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 really like this product and noticed a significant difference in the tone of my skin after just 2 months. My skin is more even and freckles lessened. I use morning and evening, and put on 3 pea sized amounts each time followed by sunscreen, at least in the am. Highly recommend!

I have been using this serum at night and noticed that my skin is clearer. I suffer from redness, and I can already notice my redness decreasing. This serum was safe and gentle for my sensitive skin. I am excited to continue using this serum to see more benefits.

I’ve been using this serum both AM & PM and I’m really happy with it so far! My skin feels more rejuvenated and nourished. I recently had a chemical peel & needed to find quality products to help maintain that glow, and this serum was the one. The serum glides on really well on my skin too!
