This is a great mild toner, so long as you understand what it is for. This toner is not strong enough for a proper exfoliation, if you are looking for that then you can try COSRX's BHA Blackhead Power Liquid or AHA Whitehead Power Liquid. Those will give better results, but do not overuse them or you will have problems. This toner however, serves as something to be used in between days when you are not exfoliating. Since it is very very mild it doesn't sting, so it should also be good for those with sensitive skin. For oily skinned people like myself, this works well at stopping this skin from clogging up due to oil buildup. I found it especially useful at night, since usually when I wake up my skin is really oily and feels rough, but after using this daily at night (except for nights when I use another chemical exfoliant, in which case I don't combined them on the same night) I noticed that when I wake up my skin is not as oily or clogged. I use the Hydrium Toner in the morning and this at night, and so far they have both been very impressive. Definitely a great addition to the COSRX lineup.

I don’t know that any ONE product is helping fade my dark spots/acne scars, but this one is in the mix. I’ve seen some fading as well as evenness in my overall skin, which is great. Skincare is awesome, I just need to not be lazy about it

I m very disappointed by this product. I had high expectation, the formula sounded good, exfoliate and reduce after pimple red spot thanks to vitamin c. While the old red spots didn’t fade, this toner caused me six new pimples (counted) in one week. I usually have just one or two pimples just during my period, but now my face is ruined. It will take a lifetime waiting the pimple signs to go away definitely. I didn’t change other products in my skincare, just added this toner and the result was catastrophic. Very annoyed. With the same price I could have bought way better. Better western cosmetics. Never again

This product is effective for real against blackhead. i used it every day for about a week to notice visibly the improvements. it works wonder also for exfoliating, you can peel off dead skin from pimple scars as layers, so satisfying. Although the bad side is that it really dries your skin, after a week of use i changed policy and now i use it once every two days, make sure to apply a good hydratating after.

I'm so pleasantly surprised by this toner. It is great for days when you are not using an exfoliator, because it has an exfoliating effect. It helps to clear the skin without being harsh. And my skin feels smoother after using it. This is my second bottle. I would totally buy it again and again. For reference I have dry and acne prone skin.

It's perfect for dry, sensitive and dull skin. And it's very gentle for my blemish skin. Must try!

small bottle actually but the product itself is great :) definitely recommend/ buying it again maybe bigger ?

I have bought and used many different toners and find that this one left the most memorable impression on me. I had been looking to incorporate vitamin C into my nighttime routine, but couldn't decide what to get. CosRX is one of my favorite brands, so when I saw this I definitely had to get it. Do not regret purchasing it. Gentle on the skin, yet moisturizing. Might also be helping brighten my face as well. I have been using it for about 3 months now and have not had any reactions to it.

Its only my 3rd day using it but i can already see the difference in my skin! I always thought toner was not really important until my friend told me how important it is. Everyday i always woke up with some white heads or acne that never went away!
I am mainly using it in evening with cotton pads and pat some in my skin. I am waking up with no acne! I am in love with this product!

Excellent combination of ingredients - had just what I was looking for in a toner. Leaves my skin feeling great and never causes burning, stinging or driness.

Simple toner with essential ingredients. Nothing too excessive- exactly what I was looking for! Professional-looking packaging. I’m in love with COSRX’s new minimalistic packaging styles, as well as their new formulas. Can see myself repurchasing this after I finish it.

Love it so far. It feels refreshing, and doesn't feel harsh on my face. Since I've been using this product my skin feels smoother and brighter.

bought for my sister who has oily and senstive skin , she really love it!
it doesnt have a strong smell

This is already my second bottle of this cosrx toner. It does the job just fine, makes my skin really nice and soft and doesn't cause irritation even though I use it almost every day. It's very gentle, the AHAs and BHA are mostly from plant extracts. Definitely recommendable!

One of the best beauty products I've been using. cosrx in general doesn't disappoint usually but this is outstanding to me. Really gentle but still you can feel the difference. I'm up to my fourth bottle now and will keep buying it as long as I can.

my skin is really sensitive at the point that sometimes even wash with water makes my skin flares up. With this toner I didn’t experience any redness or burning. It’s not something that works overnight but after a few weeks of use i can say that it really helped me to smooth the texture of my skin. If you have sensitive skin like me you should definitely give it a try!!

another brilliant product by Cosrx. This is a very mild skin brightening toner. goes onto the skin like a dream. It has brightened by skin considerably.

Will be purchasing this over and over again.
