First try

I've never tried anti-aging products before so I was excited to get this sample in my box! One of the reasons I love Birchbox! It's very smooth and moisturizing and I don't really have any wrinkles to smooth away but I still really like it. Will definitely be purchasing.

FAN OF BRAND

I am a huge fan of this particular brand of product. I have been using my sample since I got it. I love the feel of this product, and I love the way it makes my skin feel after it has been applied to my problem areas. I have not noticed any dramatic changes, but I'm sure with a line reducing product that change will be gradual. I would recommend this to pretty much anyone even thought it is pricy their name alone has proven to produce such quality products!

Gives skin a healthy glow

With just a few uses I felt my skin looked brighter, healthier. I love how soft it immediately made my skin feel too. However, I had to use it on very specific areas because it caused a few breakouts when I used it all over.

Works well

I really enjoyed this line reducing cream. I've been using a dab or two a day and I am seeing the results already.

meh

I wasn't too impressed - tho I don't have that many lines I didn't see anything improved. I wouldn't purchase this product.

It was just ok.

I think a sample like this needs to either be bigger or not at all. there wasn't enough to start seeing a difference. I am sure it would be a good full sized product, as most of Kiehl's is!

Unpleasant tingle and greasiness

I tried this twice and am not pleased. It leaves my skin burning for about ten minutes after use and it's not a pleasant feeling. Also, I find this formula too greasy. I don't honestly believe vitamin c really makes any cosmetic difference to one's skin anyway, so this review is not based on that.

SO great!

This stuff is amazing, it makes the skin around my eyes really soft and super moisturized. I can see some wrinkle reduction as well. Which usually when a product says that it does that it doesn't work but this one actually did.

It works!

Goes on very smoothly, and has a slightt tingle burn that makes me feel like there are actually ingredients in it that work! Overall improved the appearance of my skin.
