      • Smells sooooo good
        I had to wait for this as it was out of stock for the longest time! So worth it. The smell alone is the most relaxing part of this luscious, silky smooth serum and the results in just 3 weeks prove to me that the skin advisor camera app really works!

        The smell of this serum is enough to make me fall in love, but it feels great going on and has changed my skin since I started using it. A little goes a long way, so it's a good investment too!

    Optimizer Serum is one of my favorite Yonka products and have used for a number of years. Love the firming quality in combination with Optimizer Creme!

    Bye bye to wrinkles
    Using this around my eyes and forehead takes the deep lines away. Notice a difference in a week.

    Effective serum
    I’ve been using this in conjunction with the Optimizer moisturizer for about 3 weeks and my skin does appear a little smoother and firmer. I like the light texture of this serum which I apply after the mist. Looking forward to seeing how this continues to perform over time

    Can't live without it
    While vacationing in Ireland, I was introduced to Yon-Ka serum during a facial at a local spa. I loved the feel as soon as it contacted my face. I purchased a bottle 3 years ago and have never gone without it since. Not only did it sooth upon contact, I noticed a softer and smoother "glow" to my skin. After I cleanse and tone, I apply the serum and then my daily moisturizer. Although it is expensive, it is my must have product. I've tried other serums but nothing compares to Yon-Ka.
