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 Kiehl's Powerful-Strength Line-Reducing Concentrate. Loaded with vitamin C and other potent ingredients, it smooths, brightens, and tones skin. Get ready for your best skin yet.
I've never tried a product like this before and am very happy with the results. It's warm going on, and then works like a fiend to smooth my skin and deliver glowing results. I have very sensitive skin but haven't had any problems with this product.5
I am very near 50, so I'm probably older than the average user, but I have to say this product did a wonderful job of smoothing out the wrinkles on my eye lids. Used overnight, in the morning the skin is smooth and I am able to wear eye shadow on my eyes again. Haven't worn eye shadows in years because dry product on wrinkly skin just makes you look like you have scales -- gross. Very happy with this product.5
This products works great! It really smooths out the finer lines. I use it almost every morning before putting on my make up and will definitely be buying the full-size product once my sample is gone.5
I recently turned 40 and with that came a beautiful frown line on my forehead. I use Kielh's products every day and was excited to add this to my regimine. I loved it and plan to buy it!5
I adore this product! I can tell from my small sample that it does the trick! I dont have wrinkles but a few fine lines and this product def seemed to help!5
I could tell an immediate difference using this product just one night - fine lines were reduced and my skin was more even. Definitely purchasing the full size of this product.5
I just started to use the Kiel's line and I love it ! This was such a great sample to receive as soon as it is back in stock I will be purchasing the full bottle5
Can't wait to purchase more of this. I just finished my sample and will definitely be adding this to my daily routine. Thank you birchbox!5
I will be buying this! Awesome product- but I guess that's why it's out of stock! This really improved my skin after just a few days of use.5
this is one of my favorite eye creams that I have tried. It is very light yet does the work of a heavy weight. Can't wait for this to come back in stock so I can buy it!5
