• Exceptional product 5

  Posted by Olga Hehl via YonKa.com on Dec 12th 2020

  My only regret is not having used this product sooner. It is easy to apply, quickly absorbed and the results are noticeable almost immediately. Ever since I purchased it, I've been using it every morning and almost every evening - after washing my face and using the Lotion Yonka PS. Sometimes, in the evening, I use Elixir Vital as a serum, instead. This routine is working well for me. I plan to purchase this product again and to continue to make it a part of my daily, skin care routine.

• Excellent product, could really tell a difference using it 5

  As a 68 year old woman I have tried many serums and moisturizers over the years. Yon-Ka products and the Cellular code serum specifically are the best I have found for helping older skin stay supple and lifted with fewer wrinkles. Highly recommend this product.

  This was a Christmas present to myself because I wanted to try this. I have been using this for over a week and have already noticed a difference. Well worth the price

  This is the best serum, you will ever use. I use it with all the other products in this line. Love Yonka.

• The Best AntiAging Serum EVER 5

  This serum is hands down my fave serum of all time! I have a really good skin care routine and genetically blessed skin but as soon as I started using this I could not believe the results! My skin looked even younger and within 2 weeks I was receiving compliments left and right! I try and use one bottle at least once a year to keep my cells active. It's totally worth it!!

  Simply the most wonderful products. Started using the Yonka line I will not turn back. I'm not young anymore, but these products have made me feel like I am. Try these Yonka products you will get best results ever.

  I am 72 years old and people cannot believe my skin. I have used Yonka for about 6 years and have almost no wrinkle. This product makes my skin look very youthful. Love it.

• A reformed skeptic. 5

  I have purchased countless skin care products over the course of my 60 years on this planet and honestly I never saw a difference in my skin until I had a facial with Yon-Ka products. I was sent home with several samples of the Excellence and Cellular Code line. I'm shocked, truly. Wrinkles were greatly reduced immediately and my skin is hydrated and dewy. I've kicked myself over and over in the past for spending money on skin care products that were a waste of money. This is the FIRST product that provides convincing results not only from my perspective, but close friends and coworkers also remark at my improved complexion. It's truly transformational. I wish I had taken before and after photos.
