Frequently Asked Questions
Which skin type is Biopelle KNR Serum suitable for?
Biopelle KNR Serum is formulated for use in all skin types, including normal, combination, oily, and dry. Biopelle KNR Serum does contain retinol which may cause some irritation in sensitive skin, therefore, it is a good idea to reduce initial application to every other night for the first two weeks.Â
What does niacinamide do for skin?
Niacinamide, also known as Vitamin B3, has many skin benefits including reducing hyperpigmentation and brightening skin tone, improving fine lines and wrinkles, and helping smooth and moisturize skin.
When will I start seeing results?
Results will vary depending on severity of pigmentation and skin aging . In a clinical trial, sensitive skin patients with melasma, a very resistant form of pigmentation, saw significant improvement in pigmentation at three months. It is important to note that pigmentation in sensitive skin is a delicate balancing act because irritation can lead further pigmentation. For this reason, initial application was limited to every other night for the first two weeks during this clinical trial. (Source: Evaluation of Efficacy & Tolerability of a Pigment Correction Serum in Asian Women with Melasma, IMCAS poster 2022) If you do not have sensitive skin and/or have mild uneven pigmentation, you can expect to see results sooner.
How long does one container of Biopelle KNR Serum last
One container of Biopelle KNR Serum should last approximately 3 months when applied once nightly to the face. If you are applying to the face and neck, your container may not last as long.
Which products should I use with Biopelle KNR Serum to enhance my skincare routine?
For enhanced brightening results, we recommend partnering Biopelle KNR Serum with one of our daytime serums, either Biopelle Antioxidant CE Plus Serum or Biopelle C+AHA Renewal Serum. And to enhance the eye area, Biopelle Triple Action Eye Serum is a multi-tasking eye serum with Vitamin C.

I have been shocked by how much of an impact the KNR Serum has had on my face and complexion! I started seeing a difference right away. My skin is tighter, smoother, more even in skin tone and feels extra youthful. Until now, I had only experienced these kinds of results after certain intense facials in the past, but never with a serum that immediately impacts my skin in the best way. My favorite part is how glowy my skin is feeling now that I’ve been using this. I have more glow and smoothness than I’ve had in a very very long time. I LOVE THIS PRODUCT!

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.

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.
