WOW!

I’ve always stayed away from serums due to the thick, sticky feel of them and never over emphasize the value of any product. That being said, I cannot believe the difference this product has made in the feel and appearance of my skin. I am 72 years old and my skin has never looked this good! It is brighter and smoother due to the Vitamin C. The drawback, of course, is the price. Very expensive. If I wish to continue using this, I will need to switch to a lower priced moisturizer. But this product has improved my complexion so much, the tradeoff will hopefully be worth it.

Nice oil but too small a bottle for the price

It didn't last me long enough. Putting the oil first in my hand uses up some of the precious oil.

Effective

This Vitamin C is great! I have been wanting to try it, but the price point was a bit high. LovelySkin had a great sale, so I decided to try it and I am glad I did. My skin looks brighter and helps with my pigmentation too! 4 stars because of the price!

Amazing Vitamin C Serum

A new favorite! From the scent, to the texture, to the feel, this serum is one that I will continue to purchase. A little goes a long way. A must try!

High vitamin c content

Referred by my esthetician, this serum is a favorite. It smells great, brightens, and feels good. Love it on my mature skin.

Yonka serum C-20

I have been using this serum every morning for many years. It’s kind to my matured skin and by using a toner prior it goes a long way.

Provides Excellent Hydration

The Yon-Ka brand is new for me. I purchased this serum to use with my evening routine, as I already use a different brand of Vitamin C serum in the morning. This serum goes on smoothly and smells wonderful. I use it under a rich moisturizer and the combination is perfect for my skin. I'm active outdoors during the winter and so far my skin feels/looks hydrated and there's not a dry patch in sight.

Love, but too expensive for me!

I was introduced to Yon-Ka products about 2 years ago and now I am obsessed. I have even converted a few friends after letting them try my products. The smell and feel of this product is heavenly and I definitely notice a difference in regards to brightness when I use it. I just use so many Yon-Ka products that I felt like I was adding too much and, for the price, I just couldn't justify reordering it. I have rosacea and sensitive skin and this did not irritate it at all.

Great Vitamin C

I’ve been in the skincare industry for several years and I’ve tried countless vitamin C serums. I like all natural skin care and items that pack a punch. This is one of the best vitamin C serums I’ve used and you can see a noticeable difference in 48 to 72 hours. It’s a bit expensive but you really only need 7 to 8 drops to cover your entire face so it should last a good while. It’s only necessary to use it in the daytime.

This Yon-ja serum is amazing! It makes my skin feel so nice and smooth. I noticed my sun spots have lightened up.

Strong fragrance

The texture is pleasingly light weight and smooth. It absorbs easily. But the bubblegum scent is very artificial. I expected a vitamin C serum to be all natural.

Great Product!

After receiving a free sample, I ordered this product and love it! I believe it’s making a difference in my skin. I just turned 60, and am often told I look much younger than my age. I attribute this to using great skin care products, including this Vitamin C product.

Lightweight and works well!

I received a sample from Lovely Skin and when I was done immediately ordered a full size bottle! This vitamin c serum is much lighter than Skinceuticals and works well paired under my hyaluronic acid serum. I use a lot of Yonka products and really recommend this one!

New Vitamin C Favorite!

My esthetician introduced me to this product line and then I tried the Vitamin C Serum C20 and was hooked immediately. I've been using other Vitamin C serums that I love but this one is so silky smooth and hydrating. I love the feel when it's going on to my skin. It is a little pricey but I think that it's worth it.

Oil based vitamin C serum

Love it especially during this time in the fall and then winter, help to lock in moisture in the skin with vitamin E in it

Good product, poor design

I am a fan of Yonka products and I have been using a variety of them for a while. I ordered a small travel size of vitamin C serum. It lasted a month. When I had about 1/8 of the product left, I could not use the included tool to get it out. It was too short to reach it. I had to pour it on my palms to use it. That's why only 4 stars. Otherwise, I like the feel, the smell and the overall texture of the it. I was hesitant to order a bigger size as I was not sure of the design. I would like to be able to use up all of it. I am trying a different brand but I may return to it later as I really like Yonka line. I recommend all Yonka products.

Amazing

I have been using this vitamin C serum regularly for about a month and a half. I liked the results immediately, but recently, I’ve noticed a dramatic change in the appearance of my skin. Thinking this might be my imagination, I didn’t pay too much attention to it. I ran into a friend yesterday who is a cosmetic specialist. She told me my skin looked amazing and askied me what I was doing. I attribute this to the vitamin C.

Hydrating

I like this vitamin c serum as it is very hydrating. I find that a lot of vitamin c serums could be drying. Not this one. I like the high content of vitamin c.
