Nice

Nice eye cream that works very well at de puffing the eyes and smoothing fine lines

It’s okay

Kylie

Haven’t had amazing results unfortunately! Still good but nothing special whatsoever
  1. Great!

    Y

    being dehydrated and fighting age around the eye area, this is the best product I’ve tried. Highly recommended
  2. Didn't work for me

    Sasha

    I didn't notice any major improvements. The serum is quite greasy so I found I could only put it on at night. If it put it on and didn't go to sleep straight away it would make my eyes sting. Given the price, it did not do what I expected.

  4. Go ahead, do your eyes a favour

    I look younger. Seriously.

    After about a week and a half of using this I have seen a photo of myself and I look so much younger. The tired dark circles are slowly fading and it’s made such a difference to my overall appearance, I feel amazing. It’s a beautiful product and it’s made me very happy - worth the big bucks!
  5. Amazing

    Carlz

    I had to save so long to get this but omg worth it. I was at first disappointed at size BUT you need only the tiniest amount. Really helps with fine lines and just plumping due to moisture
  6. The best eye serum ever

    Karen

    verified purchaser
    The best and only eye serum I'll ever use! You really only need a tiny pin size blob to cover both eyes, and it somehow leaves your eyes hydrated and brightened. Great under make up. Great before bed. Great all the time, I love it to bits.
  7. Prettiest eye cream

    Rosie

    verified purchaser
    As the other reviews mention, the consistency is a bit sticky but once you work out how you like to apply it, you'll love it.
    It has helped with the appearance of fine lines and hereditary dark circles. My sensitive skin has no problems with this eye serum and I have not a reaction.
    Will be repurchasing.

    verified purchaser
    bought this eye cream after reading a post about how amazing it is. i can't say that it's resulted in any major improvements however, i don't really have any eye concerns at present and purchased it as a preventative measure. as for the serum itself - it is the prettiest eye serum i've ever seen! it is rather tacky, which i don't mind, but i find that for me, it's best suited to using at night rat...

  9. Amazing eye cream

    C

    This gorgeous eye cream is something else! So unbelievably good! Helped so much with puffiness and is also slightly softened my fine lines! Absolutely amazing
  10. LOVE

    Francesca

    I LOVE this eye cream. It feels tacky so needs a few minutes to absorb... but saying that it also feels extremely nourishing and hydrating which is exactly what I was after. Highly recommend this product. The only downside is the price point.
  11. Purple holographic eye serum

    Emi

    The serum comes out purple holographic which really surprised me. I imagine it must serve some light-reflecting purposes to brighten up the eye area. Non-irritating serum and has not caused any milia (my eye area is very sensitive) and fine for contact wearers (i wear contacts).

    Only a tiny little bit if recommended and I warm it up between my two ring fingers before tapping it on ge...

  12. Love love love

    Brigita

    I love this cream! It’s a small tube but lasted approx 4 months. Suits well if you have semi dry skin with mimic wrinkles around the eyes. Already purchased my second tube.
  13. Great under makeup

    CarleyP

    This eye cream is great, particularly under makeup. It’s very moisturising, yet not thick. It’s almost sticky but rubs into the skin well. I love the unicorn tear look it gives, it helps distract from my dark circles.
  14. LOVE!

    Danielle

    I adore this eye serum. I use it in the morning and found it has made a huge difference to my fine lines and darkness.
  15. What sorcery is this???

    Jenna

    I’m over 40 and I’m interested in results not gimmicks. I have been on a really disappointing journey to find an eye cream/serum to address fine lines, puffiness and loss of elasticity. I only bought this because I had tried pretty much everything else, was still searching, and the reviews were amazing. Everything about this eye serum screamed of hype and gimmicks. Except the results. I’m so happ...

  17. Amazingly Stunning Eye Cream

    Mikaela

    This is not only the most beautiful eye cream (holographic), it is also a great product. It has thick, glossy consistency and stays exactly where you put it. I put it on straight after I hope out of the shower in the morning, let it soak in for a few minutes and then cover my whole face with my daily SPF moisturizer. My eyes seem fresher and more hydrated when I'm using this. Would definitely purc...

