I'm already using clearly corrective dark spot solution and midnight recovery, can I add this to my regimen? If yes, in what order would I apply the concentrate? Currently I wash my face, tone, use clearly corrective, then use midnight recovery, then moisturize.
A shopper on May 28, 2012
Best Answer: I use all three, and the difference is very clear. My skin is beautiful, and even though I am 60, people think I am in my 40's (part of that is genetics girls - please don't expect the same results!) I use the clearly corrective and line reducing concentrate twice a day, and then the midnight recovery at night. I also use a good moisturizer (Kiehl's, of course!) during the day with sunscreen ALL YEAR 'ROUND. A good cleanser and exfoliator is ESSENTIAL.

Would this help with dark spots?
lauren e on Jun 22, 2012
Best Answer: For dark spots I highly recommend Clearly Corrective Dark Spot Solution. I have definitely seen a difference in the dark spots near my eyes; I use it all over my face right after washing and find that I do not need a moisturizer! I also use it on my hands and it works well there, too. Product is not thick, heavy or greasy and has a nice "slip" to it. Am on my third bottle and will keep on buying it.

I wash my face in the morning, put this on, and do other stuff for about 20 minutes to let it "soak in." I then apply moisturizer and let it soak in for a few minutes, When I begin to apply foundation on 'spots' (not total coverage), and smooth in with foundation brush or clean sponge, the line reducing concentrate begins to "ball up" until I am down to bare skin. Everywhere. It is a hassle. I don't know what I am doing incorrectly. I use it sparingly, patting it on, not glopping it everywhere - any suggestions?
A shopper on Jun 15, 2012
Best Answer: I use this day and night. The line reducing concentrate is no 'balling up' unless you are using more than one pump on your face. You need to pump it once onto your fingertips and then pat it all over your face - don't smoothe it on until your entire face is covered with light dots. Then you can, if you need to put a little extra on your lines and creases.

Should this product be used over the whole face? Or can it be used to treat certain area's? (for example the fore head for frown lines, at the sides of your eyes for crows feet ect.)
Anne G on Apr 26, 2012
Best Answer: Yes and no. I use this product almost every night but I don't use it under my eyes. You can use it on crow's feet and, since the product spreads from the heat on your face, it gravitates to the eye area but not in full strength. I hope this helps. BTW, I love this product. When I wake in the morning my face is dewey and refreshed.

I'm 23. Will this product fit me? Any suggested age ranges for this product?
A shopper on Mar 24, 2013
Best Answer: I have been using this product for many years, but I am 56. I don't imagine at 23 you have many wrinkles. At your age, I used other products from Kiehls and I have always used moisturizer.

At your age, I would suggest that you consult with the Kiehls' staff for the proper moisturizer --- because it is important for your skin to be cared for properly.

I use a Retin-A prescription at night. Does this product contain any retinoids?
Sandi D on Sep 15, 2012
Best Answer: Not to my knowledge. I believe the ascorbic acid (10.5%) is the primary active ingredient. The ingredient list in descending order is as follows:
propylene glycol
cyclopentasilixane
ascorbic acid
glycerin
cetyl PEG/PPG-10/1
dimethicone
dimethicone crosspolyme
lauroyl lysine
acrylates copolyme
adenosine
Hope this helps, Sandi. On a personal note,
...I have VERY sensitive skin and this is the only product I can use on a daily basis...just a slight tingle on application and it really dramatically impacts fine lines/wrinkles, and evens out skin hyperpigmentation that went crazy when I was on a prescription med that caused sun sensitivity.

What is the consistency of this serum supposed to be like? I had a sample of it, and it was like a white, milky cream. I liked it a lot so I ordered the 1.7 oz. size of it. But the version in this bottle comes out as an oil, with little traces of a milky cream in it. It has the appearance of a substance that has separated and needs to be shaken. But I've shaken the bottle until I felt my arm was gonna fall off, and it hasn't changed it. Is this ok, or is there something wrong?

