This week I"m going lớn be doing a mini-nhận xét of the Cosrx AHA/BHA Clarifying Treatment Toner và comparing it lớn my trusty Mizon AHA BHA Daily Clean Toner. Why a mini-review, & not a full Đánh Giá, you might ask? You"ll see shortly.

Before we start, I just want to lớn add a note about what I expect out of these types of toners. My expectations are pretty low
, actually:
I expect them to be a suitable pH to lower my skin"s pH after cleansing khổng lồ prepare it for my actives (Vit C, BHA, and AHA),I expect them not lớn leave sầu residue on the skin that would interfere with the ability of my actives to lớn work directly in my skin,I expect them khổng lồ be non-irritating.
That"s all I need. With such minimal expectations (I pay no need lớn the brand"s claims such as"prevents whiteheads, blackheads, và blemishes with the perfect blkết thúc of all-natural ingredients và mineral water khổng lồ rejuvenate & replenish your skin." Yeah, no. It"s a just a pH-adjusting toner. Its job is lớn ready my skin for my next steps, I"m not expecting magic here. Most people don"t even need a pH adjusting toner, I just live in the desert so my skin dries out too fast lớn wait around for it lớn naturally adjust itself. But I vì chưng, và it does, so here I am. Onward!
Ingredients overview of Cosrx vs MizonA small pH testing snafu and ensuing rage-shoppingpH of Cosrx Natural BHA Skin Returning A-SolpH ofMizon 8% AHA Peeling Serum (control) and AHA BHA Daily Clean TonerpH ofCosrx AHA/BHA Clarifying Treatment TonerMy observations & experience with Cosrx vs Mizon
I"m also incredibly surly today because I realized halfway through my prep, when it was too late khổng lồ stop, that I had ordered the wrong size of chạy thử tubes. RAGE!
Let me start by saying I was really looking forward to lớn trying out the Cosrx AHA BHA toner, because I absolutely love the Cosrx BHA Blackhead nguồn Liquid, and I am reasonably satisfied with the CosrxNatural BHA Skin Returning A-Sol spot treatment.
I have repurchased 5 bottles of Mizon"s AHA BHA toner (to date) & obviously I am very happy with it, but it is constantly selling out & is hard lớn find, whereas Cosrx products have sầu been pretty easy to lớn source so far. Would the Cosrx be a dupe of the Mizon? I hoped so!
Even more encouraging was the ingredients breakdown between them, with Cosrx seeing to lớn be the clear winner:
CosrxMizon
Mineral WaterWater
Salix Albố (Willow) Bark WaterButylene Glycol
Pyrus Malus (Apple) Fruit WaterAlcohol
Butylene GlycolGlycerin
1,2-HexanediolCarica Papaya Fruit Extract
Sodium LactatePortulaca Oleracea Extract
Glycolic AcidArnica Montamãng cầu Flower Extract
WaterArtemisia Absinthium Extract
Betaine SalicylateAchillea Millefolium Extract
AllantoinGentiana Lutea Root Extract
PanthenolGlycolic Acid
Ethyl HexanediolPEG-60 Hydrogenated Castor Oil
Lactic Acid
Sodium Lactate
Salicylic Acid
Disodium EDTA
Methylparaben
Propylparaben
Fragrance

