Black Pearl Resurfacing Serum



1OML SERUM: $65 (Trial & Travel size; 10 – 14 day supply)

30ML SERUM: $175 (Full Size)


Scientifically formulated with Black Pearl and ingredients in the complexion-reviving Advanced Resurfacing Complex, the Black Pearl Resurfacing Serum is well-equipped to resurface, renew, and retexturize skin of any age. Just a few drops and you’ll slough off dead skin cells to reveal smoother, fresher skin. 


Resurfacing | Renewing | Retexturizing | Pore-Refining | Exfoliating | Revitalizing | Blemish-Minimizing |Wrinkle Smoothing | Increases Cell Turnover


Power-packed with a total of 8 AHAs and 2 PHAs, this serum is ready to transform dull to dazzle. Working together, the gentle exfoliation, pore-minimizing, and hyperpigmentation-reducing benefits of Lactic Acid are supported by the small molecular size of Glycolic Acid, which penetrates skin to trigger collagen production and contribute to a 59% increase in skin smoothness (over 2 weeks). Low-irritating, high-exfoliating Mandelic Acid sloughs away dead skin cells, while also promoting cell turnover to support brighter skin and restore its natural glow.

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.

My favorite

This is my favorite treatment serum. I compare it to U Beauty where it's one serum that does a lot of different things. I love the daily, gentle exfoliation that makes my skin smooth and I feel like it's keeping it clear of breakouts/clogged pores too.


  • Black Pearl: A “Queen of the Sea” ingredient sourced from the deep, turquoise waters of Tahitian lagoons that has been used for thousands of years in traditional Chinese medicine for its contribution to nourished, moisturized, and protected skin.
  • Lactic Acid: A gentle AHA that is clinically proven to exfoliate, reduce hyperpigmentation, minimize pore size, and promote smoother, brighter, and more uniform skin.
  • Glycolic Acid: An exfoliating AHA that reduces the appearance of fine lines, wrinkles, and blemishes and works with Lactic Acid to contribute to a 59% increase in skin smoothness and 88% improvement in skin brightness in just 2 weeks.
  • Mandelic Acid: A low-irritating, high-exfoliating AHA that promotes cell turnover, an even skin tone, and a reduction in hyperpigmentation—resulting in brighter, healthier skin.
  • Gluconolactone: A moisture-attracting PHA that hydrates, gently exfoliates, dissolves dead skin cells, and imparts anti-aging effects. 
  • Lactobionic Acid: A highly skin-compatible PHA and humectant that moisturizes and restores skin’s barrier, while joining Mandelic Acid and Gluconolactone in producing a 16% reduction in dark spot appearance (over 56 days).
  • AHA Fruit Acid Blend: A combination of 5 AHAs—from Bilberry, Sugar Cane, Orange, Lemon, and Sugar Maple extracts—that immediately contributes to rejuvenated, moisturized, and wrinkle-free skin, all while sloughing off dead skin cells and increasing rates of cellular renewal.

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.


Black Pearls are aligned with the Root Chakra or First Chakra, located at the base of your spine. Balancing your Root Chakra allows you to feel grounded and secure as you move forward on life’s journey.  As you relax and apply the serum, take deep cleansing breaths and repeat the mantra, “I am Grounded” three times. Set the intention for yourself to feel grounded, secure, and safe in the here and now.


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 Black Pearl Resurfacing Serum with our Obsidian Gemstone Roller to facilitate serum absorption and balance your Root Chakra to feel more grounded. 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.
