It's a formula unlike any other, boasting a uniquely crystalline appearance that dazzles at first sight (and that lends it that fitting 'unicorn' moniker).
The opalescent effect is super pretty, with a mesmerizing swirl of purples, greens, and blues that lends it a look of resin art. If you buy it just for the good looks, well, this is one time it's totally fine to judge a book by its cover.
We would not recommend that if the product weren't amazing, but COSMEDIX has a sheer winner on its hands with this gorgeous serum. It starts out as a velvety balm, melting down into a super smooth consistency as you pat it around your eyes.
That lends the entire application experience a spa-like vibe, which alone is a huge plus point. It's impossible not to feel like you're doing something really nourishing and healing for your skin.
At the heart of the formula is eucalyptus, known for its soothing and revitalizing properties. It also contains spin trap, a potent antioxidant known for guarding the skin from environmental distress (aka the free radicals that lead to early signs of aging).
With copper complex added to firm up the delicate undereye area and liquid crystal technology playing the superhero by basically replicating your skin's natural barrier to leave the area softer and plumper, the treatment delivers stunning, noticeable results.
In fact, the serum is specifically formulated to reduce all of those concerns that affect the eye area: fine lines, wrinkles, dark circles, and dryness are all no match for this product.
Shoppers genuinely love it, sharing that it's made all the difference to their overall appearance. 'A must-have,' said one pleased reviewer. 'This product works hard to stop further damage and show signs of reversing the existing damage.'
' Opti Crystal will forever be my holy grail eye serum. Nothing gives me results like this. I've definitely noticed a reduction in the fine lines around my eyes since using this as well,' raved another.
A third had high praise, writing, 'Miracle for my eyes! It's brightened up my dark circles and reduced puffiness, leaving my eyes looking more awake and refreshed. I also love how it has a slight luminous finish—perfect for days when I don't want to wear makeup but still want my eyes to look bright and revitalized.'
What more could you ask for in an undereye treatment? Grab the COSMEDIX Opti Crystal Liquid Crystal Eye Serum for a rare 25 percent discount (and don't miss the brand's other highlights while you're there). It doesn't go on sale often!