As you can see, there are a lot fewer ingredients in the Cosrx. Neither one of them have any "big" flags on Cosdna: cliông chồng here for the Cosrx Toner entry on Cosdna, cliông chồng here for the Mizon Toner entry on Cosdna. The "worst" offender is the Salicylic Acid in the Mizon toner, but of course it"s supposed to be there as that"s the BHA, và it"s in low concentration.
I notice that the Mizon has moisturizers listed much earlier than Cosrx, although it does contain alcohol which the Cosrx dos not. I would have sầu thought that would mean the Mizon would be less irritating, but I"m getting ahead of myself.
I use a digital pH meter with a two-point calibration for pH testing acids, as pH strips can react oddly with acids và give sầu inaccurate readings. I bởi still use pH strips for general products, especially things with a lot of lipids, like creams và emulsions. You can learn more about my kit here:Better Beauty Through Chemistry: Unboxing of my digital pH Meter supplies.
As I grumbled about in that post, I was unhappy with not having a suitably long-and-narrow glass container that would allow me lớn sacrifice minimal sản phẩm yet still completely immerse the electrode of the digital meter. I was unimpressed with my DIY emergency solution lớn use wine glasses, và thought I"d be all smart and get test tubes off Amazon. Designed for the purpose & all, amirite?
Well, due khổng lồ the weather delays in shipping, I received them just in the niông xã of time for this post and when I unwrapped them, my relief turned lớn disbelief, despair, and then rage very quickly.
*
Buffer liquid of pH 7.01 và buffer liquid of pH 10.01 pictured at far right.
As you can see in the image, the demo tubes are approximately twice the height my meter needs in order to lớn reach the liquid at the bottom.
I am not about khổng lồ waste an entire bottle of product khổng lồ bring the surface of the liquid up to lớn a level that the pH meter needs, so I said a bunch of really foul words that made my husb& flee khổng lồ his gaming computer (with headset) & angrily stormed onto Amazon to find 75mm thử nghiệm tubes. I would have realized that"s what I needed in the first place if I had not been too lazy to dig my digital meter out of storage and measure the darn thing.
Did you know you can buy wine on Amazon? Amazing the versatility it has. Anyway, bachồng to testing with my wine glasses "shabby chic" method.
*

That wineglass. Ugh. ANYWAY, this demo result is quite interesting because I have been asked (& have been wondering myself) where exactly this product goes in one"s routine order.
The order of your products is pretty important when you"re working with pH dependent products like actives. You can read more here:Putting your products in order, including pH dependent acids.
As I explain in that post, normally BHA goes before AHA, due khổng lồ it requiring a lower pH lớn be effective (below 4.2) & also because it"s oil-soluble & does a great job of clearing out your pores so your AHA product has a clear shot at your skin afterward. However, the A-Sol is neither high enough in concentration (according to lớn the baông chồng, it"s only 0.5% ) nor low enough pH for exfoliation.
That doesn"t mean that it"s not going lớn help your skin, as BHAs vì have other benefits even at a higher pH, but it does mean that it needs to shuffle khổng lồ the baông xã of the line và go on after you are done all your other actives. I still lượt thích to lớn give it a bit of a wait time to work on my skin before I add any layers, though.