What would be the best follow up moisturiser for this product for normal or combination skin ... Midnight Recovery, Abyssian Cream, Intensive Corrective Moisturiser, or something else? Thanks in advance!
Jill S on Apr 16, 2012
Best Answer: I often use this alone during the day as it gives my normal/combination skin a nice finish. I don't use foundation, so the quality of my skin is important to me. I use the Midnight Recovery every night, and if my skin feels dry, I use it during the day as well. I have used the Midnight Recovery under the Line Reducing Concentrate, and that seems to produce a nice finish during the day as well... Now that the weather is warmer, dry skin isn't so much of an issue for me. If you have not purchased the Midnight Eye Cream, do try it. Totally amazing, and great for under eye shadows and puffiness.

If I use Powerful-Strength Line-Reducing Concentrate, do I need any other additional cream?
A shopper on Mar 31, 2013
Best Answer: BUY this product, it is the best. This is my go-to skin care product for anti-aging. I recommend it to EVERYONE and you notice a difference.

I do wear a cream on top mostly b/c this does not have SPF in it. However, at times I do need to alternate days when I wear the additional lotion - some days my skin feels fine, some days it feels too heavy to have both. I would recommend a light cream on top with SPF.

Can I layer this product with another serum, moisturizer and midnight recovery?
Nadia D on Mar 31, 2014
Best Answer: I do, morning and evening. It's the first thing I put on, then moisturizer. It makes your skin feel fabulous. Has it reduced my lines? I can't say for sure, but I love how it feels and will order again. I'll be 67 in 2 months, so in all fairness to the product, it would be a challenge to count lines. People always seem surprised when they learn how old I am (always thinking younger), so perhaps that's the answer. I've used it off and on for several years.

I am on accutane, would this product help restore some of the glow to my skin and smooth out some of my line around my mouth?
Tamath M. on Apr 9, 2013
Best Answer: You will see refined skin tone and lessening of the lines around your eyes and mouth with consistent use. Note that it works similarly to Retin-A, so if you have sensitive skin you'll want to start out by applying it every other night to avoid excessive redness and peeling.

Jill S on Apr 16, 2012
Best Answer: Hi Jill - I have been using this product for about a year now and love it! I am 65 years old and probably spent too much time in the sun when I was younger and a few years ago, my early sun exposure became more obvious. I love this product. It feels so good going on (it will feel warm) and leaves my skin so smooth and more even toned. I use Olay exfoliating cleanser and have never felt like I over-worked my skin. I highly recommend this product. I am also a faithful user of ABYSSINE CREAM + SPF 23. Hope this helps.

Best Answer: I would recommend the Powerful-Wrinkle-Reducing-Cream-SPF-30. This a newer cream that has come out that prevents wrinkles and contains SPF.

I have never used any of the products, I am 62 years old, I have tanned for years, have deep wrinkles all over my face. What is recommended?
A shopper on Mar 2, 2013
Best Answer: Hi! I am in the same situation -- too much sun snow skiing and scuba diving! I have found several of Kiehl's products very helpful -- but get real! -- nothing is going to erase our face showing our enjoyment of life's pleasures. Besides, it gives us character!

I use the product you asked about, Powerful-Srength Line Reducing Concentrate. Over this during the day I use Ultra Facial Cream in order to increase hydration. At night I used to use Midnight Recovery, but now supplement it with Powerful Wrinkle Reducing Cream. This last product is my Kiehl's favorite. And in the two months I have been using it, I have noticed an increased resiliency to my skin and neck.

Hope you have the success I have had.

Is this product safe for sensitive skin? I have fair skin with some redness and don't want this to make the redness worse. Thanks!
A shopper on Mar 29, 2012
Best Answer: I think the advantage for this product is that the silicon base serum will gradually release the acidity of Ascorbic Acid to your skin, therefore it will reducing the chance of skin irritation. They also do not put colors, fragrances and ingredients that may cause a problem with the skin.

I think it will be fine with sensitive skin. When you first apply to your skin, you will feel hot or burn for a few second. However, it is because of the Ascorbic Acid, not the irritation from the product.

What makes this product *work so well* is just too powerful for the delicate eye area.

