THE COSMEDIX DIFFERENCE
Powerful Results, Visible Transformation.
NEW ARRIVAL
Liquid Glow Eye + Lip Duo
Our bestselling Opti Crystal eye serum paired with Lumi Crystal lip treatment in one limited-edition holiday duo designed to visibly hydrate, smooth, and refresh the delicate eye and lip areas.
Liquid Glow is COSMEDIX's limited-edition holiday eye and lip duo featuring Opti Crystal, our #1 bestselling eye serum, paired with Lumi Crystal lip treatment. Both powered by Liquid Crystal Technology, this professionally curated duo delivers intense hydration to help visibly reduce the appearance of fine lines, dark circles, and dryness in the delicate eye and lip areas.
Opti Crystal has earned its place as the most beloved product in the COSMEDIX collection for good reason. Its unique Liquid Crystal Technology mimics the skin's own lipid structure, creating a seamless delivery system that helps replenish essential moisture where delicate skin needs it most. The result is an eye area that looks brighter, smoother, and more refreshed.
Lumi Crystal extends that same professional-grade hydration technology to the lips. Formulated with Palmitoyl Tripeptide-38 and Ceramide NP alongside Liquid Crystals, it helps support the look of fuller, smoother, more hydrated lips while helping to diminish the appearance of fine lip lines.
Together, these two formulas create a complete eye and lip ritual that addresses the areas where skin is thinnest and most prone to visible signs of dehydration and aging. Unlike single-product approaches, Liquid Glow pairs targeted eye care with dedicated lip care for a more comprehensive result.
Both formulas are enriched with Spin Trap, a potent antioxidant that helps defend against the visible effects of environmental stressors. Copper Gluconate in Opti Crystal further supports the look of firmer, healthier-looking skin around the eyes.
Inspired by the treatment room and trusted by aestheticians worldwide, this duo reflects COSMEDIX's 25-year commitment to professional skincare that delivers visible results through clinically advanced, botanically rich formulations. Liquid Glow returns this holiday by customer demand, making it easy to gift professional-grade eye and lip care or elevate your own daily ritual.
Back by customer demand. $140 value. Yours for $105. Available for a limited time.
What is the Liquid Glow duo?
Liquid Glow is a limited-edition holiday pairing of our #1 bestselling Opti Crystal eye serum and Lumi Crystal lip treatment. Together, they create a complete hydration ritual for the delicate eye and lip areas, powered by Liquid Crystal Technology.
Who is this duo best for?
Anyone looking to address dryness, fine lines, or dark circles around the eyes, plus lip dryness or visible lip lines. It's ideal for all skin types and works beautifully for both skincare enthusiasts and anyone new to professional eye and lip care.
What is Liquid Crystal Technology?
Liquid Crystal Technology uses a cholesteryl complex that mimics the skin's own lipid structure, allowing the formula to deliver deep, lasting hydration exactly where delicate skin needs it most. It's the foundation of both Opti Crystal and Lumi Crystal.
How do I use Opti Crystal and Lumi Crystal together?
Apply Opti Crystal first: use a tiny amount (just a dot) around the orbital bone with your ring finger, AM and PM. Then apply Lumi Crystal directly to clean lips. Both can be used morning and evening as part of your daily routine.
Can I use this duo with my retinol or other serums?
Yes. Apply your treatment serums first, then layer Opti Crystal over the eye area. Opti Crystal pairs well with retinol products, vitamin A serums, and growth factor treatments. Apply Lumi Crystal to lips as the final step.
How long does one tube of Opti Crystal last?
Opti Crystal delivers over 147 uses per tube when applied correctly (just a dot per application). At twice-daily use, one tube lasts approximately 10 weeks.
When will I see results?
Many customers notice improved hydration and a brighter, more refreshed appearance around the eyes within the first week of consistent use. Visible improvement in the look of fine lines and dark circles typically becomes more noticeable with continued daily use over 4 to 6 weeks.
Why do aestheticians recommend Opti Crystal?
Aestheticians trust Opti Crystal because its Liquid Crystal Technology delivers hydration in a way that closely mimics how skin naturally retains moisture. It's been the #1 bestselling product in the COSMEDIX professional line for years and is a staple in treatment room protocols.
Is this available year-round?
No. Liquid Glow is a limited-edition holiday exclusive available only while supplies last. Opti Crystal and Lumi Crystal are available individually year-round, but the holiday duo pricing ($140 value for $105) is only available this season.

I have been using this for the past five years, and a tiny drop goes a very long way and does miracles for around your eye. I’m 65 years old and don’t have a crease or just coloration under and around my eyes.

I've been using this eye serum for 15+ years, and I believe it's made a difference in the aging of the skin around my eyes. At 50, I don't have static wrinkles. I haven't found anything else to be as hydrating.

I’ve used many under eye serums before; however, nothing beats the results I have received from using Opti Crystal. I’m extremely pleased with the results. In addition, the price point is reasonable for the results achieved.

I really like this product. It immediately pumps up and moisturize the lips when you put it on. And I love the little sparkle effect it has.

Found this product quite by accident! Decided to try something new as my usual under eye moisturizer was not working well for me anymore. My salon carried the Cosmedix line and my stylist recommended Opti Crystal, her favorite! Was more pricey than what I usually pay, but gave it a try anyway. Glad I did! I have been using this product FOR YEARS!

Love this! I used Eye doctor years ago and enjoyed it but then recently my esthetician suggested Opti Crystal and it works wonders! I will say I don’t see much difference not wearing it but it corrects and it great when I apply!

This little tube packs a punch- I noticed a difference to tone and fine lines within the first week. A bit "sticky" to apply, but absorbs well and leaves a nice glow.
