Kiehl's Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C Serum Đánh Giá

This serum contains two forms of Vi-Ta-Min C khổng lồ help brighten skin, but I'm not sure if it lives up to lớn its claims & it's very expensive.

If you’ve been reading for a while now, you may have noticed that premium skin care products are not really my thing. Actually, premium anything is not really my thing. Kiehl’s is one of those high-endish brands that does a great job of kinh doanh itself, but doesn’t really impress me much. If you actually take a cthua look at the ingredients, everything seems pretty similar khổng lồ whatever you’d find on a regular drugstore shelf. Of course, it’s definitely possible that Kiehl’s uses better suppliers for the same ingredients, but we have no way of knowing for sure. As such, I typically would never splurge on a Kiehl’s product like the one I’m going to be reviewing today, but the skin care gods granted me this và a whole bag of other samples at a Nordstrom launch các buổi tiệc nhỏ a while ago. It initially stuchồng out khổng lồ me because of its name: Kiehl’s Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C Serum. I couldn’t believe sầu how many adjectives they packed onlớn the label.


In this Đánh Giá, I’ll nói qua my thoughts on this sample, and why I don’t love sầu Vitamin C products in general, including this one.

Kiehl’s Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C Serum ingredients

propylene glycol, dimethicone, glycerin, ascorbic acid, ethylhexyl palmitate, cetyl peg/ppg-10⁄1 dimethicone, dimethicone crosspolymer, ascorbyl glucoside, cyclohexasiloxane, hydroxyethylpiperazine ethane sulfonic acid, lauroyl lysine, acrylonitrile/methyl methacrylate/vinylidene chloride copolymer, polysilicone-11, adenosine, hydrolyzed hyaluronic acid, limonene, isobutane, citrus aurantium dulcis (orange) peel oil, citrus limon peel oil/letháng peel oil, citral, pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate

It says it contains 10.5% L-Ascorbic Acid and 2% Ascorbyl Glucoside, for a total of 12.5% Vitamin C.

My Dad the Chemist’s đánh giá of Kiehl’s Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C Serum

Yes, looks like a good formula that may lighten the skin & reduce the appearance of fine line và wrinkles, but may need to lớn kiểm tra on a small area first to find out if it causes any irritation issues. Ascorbyl Glucoside will convert inkhổng lồ L-Ascorbic acid to lớn help fade dark spots & furthermore, is used to help prevent those spots.Love sầu,Dad

Kiehl’s Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C Serum review

My dad is a proponent of the formula & thinks that it may live sầu up khổng lồ its claims, at least based on its list. If you read Vitamin C guide, you know that a good Vitamin C serum should:

not set ascorbic acid with water (ascorbic acid is not stable in water-based formulas, so it won’t be as effective and vày what it claims to bởi if it’s mixed with water)be packaged in a dark/opaque container lớn reduce potential light exposurenot contain colors or dyes that help mask potential oxidation

Kiehl’s Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C Serum performs well against these three criteria, and it’s very lightweight và doesn’t feel oily when applied to lớn your skin. It also didn’t irritate my skin very much, although it did cause slight redness on those winter days when my face felt particularly dry, which is to lớn be expected. I think it also helped make my skin feel smoother temporarily because of the silicones in the formula. The bottle was small, but it lasted me about a month và a half of nightly usage. I only applied a small amount to my face each time. If you take that inlớn consideration, maybe it isn’t quite as expensive sầu as it seems at first glance.

Now onkhổng lồ the things I didn’t like so much about this serum. I can’t say that I’ve sầu ever been impressed with the “brightening” qualities of any Vitamin C serum I’ve tried, but I’ve also never tried the really expensive sầu one that everyone recommends (Skinceuticals). I don’t think it made my skin any worse, but I didn’t really notice it brightening my skin or reducing my hyperpigmentation. It did, however, deliver some psychological benefits—I felt lượt thích I was pampering my skin every night as I patted it in. It was nice, but I wouldn’t say that it’s enough of a reason khổng lồ go out and buy it at full price.

This formula contains a few ingredients that don’t strike me as necessary, including several types of citrus oils that are probably in there to lớn help lend a nice fragrance to lớn the hàng hóa. It’s like skin care manufacturers think that—since consumers automatically associate Vitamin C with oranges—it has to lớn smell lượt thích oranges or people won’t believe that it actually contains Vitamin C. Unfortunately, these types of citrusy oils can often be irritating for those with sensitivities. It also contains limonene & citral, two fragrance ingredients that may contribute khổng lồ irritation as well. Last but not least, it contains propylene glycol as the first ingredient, which probably helps lkết thúc a silky texture, but is also known lớn be irritating for sensitive skin (it was even named the American Contact Dermatitis Society’s Allergene of the Year in 2018). This hàng hóa is actually pretty similar khổng lồ Kiehl’s Midnight Recovery Concentrate in that both contain essential oils và fragrance components, though this serum contains fewer culprits than that one.

This formula reminds me of L’Oreal Paris Skincare Revitalift Derm Intensives 10% Pure Vitamin C Serum, which has a slightly lower concentration of active ingredients (10% vs. the 12.5% in this Kiehl’s product), but doesn’t contain any unnecessary fragrances or fragrance components. Give sầu that one a try if you’re looking for a less expensive, water-free Vitamin C serum.

All in all, I think if you’re truly looking for a powerful, line-reducing product, you should just use sunscreen. If you’re looking for a lightweight, water-free Vitamin C formula that combines two forms of Vitamin C & you’re not sensitive sầu khổng lồ citrus oils or fragrances, this may be the right choice for you—but for the majority of people, I don’t think I’d recommover buying it, though I wouldn’t dissuade you from trying it if you obtained a free sample.
