Why COSRX Is One of The Bestselling K-beauty Brands?


My skintype: Oily skin w/ large pores, some acne scars & prone to blemishes

*Reklame/PR* I was gifted a skincare set by Skinsider for review purposes about a month ago. Skinsider is a UK based, online retailer of K-beauty products that provides international shipping. They’ve created a skincare bundle in collaboration with COSRX with some bestselling products that are meant for people who want to clear out their pores and balance & even out their skintone. The bundle was limited edition and is unfortunately sold out, but the individual products are still available for purchase on their site  

It’s been around 32 days since I incorporated these COSRX products into my daily skincare routine. I’ve actually done a dedicated post where I review a bunch of COSRX products and declare my love for their brand here. In this post I’ll be reviewing four different products, some which you may have heard of or even tried for yourself and some that you may wanna get to know a bit better. 

COSRX Low pH Good Morning Gel Cleanser 150 ml: 

Let’s review the products in a chronical order, first up we have the facial cleanser. I can imagine this is one of COSRX most popular products and I can see why. It’s a beautiful lightweight, clear gel cleanser that cleanses my skin very gently but still gets any dirt and sebum off of my skin. I know the name refer to it as a morning cleanser, but it works just as well in evening as a second cleanse. It comes a simplistic white tube with a flip cap and a narrow opening to dispense the product. I like to wet my face and hands, then add a bit of cleanser in my hands, lather it up and massage it into my skin and finally rinse it off. It’s doesn’t foam up too much but there is a bit of lather going on. It does have a scent of tea tree oil which some may get offended by. Yes, the scent is a bit medicinal and herbal, but I really don’t mind. 

Ingredients: Aqua/Water, Cocamidopropyl Betaine, Polysorbate 20, Sodium Lauroyl Methyl Isethionate, Sodium Chloride, Butylene Glycol, Disodium EDTA, Caprylyl Glycol, Ethylhexylglycerin, Parfum, Allantoin, Sodium Benzoate, Trisodium Ethylenediamine Disuccinate, Citric Acid, Styrax Japonicus Branch/Fruit/Leaf Extract, 1,2-Hexanediol, Betaine Salicylate, Saccharomyces Ferment, Cryptomeria Japonica Leaf Extract, Nelumbo Nucifera Leaf Extract, Pinus Palustris Leaf Extract, Ulmus Davidiana Root Extract, Oenothera Biennis Flower Extract, Pueraria Lobata Root Extract, Ethyl Hexanediol, Limonene

Cosrx – Acne Pimple Master Patch

After cleansing I make sure to pat my face dry and usually, I would proceed on to a toner or serum. But some days we may have the occasional annoying blemish making a debut on our face and this where we wanna get our acne patches out. These are acne patches which I have really great experience with. Now I do wanna mention that these patches only work for me, when the blemish is “ripe”, this is where I see a noticeable whitehead inside the blemish. These patches are made from clear hydrocolloid that gently absorbs excess fluid like oil and sebum without drying out the area. In one pack you receive 24 patches that comes in 3 different sizes so you can use the size that is suitable for your particular blemish.

I make sure the area around my blemish is completely dry, so the patch sticks well and doesn’t move around. I stick it on and gently press on top of it and around the sides, which makes sure it slide off during the night. These patches don’t move, even if you’re like me and sleep with your face stuffed in your pillow. IT DOES NOT MOVE! In the morning I gently peel of the patches and you’ll notice your patch has turned into a cloudy white color, which is the excessive fluids the patch has absorbed through the night. My blemish is always less irritated, it’s smaller and looks a lot better. Most of the time I don’t need to treat my blemish anymore as it’ll disappear by itself but sometimes it does need another patch treatment the next day/night. 

Ingredients: Polyurethane Film, Cellulose Gum, Styrene Isoprene Styrene Isoprene Styrene Block Copolymer, Polysobutylene, Petroleum Resin, Liquid Paraffin, Tetrakismethane

Cosrx – AHA/BHA Clarifying Treatment Toner Spray 100 ml

Okay before testing this out, I did look up a couple reviews and it had quite mixed reviews. It’s a toner that contains AHA & BHA that’ll help chemically exfoliate the skin and claims to reduce the appearance of whiteheads, blackhead and blemishes. It has a very thin consistency that feels light and has a water-like texture. It’s not sticky at all and sinks into the skin within seconds, plus I like that it has no scent. It comes in a spray bottle that distributes a fine mist, but since it contains acids, I don’t like using the spray function as I want to avoid the mouth and eye area, which can be hard to avoid with the spray nozzle. I spray some on a cotton pads or in the palms of my hands and pat it in. It feels very gentle on my skin, maybe too gentle, which makes me think it’s more suitable for acid beginners.

COSRX mentions it can be used every day, but I don’t like using acids this often, so I used it 2-3 times a week instead. I don’t deal much with whiteheads or blackheads, so it’s hard for me to decide whether it helped make a difference in that department. I much prefer the COSRX BHA blackhead liquid which has been my holy grail for a while now, which is also gentle but seems to pack more of a punch.

Ingredients: Water, Salix Alba (Willow) Bark Water, Pyrus Malus (Apple) Fruit Water, Butylene Glycol, 1,2-Hexanediol, Sodium Lactate, Glycolic Acid, Betaine Salicylate, Allantoin, Panthenol, Ethyl Hexanediol.

Cosrx – Oil-free Ultra Moisturizing Lotion 100 ml

One of your final skincare steps will be a moisturizer. This one contains a whopping 70% Birch Sap that comes from the birch tree and is known for reducing inflammation, purify and hydrating the skin. It’s has a lightweight, smooth consistency and reminds me of an emulsion or even a serum. I like using a few pumps and it glides over the skin very nicely. It takes about 60 seconds for it to settle into the skin and leaves a natural/satin finish. It moisturizes my skin nicely and doesn’t feel overly heavy but provides me with enough moisture.

When I first used it I was a bit confused, cause it says it’s oil-free but once I blended it onto my skin it did feel a bit like the formula contained some form of oil or something that made it “glide” so smoothly (Yup, after looking at the ingredient list it does contain tea tree & lemon oil). This is not something negative in my book, but more of an observation. It does have a strong tea tree/menthol-like scent which can potentially be an irritant for some. Luckily my skin didn’t feel irritated, but I would prefer a less dominant scent. 

Ingredients: Betula Platyphylla Japonica Juice, Butylene Glycol, Glycerin, Dimethicone, Betaine, Cetearyl Alcohol,1,2-Hexanediol, Cetearyl Olivate, Sorbitan Olivate, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Sodium Lactate, Ethylhexylglycerin, Sodium Hyaluronate, Allantoin, Panthenol, Xanthan Gum, Ethyl Hexanediol, Citrus Medica Limonum (Lemon) Peel Oil, Melaleuca Alternifolia (Tea Tree) Leaf Oil.

From top to bottom we have the facial cleanser, oil-free lotion and the AHA/BHA toner

Before I even got to testing, my skin was actually in a quite good place. I’ve been very consistent with this set and I feel like the products have helped maintain my skin in that good position. I was a bit worried about introducing all products at once, but my skin hasn’t reacted negatively to it in any way. My favorites out of this is bundle, is without a doubt the facial cleanser and the acne patches that I rate very highly. For other interesting K-beauty products do check out or @skinsider_uk
