I’d like to introduce to you today, a product I used a couple of years ago, which I liked and recommended to friends, but never blogged about. I don’t even know why but its one of those things that slipped my mind 🙂 I thought I’d better remedy that, because I got very good results from this serum so I’d like to share the good news too!
The serum in question is the Kiehl’s Powerful-Strength Line-Reducing Concentrate (PSLRC for short) which is one of Kiehl’s bestsellers since its introduction in 2005. The product is, as the name implies, targeted at reducing the appearance of lines and improving skin texture, and has as its primary ingredient, Vitamin C – all 10.5% of it.
I have said this often but for some one my age (ahem!) I don’t have a serious line problem. I will count myself blessed in that respect 😉 The most prominent lines I have would be on my forehead and the naso-labial (laugh) lines. I like to think the latter isn’t that bad a thing to have 😛 So while I could not test out its claims on reducing the appearance of lines, I did notice an improvement in skin texture and skin tone. The latter was something I personally noticed, but isn’t the primary concern this product addresses.
I told you about 2 weeks ago that you could pick up samples at the Kiehl’s store and join me on my PLRC journey – did you do that? I’d love to know what you thought about this product too 😉
What this product is then, is a serum containing a high dose of Vitamin C. I’m recently learning about the benefits of Vitamin C on topical skin application and I must say that the results have been very encouraging! I first noticed the results when I was using this Kiehl’s PLRC serum.
The serum comes in a pump bottle and I find that 1 pump is usually enough although I sometimes use 2. The product itself pumps out a creamy off white when it is new. The longer you use it, I found that the colour will change to have a bit of yellow tint. Vitamin C oxidises very quickly on contact with air, so I attribute it to that. You would be well advised to store this serum in a dark place – maybe inside a drawer or cupboard and do not leave it exposed to sunlight. Kiehl’s might have thought about making the bottle totally opaque as well to reduce this oxidization.
This dollop shows you how it looks when relatively fresh. I’ve had this one a month. It isn’t very thick but neither is it runny.
On contact with skin, I notice a warming sensation which is supposed to be expected. High doses of Vitamin C can react with the skin. It isn’t unpleasant and for me, its just a very mild warming sensation that I don’t think much about. The scent is different as well. Not fragrant like most serums but not unpleasant. It smells of antioxidants 😛
The serum isn’t very fluid nor very easy to spread but I like to use the palm method to make sure it gets evenly distributed on my skin. The serum feels silky and smooth and I usually pump 1-2 pumps in my palm, spread it out between my palms and apply my palms to my face. I start with my cheeks, where sometimes gravity starts to take a toll and introduces lines, then I make sure it gets into my naso labial lines, and my forehead. You can follow up with your usual moisturizer thereafter which I usually do.
The thing is, when you work full time and then try to fit everything else you want to do in 24 hours, sometimes, it can really take a toll on your skin. During this test period, I was going through a pretty rough time at work (its not just sitting around looking pretty unfortunately!)…
…when I say I’m snowed under, I usually am quite quite snowed under! LOL!
Ohai! 😛
And then we had the new addition to the family, and I was plying the hospital route a bit, but the good thing was, my skin did not show it (well, not too much) 😀
I have since noticed an improvement in skin texture, where skin looks and feels smoother and I personally notice some skin brightening which isn’t an effect Kiehl’s tells you about, but I see it.
Powerful Duo!
But here’s the deal. I found that it delivered even better results when paired with 1 and maybe 2 other products 😉 I actually use this product like a sandwich – a Kiehl’s sandwich, if I may. It has worked very well for me, and it is one of those concoctions that I stumble upon that work, and which potentially will hurt my wallet 😛
Here’s how I like to use it – from right to left (error in product arrangement LOL!) I start with cleansing and toning, then I go on to a pre-serum and then I apply the Clearly Corrective Dark Spot Solution (review to come), then the PSLRC and then Midnight Recovery Concentrate. The recommended method by Kiehl’s is the PSLRC – Clearly Corrective – MRC but I prefer my way 🙂
Why I first started doing this was because I had been using the Clearly Corrective Dark Spot Solution in the hope to brighten my dull skin tone (its a problem I’ve been battling for a while since a botched experiment and am only now starting to see results). I figured that the PSLRC was doing a different job so I layered that on. Little did I realise that what PSLRC did was to work with the Clearly Corrective Dark Spot Solution to deliver even better results! You see, I never noticed it earlier, but both products contain Vitamin C as one of their key ingredients.
