Cellular Code Serum | Anti-Aging Face Serum | Firm Skin and Soften Appearance of Wrinkles with Cell-Energy Natural Youth Complex | Paraben-Free | 1.01 fl oz

This is a great lightweight serum. I love that this product feels both light on the skin yet high in moisture. It absorbs quickly and does not leave your skin oily at all. It has a very fresh leafy scent. I use cellular code before my sunscreen as one of my final steps in my morning skincare routine. Great product!

This is one of the best serums I've used - it's lightweight, moisturizing, smells incredible and feels very high quality. It almost feels like a lotion and is not oily. I will continue to buy - it feels like I've just come back from the spa because the scent is so soothing and calming for skin and mood.

I have used Yon-Ka's Cellular Code Serum for a couple years and love it. I use Yon-Ka products and have for over 20 years.

I've been using this product for at least 2 years (started when I was 50). Last year I tried something else hoping I could save some money, but after only a month I could see a difference. Fine lines started to appear and my skin lost its glow. I won't use anything else but Yon-ka Age Exception products!

This Yon-Ka Cellular Code serum is lightweight has a milky or cloudy white color. The texture is a lightweight, slippery gel that absorbs quickly. The pump dispenser works well. The ingredients also contain jojoba oil esters as an emollient, but are otherwise rather unimpressive, especially at this price point. Maybe I'm wrong, but I don't think the claims of the ingredients in the "Cell Energy Complex" that they list are backed up by science. Also, the serum has a floral scent from both fragrance and a mix of essential oils, including lavender, bergamot, lemon, orange and geranium. Both fragrance and essential oils can cause irritation for sensitive skin. It's made in France.

Love this product and love the savings on Amazon vs the salon!

This serum feels incredibly elegant on my dry, sensitive skin — lightweight but deeply hydrating. It absorbs fast and leaves my skin soft and smoother without any irritation. After a couple of weeks, I noticed a more even texture and a subtle firmness around my cheeks. The aloe-based scent is gentle and didn’t bother my skin at all. It’s definitely pricey, but it feels luxurious and performs like a true treatment.

I got a facial and the esthetician sold this product to me with another Yonka cream as a set to use for my face. I'm so disappointed that I felt the need to write the review because the combo for the 2 Yonka products she sold to me was $344.00 and did absolutely, positively, nothing for me. I saw no difference, at all, whatsoever, and $344.00 is not chump change to be spending on products that do not work. I was also told that this product would last a number of months, but it maybe lasted me 5-6 weeks. I specifically said that I did NOT want to purchase this product if it would only last a month for that kind of money, unless it was some kind of miracle cream. I was assured it would last longer AND that I would see results. I used it exactly as told and also read in the pamphlet, and it surely would never last as long as I was told by the esthetician, and no way would it last for months! I write this review ONLY to let others know my experience with this product (Yonka). Maybe just take caution in purchasing this product since it is expensive and also since I personally saw no results at all. And, I am not happy about it.