  19. Tried a sample

    Freya

    I've sampled this one and it's incredible after one use! It's just so expensive for what it is. I think that a strong skincare routine with cheaper brands is a better option. That said, it does seem worth the investment. I'm on the fence with this one.
  20. Cosmedix Opti Crystal- Liquid Crystal Eye Serum

    Zhaowei

    Left my skin feeling a little dry so 100% not for night & for the price point, could probably find something better for day wear.
  21. Life changing

    Melissa

    This is amazing!! I use at night, only need the tiniest amount. My old eyes are more hydrated than they have ever been. I’m impressed. This has had more effect than anything I’ve ever used, including products costing a lot more. It’s a deep hydration that lasts as opposed to surface only. Don’t apply make up over as it will sink into lines
  22. Hydrated

    Anna

    Lasts for a long time and I do feel my skin hydrated after use. Can't say I've noticed long term effects, but have only been using for a month
  23. Worth the Investment

    Kimera

    Great eye serum - lasts a good 6+ months - and more importantly, it works! It is a slow-and-steady serum, with best results noticed with long-term consistent use, - but it has definitely addressed fine lines and because of it's beautiful 'unicorn tears' look, feels indulgent. I also love that this serum is very viscose, once on it doesn't budge; so it works great under creams, sunscreens, and con...

  24. A little goes a long way

    Mon

    Super hydrating and could see my under-eye area brightened with a few weeks of use. Dark circles are still there but easier to conceal because this product helps to moisturize, smooth and brighten the area
  25. defiantly spending the money on

    mia

    This product is very pricey, however that's expected with eye creams and honestly I've never spent my money on something better! I have very dry undereyes and eyelids and this product lived up to every one of my expectations and hydrated my eyes so much! I love it so much and it last for ages! definitely will be telling all my friends to buy it
  26. TINY

    Hannah

    I feel it is hard to judge just how good this product is as I was so annoyed by the size! I received bigger free samples with my order! Apart from the fact that it is not worth the money the texture actually does go on very nice and looks amazing when it comes out
    Have been using about every second day for over a month I haven’t seen drastic results yet but I am hopeful! You have to wear so...

  27. Amazing

    Kelly

    This is amazing! All you need a little drop and it’s enough for under both eyes. Love the textures and the feel!
  28. Helps with wrinkles and puffiness

    amy

    This serum is really sticky so I only use it at night. Hasn't helped with the dark circles but seems quite good for wrinkles and reducing puffiness. Not sure if I would buy again though.
  29. Love it

    Bee

    Definitely has improved my overall eye area . Looks brighter and healthier . Wish it wasn’t so exspensive but I guess you get what you pay for :)
  30. Unique product

    christine

    I love this serum for day use as it sits nicely under my make up and seems to illuminate the eye area somewhat. Its a cool opal/galaxy kinda colour! Pricey for such a small tube so I do tend to use it sparingly. I don't tend to use it all the time in winter as I require something more hydrating.
  31. Amazing all rounder serum - the tiny tube lasts forever!

    Sarah

    This serum is perfect as an all rounder - sometimes I have a bit of puffiness, darkness and of course a few wrinkles and this tackles the lot. You only need the tiniest amount so the tube lasts forever which makes the price tag justifiable. The texture is quite sticky which was different to other eye products I’ve used but it keeps it in place. Have been using this for over 2 years now and I’m not...

  32. Amazing

    Carly

    I got a sample of this from my beauty therapist and omg!! Exy but worth it...so beautiful under eyes and sits perfect under makeup. Nourishing and brightening. It’s on my list of treats at tax time!!
  33. Keeps my under eyes firm and hydrated

    Geo

    This does such a great job of reducing fine lines and dehydrated under eyes.
    I've noticed that this helps keep my under eyes plump and stops them from looking hollow. Although this seems expensive for such a small amount of product, it lasts so long because only the the tiniest amount is needed and I really think it's worth it.
  34. Wow

    Anita

    This has really made a difference after just 2 weeks, I.oressed!
  35. Perfect

    Lisa

    People will tell you it’s very thick and difficult to spread. That’s what makes it number one. Stays where you put it, doesn’t leak into your eye and mascara like cream. Dab it on in pinhead amounts. Tap it around and it spreads as it warms. Does what it says - fine lines yes, moisturises yes, dark circles to a degree.
  36. Amazing

    NICOLE

    I brought this product after reading some reviews highly recommend.Purchased more then 6 months ago I received it and started to use it straight away.
    Major difference after a week I noticed the fine , saggy lines under my eyes were almost gone and smoothed out.

  37. The holy grail of eye creams

    Mikki

    Overall I have combination skin (sometimes dry skin, but consistently oily through the t-zone and prone to hormonal breakouts around the jawline) . When I started using this product I was 27 and using no anti-aging products. I was shocked when I saw a photo of myself with swollen, saggy bags under my eyes with crows feet appearing.