When I combined the two, I realised that my skin now looked smoother and brighter and better overall. The MRC, I included because I liked the smell and because I found that sometimes, it helped boost how other serums work. I like how it smells and everything but I didn’t think it added anything extra so its something that can be skipped if you are thinking of trying my concoction 😉
I was using it twice a day, but I’ve since cut back to once a day as I’m using a different Vitamin C serum as well. I really do think that this is a great product and one to check out, if your skin can handle it. I have read about people reacting adversely to this serum, which is likely to happen (we all have different skins) but in the main, I think most people have seen good results from this.
In a nutshell
The Kiehl’s Powerful-Strength Line-Reducing Concentrate is a serum containing Vitamin C and targets fine lines and improves skin texture. I can’t vouch for the lines, as I do not generally have that as a primary concern, but I find that my skin texture has improved and that it is smoother and more even toned generally. The serum is rather thick and has a warm sensation on skin which is supposed to be normal. I like using this serum together with the Clearly Corrective serum as I found by accident, that the results were very impressive! The latter serum helped clarify my skin tone, and the high content of Vitamin C in the PLRC helps boost that function. I’m almost sorry I strayed away from this after my first time 😛
Pros: Helped even out my skin tone and makes skin look and feel smoother, High content of Vitamin C, Works impressively well with the Clearly Corrective Dark Spot Corrector
Cons: The bottle could be more opaque to protect the contents, May not be suitable for anyone sensitive to high amounts of Vitamin C
Who will like this: Anyone who has concerns about fine lines on skin or uneven skin tone
Here is the ingredient list for anyone interested.
I like this one. It does what it says it does, and my skin looks better because of it. Sometimes, you just don’t get better that that 🙂 I hesitate to say that I will never stray. Never is a very long time. But I do know that it is something I will continue to use as long as I see the results until something better comes along 🙂
Have you tried this serum? Did you like it?
If you have picked up any samples from the store to try, I’d love to know what you thought about it 🙂

Swati says
hmmm…looks amazing. but, i have a doubt – vitamin c makes the skin sensitive to sun light so using both the products with pretty high concentration of vit. c – will it not affect the sensitivity??
Paris B says
Yep, thats why you’d need a good sunscreen daily when using products with Vitamin C 🙂 I was using it mostly at night but sometimes also in the day. I don’t go out in the sun a lot, and when I do, I make sure I don’t use it in the day
SueLin says
Hi Paris,
Thanks a lot for the review. I’m reaching mid 20s, I’ve been looking for anti aging serum to include in my routine for preventive purpose, deciding between the Estee Lauder ANR and PSLRC, can you briefly compare both?
Paris B says
Just quickly, EL ANR has retinol and has a more liquid texture. I find it good for an overall sort of serum, one I fall back on. The Kiehl’s PSLRC has Vitamin C as its primary ingredient which they say works like retinol. Both have anti-oxidants and are targeted at anti-aging. I would probably do the ANR for prevention and the PSLRC for when a hectic lifestyle starts making skin look tired. For the latter, the PSLRC seems to work better for me, while if I have a less stressful time then ANR would do. I’m not sure if that helped or if it confused you further lol!
AL says
I have tried all three and I share your sentiment – the clearly corrective dark spots solutions did nothing to my freckles.
I love the combination of PSLRC + MRC. In fact, I am almost finishing my PSLRC. Problem with PSLRC is that it is too greasy if used standalone. And I have trouble finishing it because it tends to dry up in the bottom of the bottle. I am tempted drip a few drops of MRC into the PSLRC bottle just so I can empty the bottle (Gotta be thrifty since it is not cheap for its size :P) but decided against it for fear the MRC will oxidize unused PSLRC.
