the quality of elastin, which is related to skin elasticity, while repairing wrinkles with the wrinkle-reducing ingredient niacinamide. I feel like my wrinkles are thinner the next day. I plan to repurchase.

Recently, I've been struggling with a string of unsuccessful eye creams, and the dark circles under my left eye have become increasingly hollow, leaving me with a gaunt, haggard look. So, I repurchased FANCL's Signs Effector, which was the most effective product I've ever used! The last time I used it, I wasn't sure if it was the product itself, but it caused some blemishes and I stopped using it. This time, I carefully tested the sample about three times before purchasing it. The texture of this product is thick and I really like it. FANCL promotes niacinamide, but other eye care products containing niacinamide tend to be more refreshing and leave me feeling unsatisfied. In that respect, this product stands out. The results were clear within three days. The hollows under my left eye became shallower and my wrinkles became less noticeable. Signs Effector is truly impressive... I'm changing my review. It was a very effective product. However, my skin seems to develop blemishes when I apply niacinamide, so I reluctantly stopped using it. It really does reduce wrinkles, so it's a shame about the pimples. However, if you can tolerate niacinamide, I highly recommend this eye cream, as it's thick and viscous, moisturizing, and even eliminates wrinkles! ----------- Past reviews: This is the most amazing thing I've ever seen...apparently. It's by far the best eye care product...apparently. I say "apparently" because it's still hard to tell after just two weeks of use, so I'm monitoring the results with Shiseido's Hada Pasha, and the wrinkled areas (the huge wrinkles under my eyes) that showed up in the wrinkle diagnosis have completely disappeared. This is an amazing thing for me...but I think Hada Pasha's diagnosis is pretty honest, so I'm stunned. Eye cream really works... Because it's sticky, I apply Fancl's wrinkle cream when wearing makeup. It's worth the price. Everyone, check it out with your skin diagnosis!
I bought this product hoping it would improve wrinkles under my eyes. I felt a slight itch under my eyes immediately after applying it, but I thought it was just my imagination and went to bed. I ignored the itch and used it a couple of times, but then I developed a rash under my eyes. I've used other companies' niacinamide serums for sensitive skin without any problems, but this one didn't seem to work well for me.
This was amazing. I'm used to seeing results from eye creams, but this one was by far the best at eliminating fine lines! It really smoothed out the fine lines around my eyes and mouth. I have a lot of fine lines, so my foundation crumbles and gets stuck in the grooves, making them look really bad, but this doesn't happen. It goes on so well and keeps my makeup moisturized, so my skin feels amazing! It was so good I ripped the package open with scissors and wiped it all down! It's a great wrinkle-reducing serum, and I'll definitely be buying it again!!! However, perhaps because the cream is too thick... If it gets in my eyes, it blurs my vision and clouds my contacts, so I'm hesitant to repurchase. I try to use it as thinly as possible and avoid applying it around my eyes, but even so, it still gets into my eyes when I blink and my vision becomes blurry. It's especially annoying that it clouds my contact lenses. I have hard contact lenses, and even scrubbing them can be difficult, so contact lens wearers need to be careful. But if you ignore that, it's a really good serum.