Kiehl's has some really good eye creams and I recommend that. Line Reducing Eye Brightening Serum is pretty fantastic and you can couple that with your regular moisturizer.

I am 19yrs old and suffer from mild acne and I have a few lines on my forehead and laugh lines are starting to appear should I start using this product ? or will it destroy my skin?
Victoria V on Apr 21, 2014
Best Answer: I can not speak for the acne but it certainly worth a try. As for the fine lines yes it will make a big difference. The younger you start using the product the faster your skin will respond. The longer your skin will remain youthful looking. Wish I had known about Kiehl's products when I was your age.

Can I use this serum as Eye-serum? Around Eye area?

Thanks!
Sanna Y on Dec 20, 2013
Best Answer: I have found Powerful-Strength Line-Reducing Concentrate too strong to use around the immediate eye area although invaluable for wrinkles and toning for the rest of the face. I use Eye Alert for wrinkles and puffiness around the eyes because it is gentle and even when it gets in my eye does not bother me. Neither would be classified as "serums". I suggest you research "eye serums" on Kiehl's website and try a variety of free samples and then make a choice. I have tried several over the years and found them very helpful but too expensive to use on a regular basis.

What's the difference between this and midnight recovery complex?
A shopper on Jun 24, 2013
Best Answer: I have both. I use midnight serum at night, though actually you can also use it in the day time. However, it is a little bit heavy for me to put under foundation, so I use the line-reducing concentrate instead. So basically, I use midnight as my night serum, and line reducing concentrate as my day serum. Besides, the line reducing concentrate is featured with its high Vitamin C, I personally think it is more helpful antioxidant to protect skin exposing in sunlight.

can this be used under the Midnight Recovery Concentrate?
Regina C on Dec 28, 2012
Best Answer: Yes, but I don't. This cream is very strong and stands on its own. I use Midnight Recovery too but I switch them around. I believe that each cream works better if your skin gets a rest from them every so often. I have been using Powerful-Strength for more than five years and is my all time favorite product but my skin gets used to it over time and needs a rest so I usually switch to Midnight Recovery or another strong anti-aging cream for a month or so.

Howdy! I am 49 next month and with my birthday dollars am planning to purchase a kiehl wrinkle/fine line reducer. The biggest area of concern is around my eyes and compounding matters, I avoid oily moisturizers around my eyes, because they invariably smudge my waterproof mascara and around my skin, because they exacerbate my acne. My question is this: Given these parameter (acne, wrinkles, melanoma) would you think I would benefit more from - Powerful–Strength Line–Reducing Concentrate or the eye-bightener product?

Also, if I really wish to splurge, what SPF-containing, non-greasy, light or highly absorbing moisturizer would you recommend for my situation?

Thanks in advance!
LEDA S on Oct 13, 2012
Best Answer: Hello Leda - We would recommend the Powerful-Strength Line-Reducing Concentrate for crows feet and marionnette lines and the Line-Reducing Eye Brightening more for your undereyes.

For a daily moisturizer, we would suggest either Abyssine Cream + SPF 23 or Abyssine Cream + combined with the ultra-light Super Fluid UV Defense.

Happy almost birthday!

hi there, right now im using rare earth lotion morning and night, continue with midnight recovery, if i want to take this serum how to apply to get maximum work for my skin? im sulis 35yo-thanks for your answer
sulis c on Oct 3, 2012
Best Answer: Hello, Sulis c:

I can only answer you based on what I would do as a consumer: I like the serum very much, use it morning and night. Morning: serum + Ultra Facial Cream; evening: serum + Midnight Recovery. It seems a lot to me to use a lotion, serum and Midnight Recovery in the evening. I, personally, would eliminate the earth lotion at night.

I prefer not to use "jars" due to oxidation when exposed to air.
Anna-Marie B on Sep 23, 2012
Best Answer: Powerful Strength works wonders - I use this on my neck and face. You can use it at night and during the day. I dont have a lot of wrinkles so I typically only use it 3-4x's a week and on the other days I use the overnight bio-peel. This also comes in a eye formula which is great for the eye area.
