Diamond Radiance Serum



1OML SERUM: $80 (Trial & Travel size; 10 – 14 day supply)

30ML SERUM: $225 (Full Size)


Scientifically formulated with luxurious Diamond, the Diamond Radiance Serum features an Advanced Brightening Complex, which harnesses a range of clinically tested ingredients proven to even tone and contribute to brighter, more illuminated skin—leaving you glowing, both inside and out.


Brightening | Radiance-Boosting | Renewing | Tone-Evening | Glow-Restoring | Imperfection-Blurring | Age-Defying | Minimizes the Appearance of Dullness, Discoloration, and Dark Circles 


Just as multifaceted as Diamond Powder itself, brightening powerhouse Tranexamic Acid works as a heaven-sent to reduce age spots, even skin tone, and restore skin’s radiance—especially when paired with Ascorbyl Glucoside, a gentle form of Vitamin C that ensures long-lasting radiance and a more even skin tone. Working to degrade dark spots instantly and gradually, gentle Arbutin is joined by other best-in-class brightening ingredients to turn lackluster to luminous. 

All serums are crafted using Advanced Complexes, which are a more potent, powerful take on the serums found in our masks. Still, they feature our proprietary GEMCLINICAL® Technology, which acts as a one-way delivery system to maximize infusion of the doctor-formulated ingredients and enhance the treatment results.

I recommend this product

Love love love

I’ve purchased this serum two weeks ago for my vacation. It feels great on my skin. It leaves my skin hydrated, bright and glowing. Despite long hours on the beach, dry climate my skin feels and looks bright and energized. I’m definitely buying a full size. Highly recommended

Loved it, but agree it ran out fast

I have loved the masks and eye masks for years and bought the smaller size serum. It was great, but I agree with the other reviewer in that it ran out quickly. $80 for that bottle size compared to skinceuticals and other products that last months and months with the same use, is just a bit unrealistic. I’m debating whether to buy it again because I did love the product.

Hi We are so happy you love our serum as much as we do! We put so much love and highly effective ingredients into these formulas. Please note that this "trial and travel" mini size is about 1/3 of the retail size. We wanted to offer customers a way to try out the formulas with this size that should last 1-2 weeks (1-2 drops per day). This size is also ideal for many of our customers who also cocktail with other serums, spot treat, or rotate their skincare products. - The Knesko Team


Works well, ran out fast

I purchased the product to try and it felt great on my skin! Unfortunately, I ran out very quickly using it at the recommended twice daily. I don't feel like I used it long enough to notice a huge difference in my skin in just over a couple weeks. I wish there was more product to last longer!

Hi! We're so happy to hear that our serum felt great on your skin. The 10ml serum is 1/3 the size of the 30 ml serum which is the traditional size that's most commonly available in stores. However, we wanted to create an introductory size that is intended to be used as a trial usually lasting 10-20 days (depending on whether it is the only serum that's being used and the amount of serum that is applied per use). In your experience, it seems that it did last you a couple of weeks which is the correct timeframe for any 10ml. If you really did love it our recommendation is to upgrade to the traditional 30 ml size which also does come at saving for the larger size. These are clinical serums with cumulative effects. We are thankful for your feedback and hope you will give it another chance. - The Knesko Team

As a core of KNESKO’s philosophy, we take a holistic approach to beauty. Our products are infused with gemstones and minerals and charged with Reiki Energy by our founder and Reiki Master, Lejla Cas. The gemstones have been consciously selected to help balance a different chakra, or energy center, and each chakra is associated with a different mantra, or positive intention. 


Improved wellness is not just for your skin—but also for your soul! Our chakras become blocked when negative thoughts or stress invade our lives. This has a detrimental effect on our spirit, and also accelerates signs of aging on our skin. By rebalancing your chakras, you eliminate stress and open yourself to self-love, gratitude, and healing. 

As a practice anyone and everyone can do, repeating a mantra centers your mind on optimistic thoughts and draws your focus to positive intentions, bringing only good energy into your life.


The queen of gemstones, Diamond is aligned with your Crown Chakra or Seventh Chakra, located at the top of your head. Balancing your Crown Chakra allows you to access enlightened wisdom and utmost clarity. As you apply the serum, take deep, cleansing breaths, and repeat the mantra, “I am Connected” three times. Set the intention for yourself to restore feelings of oneness with the universe.


Every luxurious bottle of serum is infused with our proprietary GEMCLINICAL® Technology which enables the infusion of effective minerals and gemstones into the serum and maximizes the delivery of all active ingredients into your skin.  

The glass bottles themselves have been carefully crafted to mimic each beautiful gemstone featured in the collection. They’re also manufactured with recycled materials and designed to be upcycled and/or recycled after use. 

  • Give yourself permission to take the time for self-care, and open your mind to a transformative experience.
  • Cleanse your skin to remove any traces of dirt, make-up, or lotion.
  • Add 2 to 3 drops of serum to clean skin and gently pat in, in an upwards and outwards motion.
  • Follow up with your skincare regimen.
  • We recommend pairing our Diamond Radiance Serum with our White Jade Gemstone Roller to facilitate serum absorption and unlock your Crown Chakra to feel more centered. Sweep the larger roller from the hairline towards the ear, down to the temple. Use the small roller to sweep from the inner corner of the eye to the ear. The larger roller can sweep from the nose out to the ear, then across the upper lip, lower lip, and chin.
  • For best results, use the serum daily, in the morning and/or night.
