Kiehl's Powerful Strength Line Reducing Concentrate Review

I really love the citrusy scent of this product and the lotion-like consistency. It makes my skin feels physically smoother right after application. Moisturiser seems to glide much easier when used on top of this concentrate and my foundation seemed to lasts longer. I think it feels more like a primer than a treatment product, as everything seemed to go well on top of it, including sunscreen.

A few times I noticed my skin a tad tingly after application, esp when there's broken skin around a pimply area.

I'm not sure how much I'm supposed to use as one pump didn't seem to produce enough product to cover my entire face. I probably ended up using too much, slathering it on my neck, hoping to prevent more wrinkles from appearing.

It really is a joy to apply, even if there's no noticeable difference to my skin so far. I'll keep using it as the scent and texture of the product make me feel it's a treat for my skin and I feel my skin is plumper after application. Here's hoping it makes noticeable difference soon!

Would repurchase, especially if it manages to halt the progress of lines on my neck.

I am always on the lookout for skincare products that can improve the health and condition of my skin. Recently my skin has been in serious need of some radiance. The Kiehl’s Powerful -Strength Line Reducing Concentrate is a rich serum which contains 12 1/2% vitamin C plus hyaluronic acid, the holy grail of hydration. Vitamin C aids collagen production and helps to repair skin damaged by environmental exposure. It is supposed to minimise brown spots and pigmentation over time. The serum comes packaged in the well known white Kiehl’s box with product details and usage information clearly displayed. It is contained in an airtight, opaque bottle thus ensuring the vitamin C is not damaged by exposure to air and light. Full marks for including a pump making it hygienic and practical. The pump can be locked making it great for travelling. I apply the serum in the morning and evening, after cleansing and before my moisturiser. On application there is a slight warming sensation and my skin goes a bit red. This fades after a few minutes. There is a light citrus scent, possibly because orange and lemon oils are part of the blend. The texture of the serum is creamier and thicker than other serums I’ve used but it doesn’t feel too greasy. It is absorbed relatively quickly but if I have been heavy handed with the product I wait a few minutes than massage it in. I am in my 70s so my skin is ageing and has dry patches from indoor heating in the winter. I have been using the serum for 20 days now with pleasing results. My skin looks smoother and definitely feels softer. It is noticeable just how much fresher and brighter my complexion is. It is much more radiant and translucent. My fine lines are still there but they appear less pronounced. The dry patches on my cheeks are more hydrated. I am using the serum in conjunction with the Keihl’s Dark Spot Solution and the Multi Corrective Cream. Having a regime of targeted skincare has really contributed to my pleasing results and I will be repurchasing.

I have just started getting lines on my forehead, in my early 30s. Not deep lines but lines that are there even when I relax my face. So I was super excited to try this trio! Thanks BR! I have been using this for 3 weeks, 2 pumps in the morning and 2 pumps at night. I have definitely noticed a difference, lines on my forehead have almost disappeared! Cleanse face and use clean hands to apply in a upward direction. It has a velvety feel on the skin and slightly warm feeling, I didn't notice this until I read about it though. Packaging, simple but looks high end to me. It is a plastic pump bottle that is tinted and has a lid where you can keep it locked so good for travel. Over 3 weeks I have used a quarter of the bottle, so it should last me 3 months with 2 pumps a day. 6months with just 1 pump a day. The only problem I had was that I wasn't sure which product to use first on the skin from the trio but googled and definitely use this first before any other oils or serums creams.

Thanks BR for this little beauty!

I've never tried Kiehl's before and have been lucky enough to try 3 recently. All of them have been as fabulous as I imagine, and this is no different!

It's the perfect serum for those of us in our late 30s-early 40s, for giving those wrinkles a kick up the bum!

I've been using this after showering day and night. I'm using a couple of pumps at a time, and after 3 weeks I'm not even halfway through the bottle, so it's going to last around 2 months I think.

I experienced a slight warming sensation, which if I'd read the instructions beforehand, wouldn't have surprised me! I actually experience it everytime, which to me says there's some proper working ingredients inside!

Skin looks and feels smoother, lines are plumped up and I feel good about my skin. What more can you want from a serum?!

I am also super glad I won this. $128 for a bottle!?!? Who do these people think they are? Is there diamonds in this cream? At that price I would hope so! (There's not).

I have the 50ml bottle. The bottles is a terrible brown color with a white sticker on it, and the sticker is covered in writing. A lot of big words when they could just say "reduces wrinkles, nana!". I am quite fortunate that I don't have overly noticeable wrinkles, as I am only 24, but I think if I did have them, I would embrace them. For the sake of Beauty Review and this product, I scrutinized my face to try and find 'wrinkles' and I guess I have laugh lines around my eyes.

This product is a creamy pale yellow, but it's not opaque, it looks almost like it has yellow dots in it? They're tiny, you wouldn't be able to tell if you didn't look closely. I use a pump and rub it onto my cheeks and forehead first, and then everywhere else. I focus it around my laugh lines, and the lines around my mouth when I smile. The sensation is wonderful! As this has 10.5% vitamin C in it, it definitely warms the face.

It doesn't really have a smell, it's like a plastic citrus, mixed with something I can't quite put my finger on. I have started to use this every morning in my routine, but I really can't say for certain if it is a powerful line reducer.

I don't think I would repurchase this, mainly for the price tag, but mainly because I'm not yet worried about wrinkles. I'm still young (even younger in my head) and for now I will embrace everything, except grey hair!!!

This is expensive stuff. When I saw the price tag, I was a bit wary... I was fortunate to get a couple of samples to try before making a commitment.

I was blown away at how well this worked, honestly I didn't expect to see such results! The fine lines under my eyes were noticeably reduced, and I noticed my skin seemed brighter. I've tried a few products in the past that claimed to do both these things, but to be honest this is the first product that I actually noticed a difference right away.

I didn't notice a scent to the product, and the bottle is nothing to write home about... but it's a must have for me now after seeing the results.

I was extremely excited to be selected for a trial team for this product as Vitamin C and Hyaluronic acid are said to do wonders for dry and dull skin which, following winter and being n my mid-30's, mine certainly was.

I smooth 2-3 pumps of the Kiehl's Powerful Strength Line Reducing Concentrate to my face and neck after my serum and before my moisturiser. It is slightly warming, spreads and absorbs beautifully and smells absolutely amazing. Within a few days I was noticing a difference and my skin is radiant and glowing again.

The bottle is made with 96% post consumer recycled plastic and has a sturdy pump which I’m stoked to say has also proved leak-proof in my bag! I think it's very well priced for what it delivers but am going through this stuff very quickly and would purchase a larger bottle next time.