    After doing a lot of research I decided to invest in ...

  38. Great products come with a price

    Marcella

    I was very sceptical about this at first, I purchased this based on some intense research and varying reviews and took a leap of faith that well and truly paid off. My biggest concern at the time of purchase was crepey eyelids and those pesky corner lines, after religiously using this in the am and pm I noticed a significant improvement in my eyelids and it most certainly helps with crows feet. I...

  39. Heavy and over priced

    Victoria

    It's hard to find an eye cream that does what it says. i don't think this cream really does much. And its very expensive. Its very sticky and I would only recommend on very aged skin or your eyes really puff up.
  40. Best eye cream ever

    Janelle

    While this is quite expensive, for me, it is worth every cent and you only need a tiny amount so it lasts a very long time. I use it at night only. It's ultra hydrating and helps with dark circles. No need for concealer with this in your daily skincare routine. I've tried many different eye creams in the past and this is the only one that I think actually does anything.
  41. My First Eye Product

    Lachie

    Not one for eye products, however, This product is amazing I love the way it changes the tone of my undereye area
  42. Don't believe the hype

    May

    This product came highly recommended to me by my facialist and as a fan and user of a number of Cosmedix products I was looking forward to trying this beauty out. I'm sorry to say nothing happened. Absolute zilch.

    It is a very pretty, shimmery blue colour with a not- unpleasant, sticky honey-like formula. My main concern is dark circles and sadly they remain! People do rave about it t...

  44. The Best eye cream i have ever used!!!

    Meike (Adore Beauty Staff)

    Finally I have found my ultimate eye cream that wont irritate my sensitive and reactive eye area and works!
    It is ultra hydrating and helps with dark circles and small lines! So if you have red patches and get irritated from most eye creams this is the one for you.
    Hot tip - USE SPARINGLY - it goes along way hence the size of the tube!
    I use it as night treatment and only in t...

  45. Not wowed

    Laura

    Not going to lie, I do expect miracles from my eye cream - I am extremely unrealistic. I bought this hoping it would diminish my puffiness, but I think I just have to accept that nothing will cure the puffiness until I stop drinking wine. But it does feel nice, and keeps the fine lines at bay, and sits really nicely under makeup.
  46. Amazing

  47. Drab to Fab

    Jessica

    This small package has big surprises! It's so fab. I have used a lot of different eye creams in the past and I wouldn't use anything else. My dermal clinician recommended this to me as I have a few smile creases around my eyes. This eye serum hydrates the skin around my eyes ever so gently. The texture is a little sticky but I find that works really well as it leaves this amazing glow around my ti...

  48. Great

    R.

    Good product, i use this every second night before bed. Its a thick wax-like texture but it smooths out when you rub between your fingers before applying. Really hydrates the undereye area
  49. Still unsure!

    Ash

    I’m still unsure about this product - have been using for 2 weeks now. It is kind of like a wax texture that you have to warm up in your fingers first to make it more spreadable. Even still, I feel like it drags on the skin. It says you only need a pin head sized amount, but I don’t think that covers the whole under eye area. I’m used to using a cream type of eye product. Maybe I’ll just have to g...

  50. Actually works

    Anne

    I have hereditary dark circles as well as fine lines under my eyes. This is the only product I've ever used which makes a visible difference. It successfully brightens and keeps my fine lines at bay.
  51. Beautiful

    Kylie

    You won’t understand the term unicorn tears until you get this eye cream. It reflects in rainbow pearl colours once applied. You only need a pin head sized amount. After a few weeks I really do think it’s helping to reduce my under eye fine lines. Will continue to use to see long term results.
  52. Still deciding!

    Gemma

    Not convinced of this one yet given the price. It feels great when it’s on but I’m not sure if I’ve noticed a change to the fine lines under my eyes.
  53. Highly recommend!

    Ash (Adore Beauty Staff)

    I have tried many eye treatments but this the first one that I’ve used that actually works.
    You only need a pin size amount but boy does it pack a punch. Its hydrating and plumps any fines lines.
    I've been though one tube which lasted a long time and on to my 2nd.
    It has holographic pigments which is best described as mermaid tears, ever so pretty.
    I would definitely rec...

  54. Best anti ageing eye product I've ever used

    Katherine

    This product has a cult following for a reason. It is such a great anti aging product and I believe it really helps to hold back the signs of aging in the eye area. It has lots of great high tech ingredients including several patented peptides such as Liquid Crystal which gives the product its name. . It has quite an interesting texture - like a thick viscous gel. You only use a pin head size ...
