I've always had some redness to my skin--mostly my cheeks and nose. Using this every night for months, going through 1 and half bottles, I've finally seen quite a bit of improvement. The redness isn't completely gone, but I didn't expect it to be. I highly recommend this, if you have patience--don't expect miracles, and don't look for immediate results. If you're worried about the size/quantity (it's 1/2 oz) for the money, don't be; I only need to use about 1/3 of a pump because it's so concentrated and spreads pretty easily. I haven't found any other product that has a lot of Vit K (which is what helps the redness) for less money, so I'll be sticking with this one.

This under eye cream didn't work miracles but it helped improve the darkness under my eyes

I've been using the Vita K for about 6 months now and have noticed a subtle reduction in redness caused by my rosacea, as well as some post-inflammatory redness from acne. As the title suggests, you're not going to see some dramatic improvement in a matter of days or even the first few weeks. I intend to continue to use Vita K as part of my overall skincare routine.

This product is very hydrating and feels great under my eyes but I have not noticed a difference in my dark under eye circles, which is why I bought it. I won't purchase it again.

I bought this based on reviews saying it helped with redness AND dark circles while also keeping their skin hydrated. I think it's very tricky for one product to treat both of those issues, but I had to try it out for myself in hopes it would. I don't mind that the product comes out yellow and the scent doesn't bother me or anything, but the texture didn't feel hydrating at all. The description says "weightless serum" so I was expecting more of a runny consistency, so maybe this shouldn't be considered a serum (unless something is wrong with mine). When I used it, it made my skin even drier that what it was before! And it actually exaggerated my under eye dark circles, especially my right eye, which is really strange. It's like it made it all worse. So I don't understand if mine is defective, expired, or it is just very wrong for me and my skin??? It just made my skin feel stiff and weird. I would not recommend for dry skin.

I have rosacea and my skin is on the dryer side, this somehow both calmed the redness and also hydrated my skin at the same time. Love love love!

I bought this to treat dark circles. Vitamin K works great for dark circles. I haven't noticed a difference yet. The eye cream is very yellow which was unexpected. It goes on smooth.

I have genetic dark under eyes that are bluish purple. I've tried so many products that claim to help with dark circles, but do nothing. I've been using this nightly for a few weeks now and I can actually see a difference! I hope it keeps improving my dark circles because I do not want to resort to some kind of filler!

Glides smooth on to eye area and leaves a shine. Dark circles slowly lightening. I think this will work to help with dark circles

My esthetician recommended this product to me at my last appointment. I love this product; it's really helped to reduce the redness I experience!
