How to Use

After cleansing and applying any other Brightening products, apply KNR Serum to entire face once or twice daily or as directed by your skin care provider. If applying in the AM, use of SPF 30 or higher is recommended.

Utilize XCP in the morning and KNR at night to coincide with the skin’s circadian rhythm and skin’s natural defense/repair process.

    My skin is glowing after each time I’m using it. Also after using it for 3 weeks I really see the difference. My skin got brighter.

    I feel like this serum significantly reduces the amount of time I spend on skincare because it’s like multiple products in one, which is perfect for my busy lifestyle. After years of neglecting my skin during the pandemic, this serum has started to transform my skin. My skin is looking brighter and the hyperpigmentation is fading, which has been so hard for me to achieve. Highly recommend.

  3. Angela Rhen

    I absolutely love this product. My skin looked dry, and cracked. I hated putting makeup on. Since I’ve been using this serum my makeup looks so good. I’ve noticed a huge difference in the texture, and complexion of my skin. I highly recommend this product to anyone with aged skin.
