Kiehl's Powerful Strength Line Reducing Concentrate Review

So having used this now for 3 weeks I haven’t seen a lot of any line reduction, if anything my eyes seem to have more wrinkles! (Maybe I’m looking harder). I like the warming sensation and the feel on my skin, The skin feels smoother to touch but visibly no difference in fine lines. Will keep using though as we all know, good things do take time!

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.

I have mixed feelings on this product. I don't enjoy the texture which feels more like a primer due to the amount of silicone, making it hard to spread and I have found it never fully absorbs into my skin and leaves a tacky residue.

I used two pumps for my face and neck, sometimes an extra half pump. I do like the packaging because the pump is hygenic, it works properly and you can be precise with the amount you need. It says your skin might feel warm after application as the formula activates but I didn't notice that myself. I found that as it is high in Vitamin C, when I next cleansed, the cotton pad looked like I had wiped off a tinted moisturiser as the formula darkens when exposed to air. That doesn't bother me but it did give me a surprise at first.

My skin texture has improved somewhat which I am pleased about and my face appears slightly brighter, but I would expect more after 3 weeks of use of such a high strength product, especially as this is so expensive. I would reccomend this if my results get better soon, but considering the price and my results with this concentrate so far, I'm not sure if I will replace it for myself. I would also prefer the product without so much silicone.

I don't hate or love this product. It has a great vitamin C level, and it will help to smooth out the skins surface, immediately as well as long-term. What I didn't like about this product was the silicon feel. It creates a film over your skin, and is very hard to spread, especially if your skin is on the drier side. It doesn't seem to offer any immediate hydration, so definitely keep that in mind. Because of the silicon feel, it does have an immediate smoothing effect, and when used longterm it does smooth fine lines and improve radiance.

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

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.
