Review Overview

Powerful Strength Line Reducing Concentrate is mostly slip agent, silicone, 10.5% vitamin C, more silicones, film-forming agent, and the cell-communicating ingredient adenosine. Although this is a one-note product, it’s an option if you want a stably packaged, fragrance-free vitamin C serum. The company offers this product in three different sizes. The price on this site is for smallest size, which is 1.7 ounces.

Claims

Diminishes the appearance of facial skin aging, improves overall skin texture and radiance and noticeably decreases the appearance of marionette lines, crows feet and sub-orbital lines and wrinkles.

Ingredients

Propylene Glycol, Cyclopentasiloxane, Ascorbic Acid, Glycerin, Cetyl PEG/PPG-10/1 Dimethicone, Dimethicone Crosspolymer, Lauroyl Lysine, Acrylates Copolymer, Adenosine

Brand Overview

Kiehl's At-A-Glance

Strengths: Kiehl's staff is generous when it comes to providing samples and product information; some good cleansers; a couple worthwhile serums.

Weaknesses: Expensive for what you get; the Blue Herbal and Facial Fuel products are terrible; no products to successfully address skin discolorations; the toners are disappointing; the self-tanner should be avoided; jar packaging weakens several of the formulas.

This line has been around for quite some time, and has its origins in a family-owned pharmacy based in New York City. Perhaps its neighborly beginnings with a big-city heritage are what propelled Kiehl's to its long-standing status as a popular product line. Considering that Kiehl's doesn't advertise (at least not in the traditional sense, though their products get frequent press), their brand identity and status in the minds of consumers are impressive.

What gets lost in all the fashion magazine hype and company claims of "excellence" and "quality ingredients" is that almost all of the Kiehl's products hardly warrant excitement or even mild enthusiasm. Most of them are surprisingly ordinary, with a dusting of natural ingredients almost always at the very end of the ingredient list, well after the preservatives. That amounts to little more than a token attempt to make the products appear more natural to those who want to believe a plant or vitamin must somehow be better for the skin than something that sounds more chemical. Nevertheless, that token amount is enough to allow Kiehl's to brag about how its products nourish the skin or are more environmentally friendly, when they're not.

Aside from the allure of the natural, this line consists of totally ordinary and often completely unnatural ingredients. More disheartening for skin is that many of the ingredients are of questionable benefit for those with sensitive, oily, or blemish-prone skin. In some instances product ingredients are irritating for any skin type, while half of the sunscreen products are a serious problem for reliable sun protection. If you can't resist the allure of Kiehl's, just know that the product assembly will work best for those with dry to very dry skin and that, for the money, most of the formulas aren't knock-your-socks-off thrilling.

Note: Kiehl's is categorized as a brand that tests on animals because its products are sold in China. Although Kiehl's does not conduct animal testing for its products sold elsewhere, the Chinese government requires imported cosmetics be tested on animals, so foreign companies retailing there must comply. This requirement is why some brands state that they don’t test on animals “unless required by law.” Animal rights organizations consider cosmetic companies retailed in China to be brands that test on animals, and so does the Paula’s Choice Research Team.

Smooth Sailing

I get very frustrated by the negative reviews attributed to every product but Paula's Choice products.After using Kiehl's Powerful Line Reducing Concentrate,I noticed a positive change in my skin, a smooththness I hadn't noticed before.I have been using another product from another company not reviewed well and love that one too.

5-a-day for my skin

I've been using this serum for almost 2 years and absolutely adore it - it makes my skin radiant, soft and my fine lines on forehead and aroung my month are gone! I'm 31 years-old and no one says I'm more than 26! It is a bit expensive, but definitely does the job. I also like the warm sensation it gives when absorbs, I feel like it's working immediately - a bit silly, I know, but hey!, I am actually seeing results!

Good. not the best

This is a good vit C product but I would not buy it again as I've been using the Skinceuticals ferulic and that's so much better.I'd love to try Paula's vit c booster product but I'm in the UK and it's not available here.But Keihls is worth a shot , but apart from the Vit c, there's not much to it.But I'm not downing it as it is a good product, but ther's better. I'm sticking with Skinceuticals, expensive but soooo good.

It burns!

I got 4 samples @ Nordstrom from a saleswoman of different Kiel's products. I researched from the website. 3 had a poor review . And given my luck I wasn't even going to attempt this one. Even products Paula finds non- irritating sting for me. And sure enough this one stings,burns. I've had problems with products containing vitamin C.I believe that is the reason for the irritation.I wish I could give this product a rating of all "0's".

My favorite product of all time

I'm in my 20s, so wrinkles aren't an issue for me. However, I notice my skin looks better when I have used it consistently for a week, and after 6 weeks my skin stays clear, opaque (no redness peeking through my fair skin), and new-y (more cell turnover, i think - looks like I exfoliate more consistently than I do). The pump keeps oxygen out, so it stays shelf stable for a while, and the price is very good. I've bought this at least 6 times, and everyone I have recommended it gets hooked, too.