Now that my PSLRC is almost finished, I am wondering if I should get the jumbo size or try out other moisturiser. Did I mention it also have some funny but bearable scent?
Paris B says
Hmm I don’t have a problem with greasiness but I otherwise agree with everything you have said. I don’t think dripping the MRC into the PSLRC would be advisable but it’s a tempting thought! lol

You make me want to buy these precious! I’ve 2 parallel deep lines on my forehead (like what we used to draw for Mathematics in high school), they’re about 5 cm each line and my mum commented that even for her age at 60, her forehead is still very smooth -_-“” “Motherrrr!!!”. Lol. I’ve been using ANR religiously in the prayer that the lines will soften. So far, zilch. Lines are lines. I reckoned it could also be due to the serious person that I am at work, sometimes I cannot help but frown or have very “real” facial expressions when I’m stressed out. Ok, should I go buy now and also attend emotion management classes? 🙂
Paris B says
Hahaha you crack me up! 😀 I don’t know if these work for deep lines. I have deep laugh lines and it doesn’t remove them but it does and can help make them look lighter. The thing about ANR I realize is that it gives skin a much needed boost but it doesnt work for lines 🙁
Ros says
Hi Paris! 🙂
The first thing I did after reading this post was to go down to Kiehl’s counter and grabbed a sample of PSLRC. And this stuff works wonders! I can see the results immediately the very next day after I use it at night. I can tell that my skin texture improves, and it also helps to clear mild acne around my chin. My friend has been using this for years and she told me it helps to reduce the lines around her neck. Thank you again for sharing this product!!! It is my HG serum now! 🙂
Paris B says
Hi Ros, I’m terribly pleased to know that the PSLRC works well for you and that you love it too! I really do think that it does work wonders on my skin and as you say, it helps improve skin texture too. Love it (and I hope I won’t stray too far too long 😉 )
annette says
Hi , do you use this pslrc only on the needed lines or do you use this all over your face? thank you paris… ; )
Paris B says
I use it all over, Annette 🙂
Meiju says
I just recently began working for Kiehl’s. It is suggested that we should not use both clearly corrective & PSLR together. Too much vit. C could irritate the skin. If anyone would like to use both products, we recommend using the CC in the morning and PSLR at night. Important note is that if you are planning to layer another booster, always do it after because CC & PSLR contain smaller molecules which makes it better for skin to absorb. ALso, MRC can always be used as a booster for any other serums 🙂
rafas says
Hi, Paris! Love your blog! Been trying out a few skincare items because of your positive feedback. Just very recently got the MRC which I hope works out great. 🙂 I have been curious about serums with retinoid as part of the ingredients. Some beauty bloggers swear by the corrective and also preventative effects of these, especially of a brand called Skin Ceuticals. Have you heard of it? It’s a drugstore brand that is a bit pricey but features in a lot of besf-of lists. Can you perhaps write about it? Would be really cool and helpful to see your feedback about their Ferulic C&E serum and their 0.5% retinoid serum…
Paris B says
Hi Rafas, thanks for coming by and for your support! 🙂 I have heard of Skinceuticals but I haven’t tried their products, which are really pricey. I have tried a similar Ferulic C&E serum in a different brand but I was a little on the fence about the results. As for retinoids, I personally do not go all out to use products with retinoids although I know it works, because that’s what everyone says it does. It helps your skin shed and renew more quickly which means scars fade more quickly and pigmentation is lightened and skin looks better. However it also makes your skin more sensitive and also more photosensitive to the sun and UV rays. That’s part of the reason I choose not to go seriously into using strong retinoids – I can’t escape the sun here, and I can’t keep reapplying sunscreen all day. So I may try a serum or two containing vitamin A and retinoids, but not a high concentrated one for these reasons 🙂

Does cleary corrective serum save to use with PLRC ?And does it really even skin tone and solve discoloration? I have some discloration because of sunAnd other discoloration , and my chin is darker than the rest of my face, and just about 2-3 acne scar not really gave acne.I have been using PLRC and the midnight and I like them and I am around 27
