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’ve tried so many retinol products and many irritated my super sensitive skin. This seems to have a gentle formula that does not irritate my skin at all, but still delivers great results. I absolutely love that it comes in a pump bottle versus a pipette bottle. So much easier to work with and always ensures to apply the right amount.

The KNR Serum is my nighttime favorite. I love how luxurious this serum feels as it truly glides on and instantly feels like it is loving on my skin. My skin is clearer and brighter since using this serum. No strong smells – light and just right. I am grateful for the opportunity to try this product and offer my honest review. It is a win for me!

Just look at the skin pampering ingredients: kojic acid, niacinamide and retinol plus vitamin C and peptides. This serum helps to brighten skin, improve texture and tone, reduces appearance of dark spots and support cellular turnover and regeneration. Wow those are amazing benefits. I love how well this serum has fit into my routine and enhanced the overall look of my skin. Received in exchange for my honest review.

As I enter my 40s, I have noticed a few skin concerns dullness, uneven skin tone, and pigmentation. I started using KNR serum at night about a week and a half ago, and I have been amazed by the improvement I have been seeing. My pigment spots are slightly lighter and there is a small improvement in my overall skin tone as well. I am absolutely in love with the Serum. Here are the key ingredients of this serum: kojic acid, niacinamide, and retinol.

I’ve been using this serum at night for a few weeks now and I’ve seen such an improvement in my skin. It’s clearer, brighter and my skin tone is more even. I was sent this serum in exchange for an honest review and I’ve been so happy with the results.

I was a tad worried the niacin in this would increase my highly natural flush that already exists, but nope! No increased flush, no undesirable tingle or sting upon application, and the retinol has does wonders for firming my skin in just a month of use! I feel more bright and youthful. The serum is not at all sticky or tacky.

I received the Biopelle KNR Serum in exchange for an honest review and I was happy to use this product in my daily routine. Hyperpigmentation has always been my problem so I was excited to see how my skin improved over a few weeks. Added to my nighttime routine I would wake up with brighter skin and a feeling that my skin was repaired overnight. Definitely, a must-have to maintain bright, healthy skin!