pH result: 3.83I have tested this hàng hóa before, in theBetter Beauty Through Chemistry: Unboxing of my digital pH Meter suppliespost, but I am testing it again today for a few reasons.
One, I want to lớn show how consistently the Mizon AHA serum tests (this is my 5th bottle, & all have sầu tested in the same range), và also to lớn provide a relative sầu ph result to compare the others lớn. 3.83 is definitely firmly in the "exfoliation" range, as 4.5 is the high end for AHAs.
I also am testing this instead of the Mizon AHA BHA toner, because as you can see from the first picture on this post, I am dangerously low và could not afford khổng lồ waste the sản phẩm. However, I vị have pictures of its thử nghiệm results in the link above sầu, which came out to 4.30 for the Mizon Toner
.
Just let that sink in for a second, if you would ... the Mizon AHA BHA toner is 4.30, & natural skin pH is between 4.2 và 5.6 . The Mizon 8% AHA Peeling Serum is between 3.83 and 3.89, but it is also a serious exfoliant that I don"t use daily. Ready for the Cosrx toner result, by comparison?
Say what. And thus the great mystery of why my skin was reacting to lớn this toner is solved, at least this is the most plausible explanation in the absence of any other explicable factors. I"ll get inlớn this more below.I have no idea why this "toner" has such a low pH, because it"s really completely unnecessarily for a "prepping" step be right down-n-dirty in the exfoliating pH range. Also, this hàng hóa has low concentrations of both BHA & AHA, so it"s not even packing much exfoliation ammo lớn begin with, so why have sầu such a low pH? It makes no sense to me, & it"s overkill for what pH-adjusting toners are supposed khổng lồ vì chưng ... aka, adjust the pH of the skin after cleansing, in preparation for pH-dependent products, without irritating the skin.
As you"ve probably guessed, I"m really not happy with the Cosrx AHA BHA Clarifying Treatment Toner. It"s one of those products where my head tried to convince my skin that it was really ok:"No honest, it"s really better than the Mizon, look at the ingredients list!""But it"s so easy khổng lồ source và it"s so cheap!""Look, it comes in a handy spray bottle!"Yeah, no. Somehow, the Cosrx Toner is very irritating to my skin, and my skin loves acids. Looooves them! I tested this sản phẩm, despite the burning face effect, for a whole week, trying every application method I could think of. I applied it with a cốt tông padas Cosrx"s trang web directs, I tried spraying it onlớn my hands and then patted onto my skin lượt thích I vì with the Mizon, I even sprayed directly onlớn my face with enough distance that it was a fine mist. Nope.I tested it on the left side of my face, with the Mizon as a control on the right side of my face. From the very first application, I could feel that my left side felt hot & irritated, whereas the Mizon side was happy as usual. The sensation persisted all day, which is also uncommon for me. I figured it was the application method, but even as I switched it around in ensuing applications, the result was always the same. The Cosrx side persisted in having an irritated sensation.I even tried patch testing it on the Mizon side, just khổng lồ make sure it wasn"t some sort of inexplicable effect on only the left side (was I sleeping on my left side all of a sudden?) but nope. Same effect.This is super disappointing to me because I expected something with 1. no alcohol, & 2, fewer ingredients khổng lồ be gentler, safer on the skin, & of courseless irritating. What the heông xã, Cosrx?!I did pH demo it with my strips but got a really confounding result, so I decided to hold off until I could phối up & calibrate the digital pH meter, & when I finally pH tested everything today, it made more sense. 3.80 is sort of unnecessarily low, và therefore potentially irritating, for a hàng hóa that doesn"t contain enough concentration of acids to function as a "true" exfoliant. There is nothing wrong with something being sub-pH 4, it"s just strange that it is that low when it doesn"t actually vì anything.
As you can see in the close-up of the label, it contains only 0.1% AHA & 0.1% BHA, which is hardly enough khổng lồ justify it as its own independent exfoliator.Moreover, if it"s not meant khổng lồ be an exfoliator, why bother with a super low pH, that dips below the 4.2 threshold? Of course my immediate thought was that I must be reacting to something in the hàng hóa, but there are no flags in the ingredients for me, so I have to lớn conclude it must be the pH. I"m not convinced that the pH is the reason for the irritation, but I know others have had the same experience, so there"s something up with it. In the face of a total lachồng of anything else I can come up with lớn cause the irritation, I"m reluctantly going lớn conclude it might be the pH because there"s nothing else I can think of that would cause it.All in all, this was a huge disappointment và as you can see from the image, I"m baông chồng to my dire need khổng lồ find either a replacement for the Mizon or somewhere that stocks it so I can repurchase it. Obviously, it"s possible that my bottle was a one-off defect of some kind & it might work perfectly for you, but it"s definitely not something that I will be recommending khổng lồ anyone. Update:
After being "confirmed" discontinued by an official Mizon distributor, it"s now available again, & I"m thrilled. Where to lớn get the Mizon toner:Amazon Prime for $20|eBay for $18|Testerkorea for $25|Now I"ve got to lớn figure out if there"s a way for me khổng lồ dilute it without playing pH roulette (it"s not as straightforward as "add pH 7 water khổng lồ pH 3 liquid & get pH 5!", for example) or whether I just need khổng lồ banish it to lớn my drawer of duds & never speak of it again. Yep, it"s going to be the latter. Goodbye, CosrxAHA / BHA Clarifying Treatment Toner, we shall not meet again.Ah well, you can"t win "em all!-Cat**Disclaimer: All products reviewed/mentioned in my blog, are 100% purchased with my own money, with a single exception of a press sample I tested và reviewed in 2015 which swore me off of them forever.

