A Yon-ka Favorite!

I immediately loved the feel of Yon-ka Hydrating Booster on my face. A couple drops added to my Optimizer Cream added the hydration I need during the cold, dry months. It is soothing with a gentle scent. I have used Yon-ka products for over 30 years. The results show.

Nutri plus is so nourishing and hydrating!

I love this serum!! I’ve been using it for a few years now, and my skin has changed for the better. It mixes so well with my moisturizer and isn’t heavy on the skin. I love that it prevents breakouts from occurring on my face as well. Top Notch Serum!

Yonka Serum

This is the best serum that I've ever used. I live in a very dry climate and my face always feels better after I apply it.

Yon ka hydration

Soon after the season changed, my skin became instantly dry. Thankfully so, Yon-Ka came to the rescue. It seems like the hydration slowly returned but returned none the less. I was using it every day, 2 pumps. Now, I believe I can decrease to 1 pump. My only complaint would be the delivery system. The product is not thick but more liquid and tends to run from my hand prior to being incorporated into the moisturizer.

Hydration booster

This can be added to boost the benefits of your moisturizer. I gave it 4 stars vs. 5 because the scent. I do not like strong scents on my face. Otherwise, it works its magic on your skin.

Serum Booster - excellent for mature skin or dry skin of any age

Adding a little booster with a day dream or a night cream helps your face glow and makes it look younger, softening wrinkle lines slightly. I've used it for several years and don't feel it needs to be used every day --just when your skin seems to need it.

This is a mood changer

I love love love this product! I can’t wait to use it every morning and evening! It’s calming. It smells like a high end spa. BUT the best thing is it makes my face so hydrated. I use it over my toner and serum. It’s a lightweight oil. I wish I could use it all over. Try it, I promise you will love it.

Yonka Always a Winner!

As a person with dry/aging skin I truly love this oil! This is a nice edition to their moisturizer as an added boost in hydration! My skin feels extra hydrated and dewey (which I love). I have yet to try a Yonka product that I did not love! Another winner from Yonka! Thank you!!

Yon-ka Booster Nutri

I love Yon-ka skin care and have used it for 20 years. I will say it seems that the booster Nutri formula has changed? It is heavier. I prefer the original.

One of my favorite products

I always put this defense booster on after cleansing my face. It restores my skin’s moisture balance. It’s not heavy at all... but a perfect lightweight blend of oils that is not greasy. It’s great alone or as a base for a day or night cream, and it’s very soothing for sensitive skin too (which I happen to have). I highly recommend it!

Great hydration boost

Great for additional hydration prior to applying a moisturizer. It really seems to absorb into the skin and boost hydration.

Great product!

I noticed some fine lines on my forehead earlier this year, and I decided to try the Defense + Antioxidant Booster, and I am impressed! I usually mix one pump of the serum with my nighttime moisturizer, and my fine lines have disappeared. I wear sunscreen every day but I was also concerned with UV exposure this summer, and I can honestly say my skin feels healthy and looks great since I started using this!

Defense + antioxidant booster necessity

I love this antioxidant booster! My aesthetician recommended it for my combination dehydrated skin. It's a very light nourishing oil that I add to my regular moisturizer (I alternate between Yon-ka Excellence for day and Environ at night), mixing it together in my palm and apply together. Defense + is particularly nice for travel, combating the dryness that occurs from air travel and change in environment. I like how it leaves my skin looking dewy and glowy, not overt shiny. My makeup goes over it easily or for those natural no make-up like days my tinted sunscreen also works well with it.
