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.

This is a solid serum. It lightened some hyperpigmented areas on my face, which is a big plus. This product took a little bit longer to absorb into my skin, but overall, I am happy with the outcomes. I received this product in exchange for an honest review.

I apply this serum at night so that it can do the work while I sleep! It has a power-trio with kojic acid, niacinamide and retinol.  My sensitive skin does not react poorly to this serum. It also absorbs nicely into my skin and isn’t sticky. I’m really enjoying the light fragrance, too!  I’m hoping to see less hyperpigmentation and wrinkles with continued use. I received this product in exchange for my honest opinion.

As someone who loves taking care of my skin, I was thrilled to try out Biopelle KNR Serum. Full disclosure, I received this product in exchange for my honest review. After using it consistently for four weeks, I can confidently say that it lives up to its promises.
The first thing that I noticed about this serum is its lightweight texture. It absorbs quickly into the skin without leaving any greasy or sticky residue, which is a huge plus for me. I also appreciate that it has a subtle fragrance that is not overpowering or too strong.
What I love most about this serum is the visible improvement in my skin’s texture and tone. After the first use, I noticed that my skin felt smoother and more refined. Over time, my skin looked more even-toned and brighter. I also noticed a reduction in the appearance of fine lines and wrinkles, which was a pleasant surprise.
In addition to the cosmetic benefits, I appreciate that the serum contains powerful antioxidants and growth factors that help to nourish and protect the skin. My skin feels firmer and more hydrated, which is always a good thing.
Overall, I highly recommend Biopelle KNR Serum to anyone looking for a high-performance serum that delivers visible results. It’s definitely a product that I will continue to use in my daily skincare routine.

At first my skin had a reaction to this serum. This is the first time I have used anything with retinol and my skin turned red the first couple times I used it. I continued to use it and the redness went away. I definitely see some improvements in my skin with using this. My skin is brighter. My skin is smooth and is clearing up. I can’t wait to see what my skin looks like with continued use. I received this serum free for my honest review.

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.
