Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
Salicylic Acid (also known as beta hydroxy acid or BHA) is one of the most well-known ingredients for treating skin that struggles with blackheads and acne. It helps to exfoliate both the skin's surface and pores, and also acts as an anti-inflammatory agent.

Succinic acid is an odorless white powder. It is naturally found in our bodies but can also be derived from living organisms.
Sodium PCA is the sodium salt of pyroglutamic acid. It is naturally occurring in our skin's natural moisturizing factors where it works to maintain hydration.

Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.

This multitasking property makes it a great ingredient for cleaning out pores, controlling oil production, and reducing inflammation.
Unlike AHAs which are water soluble, Salicylic Acid is oil soluble. This means that it's able to exfoliate the inside of pores and reduce blackheads.
Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.
It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing a Salicylic Acid into your routine.
In general, Salicylic Acid is a great ingredient for oily acne-prone skin.
While salicylic acid does not increase sun-sensitivity, we still recommend wearing SPF.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Amazing product for combination skin with clogged pores
Atm this product may be available only in Germany, but it has amazing ingredients that offer more than another similar products of higher price range. It has 2% BHA and resveratrol, which do magic on oily skin. If you compare it to the Paula's Choice 2% BHA exfoliator, the concentration of the ingredients look pretty similar, especially the salicylic acid part, but the Liquid Refiner has additional products that help to make the skin better, and it's more affordable.
Even if this is not considered to be an "exfoliator" and more of a toner, my skin got much more smooth and "free" after this product than another BHA exfoliators, including Paula's Choice. I don't mean to say that they are bad, just that this product became a holy grail for me.

The first night I used Paula’s choice exfoliant just once, it cleaned up my skin scraping it whole, I was left GLOWING but it felt kind of tight like I had been using corsx salicylic acid for 3 days straight, it takes some getting used to, to the extent that the instructions literally say to start off once a week and slowly build your usage up overtime, it’s really strong but does the job well. I’ve noticed that if I overuse it, I get extremely coarse skin and whiteheads slowly appear in the places I use it most (my nose). This is why I highly advise to purchase the small sample bottle first and to build your way up, at MOST every other day. I’ve used it 3-4 times a week since and on the few days I don’t I use a daily-friendly exfoliant toner pad so my skin barrier isn’t destroyed but bacteria doesn’t also build. It dries up all the forehead gunk, removes residue on the sides of my nose and dried up the pimples I had been trying to rid of for so long, my skin is left gleaming, exfoliated as ever, and I know my skin wouldn’t be as flawless without it. 30ml sample version Lasted 2 months from Dec-Feb used every other day. I now use the 118ml version since Feb and there’s plenty left, will most likely last for about 7 months and 3 weeks in total (based on how long i went through the sample size). As much as I love this I deeply suggest researching and sampling because there are mixed reviews of people claiming that it ruined their skin which doesn’t surprise me -since it is pretty harsh exfoliant and skin is diverse. I tend to be wary of western products but one thing western products do well is harsh exfoliants. If you have a lot of bacterial residue, sebaceous filaments and the feeling of gunk on your face even after your exfoliant, this is a good one to consider. This combined with my Needley daily Toner pad is the only reason why my forehead looks like a glazed doughnut
I just started using it. Have used it for two nights straight and my closed comedones have reduced and my skin looks and feels better. Thanks for your advice on not using it too...
I just started using it. Have used it for two nights straight and my closed comedones have reduced and my skin looks and feels better. Thanks for your advice on not using it too frequently. I’m thinking of starting with only twice per week and using the Needly toner pad the rest of the days.
Brilliant idea Sargam, let us know how it goes! 🩷

Blackheads? Gone. Dry flakes? Gone. Nose? Smooth. Clogged pores who? My skin tends to be sensitive at times but it could easily handle this product.
