About Kiehl’s Powerful-Strength Line-Reducing Concentrate

Kiehls Powerful Strength Line Reducing Concentrate

Kiehl’s Powerful-Strength Line-Reducing Concentrate has been a customer favourite and recently, the anti-ageing serum has been reformulated to include even more vitamin C than before.

Infused with 10.5% L-Ascorbic Acid and 2% Ascorbyl Glucoside, the new and improved formula promises even more skin benefits than it does previously.

Dermatologist-tested to ensure it’s safe for all skin types (including sensitive skin!), Kiehl’s Powerful-Strength Line-Reducing Concentrate is designed to visibly reduce the appearance of fine lines and wrinkles, boost skin radiance, improve skin’s texture, and visibly minimise pores so skin looks smoother.

Use this twice daily by applying it all over your face (avoiding eye area). You can use this alone or layered under your usual moisturiser. Note that it is normal to feel a warm sensation as the formula blends into your skin.

Kiehl’s Powerful-Strength Line-Reducing Concentrate retails at SGD105 (50ml) and SGD130 (75ml, for limited time only, while stocks last). It is available at all Kiehl’s boutiques and counters.

Within the two-week trial period, almost all reviewers saw improvements to their skin condition. The one improvement that most people noticed was how the product helped brighten their skin significantly.

Kiehls Powerful Strength Line Reducing Concentrate Review Cherie

Cherie Cheong, 30
Dry skin | Concerned with dull/uneven skin tone and visible/enlarged pores

I’ve used other vitamin C serums before but it’s the first time I’ve tried Kiehl’s Powerful-Strength Line-Reducing Concentrate. It feels warm upon application and I needed to get used to this sensation. But once I got used to it, it feels comforting especially when used as a nightly routine before sleeping. It helped brightened my dull skin and improved my dry skin condition significantly. This also helped reduce the lines associated with my skin dryness. I wasn’t expecting it to be so moisturising but it has definitely plumped up my skin. This is one of the better vitamin C serums I’ve used and I will recommend it to others.

Kiehls Powerful Strength Line Reducing Concentrate Review Shireenyin

Shireen Yin, 34
Dry skin | Concerned with dull/uneven skin tone and visible/enlarged pores

I have used vitamin C serums before but I’ve not seen any positive changes previously. Kiehl’s Powerful-Strength Line-Reducing Concentrate, however, had helped my skin look brighter, more dewy, and more radiant. I find that it’s more hydrating than the other vitamin C serums I’ve tried and it had helped reduce the appearance of my pores. I like its lightweight texture and subtle citrus smell, but most importantly, it delivers what it promised. I have already recommended this product to a loved one because I think it works!

Kiehls Powerful Strength Line Reducing Concentrate Review Wendy

Wendy Wong, 39
Combination and sensitive skin | Concerned with dull/uneven skin tone and visible/enlarged pores

My skin used to be flaky and dull but since using this serum, I wake up to glowing skin every morning. My skin tone also looks more even, and the pores around my cheek area look visibly smaller. I like that my base makeup can stay longer on my skin now and I even need less coverage than before. My skin tone looks brighter and glows naturally. In fact, people around me have noticed improvements to my skin and have asked me about it. Kiehl’s Powerful-Strength Line-Reducing Concentrate is certainly worth its price tag.

Kiehls Powerful Strength Line Reducing Concentrate Review Kym

Kym Tey, 43
Combination-dry skin | Concerned with dull/uneven skin tone, visible/enlarged pores, and pigmentation

I previously had a bad experience with vitamin C serums because I broke out very badly from using one. However, Kiehl’s Powerful-Strength Line-Reducing Concentrate has been great because I can see visible results and my sensitive skin did not suffer any breakouts or itchiness – I love it! Within two weeks of usage, I find that my skin looked more radiant and smoother, pores also look smaller, and it’s now easier to apply my foundation. It even plumped up my fine lines. However, I didn’t notice any changes to my pigmentation and it’ll probably take the product a longer time to fix the deep-set lines on my forehead. I am going to continue using the product because I think I will be able to see even better results.

