    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.
