Great product, wish I could afford it more often!

I received a sample of Kiehls Powerful-Strength Line-Reducing Concentrate a few years ago, and I have been hooked ever since! I am obsessed with this concentrate for a few reasons. The most amazing benefit is how it makes my fine lines and wrinkles COMPLETELY disappear immediately after applying, instead of just reducing them! It has noticeable long-term effects too, especially the wrinkle reducing effects. I also love the way my skin feels after applying the product, it is SO soft, and feels like velvet. The only thing I dislike about this product is its price. It costs around $70 for the full-size, which is 1.7 fl oz. A little goes a long way, but that is still a little pricey for me, and it's almost impossible to find it on sale. They do have a travel size though, which costs $22 at Ulta and Sephora, and is 0.5 fl oz. It's obviously a better deal to get the larger size, but that's often not an option for me, so I buy the travel size somewhat frequently, and the full size rarely, but whenever i am able to afford it.

Get it when it's 20% off!

This product has a silky texture that has improved the smoothness of my skin with regular use. It's a bit on the steep side, so I usually get it when it's 20% off at Kiehl's.

Great, but...

I can’t really talk about the long term effect of this serum because I only used it once, to be honest. But I can say it did felt nice on my skin. A little bit greasy and heavy at first, but then it was alright! I didn’t notice any difference because it was a sample, but it felt good.

Healthier skin that glows.

This concentrate feels amazing on my skin. It absorbs quickly and leaves the skin feeling soft and smooth and gives a nice youthful glow. My skin loves a good vitamin c product and this one did not disappoint. I also like that this also contains hyaluronic acid. My skin was left looking plump and well hydrated. Although you can wear this underneath skin cream I found my skin didn't need anything more than this. I was left with healthy, beautiful skin.

Not sure it works

I am leaving a review for this serum mainly because it is expensive. I have fairly deep lines around my mouth and bought it to decrease them and brighten my complexion in that area.

I used the product for almost two months and noticed no major differences. But perhaps it is just me. I will continue to use it until it is done just because I don't want to waste it and I spent too much money on it.

A Must Have

This product is a miracle in a bottle. The feel, the texture, and then the look makes this a must have. It keeps my face moist and helps reduce the lines. Highly recommend!

The name on the bottle says it all ..... and it works awesome, like I said I have alot of there products. I just keep changing back and forth and I no all of them work like they say they will on the bottle. I have never been so excited about a product. same with my husband he loves the men's product I bought for him for Khiel's. He asked me to buy him another one way before his runs out. Thank You Khiel's ..... THANK YOU THANK YOU THANK YOU.

My skin changed instantly with this stuff. Put it on after your toner before your moisturizer. It may tingle for the first few minutes, but then it stops and your skin just feels soft. Wish it was easier to find Kiehl's stuff in my area but I have to go downtown toronto or yorkdale. Recommend the deluxe sample from the store and you will def be back to buy it.

Wrinkles and Lines got you down? Frown no more as this Powerful-Strength Line-Reducing Concentrate is here to save the day! Formulated with a high concentration of Pure Vitamin C (L-Ascorbic Acid) this product improves the appearance of skin aging. There’s a fine line that I have been noticing on my forehead and cheek area that for the life of me don’t know how to fix … up until this product.

Amazing product. Absorbs quickly and leaves my skin feeling silky smooth. I use before bed and in the morning before applying make-up. I have only been using for 3 weeks and already notice a difference - not only with wrinkles but my skin looks healthier. The only down side to this product is the price - $60 bottle, it does last a while though as you only need one pump per application. I'll continue to spoil myself as I love the results :)
