1. COSRX Advanced Snail 92 All in One Cream
£27 for 100ml
I really like the COSRX Advanced Snail 92 All in One Cream.
This moisturiser has a unique, gloopy texture because of the snail mucin. I’m not 100% sure that I dig the stringiness, as it can get a bit messy, but it’s very lightweight and absorbent.
But the moisturiser is very hydrating and non-greasy. It also feels slightly soothing.
I love that snail mucin is the first ingredient on the INCI list, showing just how high-quality it is. COSRX markets this as a snail mucin moisturiser, so it’s nice to see that the active ingredient is actually at the top of the INCI list.
All brands should follow suit! Loads of brands will market a product with a key ingredient, only for it to feature right at the bottom of the INCI list. Not cool.
Rating: 4 stars
Although this isn’t my fave moisturiser ever, I still enjoy it. And it definitely delivers a lot of hydration. My oily skin appreciates how lightweight this product is.
2. COSRX Master Patch Intensive
£13.99 for 36 patches
COSRX Master Patch Intensive is such a brilliant product. I was sceptical as to how effective they would be, but they truly work.
These transparent hydrocolloid spot patches are applied overnight to angry pimples. By morning, the spot will have dramatically reduced in size, and the redness will have improved significantly. Don’t get me wrong, the patches won’t get rid of big spots overnight, but with a couple of uses, the spot will end up completely cleared, with no irritation.
Plus, applying the sticker stops you from scratching or picking at spots.
Rating: 5 stars
I know that if I have a random pimple appear, applying one of these patches will get rid of it way faster than usual.
3. COSRX Low pH Good Morning Cleanser
£14 for 150ml
The COSRX Low pH Good Morning Cleanser is a simple yet effective cleanser. This gentle cleanser isn’t going to blow your mind, but it’s really affordable, refreshing, and non-stripping.
What I like about this cleanser is that my skin feels clean, comfortable, and mildly hydrated after using it. It’s a gel formula, which is typically my fave, and lathers easily.
I’ve used other cleansers that deliver more benefits to the skin. This COSRX one doesn’t make my skin super soft, ultra-nourished, or radiant. But it’s a good, basic cleanser that will get the job done with no irritation.
Rating: 4 stars
If you’re looking for a sensitive skin-friendly cleanser that won’t break the bank, this is a wonderful option.
4. COSRX Full Fit Propolis Synergy Toner
£26 for 150ml
The COSRX Full Fit Propolis Synergy Toner is one of the most gentle, hydrating, and soothing products I’ve used.
The thick silky texture is so satisfying to apply to the skin. Yet, it’s still lightweight and absorbent. I love how it instantly refreshes and nourishes my skin. If my rosacea ever plays up and my skin feels aggravated and warm, this toner would do wonders at calming it down.
This toner embodies everything that’s good about Korean skincare: hydrating, soothing, and gentle, with great INCI lists. I love this.
Rating: 5 stars
This is one of my fave COSRX products.
5. COSRX Aloe Soothing Sun Cream SPF50
£22 for 50ml
The COSRX Aloe Soothing Sun Cream SPF50 deserves way more hype. It’s easily one of my fave SPFs.
What I love about this SPF is that it strikes the perfect balance between being invisible and hydrating. It applies like a dream with no white cast or pilling. And it absorbs quickly too. It feels lightweight and non-greasy on the skin. But it doesn’t make your skin look flat or too matte. The SPF also delivers additional hydration and calms my skin.
If you have particularly oily skin, you could skip a moisturiser altogether and just use this SPF, because it’s nourishing. Drier skins will also love this sunscreen, as it won’t dry your skin out or cling to dry patches.
Rating: 5 stars
Honestly, this SPF is an all-around winner. I love it.
6. COSRX Advanced Snail 96 Mucin Power Essence
£23.99 for 100ml
The COSRX Advanced Snail 96 Mucin Power Essence is one of my fave COSRX products. This effective essence gives my skin everything it needs.
Firstly, this product is a must if you love the glass skin look. It makes my skin feel incredibly hydrated and look juicy and dewy. Plus, it makes my skin feel plump and elastic, which means other skincare and makeup products apply like a dream.
One of my favourite things about this powerful essence is that the hydration and dewiness last all day. It’s seriously helped contribute to healthy, hydrated, and radiant skin, and I’m here for it.
Rating: 5 stars
This essence is worth the hype it’s received on TikTok and Instagram!
7. COSRX AHA BHA Vitamin C Daily Toner
£26 for 150ml
The COSRX AHA BHA Vitamin C Daily Toner is another good product. What I like most about this exfoliating toner is that it’s very gentle, but it still works to make skin smoother and more radiant, especially as it’s enriched with vitamin C.
The exfoliator is very refreshing to apply. When I use it, my skin feels invigorated. It doesn’t irritate my rosacea either.
It’s not as effective as other exfoliators I’ve tried, but this is easy to incorporate into my weekly skincare routine for a more even complexion over time. I think this is reasonably priced too, especially when you look at the quality INCI list.
Rating: 4 stars
Although it’s not my fave exfoliator, it’s definitely worth checking out.
8. COSRX Ultimate Moisturizing Honey Overnight Mask
£23 for 60ml
The COSRX Ultimate Moisturizing Honey Overnight Mask is quite new to my skincare collection, but I absolutely love it.
Although it’s described as an overnight mask, this is essentially a night cream. You leave it on overnight and rinse it off in the morning. The texture is quite slimy, so I thought this might end up being messy or sticky. However, it’s surprisingly lightweight, absorbent, and doesn’t feel tacky once applied.
This product is very nourishing, and I can visibly notice my skin is more radiant since using this product. In fact, I’ve had compliments recently about how glowy and healthy my skin looks. And this is the only new product in my skincare routine. Plus, honey is known to help skin look more luminous. So this overnight mask seems to be the answer!
Rating: 5 stars
I love this product so far.
Overall COSRX brand review
COSRX is a brilliant brand. Its products are well priced considering that all of the INCI lists are high quality, science-backed, and feature active ingredients right at the top.
All of the products I’ve tried have been very gentle, hydrating, lightweight, and soothing. There are no super fussy or lengthy INCI lists either, making it more likely that your skin will tolerate the formulas.
What I love most about this brand is how each product meets and exceeds its claims. If COSRX says its toner will provide non-irritating exfoliation, I 100% believe it.
This is definitely one of the best skincare brands I’ve tried. I’ve got on well with every single product I’ve tried. And some products have made it into my all-time faves.
I can’t recommend COSRX enough.

Damn, this is such a good lineup! The Propolis toner speaks to me the most, I think. It sounds like a dream to use.
Great stuff 🙂 The Snail 96 in particular seems to be everywhere at the moment. I love COSRX products and you definitely feature more of my favourites here. It took me a while to work up the courage to try anything with snail mucin in it, but honestly you wouldn’t even notice it – not slimy at all!
