Consistency is key. For those who find applying sunscreen a hassle or find it wears off quickly, just use this at night!

If only it were a bit cheaper... Oh, and if you try to make it last longer by using tiny amounts over a long period, it seems to oxidize. You need to clean around the opening well, as product builds up there and can harden at the tip!

This stuff is great. It's pricey, but it works. To be honest, I'm not usually a fan of department store brands. I often can't tell if they're really that much better. But this one's different! Apply it to your nasolabial folds and around your eyes, and after about a week, you can actually see the difference! When you feel like your fine lines are about to turn into deep wrinkles, use this and you'll notice visible improvement. Highly recommended! I've even repurchased it myself.

파워풀 비타민C 아이세럼

If there's ever a day when it's on sale at a good price, I'd recommend it for those with sensitive skin who want to try a vitamin C product but are worried about irritation.

I had no idea it would be this expensive... And the instant brightening effect? Well, that was due to the titanium dioxide, a physical sunscreen ingredient. Still, apart from the Calendula Toner, this is the second most appealing product from Kiehl's for me.

I tried a sample and was surprised by its slightly primer-like texture, which felt buttery and silky. Vitamin C products usually show effects on my skin the next day, and I figured it wouldn't be good to use for long after opening, so I applied it not just under my eyes but all over my face. Surprisingly, the next day there were no blemishes, and my skin seemed brighter with seemingly smaller pores. Even though I felt a warming sensation when applying, which made me think there would be irritation, there was absolutely none... What's going on?? When I saw it said to use in the morning too, I tried it, and it even had an immediate skin-improving effect. I was amazed thinking, 'This is incredible!' Definitely a product I'll consider using consistently.

While there's only one ingredient to be cautious about, it's still disappointing that there's even one. Also, it doesn't seem to have much effect on dark circles.

The pump dispenser makes it hygienic and convenient to use. I love that it's not too oily, so it applies smoothly around the eyes without leaving a greasy shine.

The price-to-volume ratio is a bit disappointing. However, I bought it last December and have been using it every night. Seeing that there's still some left after ten months, it doesn't feel overly expensive anymore!

It's not lightweight, but it absorbs well, so I've been using it consistently. As it's an eye cream, I can't say I've seen dramatic changes, but if my eye wrinkles haven't deepened since last year-end, I guess that's good enough, right?

1. Despite being called a serum, it has a cream-like texture. It feels a bit rich for oily skin, so I recommend applying it only at night.

2. Unlike typical serums that absorb quickly, this one feels like it both absorbs and coats the skin, leaving a slightly sticky finish.

1. The airless pump container is hygienic and easy to use.

2. I have oily skin, and usually, if I use the wrong eye cream, I get blemishes around my eyes. However, I've been using this without any issues.

3. It absorbs well.

There's nothing particularly disappointing, but I wish the product came in a larger size.

I love that it's not sticky. I've been applying it under my eyes and around my mouth, and I'm really satisfied with the results.

It causes a burning sensation and irritates the eyes, making them tear up. Using less product does reduce the irritation significantly.

While there doesn't seem to be much mention of the scent in Hwahae reviews, both I and other reviewers on Sephora have noticed a metallic smell. I'm not sure if it's just my product that has oxidized vitamin content or if this is normal. The strong metallic odor persists for hours after application, which I find too off-putting to continue using.

Considering all these drawbacks and the price, I hardly noticed any improvement in dark circles or wrinkles.

* Helps with blue dark circles and fine lines around the eyes
* 7-day sample from Sephora (actually lasts much longer)

Very hydrating. Only a small amount is needed for application.

I was startled by the intense burning sensation when I applied it

It feels so hydrating and plump, like it's really filling up my skin

When I first started using it, there was a slight tingling sensation, but I didn't experience any blemishes. As I continued to use it, the sensation subsided.

I've been using this for over two weeks because the skin around my eyes was so dark, and I've definitely noticed an improvement in my complexion. The vitamin C seems to be doing wonders for my skin health.

It's a bit thick, which might feel heavy on the skin. Keep this in mind before purchasing!

I absolutely love that it contains highly concentrated vitamin C!

It doesn't absorb well if you apply a hydrating essence first. For best results, apply it tightly after smoothing your skin texture, then follow up with a hydrating essence and cream to maintain moisture for a long-lasting dewy effect.

After application, there's a feeling of tightness that dissolves with rolling, and even after patting for a long time, a slight stickiness remains. While it doesn't cause makeup to lift, if you don't use a hydrating product afterwards, it might feel a bit dry later on.

Even with a tiny amount (about 1 pump), it absorbs beautifully, covering not just the eye area but also smile lines and neck wrinkles. After application, you can feel a slight warmth and a sensation of a protective barrier forming. Despite the short usage period, there's a sense that wrinkles have slightly faded.
