Experience the power of scientific innovation with our cutting-edge KHUS+KHUS C DROPS, a breakthrough vitamin C serum formulated with 10% Tetrahexyldecyl ascorbate. Backed by extensive research, Tetrahexyldecyl ascorbate has proven to be a superior alternative to traditional L-ascorbic acid in skincare. Here’s why you should choose C DROPS with Tetrahexyldecyl ascorbate over L-ascorbic acid, and the remarkable benefits each ingredient brings to improve your skin health.




Tetrahexyldecyl ascorbate, a lipid-soluble form of vitamin C, represents the latest breakthrough in skincare. Its unique molecular structure allows for deeper penetration into the skin, resulting in enhanced effectiveness and superior results. Here’s why it outshines L-ascorbic acid:

  • ENHANCED STABILITY: Tetrahexyldecyl ascorbate remains stable even in the presence of air and light, ensuring the potency of vitamin C remains intact for longer periods. This means that every drop delivers the maximum benefits of vitamin C to your skin.
  • INCREASED BIOAVAILABILITY: Unlike L-ascorbic acid, Tetrahexyldecyl ascorbate readily penetrates the skin’s lipid barrier, allowing it to be absorbed more efficiently. This enhanced bioavailability ensures that the active form of vitamin C is delivered precisely where it is needed, promoting optimal skin health.
  • POWERFUL ANTIOXIDANT PROPERTIES: Tetrahexyldecyl ascorbate exhibits exceptional antioxidant activity, effectively neutralizing harmful free radicals. By reducing oxidative stress, it helps to prevent premature aging, brightens the complexion, and improves overall skin tone and texture.


SIBERIAN SEA BUCKTHORN | NATURE’S SKIN SAVIOR   Rich in Vitamins and Nutrients: Siberian sea buckthorn is packed with vitamins A, C, and E, as well as essential fatty acids and antioxidants. These nourishing components work synergistically to promote collagen production, boost skin elasticity, and repair damaged skin cells, resulting in a youthful and radiant complexion.


OLIVE-DERIVED SQUALANE | THE ULTIMATE SKIN MOISTURIZER   Harnessing the power of olive-derived squalane, a natural emollient known for its outstanding moisturizing properties. A game-changer for your skin:

  • DEEP HYDRATION Olive-derived squalane mimics the skin’s natural lipid barrier, effectively locking in moisture and preventing water loss. It hydrates your skin from within, leaving it plump, supple, and nourished. 
  • SKIN BARRIER RESTORATION Helps restore the skin’s protective barrier, strengthening its resilience and defending against environmental aggressors. By fortifying the skin’s natural defense mechanisms, it helps maintain optimal moisture levels and promotes a healthy, glowing complexion.

    Another fantastic product from Khus-Khus! Absorbs quickly, moisture without nasty chemicals or sides affects. Highly recommend the entire line.

    Bought the C Drops along with the Kama balm and they are a formidable pair. The drops have a soft floral scent that sink into the skin and a thin layer of Kama balm on top with gentle Jasmine tones make my skin feel exquisite. Two new products, two new favourites

    I love this C Drop Serum! It is the perfect dose of highly effective, absorbing vit c. I use it twice daily morning and night after toning mist, then C drops and followed by the SEN face serum oil. Love all khus-khus products!!

    Love this product. Not only does it leave my skin silky smooth but it also has helped in fading a few post acne scars I had!

    Holy Grail. I’m on my 2nd bottle and I use it during the week in the morning to pair it with RESQ or KAMA after Special K toner. Winning combo for winter blues. I’ve consistently used C drops for over 30 days and can tell it’s been contributing to keeping my skin moisturized n better application IF I decide to wear makeup.

    I first was introduced to Khus khus from a good friend of mine who was an ecstation at my salon. I love her and I love her recommendations. Khus khus is wonderful. These vitamin c drops are the best. Really not greasy and they feel wonderful on my face. I really feel it getting into my skin. The scent of these products are amazing.
    I love the fact that everyone works with you on these wonderful products. Thank you.

    My take on the C drop serum has been excellent and my face didn’t have any irritations first time using the serum. I’m been using it 3x a week and applying it at night and love how my skin is smooth and with brighter and clearer complexión. Highly recommend this product that contains the purest ingredients.

    I love this serum. I’m nearing 70 years old and my skin feels so soft after applying this. It soaks into my skin beautifully.

    Another beautiful product from Khus Khus. I use the C Drop alone and sometimes before Sens serum. Moisturizs and balances the skin. All of the products (I have tried it all) are amazing and holistic in healing me inside and outside. What a nice way to nurture one’s day in beautiful grounding scents, and go to bed feeling a state of harmony. Khus Khus is skin yoga!
