You’ve aced Skincare 101: You drink plenty of water, log eight hours of sleep a night, and diligently apply (and reapply) SPF. But to get your advanced degree, you’ll want to invest in a targeted antiaging serum like this one from Kiehl's. Loaded with vitamin C and other potent ingredients, it smooths, brightens, and tones skin.
I like how this goes on my skin and the touch of heat after I put it on feels great but I'm not sure how much good it is actually doing. This is one that is required to use over a long period of time to see if it actually works! But, I did like this product and would think about purchasing a full size product.4
I like this brand and liked this product ok. Smelled good and felt great on my skin. Honestly could not tell a difference in fine lines. Maybe a full size & more time would see results3
This was my first birch box. I was excited for the anti aging cream. Sample was so small I would never be able to tell if it was something I would purchase. I received a dru shampoo that I won't use because my hair is so fine I am afraid it would damage it. Hopefully next month will be better. Enjoying the mascara3
I love this serum. After only a week I've noticed a difference of smoother skin. Just ordered the full size bottle!5
I only used the trial size from my box, so that may be why I didn't see any benefits. Like many other people, this would come out clearish with spots of white, and I had to reallllly shake up the tube to mix it up so it came out milky like it was supposed to. The product smells metallic to me, which I don't like.1
I have been using this product for a week, and have already noticed a change of the disappearing lines. Love this product and will be buying more when I run out of my sample!4
I loved the way it made my skin feel. It definitely does the job of smoothing out my fine lines.4
I've tried this stuff before and loved it. Now I love it even more. Fountain of Youth. Miracle drug. I can't say enough good things about this product. Wish it didn't cost so much.
I truly enjoyed opening my first Birchbox and finding this. My eyes are almost 40, so I do see some small lines. This product is amazing! Thanks Birchbox!4
I like the company and the product smelled nice, as well as help my skin feel super soft and smooth.5
