    Best of all the rest
    I have used YonKa products since I discovered them on a trip to Paris in 1998. What I love most is they can be trusted. The ingredients meet all EC requirements (US manufactured products don't have these protections) and are natural and non-reactive. All that said, I live in dry air above 5,000. Hydra No. 1 is my year-round go-to moisturizing base to keep my face and neck supple and hydrated. I love the way it feels, how it goes onto my skin and doesn't disappear, yet is light as air. Perfect base for Elastine Jour or any other moisturizer. I'm 62 but many tell me I look over 10 years younger. It's not me, it's my skincare products. Thank you YonKa!

    my favorite hydration serum
    I love the way it makes my face feel so smooth and totally minimizes the small lines on my upper lip. I also use it to help the tiny wrinkles near my eyes when I smile. I love the way it goes on and it has made me feel good about how I look.
