Kiehl's Powerful Strength Line Reducing Concentrate Review

I haven’t heard of Kiehl’s before so at first glance— excited! Packaging looks simplistic and high end and after reading the box I am intrigued and even more excited to try! It says to cleanse thoroughly and apply under moisturizer day and night. It has a pump action nozzle that decanters a small amount, the concentrate itself is white in colour and has little to no scent. First use was interesting, after cleansing I used one pump placed between fingers and rubbed into my skin - at first contact it has a warming sensation that disappears quickly. I found one and a half pumps was a perfect amount for my face. Once applied it almost feels like a film, skin is smooth and almost matte in texture. Very easy to use and add to a daily routine. I was grateful to have a decent amount of time to trial this product and have a play with when and how to use. I especially liked using it in my morning routine - I found my foundation was more even, texture was finer and lasted longer. I think out of the 3 products in this trial this was my favourite and I credit it with most of my results. Would recommend and keep using.

Kiehl's Powerful Strength Line Reducing Concentrate has been a bit of a revelation. Due to age and previous surgery, I'm finding that I have the 'marionette line' appearing on one side of my face. I have used the concentrate as per the instructions and have definitely noticed a difference in the appearance of this line in particular. I've also noticed that my skin tone has improved as I've used it with the moisturiser. Lines around my eyes have also softened and are definitely not as obvious, which is great news! This product has a very delicate perfume and is so gentle on your skin. It is a light concentrate that penetrates the skin so quickly. Your skin definitely feels softer and looks more radiant. It is certainly a skin brightener as well and the texture of your skin is noticeably smoother. If you are struggling with these lines, then I would absolutely recommend giving this a go.

Thank you again BR for this AMAZING trial!!!

I know the price tag on Kiehl's products are above my budget so I've never bought these products - I was quick to jump on this one!! Even moreso because of my dry skin and having fine lines and wrinkles, uneven skin tone and in desperate need of a healthier complexion.

I'm a huge fan of serums, it's a daily staple in my skincare routine, day and night so I was excited to try this one - one that states it will decrease appearance of fine lines and wrinkles, and improve radiance and texture. The box does say that the clinical grading was tested in a 8 week study. I've been using this for 3 weeks and am in love! I am looking forward to what this product will do over the coming weeks.

This serum comes in a pump-style 50ml bottle, is easy to use and product comes out easily. The serum has a light fresh citrusy scent, given that it has 12.5% vitamin C I wasn't surprised.

If you're after an anti-ageing serum, this it it! I absolutely love using this, I didn't once forget to use it I was that excited to put it on my face. The serum feels like a light moisturiser on my skin and makes for even more hydration before applying the corrective solution and cream.

I have used this product together with the super corrective cream and dark spot solution and can vouch for the improved radiance and texture, together with a decrease of fine lines and wrinkles. As soon as these products are applied they are a lot less noticeable. My skin not only looks more radiant, it feels more radiant as well.

I will continue using this product over and over and recommend for anyone looking for anti-aging products.

This product is awesome.  It contains high strength Vitamin C and hyaluronic acid - very powerful active ingredients that promise to brighten and hydrate.  What impressed me most though was the way it feels on my skin.  It goes on like silk and makes my skin feel instantly smooth.  It feels like a primer because of the smooth canvas it helps to create.  The product is oil free and doesn't clog my pores.  I also didn't experience any irritation or breakouts.  What I did experience was an instant firming sensation.  The formulation is thick and creamy and it doesn't smell like anything.  It comes in a dark plastic bottle with a pump that dispenses the product without any issues.  A little really goes a long way so a 50ml bottle should last for a long time.  The product feels very nourishing, so it can be paired with a light moisturizer.  Yes, I will definitely repurchase this and I will recommend it to others.  Lovely stuff!

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

The Kiehl's Powerful Strength Line Reducing Concentrate makes me feel as if I am applying something to my skin that my Dermatologist or Pharmacist has whipped up for me on the spot! The amber bottle and simple black pump adds to the illusion. The concentrate itself is a silky white cream and has quite an odd scent, almost like petroleum, not at all fresh and herby like the other Kiehls products in the trial. The 'petroleum' smell seems appropriate though because a lovely warm sensation is experienced upon massaging the concentrate into the skin. Apparently, the concentrate has been shown to improve skin appearance and texture, help reduce the appearance of Marionette lines from the corners of the mouth, leading towards the chin. It is also meant to improve the appearance of crows feet lines and wrinkles as well as Sub-orbital wrinkles in the eye area. Does it do this? Maybe! I do have a marked improvement in my skin appearance and texture, which could also be attributed to the other Kiehls products in this trial. My lines and wrinkles have remained the same. I do feel only a syringe would deal to those! However, there is something quite magical and mysterious about this little amber bottle so I am most definitely going to continue using it in the hope that over time I will see a visible difference in all those little life lines on my face.

I've enjoyed trialling this product over the last few weeks. It feels great on my skin. I did feel the slight tingle the first few days I used it but now it glides on without any sensation. To be honest I would need to use it for longer to be able to say its made any visible difference to the texture of my skin. I will continue to use it and see how things go.