Kiehls Powerful Strength Line Reducing Concentrate Review Xinyi

Chay Xinyi, 31
Combination skin | Concerned with dull/uneven skin tone, visible/enlarged pores, and pigmentation

This product is easy to apply and has a slightly warm sensation upon application. After using it day and night for three days, I find that my skin tone has brightened and looked more even. The enlarged pores around my cheek and nose areas had also significantly reduced. I do not have visible wrinkles but I do have laughing lines, but I don’t think it has improved this very much. I find that it is very effective for skin-brightening and spot-lightening – it’s better than a vitamin C serum from another brand that I’ve tried, which isn’t as good.

Kiehls Powerful Strength Line Reducing Concentrate Review Shireenho

Shireen Ho, 34
Combination and sensitive skin | Concerned with dull/uneven skin tone and visible/enlarged pores

I have used vitamin C serums from other brands before, and Kiehl’s Powerful-Strength Line-Reducing Concentrate is different in that it works while being gentle enough for sensitive skin. The product improved my complexion slightly after two weeks of usage; it became smoother, brighter, and my pores looked smaller. The pigmentation on my skin also looked lighter.

The product’s texture can be spread out easily and absorbed quickly. And the best part is that it doesn’t leave the skin feeling oily. I enjoy using this product and I always look forward to using it.

Kiehls Powerful Strength Line Reducing Concentrate Review Lisa

Lisa Kwek, 32
Combination skin | Concerned with dull/uneven skin tone and pigmentation

I have to first say that laser facials and conventional facials are a part of my skincare routine, so I have high expectations when it comes to skincare products because I think it’s almost impossible for topical products to deliver the same level of improvement to dull skin. Within the short trial period, I haven’t been able to see much improvement to my pigmentation problem. However, I believe that for any product to deliver significant results, users have to use it for at least three months, that’s why I still this serum met my expectation because it seems promising within this short trial period. I am going to continue using this product and hopefully, I can see results.

Kiehls Powerful Strength Line Reducing Concentrate Review Woan Ting

Woan Ting, 35
Combination skin | Concerned with dull/uneven skin tone, visible/enlarged pores, pigmentation, and wrinkles

While the product didn’t do much for my pigmentation and lines, I find that it helped my skin look brighter and feel smoother. One morning, I noticed that I have pillow marks on the left side of my face and after applying the product, the lines fill up almost instantly – it shows that it has an intense hydrating or smoothing effect to skin!

The product can be easily spread and absorbed very fast. It layers well under makeup and I like that it doesn’t stain the skin or leave a sharp tingling sensation like some other vitamin C serums do. I have a good impression of Kiehl’s and its products and this product didn’t disappoint. This is why I will recommend this product to those who have dull skin, but for those who have deep wrinkles or saggy skin, you may need to use it for a longer period of time to see results.

Gracelyn, 34
Combination-dry skin | Concerned with dull/uneven skin tone and pigmentation

This is one of the best serums I’ve tried and I recommended it to someone because I find that it really works. I saw a number of improvements to my skin since using it. It evened out my skin tone and brightened my complexion. My fine lines have also reduced.

I love that it sits nicely under makeup and I enjoy the warm feeling it gives when I massage the product in – it makes me feel relaxed. I am pleasantly surprised that the product works and I could see results within one week. As a bonus, I also find it affordable!

Sharon Tan, 33
Combination skin | Concerned with dull/uneven skin tone and pigmentation

There’s a slightly warm feeling on my skin upon application and the product gets absorbed rather quickly into my skin. While it hasn’t improved my pore situation, it seems to have brightened my skin and lightened my freckles. This is probably why people around me have noticed improvements to my skin and have even asked me about it. I enjoy using this product and I like that results show within a few days.