Thanks so much for this Đánh Giá, Cat. I am a huge người of the Mizon Toner & have been looking for an alternative since it can be pretty difficult to find, và I've seen quite a few people buzzing about the Cosrx one so I considered giving it a try. Looks like I'll just have sầu to lớn continue hunting down my Mizon until another alternative sầu pops up!

That's interesting, because lớn me the Cosrx toner feels like putting water on my face while iirc the Mizon had a little bit of tingle. So the Cosrx feels much milder, lớn the point where I cannot tell if it's doing anything. Which was the same experience I had with the Mizon ; apart from the tingle from the alcohol there didn't seem lớn be anything. Neither one vày anything for me.

I have almost the same type of skin as you & I was really interested in getting Mizon's toner. I've been looking for it everywhere & it seems like it's sold out all over the place. I was then contemplating getting the Cosrx one, lượt thích you said is cheaper & the ingredient danh mục is shorter than the Mizon one. Not lớn sure about trying Cosrx now, where vì you think I can find the Mizon please ? (Just discovered your blog.. And I have sầu lớn say, I love your spreadsheet organization ! )

Hello! I have a question :)The CosRx A-Sol has a pH of 4.3, & not enough concentration (or low enough pH) khổng lồ exfoliate, The CosRx AHA/BHA Toner has not high enough concentration khổng lồ exfoliate, but has that super low pH of 3.85.You mentioned in another post that you lượt thích to use your Mizon AHA/BHA toner after your actives to clear the gunk off your skin before moving on lớn moisturizing agents. My question is, since the A-Sol has that higher pH and the AHA/BHA Toner has a lower pH, but neither have sầu the concentration khổng lồ exfoliate, can you phối them together & apply with a cotton pad lớn clear the gunk in the same manner you use your Mizon?I ask because I have sầu both of these products and I would like lớn get some use out of them lol.Thanks

I am going khổng lồ be writing a review on the CosRX toner & I have quite the difference experience than you. My skin loves it and there is no irritation at all. I have very oily skin, not sensitive sầu, so maybe that is it.

I seriously need help. I just bought a slew of new products lớn fill in gaps in my routine, including the Mizon AHA & BHA toner, và I can't figure out which order everything should go in. The last thing I want to vì is get it wrong and have my face blow up. I would prefer to be pretty. Would you be up for a bit of coaching? I can write up everything I'm using, all the new stuff & how I think I should be using, along with info on my skin, and maybe you can give me a tip or steer me away from something obviously wrong? I'm new khổng lồ Korean skincare & I'm feeling the newbie nerves. Thanks for your awesome article!

This was a really interesting comparison!I've sầu just recently read this post by SkinandTonic: http://skinandtonics.com/the-importance-of-fatty-acids-ph-moisture-barrier-how-i-eliminated-my-acne-decreased-my-skin-sensitivity/And am now hunting down a acid toner. The P50 raved about there will be too difficult for me lớn get, living in Europe, but that one is at a ph cấp độ of 3! So I'm considering the CosRX toner as an alternative sầu since it also has a low pH. But since you mention that this level of ph is unnecessarily low, I'm now pretty confused. Is it just because it happened lớn be irritating for you, or is there another reason this low ph is problematic? (I'm very new khổng lồ all this so sorry if I misunderstood something)

I'm a little confused as to lớn why the Cosrx Asol one is not a good pH adjuster. Per your tests, it has almost the same pH as the Mizon toner. Am I missing something?

Just one question, did you use a buffer solution during before testing a different product? Cuz that could affect pH results too.

After reading your post on other skincare products Salicylic acid being 1 and the proper order to put them in I bout the CosRX Salicylic acid daily cleanser & i cant believe the difference in my skin!! I'm going to try a few more products that you have sầu listed but am wondering if you know of a reasonably priced anti ageing/rejuvenating moisturiser?? I recently had a facial & they told me thats what I need. I have normal lớn oily skin thats dehydrated.And in your post where you said about the "crust" on your skin và needing to lớn get that off your face before being able lớn cleanse it properly... thats why I bought the salicylic acid, worked a miracle! So yeah just looking for advice on an anti ageing/rejuvenating moisturiser.Thanks a bunch!!
