I have sensitive atopic skin! This type of eye serum is the first one I've tried, and I generally liked it! The amount of serum that comes out with a single press is more than I expected, so it's good for applying over a wide area. The metal ball is cool, so there's a refreshing cooling effect as well! The massaging effect feels cool and nice, so even after applying the entire serum, I find myself rolling it on compulsively. The formula itself also has a cool, refreshing feel, so I was worried it might irritate my atopic skin, but it was fine. I'll have to wait and see on the wrinkle improvement effect.

There is a slight Hwahae-like feeling to it. So it may be stimulating for very sensitive people! It has a slightly stinging sensation, but it doesn't make your eyes water. You need to roll on the Steelball and apply it, so if you build up the base beforehand, it will spread.

Apply it in the basic first step! Since it gets quite a bit on the steel ball, wipe it off with something like a kitchen towel, not a tissue.

I've been using the product for a little over 2 weeks and it seems like there are no major downsides! Now that I'm a bit older, the wrinkles around my eyes and nasolabial folds have been a huge concern, so I've been doing face yoga as the final step in my skincare routine. After receiving this product, I've found that just rolling it on the eye area and nasolabial folds is enough to do the face yoga, and it's been incredibly convenient. The product contains peptides, so there's a plumping and firming effect on the wrinkles, which I really love! The ingredients are some of my personal favorites, and I really enjoy the rolling motion. I'd recommend this to anyone who does face yoga or is concerned about eye wrinkles and nasolabial folds - you won't regret it! I plan to continue using this product consistently. There's no irritation or breakouts on my skin. However, for those with very sensitive skin, it might be a good idea to do a patch test on your wrist or arm first, just to be safe.

The capacity is a bit disappointing. It would have been better if it were larger.

In the final step of your skincare routine, use this product to roll on the crow's feet and eye area, and then finish by applying a cream to cover it all! This product itself has an essence-like cream, so I use this product before applying the moisturizing cream as the final step.
