Kiehl's Powerful Strength Line Reducing Concentrate Review

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?!

This gorgeous concentrate comes in pump bottle for easy dispensing and application. The lightly orange scented cream glides on and immediately imparts an amazing, velvety smooth texture which is very hydrating and gives the skin a radiant glow. The package warns that you might feel a tingling sensation but I found it warming but not in a harsh way. I use Mecca hyaluronic acid and this concentrate isn't nearly as harsh or astringent as that product. With consistent use, morning and night over the last two weeks, I do think it is softening my fine lines, particularly around the neck area where lines aren't as pronounced. I have been using three Kiehl's products in my daily routine starting with their clearly corrective dark spot solution, then using this concentrate and finishing with their super multi-corrective cream. I wait 60 seconds in between each application and find I have perfectly soft and non-greasy skin that is a great base for make-up application.

This comes in a wee bottle with a pump. One pump is usually enough to do the whole face, a wee bit more is needed to do the neck as well. This contains 12.5% vitamin C and Hyaluronic Acid. You can feel the acid the second it makes contact with your skin, a nice tingling warmth. The claim is to decrease the appearance of fine lines and wrinkles and improve radiance and texture. I've got plenty of fine lines and wrinkles!

So, how did it go? After nearly 3 weeks using this concentrate I can really see an improvement in the texture of my skin, the fine lines are perhaps not so noticeable but it does state that clinical grading of the full panel was tested in an 8 week study, so I'm going to continue and hope for even better results because I can really notice a difference.

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.

Comed in a pump action bottle. Yet again good quality packaging. Love the smell, citrusy and a little goes a long way. Apply too much and it tends to become a bit oily on the skin.

I can see a slight change in my skin appearance and texture but not much when it comes to the crows feet and deeper lines.

Will keep using the product to see if there's any significant changes after long term use.

This is a fantastic product; it comes in a 50ml dark pump bottle. The cream is a white creamy type and is easy to get out. I really like the packaging of the box and bottle, it is really easy to see that it contains 12.5% vitamin C and Hyluronic acid. It is easy to read also. You only need to use one pump for your whole face. This product does smooth the skin and reduce lines, I’m late twenties so not overly suffering from lines but it helps reduce what I do have! It had a slight numbing/warm feeling once on but did not irritate my skin at all. I have oily/combo skin and this was quite greasy on the skin
